foster Posted August 3, 2015 Share Posted August 3, 2015 El Capitan DP Beta 5 Yosemite 10.10.4 Clover 3252 System Protection disabled. If I only boot into El Capitan (restart) everything is fine Problem happens after restarting into Yosemite then restarting back into El Capitan Example: start system into El Capitan restart and boot Yosemite restart and boot El Capitan - I get a kernel panic during startup - rebuilding caches fixes issue.

D-an-W Posted August 3, 2015 Share Posted August 3, 2015 I'm no expert ( ) but could it be due to something in your NVRAM, assuming you use it of course? Link to comment Share on other sites More sharing options...
foster Posted August 3, 2015 Author Share Posted August 3, 2015 I use actual nvram since my board supports nvram and no emulation. I decided to delete all the efi-apple-payload variables using nvram -d efi-apple-payload...... for each listed variable Also found I had a duplicate copy of AppleHDA,kext, same kext in /S/L/E and /L/E so eliminated the one in /L/E which was contributing to a KP if I rebuilt caches from terminal (not single user mode) Solved the problem Link to comment Share on other sites More sharing options...
