MacBook Pro / OSX 11.7. , Big Sur freshly installed.
I proceeded as described in read me. The error message appears
"Installer.app is corrupted and cannot be opened. It is recommended to eject the image."
Gatekeeper disabled
Installer cannot be opened, this happens with all installers
Terminal input xattr -cr(space), then drag into terminal.
No effect.
Does anyone have an idea how to continue?
