In what could be a game-changer for old Mac users, the OpenCore Legacy Patcher tool is making it feasible to install the new macOS Sonoma on several older Mac models, dating back to 2008, that aren’t officially listed for this OS.
A Cost-Saving Measure for Mac Users
For users hesitating to splurge on a new Mac compatible with macOS Sonoma, this tool presents an opportunity to enjoy the latest features without the expenditure.
Coverage Beyond Official Boundaries
While macOS Sonoma is officially slated for Macs from 2018 onwards, the OpenCore Legacy Patcher extends its reach, making the OS compatible with even a 2008 MacBook. Surpassing expectations, the tool’s recent update facilitates macOS Sonoma installation on a staggering 83 unsupported Mac models.
Models Compatible with OpenCore Legacy Patcher
A brief overview of the models includes:
- 12″ & 13″ MacBooks (2008-2019)
- 11″ and 13″ MacBook Air (2009-2017)
- 13” – 17” MacBook Pro (2008-2017)
- Mac mini (2009-2017)
- 20” – 27” iMac (2007-2018)
- Mac Pro (2008-2018)
- Xserve (2008-2010)
A comprehensive list can be checked on the project’s GitHub page.

Some Restrictions Apply
While the tool offers expansive compatibility, there are certain features, like Apple’s T1 security chip support on specific MacBook Pro models, that it doesn’t cover. Yet, its use doesn’t hinder users from availing system and security updates from Apple.
Official macOS Sonoma Compatibility
Apple’s list for macOS Sonoma has notably shrunk compared to the preceding macOS Ventura. From supporting Macs till 2015 under Ventura, macOS Sonoma has limited its span to 2018 models and beyond.
The compatibility list includes the following:
- iMac Pro (2017 onwards)
- iMac (2019 onwards)
- Mac Pro & Studio (2019 and 2022 onwards respectively)
- MacBook Air, Mac mini, and MacBook Pro (all 2018 onwards)
The Technicalities and Caveats
Given Apple’s pivot towards its processors, Mac models with Intel processors now stand obsolete. The OpenCore Legacy Patcher operates as a bootloader, influencing memory over disk. Despite having outdated components like an old graphics card or Wi-Fi standard, the tool promises to rejuvenate older Macs. However, while it ensures many modern features, it doesn’t guarantee all, especially those rooted in technical underpinnings.
