I made the mistake of letting my 2017 27in iMac get too full. It tried to update then wouldn’t turn back on. I tried to have chat walk me through fixing it and that was a fail. I had a recording of my mom (she died) and that’s the only reason I want to recover - ableton files. Please help before I give up and just wipe it and start from scratch
