What os does the R9 380x work better on Yosemite or el captian

[arvs21]

I have read the Radeon Compatibility Guide But still haven't found any answers for my power color 380x I know that el captain has some problems but in my research I have found that both el captain and Yosemite have problems so which one would be the better???

thank you,

Yosemite should be much better, because the power management issues (boot to black screen) don't exist there.

I have the same problem as you.
10.11 after automatic reboot, it boot to black screen.
I am downloading 10.10 now.
Hope it work
