and very happy now. No more frustration. Very solid computer. Takes a bit to get used to how Mac does things but not hard at all. Downloaded a few programs & installed easily. Had a secondary unwanted program sneak in undetected which fowled things up but was easily removed & back to rock solid condition. Big issue was transferring window based Quickbooks & wireless Canon all-in-one to Mac. Downloaded couple drivers & both started working even thought I didn't know what I was doing. Gotta love that. To hell with windows.Update 3/12/20-  IMac still working perfectly. Bought new IPhone to go with it as I'm tired of Android communication issues with my vehicle infotainment system. Communication was hit-&-miss.Plugged in my new IPhone...everything works as expected & without complicated issues as windows gave me.I've had a windows PC since they were sold to private people back in the 90's.Mac is the way to go now. Little bit different, but same.Wish I had done this years ago.Fed up with windows 10 upgrades. Not going to take it any more! (Twisted Sister pun)
