Got a 2012 Macbook Pro. Was running GIMP with a couple Browsers open and Word. Gimp crashed twice and I had to restart it. I saved a GIMP file to a png. Placing one png over another, it all froze: Cursor and all not moving. Pressed Cntrl/alt/shift, etc and it closed the the first application open, in layered fashion, but until I got to the last finder window, it kept opening. Shut down completely. Start up took about 2 minutes (usually 37 seconds. Has 2TB SSD and 10GB memory). Was super fast, until today).
When I click on any file or program, it hesitates for a second, then opens as if it’s on a delay, with an odd trace of lighting or movement tracks. Tried the finder “search” and it isnt’ recognizing anything, like it’s not accessing directories, etc. Had to open Applications, to get DiskUtility and run it. Nothing changed. There is a thin grey line that appears to run horizontally through the middle of the “search box”. What’s up???
