Did you try the beta drivers?

Did you try the beta drivers?

If the question for me !!
No I did not ; I am still on 10.14.4

You think it will fix my issue ?

Try replacing the driver files and see if it helps for your issue: https://www.tonymacx86.com/threads/...fans-ramp-up-down-rapidly.275228/post-1942003

Tried it and lost the ability to arrange displays. I am forced in mirror mode and cannot adjust resolution.
This is on an RX580 on 10.14.4.

Proceed with caution

Use new drivers from 10.14.5 beta: http://www.mediafire.com/file/j93hkbk551ajvaj/Archiv.zip/file
Just copy them to S/L/E and replace. Refresh kext cache, repair access rights, reboot, enjoy.

Well, fan bug solved by copying the kexts and bundles... but purple lines now on the bootscreen before the usual white flash... RX560 here.

Could you post the output of this command in your system?

ioreg -l |grep \"PerformanceStatistics\" | cut -d '{' -f 2 | tr '|' ',' | tr -d '}' | tr ',' '\n'|grep 'Temp\|Fan\|Power\|Clock\|Utilization'

Purple lines are just an optical flaw and not an issue. It happens on Vega cards as well on 10.14.5 B2.

Well, thanks, good to know that I'm not alone. Just weird that it wasn't there on previous Mojave versions. I've tried a clone of 10.14.4 updated to 10.14.5 beta 2 this morning: Purple lines appears for RX560 and RX580.

However, the fan bug looks to be solved.

That's because it is beta. It isn't guaranteed to be perfect.

Yes, however as real MacPros don't have bootscreen at all, less chances that it will be reported...
