Any help please?? I tried the internet recovery for a clean install on my Macbook Pro. What happens when I click install Mac OS Sierra, and I agree to continue with the installation, a popup appears with an error about unauthorized certificates or something.. Typically if there is no drive to select, then there is either no drive installed in the Mac, or the disk is failing. Same problem. Had to Erase Macintosh HD first which caused problem in the first place.
Verify disk to assure the errors are fixed, then go back to Reinstall OS X and the disk magically appeared. My MacBood Pro is a late model. Any help with this question would greatly be appreciated. A better option may be to use a USB installer drive for El Capitan or whatever version you are hoping to reinstall. Well … the install button is greyed out and i am not given any options of a disk to select. I was able to download mavericks via wifi.
Step 1: Back up!
Also, in disk utility, i cant erase or repair anything, as just about all options there are greyed out. After reading many blogs and many hours of troubleshooting, like always, comes down to the simplest thing.

When doing this OS X reinstall, you have to be connected via wire to the router or modem directly. You will have issues via WIFI…. Oh and this was recommended after an hour with Apple Care, very nice technician and very helpful as always, not sure why everyone else talks bad about Apple Care, they are always helpful to any issues i had. I have reinstalled OS X with wi-fi connections several times, it should work fine if your wi-fi router works with the Mac.
No issues. Got a White macbook late from mid Came with snow leopard. Had to change hard disk. Try running this application again. I read somewhere else that it could be my internet and that I should try a restaurant or internet cafe? Thanks a lot—appreciate so much…. Does anyone know why I cannot install from disk? I boot and press C, moves to Apple Logo and get the 3 beeps. Have changed Ram and the only way that leads me somewhere is the alt,cmd p option and I dont get the 3 annoying beeps. After 5 hours of waiting, got back to the installation telling me I had hours to go.
Well, I cancelled it, will try tomorrow on a faster line.
I hope it works that way. Using Internet Recovery I could tell it went through the download. After that I got the centered apple logo, then back to blank white-grey screen. Oddly, 3 hours ago I was able to. Now every process I have been reading about and try gets me back to the white screen. Edit: When I earlier was able to access utility, no disk errors were found.
So odd…. I got a mac Book Pro with os x maverick and i erased the files at the utility without backup of the apps. Please how do i make it work again. I erased my HD drive. After that installed mac os. After some time its giving error f. Tried on my office WiFi. Hi, so I wiped my Mac hd due to some problems with performance etc. From there I try the internet recovery and keep getting error code f. Any idea what to do? Would this work on my iMac A owned since September ?? Have basically done a factory reset, just need to reinstall OS.
Good if your internet is stable, turn it on while holding the command and R key for internet recovery mode. This will take you to the OS utilities where you will download the os from your mac directly from the apple servers. Once this is done, the partitions will appear as prompt. I went and reset my MacBook Air, and then i went to access the internet recovery bit, the bar started loading up, and about 3 quarters of the way it stopped and said F apple. I have erased HD, de-authorised from iTunes and signed out of iCloud in readiness to sell the machine — however it is only re-installing Mountain Lion — which is the version of OS X that came when purchased.
Any idea why? I format my os x and create new partitions throw Windows 7 no any sound in win7. When trying to reinstall OS or basicly do anything else, my Mac cannot find a disc. I have nowhere to install it to. Advice appreciated. Could a car run without an engine? It would do nothing. Install a hard drive, how are you supposed to re-install OS X without a hard drive?

Where is it going to go? Get it together. Be Kind.. After updating Lion from Mac OS X Snow Leopard did not include or support Internet Recovery, so it would be impossible to restore an operating system to the Mac which never included the feature. In those situations, the most recent version of OS X available will be recommended by Apple to install. OS X Mavericks is quite good, and is at least optimized for most hardware.
What goes in box with WiFi or antenna next to it? And what goes in box with lock? What do I click on check or enter.. Do I have to put in a disk to reinstall mountain lion or should something come up that I can choose from? I have followed these instructions and successfully get to the point where I can reinstall Lion. This process has repeated itself several times. Any ideas what to do from here?
Thank you. I followed the steps in this article and sure enough I got to the point where I had the option to reinstall and the OS offered was Mavericks the one which came with the MacBook Pro. This is what I wanted: Downgrade from Yosemite to Mavericks. However, since I have a second partition for my file storage separate from the system partition I clicked on that and it is now installing.
