Repeat until you have the definitive answer. You could get the definitive answer by freeing a small amount of disk space. The definite answer varies from system to system. There's really no easy way to produce a definite answer for you. If you have 'Store in iCloud' set up, you need to give it time to work, whilst you do this. You need to either manually shrink local Time Machine backups, or incrementally fill the drive with junk data then erase it. Purgeable data will not just get out of the way if you need the space all in one go. That is the amount of actual free space you have, including purgeable. If your drive is so full that you are struggling to squeeze something on - which in itself is not a good thing, you really need to keep 10 - 20% free space, ironically more for a smaller drive - then the figure you need to be looking at is the one in Disk Utility, under the blue bar.
