Question: Desktop items disappeared
After closing Safari I noticed that about 90% of my desktop items had disappeared. I found them in trash and moved them to the desktop.
Some Programs had also disappeared and I can not find them on my MacBook Pro. I also searched for them in my Time Machine but they are gone from there also.
What could cause this to happen. Where should I look to find the removed programs?
MacBook Pro (Retina, 13-inch,Early 2015), macOS High Sierra (10.13.3)
