>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. I had this exact problem recently. There's a simpler, safer solution. Delete files to free up enough space. They're moved to "Reserved Space", and when the system fails to delete them to free up space for new installs/updates, you run sudo purge in the commandline. Wait 20m or so and the Reserved Space should be emptied and your hard drive free space again. http://osxdaily.com/2013/11/14/use-purge-command-os-x-mavericks/ http://osxdaily.com/2013/11/14/use-purge-command-os-x-maveri...
