Error while reinstalling Sierra
Hey!
Ran Mac OS Sierra and then I tried to update to Big Sur:
Got stuck with that error, so I erased my hd (with the disk utility). And tried to reinstall Mac OS X.
If i press cmd + R the installer gives me the following error:
“The Installer information on the recovery server is damaged.”
If i try other boot options (cmd+shift/alt+R) the installer wont start, it just gives me à black screen with an Apple url and -1007F.
The mac is a mbp 2017 13”.
Any ideas?
MacBook Pro 13″, macOS 10.12
