MacBook Pro 13,3 2016 15” has had issues in every version of Sequoia & OCLP. They started with crashes of identityservicesd which made Messages.app not work. As I forged ahead with Beta updates & nightly OCLP, things got better & worse. Early in macOS 15.2 beta the crashing of identityservicesd ended, and Messages.app started working again. Unfortunately this coincided with coreauthd crashes, which meant App Store didn’t work, Chrome & Brave browsers stopped responding as soon as they checked for an update, and log-in became problematic. A lot of Safe Boots, and trying to sign-in to App Store, or change log-in settings was very frustrating. It had been many many weeks since ‘upgrading’ fully functional Sonoma to this always broken Sequoia, I made a Sonoma 14.7.1 installer USB to downgrade back to Sonoma. However, today there was 15.2 Beta 4 (24C5089c), so I gave it one last shot, using OCLP 2.2.0 Nightly. It was difficult to get Software Update to offer the update to Beta 4. I changed setting back to normal, then to beta, several times. Often it wouldn’t even check, just saying I was “up to date”. I rebooted into Safe Boot and tried, nothing, then back to normal, but quickly as possible to Software Update, finally it offered up 15.2 beta 4. The download and upgrade were uneventful. OCLP intervened to download the Beta 4 KDK simultaneously. I was surprised the KDK seemed about 200mb larger than previous KDKs. Restart was normal, but without the OCLP post-install root patches, the display was flashing & glitchy, no WiFi, etc. I didn’t wait for OCLP to automatically launch, I launched it immediately. Root patches were normal, upon reboot, EVERYTHING WORKS!!! Console>Crash logs have nothing (they were FULL of identityservicesd & coreauthd crashes. Seems this issue likely limited to Macs with T1 chip? So happy, it’s been a LONG time to finally get a fully functional Sequoia.
