ggtopspin Posted March 28, 2017 Share Posted March 28, 2017 I have a Z270I GAMING PRO CARBON AC system and just updated to 10.12.4 after having a completely fine 10.12.3. When restarting, I immediately got this kernel panic. I narrowed it down to the clover FixHDA flag causing the kernel panic. Disabling the flag lets me boot just fine, but with the flag on it doesn't work. As a result, there is no audio. Has anyone else had this issue or has any idea how to fix it? Thanks!

ggtopspin Posted March 29, 2017 Author Share Posted March 29, 2017 I found my issue... the 200-series Kext patch was causing a kernel panic. For anyone else with this issue, this patch must be removed for 10.12.4.
