My mac pro is by far the WORST computer I have ever had. Let me list the problems i have had every day since i bought it: 1) Random blue screens (lite blue, like at log in) 2) DVD Drive works every other boot up 3) USB PORTS work sometimes, other times dont work at all 4) random hard drive unmounts 5) graphic errors ALL THE TIME 6) Random crashes 7) hard drives telling me they have 0 files, when I plug them into my iMac they magically have 200+ files 8) imovie crashes ALL THE TIME 9) final cut crashes ALL THE TIME 10) air port card works some times. APPLE is yet to fix ANY of these problems, and they refuse to replace my computer. WTF! Im at my wits end with this p.o.s. BTW apple: Im sick of hearing; reset the pram, oh that didn't work, try repairing disk permissions, oh that didn't work.... hum.... i will be back.... (10 minutes pass) .... um run a hardware test.... oh no results... we will have to get back to you...... BS I want my $4000 mac pro fixed! Is that so much to ask? COME ON!
