I disabled macOS Sierra storage optimizations and the Storage tab in About this Mac still shows over 70 GB as purgeable space. Is there a utility to display which files are considered as purgeable?

    Although it doesn't answer the question, connecting to your backup drive(s) may help to resolve this issue. support.apple.com/en-ca/HT204015 See also my answer to my own related question apple.stackexchange.com/a/361011/80135 My experience suggests that you have to back up to all of the drives that Time Machine knows about before it clears out local snapshots.

    Again not answering the question. I would use Disk Inventory X to get a better idea of where you should focus your attention. derlien.com I would look at IOS updates and not needed backups as they tend to take up quite a bit of space usually. Jun 23, 2019 at 0:41

Two utilities that show and optimise purgable space are DaisyDisk and CleanMyMac X. My experience is that these utilities will clear 20-30% of the space that it reports as purgable.