Once if it installed can I just erase the partition where I have Yosemite and get rid of it altogether so I just use Mavericks or it would be better to keep both and dual boot? Instead of re-formatting if that is the right terminology my macAir, I accidentally selected my external time machine hard drive ouch. How do I proceed? And afterwards delete the 1st partition?
At present that is one of the few things I can click on.

Disk 1 cannot be deleted because it is d place where os x utilities is installed Do nothing on this and just close the window. Now click on reinstall mac or install mac os x. Let it go. Hi, I recently bought a Mac Book Air as My Mac Book Pro failed on me and when you turned it on it went to a file on a grey screen flashing with a question mark on it? I have got macbook pro early model. Later on I upgraded it to Mavericks.
Recently I thought of upgrading it to Yosemite which I did. On successful installation I realised that It is extremely slow and found out that it is encrypting my whole hard disk. I left it for hours and hours but it looked like it stuck on that process. And also did not allow me to stop the process. I turned off my macbook using power button kind of hard stop thing. When I tried to turn it on, it stuck on safe mode and nothing was happening. I could not log back in and I tried all the diifferent methods like PRAM reset, safe mode, disk utility tool to repair the disk but nothing seemed to work.
Luckily I had backup in Time machine from last year which restored my system back to Mavericks. I started using it and it was working fine. Yesterday while closing my system I used Power button and did that forced shut down kind of thing again and since then it is not turning back on properly. From safe mode I tried to restart the system but since then it stuck on Grey Barred Circle thing. I decided to use Internet recovery method when all other methods failed including safe mode, pram reset, single user command.
Please help me. Any reason why this is happening? Or has it not taken my password? I see no horizontal progress bar, only spinning gear there. This is not a walkthrough on downgrading mac, this is a walkthrough on using Internet Recovery to reinstall OS X that came with the computer. Would this style work in this case? One day at work I found a Macbook Air in a recycling box. My boss let me keep it, if I made sure I wiped it clean. So I arrogantly booted it up, showed it to him, and did internet recovery.
I have used recovery partition several times, and it is relatively slow on WiFi , but infinitely useful way to fix serious performance issues. Therefore, once the operation is complete, you pick up where you left off, all apps and settings and docs are right where you left them and no Restore from backup is needed. I agree! Hi Jack, Ive been having this issue where first of all if I just boot the imac, it just keeps restarting over and over. This seems to happen no matter what startup commands I try.
I dont care if everything on the computer gets deleted I just want to get this thing working again. Downgrading with Internet Recovery is not a good idea at all. Mine has taken so long to get through the internet recover mode to reach the OS utilities and I think it will take longer to download the OS from the internet. I would like to know how I can install from the OS setup that i have copied to my usb drive. Name required.

If you really trip over a show-stopping error, you will almost certainly be warned about it directly, via a message alert in the Installer window.
In other words, you won't need to check the log. The log may prove useful as a diagnostic aid, however, if a problem occurs for which no other explanatory message appears. You can choose at any time to save the log to your hard drive by clicking the Save button. Returning to the main Installer window, you begin with the Introduction pane, which contains important information about the requirements for installing Mac OS X and what you need to do before installing it.
For example, it is likely to warn you about checking for firmware updates. Read the brief message and click Continue. You have now completed the Introduction. Next up is the License pane, which provides the Software License Agreement for the software you're about to install. Agree to the terms and then move on.
The error message on the bottom appeared when trying to install Mac OS X on a volume that is currently the startup disk. In this pane, you will see an icon for every mounted volume that is, each drive or partition of a drive. Some icons may include a symbol such as an octagon with an exclamation point indicating that you cannot currently install Mac OS X on that volume. If you do click the volume, a message will appear at the bottom of the window, indicating what the problem is and what you can do about it. One problem, for example, might be insufficient free disk space. Once you've selected a volume, click the Options button at the bottom of the pane.
A dialog will appear, providing the following installation options. Choose and then click OK:. This process also moves the Developer folder if one is present to Previous Systems. To replace this folder, you need to install the Developer Tools software separately. A key sub-option here is Preserve Users and Network Settings. In almost all cases, I recommend selecting this option; if you don't, you'll have to re-create your accounts from scratch.
About the only reason you wouldn't choose it would be if you thought files in your home directory were causing a problem, which you didn't want to carry over to the new installation. It may also preserve third-party software that would not get preserved via a standard Archive and Install such as certain software in the Applications folder. Note: This option does not preserve all system settings, just most of them. Most of this is minor stuff and can be easily reset if lost. Note: If you proceed past the Select a Destination pane and then use the Back button to return, the Preserve Users and Network Settings option may be dimmed and unselectable.
