Hello All and Thanks for your time... After down loading the itunes update my 2009 Mac Pro is acting strange,on start up the fans will go super high speed and both super drive trays will come open, this has only happened after this update. Has anyone had this same issue and how do you repair this problem. Is there a way to downgrade to the version before the update maybe? I'm new to Mac's so please be gentle, but so far wish I would have changed years ago, This is the 1st problem I have had since using Mac's. Got my 13 MBP in late 2009 now I have 2010 Mac Mini, 2009 Mac Pro 2.93 4 core, 27 ACD, and 30 ACD...32g ipod touch, soon to have iphone Verizon love them all....Thanks Again for your thoughts and time with this problem.... !!!!!!!!!!Found the problem!!!!! Not itunes!!!! USB keyboard dongle dosn't like to being plugged in on back of 27" ACD!!!! Found answer on Apple forum Thanks to everyone who viewed this post....So if you start having this problem just unplug all usb items and reboot then add back until problem shows up..........
