*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 v1.0.0, early support for macOS Sonoma has been implemented. | ||
|
||
## Versioning | ||
|
||
With v1.0.0, 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 v1.0.0 will support Sonoma for all models normally supported by the Patcher, however some challenges remain. You can find information about them below. | ||
|
||
## Issues | ||
|
||
* [T1 Security chip](t1-security-chip) | ||
* [USB 1.1 (OHCI/UHCI) Support](#usb-11-ohciuhci-support) | ||
* [Graphics support and issues](#graphics-support-and-issues) | ||
|
||
|
||
### 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 ATTENTION: Additionally, due to Sonoma no longer caring about T1, erasing the entire drive will remove the T1 firmware and it won't be reinstalled. | ||
::: | ||
No known solution to resolve supporting, a significant amount of time will be required to understand how both the T1 stack works, as well as where the core issue lies for support. | ||

|
||
### 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 | ||
* Macmini3,1 and older | ||
* MacBook7,1 and older | ||
* MacBookAir3,1 and older | ||
* MacPro5,1 and older | ||
* Xserve 3,1 and older | ||