If so, select another volume if possible and then return to the original volume. Otherwise, you'll need to restart the Installer to reselect the option. Obviously, you shouldn't choose this option if you're installing Mac OS X on a drive that includes software you don't want to erase.
Typically, you would select the Erase and Install option only if you suspected such severe drive problems that even a Mac OS X Archive and Install would be unable to fix them. In such cases, you would want to save any critical data on the drive before erasing it. To do this, start up from another hard drive or partition assuming you can do so and back up anything you want to save from the problem volume.
Note: Alternatively, you can use Disk Utility to erase any volume other than the current startup volume at any time. To do so, launch Disk Utility, select the desired partition or disk, and click the Erase button. In the pane that appears, select a name and format for the volume, and click Erase.
This would be the approach you'd take if you wanted to use Disk Utility's "secure" erasure features described in Chapter 2. Some users recommend that you always select the Erase and Install option when you move to a major new OS version such as from This format is exactly like the ordinary Mac OS Extended format, except that all file and folder names are case sensitive. That is, a folder with the name My Memos is seen as distinct from one named My Memos. In contrast, these names would be seen as the same name in standard Mac OS Extended—in fact, you couldn't even create two folders with these names in the same parent folder; instead, you would get a message saying the name already exists.
Note: Standard Mac OS X Extended remembers that the M in Memos is uppercase; however, the name is not treated differently in searches or file databases from one with a lowercase m. The main rationale for this is that Unix is case sensitive. By setting up a server to be similarly case sensitive, it eliminates some potential problems and inconsistencies between Mac OS X's Unix base and the higher-level user interface. However, although it may make sense for certain server setups to use this format, you shouldn't use it in a client system unless you've got a specific reason to do so and are aware of the risks.
Although most third-party disk utilities have been updated for compatibility with case-sensitive file systems, not all have, and using an incompatible one could result in data loss. A repair utility that is unaware of the case-sensitive format may assume that My Memos and My memos, if in the same location, are the same folder and delete one of them. In addition, few Mac OS X applications understand case-sensitive file systems. Rather than updating an existing installation, it in essence creates an entirely new installation of system software.
Why Archive? You would use the Archive option for either of the following reasons:. The Installer refuses to update or reinstall Mac OS X, or you need to install an older version, and you don't want to reformat the drive. In Mac OS X Apple's unwelcome solution was to erase your drive if you wanted or needed to do a downgrade installation. Now you can downgrade without erasing by using Archive and Install to install the older version and then update the new installation to the latest version.
You want to preserve files from the previous OS version. In some cases, you may worry that a simple upgrade will overwrite existing files that you may wish you had saved. For example, the Installer may install a new version of an application that contains a new bug. Going back to the old version may work around this bug until the inevitable bug-fix update is released. With the Archive function, the old application version is still in your Previous Systems folder and can be returned to active duty—assuming it works in Mac OS X.
Similarly, you may want to replace some modified settings files—especially in the Unix software—with the new ones installed by Mac OS X, as detailed later in this sidebar.

For minor upgrades, such as from Mac OS X Instead, your only option is Upgrade. However, if you're performing a major reference upgrade that is, where there is a change in the first number after the decimal, such as from Mac OS X There's very little downside to this option, other than the additional disk space required to store the archived software. Reinstalling software and resetting preferences after an Archive installation. After an Archive and Install, you may need to reinstall some third-party software to get it to work properly. You may also need to reset some serial-number registrations.
For example, I needed to re-enter my QuickTime Pro serial number. For example, when upgrading from Mac OS X I also had to re-enable the Network Time check in the same preferences pane. Moving files after an Archive installation. After an Archive clean install, the archived OS software in the Previous Systems folder may contain a few files that you want to return to the now-current OS.
As a general rule, I wouldn't move anything back until you discover that a setting or feature is missing and you can't re-create it easily by entering new settings. This way, you avoid the problems that can occur if you replace a needed newer file with an older one. That being said, included among the items you may want to move back are the following:.
If you do decide to transfer files back, you may be blocked from moving certain files due to insufficient permission access. In such cases, you will need to use techniques to modify permissions or authenticate the moves such as those described in Chapter 6 so that you can bypass this blockade. Deleting files after an Archive installation: Help files. You may want to delete some files that were carried over from the old home directory to the new one. Transferring Unix files. In particular, you may want to move the following files and folders:.
