Hello, I just started noticing how long my iMac takes to boot. When I press the power button I hear the "dong" sound and I get a white screen for 30 long seconds until I finally see the Apple logo and a couple of seconds later the progress bar from Yosemite. My computer wasn't this slow to boot. I have a fusion drive which should make it faster to boot. I mean, it used to boot in minutes. Has anybody experienced the same with Yosemite? I cleared my caches folders and repaired permissions. I did fsck -f from single user mode but everything's still the same.
