Hi,
I have a 2009 4.1 -> 5.1 MacPro with a Samsung 840 SSD boot drive on a Apricorn Duo sled and several conventional HD's in the drive bays (see signature below for details). I've been running Cindori's Trim Enabler, but when I tried to upgrade to 10.10.2, my machine gets stuck in a boot loop. Prior to running the upgrade I turned off TRIM support, restored kext-signing, rebooted, and ran the upgrade. The Apple boot logo comes up on the monitor connected to a GT120 GPU, but when the progress bar gets about 1/3 of the way across, the mac shuts down and reboots, stuck in a boot loop. Prior to trying the upgrade I cloned my boot partition on the SSD onto a backup partition on a conventional drive, so I'm able to boot from my backup drive and then use CCC to restore my SSD drive to 10.10.1.
If I try the reverse sequence, changing the startup boot drive to the HD, booting from the HD, and then running the 10.10.2 updater, again I get a boot loop. I can hold down the option key during the boot loop to force a reboot from my SSD and recover, but still in 10.10.1.
Just to be sure I don't have a problem with kext-signing, I ran this command from Terminal: "nvram boot-args". It returns the result "boot-args nvda_drv=1", because I'm running the Nvidia web driver with my GTX 970.
I'd like to be able to upgrade to 10.10.2, but something is interfering. I've tried invoking the upgrade from AppStore and from the 10.10.2 Combined Upgrade, with the same boot loops. Any suggestions? Thanks in advance.
