Uninstalling old Mac OS apps in my Macbook Air I have these 2 applications sitting in my Macbook Air Applications folder. I am currently running High Sierra and not planning to upgrade to either of these 2 versions. Is it OK to uninstall them or will their removal cause issues? Its currently taking up 11 GB and I want to free up some space.
It is perfectly safe to delete unwanted macOS Installers - simply drag them to the trash [&amp; empty it to recover the disk space], nothing further required.
You can always get them again if you need them.
Ordinarily, after a successful upgrade, the system would delete them itself.
