-- The 2007 iMac 7,1 is compatible if the CPU is upgraded to a Penryn-based Core 2 Duo, such as a T9300.
- 2006-2008 MacBooks (MacBook 1,1, 2,1 3,1 and 4,1)
- 2008 MacBook Air (MacBookAir 1,1)
-- Note: Make sure SIP is disabled on the system you intend to installHigh Sierra on. If it's not or you're unsure, just boot into your Recoverypartition of your currently installed copy of OS X, open Terminal, andrun 'csrutil disable'.
Things you'll need:
- A copy of the macOS High Sierra InstallerApp. This can be obtained from the Mac App Store using a machinethatsupports High Sierra, or by using the built-in downloading feature of the tool. In the Menu Bar, simply select 'Tools > Download macOS High Sierra...'
- A USB drive that's at least 8 GB in size
- A copy of the tool - Download here (Current version: 2.7.0, SHA1: 73f180d30200ef5f6d900440fe57b9c7d22bd6bf)
-- View changelog and download older versions here

Known issues:
- Trackpad (MacBook5,2 affected only). The trackpad in the MacBook5,2isn't fully supported in High Sierra. While it works and is fully usable,High Sierra detects it as just a standard mouse, preventing you fromchanging some trackpad-oriented settings.

How to use:
1. Insert your desired USB drive, open Disk Utility, and format it as OS X Extended (Journaled).
2. Open the 'macOS High Sierra Patcher' tool, and browse for your copy of the macOS High Sierra Installer App.
*Ensure that the tool successfully verifies the app.
3. Next, select your USB drive in the Target Volume list, and click 'Start Operation.'
4. When the operation completes, boot your target unsupported Mac offthe USB drive you just created by holding down the Option key while turning on the machine, and selecting the drive.

Note: Only perform steps 5 and 6 if you intend to do a clean install.Otherwise, you can simply skip these steps and install to your volumecontaing a previous version of OS X, and it'll do an in-place upgrade.

5. When the installer boots, open Disk Utility from the Utilities menu, or by double-clicking it in the Utilities window on the bottom left corner of the screen.
6. Select the disk or partition you want to install on, and erase it,ensuring to use either Mac OS Extended (Journaled), or APFS as the filesystem type.If formatting an entire drive, ensure GUID is selected.
-- Please note that if you use APFS, you will not have a bootable Recovery partition.
-- It is recommended that you only use APFS if the target drive is an SSD.
-- If you decide to use APFS, a custom booting method will be installed by the post-install tool, as the firmware of these unsupported machines does not natively support booting from APFS volumes. It is not quite as clean as native booting, but will not cause any issues while running High Sierra. A demo of the modified booting process can be viewed here.
7. Install macOS normally onto the desired volume.
8. When the install completes, reboot back onto the installer drive.This time, open the 'macOS Post Install' application.
9. In the application, select the Mac model you are using. The optimalpatches will be selected for you based on the model you select. You canalso select other patches of your choosing.
-- The 'i' button next to each patch will show more details about the respective patch.
10. Select the volume you have just installed macOS High Sierra on, andclick 'Patch.' When it finishes patching, click 'Reboot'. It may sitthere for a few moments rebuilding caches before rebooting.
-- If for somereason the system fails to work correctly after rebooting, boot backinto your installer drive, run the post install patch again, and select'Force Cache Rebuild' before rebooting. This isn't necessary under mostcircumstances.
11. When it reboots, it should now boot into a fully working copy ofmacOS High Sierra.
Additional Info:
- If selected in the macOS Post Install tool, your High Sierra install will have a program named 'Patch Updater' located in your /Applications/Utilities folder. This program will alert you when new updates to patches are available for your machine, and will prompt you to install them. If you do not have Patch Updater installed, but would like it, you can download and run the script found here to do so.
Updates
System updates, such as 10.13.1, should install normally if 'Software Update Patch' was selected in the macOS Post Install tool, or installed using the Patch Updater program. If for some reason updates aren't showing up, or you did not apply the patch, you can install it manually using the script found here.
-- If the machine does not start up properly after applying a system update, you will need to boot off your patched installer volume, and re-run the post-install patch on your High Sierra volume. Ensure you select 'Force Cache Rebuild' before rebooting.
FAQ:
Q: The tool created the USB drive successfully, but when booting, the progress bar hangs a bit more than half way.
A: Check your copy of the Install macOS High Sierra App. If you're using thelatest version of the tool, you must be using the latest version of theInstall macOS High Sierra App. Version 1.1 ofthe patch tool and older support older versions of the installer app.
Q: The patch tool gives me errors, such as 'Error copying files...'.
A: Check to make sure your USB drive is writeable. Try re-formatting it, or just try a different USB drive.
Q: The patch tool gives me a 'Mounting Failed' error
A: Check to make sure your Install macOS High Sierra App is the correct one.It should be around 5GB in size. If you used the 'Skip App Verification' option, you have most likely selected an invalid app thatdoesn't contain the necessary files.
Q: I cannot open my copy of Install macOS High Sierra with the patch tool.
A: If you downloaded the copy linked above, it is distributed inside aDMG file. You must open this file (mount it) to access the InstallmacOS High Sierra App you need to select.
Q: I don't see my hard drive partition in the installer screen or in the post-install tool.
A: Make sure FileVault is disabled, or use the instructions found here to unlock it manually using Terminal.
Q: I get a 'NO' symbol when starting up after successfully installing High Sierra.
A: Make sure you have run the post-install patch on the correct volume, as detailed above in steps 8-10.
Q: I get a 'NO' symbol when starting up from the patched USB drive
A: Check the supported/not supported list at the top of this page. Ensure your machine is in the supported list.
Q: My iSight camera doesn't work after installing High Sierra
A: Make sure you properly remove (using the program's uninstaller, not by simply dragging the application to the Trash) all virtual machine software installed on your machine, such as VirtualBox, VMWare, etc.
Q: I get 'NSURL' errors when trying to update my machine or use the App Store
A: This is usually the result of having an invalid CatalogURL set. To revert to stock, simply run 'sudo softwareupdate --clear-catalog' in Terminal, and then run the software update patch script located above.
Q: Safari, App Store, and/or Mail stopped working after installing a system update
A: Download and run the Onyx application, select 'Maintenence' at the top, then click the Run button.
Q: I get a 'No packages were eligible for install' error when attepting to install High Sierra
A: This is due to your system's date and time being set incorrectly. To fix it, you can either boot into your current OS X install and set the date, or you can use Terminal after booting from your patched USB installer drive to set the date. Instructions to set the date using Terminal can be found here.

