I've been having some nasty beachballing that will then lead to nothing responding and then I have to force power down the computer. I still haven't found the root of those issues because nothing actually crashes so I can't find anything in the crash logs. I seem to have maybe fixed that issue with many different troubleshooting attempts, but my issue now is why my whole entire Macintosh HD partition is labelled as "Other" in Disk Utility and under Storage in About This Mac. I tried First Aid and repairing permissions, but it doesn't say there are any issues. Hardware testing also comes back clean. I know I have little space left currently, but I had to make a second backup while trying to troubleshoot the annoying "Last backup could not be completed" bug for my iPhone 6S. Anyone know how to fix this "Other" issue? I looked around and found people with problems with a large amount of space being taken up by the "Other" files, but didn't find anyone whose entire drive contents were marked as such.
