System Update 15.5.5 not installing and no error reported
So I have been prompted to install 15.5.5 on a Macbook Air. I press to install now. The computer asks about restarting and I say, "restart". The computer restarts, seems to install something but goes back to the state previously after login that says there is an update.
Round and round. Not sure if this thing wants to install.
MacBook Air 13″, macOS 10.15
