My ElCap update failed. I was able to get it back up with cmd-R. But ...


The MacBook Pro (late 2011) kept crashing, freezing, screen going black, sometimes blue. I restarted in recovery mode, did disk First Aid, and reinstalled OS.


Was good until I opened iTunes which would not load. Then I updated iTunes, but crashes began again.


It would only boot (or enter recovery mode) every 4th try but after a few weeks it was down to every 20th try.


FInally, I made a boot USB, backed up my files, wiped the drive (aftermarket Crucial 500gb SSD), then did a fresh install. It worked great until it didn't.


I tried to install the update and once again it got stuck. I once again reinstalled from USB (Seems as though clean install doesn't reinstall recovery boot sector). Everything was hunky dory and I spent 2 days reinstalling files, music library, and my extensive collection of instructional videos. Everything was perfect until ...


I tried to synch my iPhone 6 with iTunes open and it opened Photos automatically and the screen froze. I did a hard reboot and now it goes past the Apple logo to a blank screen. A band of colored noise briefly flashes across the screen, screen goes black, then to the white screen I call the Apple Desert.


Now it will not boot at all. No key combinations will resurrect it. NVRAM and SMC reset but still no boot. Will not boot into recovery mode. It will show the USB boot drive using Option but will not boot (BTW, it you try to do this and get the null sign you need a internet connection).


I was able to get it to load hardware diagnostics from the web (Option-D) and ran the extensive test but found nothing.


It could be I'm short of space so I ordered a 1TB drive. I'm hopeful I can do another clean install. But then what? I no longer trust the updates or iTunes.
