Hi everybody, big problems here: I had to hard reset my MacBook 12" (Sierra 10.12.3) after it didn't wake up. Now I can't open any program anymore – I always get the error message "You can't open the program XXX because it probably is damaged or incomplete" (roughly translated to English, I don't know the exact English phrase). When logging in as a guest instead, I can open the programs. I did boot into recovery modus and "first aid" on Macintosh HD – it didn't help. There's no dedicated "repair permissions" option anymore with Sierra. I don't know what else I could try at this moment Does anybody have a hint or do I really have to do a full clean reinstall? Thanks so much in advance for your help, highly appreciated!
