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

Same problem here, Sequoia 15.3.1 with OCLP 2.2.3, I load no AVX/AVX2 kext in OCLP EFI, the system can boot fine, most 3rd apps can working fine, but App Store crash.

Same thing here.

On discord I found:

Using the mentioned command, I was able to start the app store.
Afterward I changed the setting back with:

launchctl setenv JSC_useJIT true; launchctl setenv __XPC_JSC_useJIT true

I did not notice performance issues while doing this, but it may be completely different with safari and other stuff.

Thanks for your sharing, I used the first comment to successful run App Store, that's great!

I'm not sure why my Sequoia installs do not have these problems. Just upgraded to 15.4.1 - app store and Safari still good. But it suddenly occurred to me - my CPUs are upgraded to X5680s. Perhaps X56xx CPUs are the difference between stability and weirdness.

None of my other upgrades (drives, SSDs, McFiver) are likely to affect app stability. Also, I tried Sequoia before getting the McFiver, so it cannot be the key.

Don't think it has anything to do with the CPU's. Mine are the 5690's and it crashes.

Xeon X5690 has no AVX and no AVX2 capabilities.

Xeon X5690 has no AVX and no AVX2 capabilities.

My reasoning was the OCLP devs may have used X56xx CPUs, and didn't check all Sequoia AVX patches against other CPUs. That would have explained my system's stability vs other peoples' issues.

Ouch. Well, another theory bites the dust.
