Current status

OpenCore Legacy Patcher 1.0.0 supports Sonoma for all models below, however some challenges remain. You can find information about them further down on this page.

Issues

Bluetooth

Sometimes Bluetooth may not work after boot on pre-2012 models. Running NVRAM reset can alleviate it.

Dual boots may also bring the issue back even after the reset.

T1 Security chip

Resolved in 1.1.0 and newer, original explainer below

::: details Support for the T1 Security chip

Sonoma has removed support for T1 chips found in most 2016 and 2017 Macs. Therefore on these systems, the following will not function:

  • Enable or disable FileVault
  • Open the Password Settings window
  • Add fingerprints (if upgrading, existing fingerprints will be deleted)
  • Add cards to Apple Pay

:::

::: warning Note that erasing the entire drive will remove the T1 firmware and it won't be reinstalled. Refer to troubleshooting for more information. :::

USB 1.1 (OHCI/UHCI) Support

For Penryn systems, pre-2013 Mac Pros and Xserve, USB 1.1 support was outright removed in macOS Ventura and naturally this continues in Sonoma. While USB 1.1 may seem unimportant, it handles many important devices on your system. These include:

  • Keyboard and Trackpad for laptops
  • IR Receivers
  • Bluetooth

Refer to the troubleshooting page on how to workaround this issue.

Graphics support and issues

This build includes both Legacy Metal and non-Metal patches for macOS Sonoma. Refer to the following links for more information about Legacy Metal and non-Metal support and their respective issues.
