Bonjour,
quelques nouvelles d'
OCLP et de
Sequoia:
Pour les impatients, voila un extrait d'un post d'OCLP 
:
"Comme chaque année, nous ne pouvons pas promettre quand le support sera ajouté. Cependant suite aux prévisions des années précédentes, nous espérons l'hiver 2024 avec
OpenCore Legacy Patcher v2.0.0. Le développement se déroule bien en interne et nous espérons que tout le monde est excité !"
Divers:
Ils ont déjà identifiés pas mal de problèmes et de patchs qui ne fonctionnent plus ou mal (il y en a pas mal ...).
Le post complet:
Another year, another WWDC and macOS version. This time with macOS 15, Sequoia, and a surprising lack of dropped hardware compared to previous years
As the OS has been in developer beta for a few weeks now, we've compiled a list of challenges the patcher will need to overcome for this fall. This list will likely expand as we determine more issues with older systems.
- Dropped Models
- T2 MacBook Air and OpenCorePkg Challenge
- Trackpad Support
- General patches needing updates:
- Graphics:
- Metal 31001
- Metal 3802
- Non-Metal
- Wireless
- T1 Chip
- USB 1.1
- Overall timeline for support
Dropped Models
One of the most tame OS releases since macOS Catalina, currently only 2 Macs were dropped:
MacBookAir8,1: MacBook Air (Retina, 13-inch, 2018)
MacBookAir8,2: MacBook Air (Retina, 13-inch, 2019)
T2 MacBook Air and OpenCorePkg Challenge
The current biggest issue we face with supporting the MacBookAir8,x (2018/19) series is the T2 chip's lack of communication when booted through OpenCorePkg.
What happens when one of these units boots through OpenCorePkg is that AppleKeyStore.kext panics due to timeouts with the T2 chip:
"AppleKeyStore":3212:0: sks timeout strike 18
"AppleKeyStore":3212:0: sks timeout strike 19
"AppleKeyStore":3212:0: sks timeout strike 20
panic(cpu 0 caller 0xffffff801cd12509): "AppleSEPManager panic for "AppleKeyStore": sks request timeout" @AppleSEPManagerIntel.cpp:809
This affects not only macOS Sequoia, but macOS Ventura and Sonoma are confirmed to have the same issue. Thus an underlying problem with the MacBookAir8,x's firmware where it is not happy with OpenCorePkg.
We currently do not have any leads on what exactly breaks the T2.
- MacBookPro15,2, MacBookPro16,2 and Macmini8,1 do not exhibit these issues in local testing
- MacPro7,1 does seem to surprisingly based on reports: MacPro7,1 - OpenCorePkg
Trackpad Support
Certain Force Touch Trackpads lost support in macOS Sequoia, namely those used by unsupported Macs. The primary issue is simply the loss of identifiers to match onto older hardware.
For most hardware, this has been resolved with the following commit:
General patches needing updates
The following patches have broken either partially or entirely. This will require additional work to properly identify issues and solutions:
- Graphics:
- Metal 31001
- Intel Broadwell and Skylake
- AMD legacy GCN, and modern GCN on non-AVX2.0
- Metal 3802
- Intel Ivy Bridge and Haswell
- Nvidia Kepler
- Non-Metal
- Intel Iron Lake and Sandy Bridge
- AMD TeraScale
- Nvidia Tesla and Web Drivers
- Wireless
- T1 Chip
- USB 1.1
Overall timeline for support
As with every year, we cannot promise when support with be added. However following previous years' predictions, we hope for winter 2024 with OpenCore Legacy Patcher v2.0.0.
Development has been going strong internally and we hope everyone's excited!
En résumé, patience
