I realized I have quite hefty 13GB taken up by my 2018 and 2019 texlive versions and wanted a clean reinstall and a lightweight latex environment anyway. I read I can simply remove the folders under usr/local/texlive/XXXX year. I 'rm -rf' the 2018 folder without issues but got a spam of access denials when attempting the same for the 2019 folder.
Using an app (DaisyDisk - monitors storage on my mac) it warns me to delete it as "2019 is required by macOS and should not be removed". Is there any issue maybe from installing, can I just 'sudo rm -rf' it?
I am now uncertain if I should do that or if I can break something with that. If somebody can reassure me or explain me what I am dealing with that would be great.
Thanks already for your help everybody.
