Can I delete it? Why is it still there? I already created a feedback for this in June but got no response.
macOS 11 beta created an Update partition that is still there after installing the official release
I think it's extremely sad that nobody at Apple wants to help me out here. Is it intended that we install official things that leave garbage around and not even the developers are keen to point out what it is, or to show that they even care about what happens to our machines after installing their software? (Yes, I submitted a bug report 1.5 years ago, in June 2020, obviously without response.)
You contacted Apple support as well I guess ?
