I know this is not a common scenario, but for the few people that upgraded a Mac originally equipped with a Core Duo processor to a Core 2 Duo processor, here is the procedure. I have an iMac version 4,1 that I upgraded years ago, and it worked. The person who found the solution had an upgraded Mac Mini. You will need a second computer that is Lion capable for this tip to work. Upgrade unsupported mac

It installs an app named Install Version Name. Open that app from your Applications folder to begin installing the operating system. MacOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion; OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard. New video here for the final release: is how to install macOS Sierra 10.12 Developer Preview on an Unsupporte.

  1. Install the package file. When promoted, enter your password and proceed with the installation. After installing the package file, the macOS Monterey installer will appear under Applications folder. Note: You can use this installer to upgrade or clean install macOS Monterey on your system. Quit the Terminal.
  2. Otherwise, you can simply skip these steps and install to your volume containg a previous version of OS X, and it'll do an in-place upgrade. 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.

As always, Make sure you have a backup of the original install! This worked for me, but always be prepared for the worst.
I made, and used, a Lion Mac OS X Install ESD on a thumb drive. Instructions to make one can be found all over the Mac centric web sites. Then follow this procedure:
  • Put the unsupported Mac in Target Disk mode and plug it into a Lion supported Mac.
  • Run the Lion installer and make sure to choose your unsupported Mac's hard drive. Let the install finish.
  • Boot back into the supported Mac's OS, and put the unsupported Mac back to target disk mode.
  • Delete the PlatformSupport.plist at /System/Library/CoreServices on the unsupported Mac's hard drive.
  • Reboot the Unsupported Mac and it should boot into Lion normally.

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.

macOS Sierra was released on Sept. 20, 2016 and officially requires a supported Mac with at least 2 GB of system memory and 8.8 GB of available storage space. (We recommend at least 4 GB of RAM.)

Officially Supported Macs

All Late 2009 and later MacBook and iMac models are supported in macOS Sierra, as are all 2010 and newer MacBook Air, MacBook Pro, Mac mini, and Mac Pro computers.

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:

Install Os X 10.12 On Unsupported Mac
  • 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

Siri comes to the Mac with macOS Sierra.

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.
