Apple of 2019 is the Linux of 2000

Last week the laptop I use for macOS development said that there is an XCode update available. I tried to install it but it said that there is not enough free space available to run the installer. So I deleted a bunch of files and tried again. Still the same complaint. Then I deleted some unused VM images. Those would free a few dozen gigabytes, so it should make things work. I even emptied the trash can to make sure nothing lingered around. But even this did not help, I still got the same complaint. At this point it was time to get serious and launch the terminal. And, true enough, according to df the disk had only 8 gigabytes of free space even though I had just deleted over 40 gigabytes of files from it (using rm, not the GUI, so things really should have been gone). A lot of googling and poking later I discovered that all the deleted files had gone to "reserved space" on the file system. There was no way to access those files or delete them. According to documentation the operating system would delete those files "on demand as more space is needed". This was not very comforting because the system most definitely was not doing that and you'd think that Apple's own software would get this right. After a ton more googling I managed to find a chat buried somewhere deep in Reddit which listed the magical indentation that purges reserved space. It consisted of running tmutil from the command line and giving it a bunch of command line arguments that did not seem to make sense or have any correlation to the thing that I wanted to do. But it did work and eventually I got XCode updated. After my blood pressure dropped to healthier levels I got the strangest feeling of déjà vu. This felt exactly like using Linux in the early 2000s. Things break at random for reasons you can't understand and the only way to fix it is to find terminal commands from discussion forums, type them in and hope for the best. Then it hit me. Read more
