# macOS Sonoma Support
|
|
|
|
|
|
|
|
*Well here we are again, it's always such a pleasure~*
|
|
|
|
Apple has yet again dropped a bunch of models, continuing their journey on discontinuing Intel Macs. With the release of OpenCore Legacy Patcher 1.0.0, early support for macOS Sonoma has been implemented.
|
|
|
|
## Versioning
|
|
|
|
With 1.0.0, we'll be switching to a proper major, minor and bug fix system ([Semantic Versioning](https://semver.org/)). This means the coming release will be version 1.0.0, and future releases plan to follow this scheme:
|
|
|
|
- First digit: Major changes, including new OS support, API changes, and significant patch set changes, etc
|
|
- Second digit: Minor changes, including incoming OS update fixes, minor patch set changes, etc
|
|
- Third digit: Bug fixes, primarily hot fixes either due to a regression in prior release or resolving issues in already released OS updates
|
|
|
|
|
|
## Newly dropped hardware
|
|
|
|
* MacBook10,1: MacBook (Retina, 12-inch, 2017)
|
|
* MacBookPro14,1: MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)
|
|
* MacBookPro14,2: MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports)
|
|
* MacBookPro14,3: MacBook Pro (15-inch, 2017)
|
|
* iMac18,1: iMac (21.5-inch, 2017)
|
|
* iMac18,2: iMac (Retina 4K, 21.5-inch, 2017)
|
|
* iMac18,3: iMac (Retina 5K, 27-inch, 2017)
|
|
|
|
## Current status
|
|
|
|
OpenCore Legacy Patcher 1.0.0 will support Sonoma for all models normally supported by the Patcher, however some challenges remain. You can find information about them below.
|
|
|
|
## Issues
|
|
|
|
* [Bluetooth](#bluetooth)
|
|
* [T1 Security chip](#t1-security-chip)
|
|
* [USB 1.1 (OHCI/UHCI) Support](#usb-1-1-ohci-uhci-support)
|
|
* [Graphics support and issues](#graphics-support-and-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
|
|
|
|
::: details Support for the T1 Security chip (Resolved in 1.1.0 and newer)
|
|
|
|
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.
|
|
:::
|
|
|
|
### 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
|
|
|
|
With OpenCore Legacy Patcher v0.6.0+, basic support has been implemented via Root Volume patching. However due to this, users will need to use a USB hub for installation and post-OS updates when patches are cleaned:
|
|
|
|
|
|
|
|
::: warning The following systems rely on USB 1.1
|
|
|
|
* iMac10,x and older
|
|
* Macmini4,1 and older
|
|
* MacBook7,1 and older
|
|
* MacBookAir3,1 and older
|
|
* MacPro5,1 and older
|
|
* Xserve 3,1 and older
