  • My iMac is horrible! It constantly locks up and crashes. A few times an hour my Macbook will lock up with the spinning wheel of death for hours. A few times a day I will get a kernel panic. It keeps failing, and once it even wiped the hard disk! I reinstalled MacOS and it is still horrible. Not a nice choice, I have to admit.