For the first time since Apple released OS X 10.8 Mountain Lion in July 2012, Apple has dropped support for a number of older Macs that had supported OS X 10.8 through 10.11 El Capitan. No MacBook and iMac models prior to Late 2009 and no MacBook Air, MacBook Pro, Mac mini, and Mac Pro models prior to 2010 are officially supported by macOS Sierra, although workarounds have been developed for most unsupported 2008 and 2009 Macs.

Mac OS X is no longer being called OS X, and Apple is not promoting Sierra with a version number either (however, it is internally identified as OS X 10.12). Now it’s simply macOS Sierra – in keeping with iOS, tvOS, and watchOS.

Install Macos Sierra On Unsupported Mac

Hacking macOS Sierra for Unsupported Macs

Hardware requirements for macOS Sierre include a CPU with SSE4.1, so it cannot be run on any Mac with a CPU prior to the Penryn Core 2 Duo. In theory, it should be possible to get Sierra running on any Penryn or later Mac. It may be possible to swap out the Merom CPU in some Macs for a Penryn, which would then allow Sierra to run.

Sierra can run with 4 GB of system memory, but as with all recent versions of OS X, more memory will allow it to run even better.

Colin Mistr has published a macOS Sierra Patch Tool, which currently allows you to install and run macOS Sierra on the following officially unsupported hardware:

  • Early 2008 iMac or later
  • Mid 2009 MacBook (white) or later
  • Late 2008 MacBook Air or later
  • Early 2008 MacBook Pro or later
  • Late 2009 Mac mini or later
  • Early 2008 Mac Pro or later

Note: If you have the Early 2009 Mac Pro and have installed the firmware update patch so it identifies itself as MacPro5,1, you can run the standard installer. You do not need the patch tool.

You will need a USB drive 8 GB or larger and Mistr’s patch tool, which is linked on his page. WiFi does not function on these unsupported systems if they have the Broadcom BCM4321 WiFi module:

  • Late 2008 and Mid 2009 MacBook Air
  • Early 2008 and Mid 2008 MacBook Pro

New Features

Siri comes to the Mac with macOS Sierra.

macOS Sierra can automatically sync all files on your Desktop and in your Documents folder with other Macs running Sierra. You can also access these files in your iPhone or iPad using iCloud Drive.

The new Universal Clipboard lets you copy on one device and paste on another – whether it’s a Mac with Sierra or an iPhone or iPad with iOS 10.

Tabs are almost everywhere in Sierra, and they work much as they do in your browser. Third party apps will also be able to use tabs.

Apple Pay is now part of macOS, not just iOS.

If you have an Apple Watch, Auto Unlock will authenticate you and log you in automatically when you approach your Mac.

Optimized Storage can store infrequently used files in iCloud while keeping them immediately available any time you are online.
