Congrats to John Siracusa on the release of his newest Mac app, Hyperspace:

There are plenty of Mac apps that will save disk space by finding duplicate files and then deleting the duplicates. Using APFS clones, my app could reclaim disk space without removing any files! As a digital pack rat, this appealed to me immensely.

It is a dangerously clever way to save disk space. I probably wouldn’t trust this app from anyone else, but I know John has tested the heck out of it. Your files are in good hands.
