murvold Posted August 7, 2015 Share Posted August 7, 2015 Running OSX 10.10.4 on a following setup: mobo: Gigabyte x79 up4 (rev1.0 latest bios version F7) cpu: i7 3820 gpu: Gigabyte Nvidia 970 mini itx 4gb (latest bios version F4) ram: 32gb (8*4gb) 1600MHz CL10 Kingston HyperX Fury hdd: 2*2tb WD Caviar Black + 4tb WD Black for storage ssd: Samsung Evo 850 Pro 256gb(windows) + Crucial M100 256gb(osx)[planning to switch soon for pcie ssd] bootloader: clover v2 r3253 bootflags: -v kext-dev-mode=1 pcirootuid=1 npci=0x2000 nvda-drv=1 nvidia web drivers: 346.02.02f03 Reboots when 2 or more displays are connected at startup. It reaches the end of verbose script and reboots. Once I was even able to type in my password at login screen, but usually it reboots just a millisecond before reaching the login screen so I'm not able to see the exact error message. I can attach other displays when fully booted and everything works just fine - Nvidia web drivers are successfully loaded and so far haven't noticed any flickering or other kind of distorsions. Anyone familiar with this kind of issue? I also added a bootlog from a successful boot via Clover Configurator, somewhy LogEveryBoot=Yes LogLocation=/Library/Logs/CloverEFI didn't produce any logs also clover automatically chose Mac Pro 4,1 SMBios if that makes any difference Thank you in advance Link to comment Share on other sites More sharing options...
le0nardwashingt0n Posted December 18, 2015 Share Posted December 18, 2015 how do you have your displays connected? I had a nvidia card that would cause a boot up kp if a DVI to VGA monitor was connected. Link to comment Share on other sites More sharing options...
bbeepp Posted December 19, 2015 Share Posted December 19, 2015 Change Smbios to iMac 14.2, The other solution is to boot with one display off. After you log in to desktop you can turn on the second display. Link to comment Share on other sites More sharing options...
