MP 1,1-5,1 OpenCore Legacy Patcher (2.2.0) on Mac Pro 5,1: Issue with Safari and App Store after upgrading on macOS 15.2

[marisgly]

Hello, I’m using my Mac Pro 5,1 with OpenCore Legacy Patcher 2.2.0 and just upgraded from macOS 15.1.1 to macOS 15.2. Before I’ve already had a problem with Apple Music crashing when searching for music or artists. Now after the last update I’ve also got following issues: When I try to open the App Store it crashes immediately. And when I want to open a website on Safari, it won’t load and only shows „An error occurred with (e.g. „https://www.youtube.com“)“. Can anybody help me with a solution?
Attached is the error report of the App Store Crash.

EXC_BAD_INSTRUCTION (SIGILL) happens when an invalid CPU instruction interrupted the process, this is most probably an AVX/AVX2 instruction inside JetEngine.JSStack.scheduler. Since MacPro5,1 Xeons do not have AVX/AVX2 support, the thread crashes.

If Apple started to require AVX/AVX2 support even with JavaScriptCore, things are becoming pretty complicated. The only thing that you can do is to report it to OCLP, maybe they can workaround it someway.

I can report the same result. About to downgrade to 15.1.1.

Have you upgraded your root patch with the new version OCLP 2.2.0? It tries to mitigate these issues.

Yes. Root patches were upgraded as well. Also reverted and reinstalled patches. Also reinstalled 15.2 an additional time. No luck, unfortunately.

Same here. Appstore crashes with the same error and Safari won't work.
2.2.0 clearly does not work with 15.2 on my MP5.1

For further reference: 2.2.0 Is currently working for me on 15.1.1 after a restore.

Same here, 15.1.1 works.
15.2 even froze when using Chrome.
MacPro 4,1 / 5,1
AMD Radeon RX Vega 64

64GB Ram (2*32GB with CustomMemory)
btw.: No WiFi card installed. So I assume that the "modern wireless" AVX patching might be skipped.

I found that on 15.2 beta 1, 2 and 3, Safari and App store worked fine.

It was only with beta 4 , RC , and final release did the errors occur.

I used OCLP 2.2.0 to work around the Safari issue on one 5.1 but I haven't been able to dedicate much time to the other "test" Mac Pro that updated to 15.2.

The daily driver Mac Pros stay on Monterey!
