Much appreciated!! I am using a late 2012 iMac 21.5" 2.9 GHz Intel Core i5 8 GB 1600 MHz DDR3 ( Not up gradable Using a 250 GB External SSD Sandisk Using about 190 GB I run basic stuff Mac apps plus Spotify, AirFoil, VLC, Firefox, Safari, a VSP and maybe a few other things rarely all at once. Anyway when I first added the SSD it was like night and day but lately things have grinded to a halt way too often. I ran Malware Bites no issues there. I cant reallt think of anything I am doing differently except maybe using FF as my default browser. Can anyone recommend some steps? I want the Mac Mini oh so bad but have to save more cash first. Need to milk this puppy just a little longer. Thanks in advance!!
