So far I have managed to keep a 100% failure rate on all my apple computers. I bought a refurb mac mini, and imessage didn't want to retain it's settings. So after 2-3 hours of testing, they concluded that I should just wipe it and start again. 3 months later, that mini started to get panic crashes. Again, only solution was to wipe and reload This week, that same mini has now decided that it simply won't wake from sleep mode cleanly. Refused the wipe and reload solution and insisted that it goes in to be repaired before the waranty runs out. Sorry, 3 strikes and it's hardware Bought a new factory iMac 5K in start of Jan.. out the box, the screen kept on blanking and had to hit the power button to wake it. Ship it back DOA Got a replacement unit last week. Now imessage will not work. it's convinced that I am offline and won't let me change it. I've actually had better luck with my $300 HP windows laptop in keeping it running. So much for the saying that apple charges a premium becuase you get a premium product that just works. So far it looks like all i got was CRAP.
