macOS 10.14.5 Update

[unklemac]

Anyone managed to find the cause (and maybe a fix) for the purple lines upon boot for AMD GPUs? They're not a big issue, but they're kind of annoying. Same for the flashing screen. Now there's two issues with these cards and no one seems to have found a fix for any of them.

If your so annoyed with the purple lines during boot - I suggest you buy a real mac, or wait for later OS updates. It’s not gonna go away with a fix when everyone with AMD is experiencing it.

I got no flashing screen.

Just add 0x1005 to config.plist > CPU > Type.

This header file says that 0x1009 is more ideal value than 0x1005.

Update went almost perfect on good old 4790K setup after Clover update and USB Patch. No purple lines at boot with Radeon R9 380.

But my audio chipset is ALC1150 and I now have the same issue I had after updating to 10.14.4, no sound after wake from sleep, audio outputs disappear in preference panel. It might be the same for ALC1220 series.
Last time, it was resolved by an updated AppleALC kext, I hope someone more qualified will fix this.

For now, a script run by DSSW Power Manager after wake to reload AppleHDA is doing the trick, or in terminal:
kextunload /System/Library/Extensions/AppleHDA.kext
kextload /System/Library/Extensions/AppleHDA.kext

Updated went super smooth after updating clover first..
However, guys, I noticed that it took a little bit longer than when I had Sierra. It downloaded 3GB, and the install seemed like it was installing a new OS over the previous one..
Has Apple changed the combo update/app store update method? Did I miss something?
Good Luck to everyone..thanx

2 Issues that I have no found fix for on the Radeon VII.

1) DisplayPort audio crackling on monitor speakers (nothing fixes the issue, including SSDTs).
2) Purple lines everyone is experiencing.

As I said, it's not a big issue. Sorry if I sounded like a demanding a**hole. ) That was definitely not my intention. Just wanted to learn more about this issue. And I was hoping that, since this issue is now gonna come up more and more often (due to the latest official update, although it's been there since the Betas), maaaybe someone figured out a fix.

By the way, I do own a real Mac. And I don't have this issue. But obviously that's a different hardware. So, not sure what you're suggesting. But it's not really helping in this case, because I'm looking for a solution to this particular problem.

Also, about the flashing, so far, everyone with AMD cards (including Vega cards), had it. Could you, please, upload a video of your boot, from Clover GUI to login screen? I'm curious what could be the difference in your case.

No flashing or purple lines during boot with my old AMD R9 380.

Geekbench 4 OpenCL Score dropped from 200k to 144k on my Sapphire Nitro+ Vega 64

Anyone with similar issues?

Someone can test BruceX on the new release for performance drop?

BTW, same purple stripes here
