I'm proud

Моя проблема

iMac was slowed to a molasses pace starting with Mavericks and degrading with Yosemite to intolerable with el capitan

Моё решение

Took me about 5 hours with snl and infomercials playing through the wee hours but once done it worked like a charm without a hitch throughout the upgrade.

Мой совет

Perhaps one final reminder to put all the screws back in that hold the display attached to the stand BEFORE putting the glass covering back on.

My bad, but frustrating after such a long repair.
