Once the file that reclaimed the purgeable space is deleted, the space goes back to being truly free, instead of purgeable again!

Purgeable space is freed when you ask the operating system to store a new file that exceeds the amount of true free space left on disk.įor example, if I have 15GB of space left on my disk, 5GB is truly “free” and 10GB is purgeable, If I create a file that is 6GB large, I will use up the rest of the “free” space and 1GB of purgeable. There are apps like cleanmymac3 which offer to clean purgeable space on your machine (for a fee) but I wanted to find a way to reclaim this space without the need for a paid service.

There has to be a way to reclaim purgeable space from the OS, right? How to Free Purgeable Space This prevented me from being able to pull in as many GB in to my Windows partition as I needed.Įven though I haven’t experienced it, I have also heard of folks running in to issues installing games or downloading large files onto their machines, and hitting the purgeable space wall. I had over 40GB of my hard drive confined to purgeable space, and even though that storage counts as “free” from an OSX perspective, it is still technically allocated. I ran in to issues with purgeable space when trying to partition my hard drive for a Windows installation. In my opinion, it’s a bit of a silly assumption on behalf of the OS to keep files around that the user is asking to send to remote storage. Presumably, you are sending files to the cloud to free up space on your local machine… if there is space available locally on disk, though, OSX will keep these files around in purgeable space which speeds up accessing the files again from your local machine. It is storage on your hard drive that the operating system sets aside for files that it thinks you might access again in the future.Īn example of files that are moved to purgeable space is files that you send to your remote iCloud storage. Purgeable Disk Space is a “feature” of more recent versions of OSX. Link to step by step instructions at the end of this post for reclaiming purgeable space on your mac.
