I think my partner wiped our entire hard dive including backup utilities etc.
Whenever I start up my MacBook I get a “no entry” or “prohibited sign” (circle with line through it).
I’ve tried booting up in safe mode with the same response, I’ve tried running disk utility and that also does not work. I’ve tried resetting my ram with no difference.
So once I found out these results I tried re-installing via internet download but that produced a 6009f! Error (?).
I’ve tried bootable USB, however whenever I try to run it, it just restarts my computer leading me to the prohibited sign.
Any and all suggestions welcome. I don’t care about the data loss I just want my laptop back. How can I wipe and reinstall an OS?
