Install Mojave On 2011 Imac

Not Happy, I have a iMac 27p SSD I7 mi-2009 fast, and NO MOJAVE UPGRADE, disgusting. Last it seems that there was a deal with Microsoft to use a microsoft antialiasing software up to 2017, this would restrict Apple Mac OS to Retina display, may be this is the real reason for discarding more that 5 years old Macs that are not Retina, a number of users having non retina screens (external ),are. Fixing bad colors on 2011 iMac + MacOS Mojave (Updated) So, it was the end of the line for my 27″ 2011 iMac. After 7 years of service, the new OS (MacOS 10.14 “Mojave”) wasn’t going to be able to be installed on the old faithful. There’s some tech reasons for that – Apple moved to minimum standard for graphics cards for their system.

macOS Mojave is here and by now you may have installed it and started playing with some of its new features, like the new Continuity Camera that lets you use your iPhone as a scanner on your Mac, or the new Gallery view in Finder, or maybe the new screenshot tools.

However, it’s also possible, given that macOS Mojave is a very new release and still being fine tuned by Apple, that you’ve run into problems and need to reinstall. Thankfully, that’s very easy to do. Before we get to that, however, it’s worth eliminating one other possible cause of the problems you may be experiencing.

When you install an OS on top of another OS, and then do the same the following year when the next version comes out, your Mac accumulates lots and lots of files that it doesn’t need. These are added when applications are installed, when they’re run, and when applications like Photos, Safari, and iTunes are used. Over time these junk files can hamper the performance of your Mac. The solution is to give your Mac a cleanup. We recommend CleanMyMac X. It scans your Mac for junk files and recommends to delete them safely. It can claw back tens of gigabytes of disk space, and improve your Mac’s performance. Give it a go, you can download it for free here, and see how much disk space it can give you back.

Before you reinstall macOS Mojave

There are two types of reinstallation. One installs a new copy of macOS Mojave over the current version and leaves everything else intact. The other erases your entire startup disk and installs a clean version of Mojave. The latter is more likely to fix problems and help your Mac run faster, but you’ll have to reinstall all your applications and reconfigure all your settings.

Whichever of the two options you choose, you should back up your Mac first. If you use Time Machine to backup to an external disk or a network drive, you can restore all your applications and settings from that backup after you reinstall macOS Mojave. If you plan to run a clean reinstallation, that’s definitely the simplest route. If you prefer not to use Time Machine, you can use any other backup application, or clone your entire disk.

If you’re reinstalling because you’re going to sell or give away your Mac, you should sign out of iCloud, iTunes, and iMessage first, then run a clean installation.

How to reinstall macOS Mojave

Once you’ve backed up your Mac, you’re ready to begin the reinstallation process.

The simplest way to install macOS Mojave, and the method that Apple recommends, is to go to the App Store, find Mojave in the Quick Links section on the right hand side of the front page, click it and then follow the instructions to download and install it.

If you’re having trouble with the App Store, or you need to run a clean install, you can do the following.

1. Restart your Mac using one of the following keyboard commands:

  • Command+R — this will reinstall the version of the OS that was most recently installed on your Mac.
  • Command+Option+R — this will reinstall the latest version of the OS that is compatible with your Mac.

2. When the macOS window appears, if you’re not performing a clean installation, skip to step 7.

3. Click on Disk Utilities and choose the Erase tab.

4. Give your disk a name, choose APFS or Mac OS Extended (Journaled), and if Scheme is available, set it to GUID Partition Map.

5. Press Erase.

6. When it’s finished, quit Disk Utility to go back to macOS Utilities.

7. Choose Reinstall macOS.

8. Click Continue and follow the instructions. You’ll be asked to choose the disk you want to install macOS Mojave on, if you down’t see your startup disk, select Show All Disks.

9. Select Install and wait for the installation to complete and your Mac to restart.

If you ran a clean installation, you’ll be taken to the Setup Assistant to go through the process of reconfiguring your Mac. If you made a Time Machine backup before reinstalling, make sure it’s connected.

During setup, you’ll be asked if you want to transfer data from another Mac or a backup. Choose that option then navigate to the Time Machine backup to restore data. You’ll be given the option to transfer any or all of: Applications; user accounts; other files and folders; and computer and network settings. Choose the option you want and press Continue.

If you don’t transfer data during setup, you can do it at any time using Migration Assistant in Applications>Utilities.

Reinstalling macOS Mojave is very easy. Just make sure you backup your Mac first and download CleanMyMac X(free version) to give it a good clean up!

Important Notes:
  • Using APFS is REQUIRED in Mojave in order to receive system updates via the normal Software Update method. If you choose to continue using macOS Extended (Journaled) as your filesystem type, you will NOT receive System Updates via System Preferences. If you are not using APFS, you can follow the 10.14.1 installation steps below.

  • After applying ANY system update via Software Update, re-applying post-install patches using your Mojave Patcher installer volume will most likely be necessary. If you install a software update and the system fails to boot afterwards, this is what needs to be done.

10.14.6

10.14.6 can be updated normally via Software Update if using an APFS volume, and will need to be patched using an installer volume created with Mojave Patcher version 1.3.2 or later after installing.


10.14.5

10.14.5 can be updated normally via Software Update if using an APFS volume, and will need to be patched using an installer volume created with Mojave Patcher version 1.3.1 or later after installing.


10.14.4

Install Mojave On 2011 Imac 10

10.14.4 adds new changes that ARE NOT patchable by the post-install tool of Mojave Patcher v1.2.3 and older! Before updating to 10.14.4, you you will need to use the latest Mojave Patcher version to create a new installer volume, using the 10.14.4 installer app. Then, update to 10.14.4, either by installing via Software Update, or by just using the installer volume you've created to install.


10.14.3

If you are currently running 10.14.1 or 10.14.2, you can simply use the Software Update pane of System Preferences (if using APFS) to apply the 10.14.3 update. Once the update is installed, you will most likely need to re-apply post-install patches to get the system to boot again. This process is detailed in steps 8 - 10 above. If you are currently running 10.14.0, you'll need to proceed with the 10.14.1 update method described below.

If you are currently running 10.14.1, you can simply use the Software Update pane of System Preferences (if using APFS) to apply the 10.14.2 update. Once the update is installed, you will most likely need to re-apply post-install patches to get the system to boot again. This process is detailed in steps 8 - 10 above. If you are currently running 10.14.0, or are using a non-AFPS volume, you'll need to proceed with the 10.14.1 update method described below.


10.14.1/macOS Extended (Journaled) volumes

The Mojave 10.14.1 update does NOT install properly on unsupported machines, and could result in an unbootable OS. If you want to install the 10.14.1 update (and are not currently running 10.14.1), perform the following steps:
• Download the latest version of Mojave Patcher
• Download the installer using the Tools menu of Mojave Patcher
• Create a patched USB installer
• Boot from that, and install 10.14.1 onto the volume containing an older release.
• Once done, apply the post-install patches, and you should now be on 10.14.1.
