Ok, I’m in a bit of a pickle here. I wanted to install the latest macOS 10.15.1 update today and was initially told that I needed to “free up more space”, since the upgrade expects about 19 GB of free space. Ok, I did that and the upgrade installer launched (after a restart). Unfortunately, it told me (again) that I do not have enough free disk space and I was supposed to restart the machine to free up more space. Ok, I tried that but I am now stuck on the login screen. Every time I login the loading bar progresses to about 50% and the screen just turns black.
I went to the Apple store today and they mentioned I should just try to re-install macOS.
I can see the answers suggested here on how to accomplish that: Mac stuck in restart cycle after failed macOS Catalina update
However, when trying to recover / reinstall macOS - the installer also tells me - you don’t have enough free space to reinstall macOS.
So I am left wondering - why is there no option (e.g. in Disk Utility) to selectively free up some space. It seems the only options I have are: 1. create a full disk image (through Disk Utility) 2. Wipe the disk 3. re-install macOS
It would be great if I could somehow launch a terminal or something similar to free up some space. With the latest macOS, is there still a way to launch into “terminal login mode” - I believe this used to be possible.
Btw. I did try “safe boot” and all the rest without success.
Any help on how to free up just a bit of space so I can launch the macOS installer would be much appreciated!
