With the release of OpenCore Legacy Patcher 2.0.0, we're proud to announce macOS Sequoia support! And with it, 83 unsupported Mac models will be able to run Apple's latest operating system!
With macOS Sequoia, we spent many months working tirelessly to get these old machines running. And because of the sheer number of different hardware we support and the challenges of working on a closed-source operating system, not all features are currently available.
Main limitations with macOS Sequoia:
- Lack of support for recently dropped 2018 T2 MacBook Airs (MacBookAir8,x).
- Single CPU limitation on 2008 Mac Pro (MacPro3,1) and 2008 Xserve (Xserve2,1).
- Booting with more than 4 cores breaks Sequoia, OpenCore Legacy Patcher will automatically disable additional cores.
- When running an older OS, you can disable this limitation in Settings.
- Photos Application is non-functional for non-Metal-based graphics cards.
- Applicable for pre-2012 Macs (See table below).
Non-Metal Graphics Models:
- MacBook5,1 - MacBook7,1 (Early 2008 - Mid 2010)
- MacBookAir2,1 - MacBookAir4,x (Mid 2008 - Mid 2011)
- MacBookPro4,1 - MacBookPro8,x (Late 2008 - Late 2011)
- iMac7,1 - iMac12,x (Mid 2007 - Mid 2011)
- Macmini3,1 - Macmini5,x (Early 2009 - Mid 2011)
- MacPro3,1 - MacPro5,1 (Early 2008 - Mid 2012)
Affected GPU Models (click to expand)
| Vendor | Architecture | Generation |
|---|---|---|
| AMD | TeraScale 1 and 2 | 2000 - 6000 series |
| Nvidia | Tesla | 8000 - 200 series |
| Nvidia | Maxwell and Pascal | 900 - 1000 series |
| Intel | Iron Lake | HD series |
| Intel | Sandy Bridge | HD 3000 series |
We hope as time passes, we'll be able to tackle these issues. However for now, we're unable to provide any timeline when it'll be resolved.
Additionally we recommend users check the graphics issues to see what may not be fully supported:
- Legacy Metal Graphics Support and macOS Ventura - Sequoia #1008
- Legacy Non-Metal GPUs and MacOS Big Sur - Sequoia #108
As to be expected, macOS Sequoia support is still in active development. This is a community-driven project, and as such we ask users to keep expectations in check and use older OSes if you encounter issues that affect you.
