Error Making read-only compressed disk image containing Install macOS Big Sur.app #97

Closed sudyhardy closed 3 years ago

sudyhardy commented 3 years ago

installer: Package name is macOS Big Sur installer: Installing at base path /private/tmp/dmg.q5NMWM installer: The install was successful.

Working around a very dumb Apple bug in a package postinstall script that fails to correctly target the Install macOS.app when installed to a volume other than the current boot volume. Please file feedback with Apple!

Lots of things can cause hdiutil to fail to create a disk image. Sadly it's not giving us a useful error. But this works for me and others, so I'm inclined to think there's a local (to you) issue at play.
