you can run different OS's on Mac.. I think it requires a total wipe of your hard drive, tho, if I read correctly.. Right now everything is good.. I may upgrade to sierra before I save a bunch of files and have to re-backup..
I actually DID drink some last night and the night before.. If you'll remember I gave up drinking because it aggravates my neck condition.. But in high school I used to drink this German stuff called Kirsche Wasser with grenadine and 7Up.. So, I made a few of those the last two nights with a splash of lime.. Tastes like a Sonic Cherry Limeade with a little bit of a kick..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
