I was trying to solve an issue with memory disappearing to 0kb, and after reading some post here I have :
delete some files from cache folder(library)straight to rubbish bin
An deleted some core files applying this in the terminal:
cd /cores; sudo find . -mtime +30 -type f -delete
I've stopped bot process as something was not right (some items where changing the logo as programs for example) MyMac has restarted to the folder with interrogation. I ve tried to find solution but nothing. Neither command+r neither alt key where working. alt(option) just show a mouse in the screen.
If there is something I can do ? Still don’t understand why it happened as I understand here it was safe to do it. Is there a solution not loosing the info?
