My buddy and I have two identical iMac 2011 27" i7 with the 2GB graphiccard and SSD. The problem is that my iMac are extremely slow in the bootup phase compared to my buddys. His POSTs and bootup is done within a 1min where mine takes atleast 4-5min. The first grey screen - where there are no loading circle or other icons are is where it really stalls - this part takes atleast 4min where his machine takes about 10secs to do the POST. I have tried searching for a firmware restoration for 12,2, but with no luck I have reset the PRAM several times with no change. The other weird thing is that on my buddies machine it shows the external firewire drive as a possible drive to boot from, but on my machine it doesn't. I have a totally fresh installation of Lion 10.7.2 and it's 100% updated with the newest firmware and software updates. I would greatly appreciate any ideas to solve my problem. It's very annoying as I often have to reboot to bootcamp Windows 7, which should take 2min but takes the better part of 5-6min. When the machine is actually booted up it just as fast as my buddy's machine. The only difference is that I by mistake ran Trim Enabler on 10.6.8 to enable trim service. This gave me alot of beachballs, so I reverted back to the original settings/drivers.
