The OpenCore Legacy Patcher project has released version 1.0.0 of its OpenCore Legacy Patcher, which allows owners of a large number of Macs to install and run macOS Sonoma, even though the Macs would not officially support the latest Mac operating system.
Every year, Apple releases a new version of its macOS operating system, and the updates traditionally drop support for older desktop Mac and MacBook models, usually forcing owners of the older Mac to replace them with newer hardware.
The OpenCore Legacy Patcher project, which is for a bootloader that allows newer macOS versions to work on older unsupported models, has released its latest version. The October 2 release restores support for the older Macs.
In a GitHub post announcing the release, the project announced the new version brings macOS Sonoma support to 83 unsupported Mac models. However, development is ongoing and not all features may be supported at first.
With macOS Sonoma, 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 limitation with Sonoma:
- Lack of hardware support for the T1 Security Chip
- macOS Sonoma and T1 security chip support #1103
- Applicable for 2016 and 2017 Touch Bar-based MacBook Pros
We hope as time passes, we’ll be able to tackle this issue. 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:
The list of models that can use OpenCore Legacy Patcher 1.0.0 to run macOS Sonoma includes:
- 2008 to 2019 12-inch and 13-inch MacBooks
