I've gotten almost everything working on my hackintosh but it seems that photos.app brings my system to its knees. The problem is that when I load photos.app, everything slows to a complete crawl. The mouse works but nothing else. I've done some searching and it seems that it's a problem unique to Sapphire RX 580 cards. There was some indication that it's due to HEVC. Whatever the cause, I've not been able to find a solution.

If I don't run photos.app, the computer is completely fine for hours. If I launch photos.app, it's essentially force reboot-land regardless of whether the computer's been running for 1 minute or 10 hours.

I'm running lilu.kext and whatevergreen.kext for graphics. iGPU is set to auto.