You may need to log in as a root user or launch a file utility as root to make some of these changes. Using the Previous Systems folder. One weakness of the Archive option is that the archived system is not bootable. In addition, the Installer does not offer a "switch back" option.
Thus, if you decide that upgrading was a mistake which is very unlikely! For that reason, make sure that your Mac OS X volume is backed up before doing the upgrade. Then if you decide to go back, you can restore the old Mac OS X version from your backup. Note: The application software in the Previous Systems folder—all older versions of "stock" Mac OS X applications that have been replaced by newer versions—remains functional.
Thus, if you double-click a document that uses one of these applications and a newer version is not available elsewhere, the document will attempt to launch via the application in the Previous Systems folder. Preserve Users and Network Settings. But what if you did not use it and later wish you had? Good news: You can still restore your home directory; it will just be more work to do so.
What you will need to do is create a new account for yourself, using the same short name as your old account. You can then copy files from the old account into the new one. You may need to reset permissions of some files, making yourself the owner, before you can use them. You can repeat this for any additional accounts you may have that you want to re-create. Deleting Previous System folder. After updating, you may eventually decide you no longer need any of the files stored in the Previous System 1 or 2, and so on folder and want to delete the folder to regain the disk space.
If your account has administrator status, you can simply drag the folder to the Trash; if you're asked to authenticate, provide your user name and account password. When you make custom changes to a config file, the changes may be wiped out when you update to a new version of Mac OS X. This is because the update often replaces the customized config file with an updated default copy of the file. It will appear that all of your customized changes have been lost. In some cases, the Installer nicely preserves the customized file in the same directory, adding an extension to the filename, as in httpd.
This allows you to recover your changes and add them back to the new file. Alternatively, you can swap the files so that the inactive file is returned to active duty. For example, for the httpd. Doing this httpd. However, starting with the installer package for the Mac OS X The Installer checks to see if you have modified the existing httpd. If you have not, then it automatically replaces it with the new version. At your leisure, you should add your modifications to the new file and retire the old one. Major Mac OS X upgrades typically defined as one in which the first digit after the decimal point changes, such as from From this disc, you can install a new, full version of Mac OS X, even on an empty volume.
Between major updates, however, Apple releases minor updates. These free updates are available via Software Update or by downloading the update file from the Web. Such updates, however, can be applied only to already installed versions of Mac OS X and sometimes only to the most recent prior version.
You will be able to upgrade only from an existing older version of Mac OS X. This limitation is significant, as it prevents you from using one of the key install features of Mac OS X: Archive and Install. Tiger upgrade discs do include an Archive and Install option. However, it works only to upgrade a volume that is presently running Panther. You could not use this option, for example, to downgrade from Mac OS X For such cases, you need the full Install disc. Finally, you'll reach the pane where you actually initiate the installation.
By default, the Easy Install pane appears unless your drive has insufficient disk space. At this point, you can simply click the Install or Upgrade button and then sit back and relax. You have now reached the Installation stage. The installation may take 20 minutes or so to complete, during which time a variety of status messages appear, informing you of what is happening at each stage. Unless something goes wrong and the installation fails, you're finished with the installation process.
Rather than doing an Easy Install, you can click the Customize button to bring up the Custom Install pane. From here, you can enable or disable individual components of the installation—which means you can disable options you don't need in order to save drive space or simply reduce clutter. This is also how you install software that would otherwise not be installed.
When you select a Custom Install option in the list, the bottom of the window shows a description of that item; to the right of the item you can see how much space it will require on your hard drive. When you're done configuring your Custom Install, click the Install button to begin installation. If you change your mind and want to do an Easy Install instead, click the Easy Install button. When installation is complete and you reach the Finish Up pane , you can choose to restart by quitting the Installer.
If you don't, the Installer will restart automatically after a brief delay. When you restart, the Mac should start up from the volume where you just installed or upgraded Mac OS X. If it instead boots from the Install disc, restart again and hold down the Eject key or mouse button until the disc ejects. The additional software on these discs is then installed. If this is the first time you've installed Mac OS X or if you did an Erase and Install or an Archive and Install without preserving user accounts , you will be prompted to set up an account for yourself, as well as Internet access, before you can log in.
Otherwise, the Login window will appear or you will be automatically logged in, depending upon your preferences. Even if you've just installed Mac OS X, there may be minor updates that are newer than the installed version. For this reason, once you've successfully installed Mac OS X, you should run Software Update to check for and then install any updates. If you're connected to the Internet on login, Software Update may launch automatically. Alternatively, if you previously downloaded the update files, you can install them directly from the.
