ALİ SADIK ŞANLI Posted January 29, 2023 Share Posted January 29, 2023 I need to do graphics acceleration patch with opencore legacy patcher for rx 580 and I have to use AMFIExemption.kext to do that. When I use this kext, I cannot run applications such as Whatsapp Steam Twitter Telegram, does anyone have a suggestion for this ?

Avery B Posted January 29, 2023 Share Posted January 29, 2023 (edited) The Polaris drivers in Ventura require AVX2.0 now, so OCLP is needed to revert back an older version that doesn't require AVX2.0 on older systems. Notice that they are using an Ivy Bridge CPU without AVX2.0 support (i5 3340).

MacNB Posted January 29, 2023 Share Posted January 29, 2023 Additionally on Polaris, AMD's Encoder/Decoder are broken caused by AMDRadeonVADriver.bundle and AMDRadeonVADriver2.bundle extraction on Ventura.
