Instead of working hard, Apple chooses to work smart (for the most part, looking at you, G4 Cube). Instead of making your hard drive bigger, they’ve tackled the problem of limited space on your Mac with cloud storage. Which, in its turn, created a slice on your storage bar named “Purgeable”. Now let’s take a look at how did that come about.
Apple Mac OS X is generally good at memory management but I sometimes find the inactive memory takes a long time to be released as free memory and my system can grind to a bit of a halt if I need to start up a virtual machine. This post shows how to use the purge command to free up the inactive memory. To expand the file you will need PKZip for PC's or Stuffit for Mac's. Do not attempt to purge your print head by injecting water, alcohol or Windex or anything else directly into the print head. It can lead to problems if not done exactly right. The above purging procedure is the safest and most reliable purge method for the sponge filled.
Purgeable storage consists of files that macOS deems suitable for removal. Something that can be literally purged away from your drive and cause no trouble. The appearance of Purgeable storage is connected to the feature of Optimized storage in macOS. When Optimized storage is turned on, loads of files get moved into the cloud and for some of them, actual presence on your drive is optional. But for which exactly?
Nobody can be a hundred percent sure, but the main guess is that these are both your files and system-generated files that comply with two criteria:
Purgeable files can be of any type. From watched movies in your iTunes to applications languages you’ve never used.
But what renders them purgeable and what does it mean? The system finds these files and knows that when you start running out of space and you have your Optimized Storage turned on, it can remove these files to give you more space.
You can see how much space your macOS can purge in a number of places:
You don’t usually need to delete purgeable space on your own, but if it really bugs you, jump to the next headline. Purgeable space is labeled so that you know: whenever there’s a free-space issue, you’re safe because your macOS will automatically clear up that purgeable space and it will become free space instead.
The only thing you need to do to have your macOS removing these files when it’s needed is to have your Optimized Storage turned on. To do it, go to the Storage tab in About This Mac menu and click Manage. Now you can turn any option you’d like to be synced with iCloud. You can read more on Optimized Storage and how to use it.
Yup. It’s pretty easy and all you need is a Mac maintenance app like CleanMyMac X that does exactly what macOS does — detects useless files — but unlike macOS, lets you remove them quickly.
Now, to remove purgeable space in just a few clicks:
Once you’ve reclaimed purgeable space, use CleanMyMac’s Smart Scan tool to remove junk files, speed up the system and scan your Mac for malware — all in one go.
Also, it’s a good idea to clear your browser extensions, old Wi-Fi connections, and apps you don’t use once in a while. Simply in a form of general Mac system hygiene.
That’s about all you need to know about what is purgeable space on Mac, so we hope this article has been of help. macOS is a great addition to Mac, we’re glad it has space-saving features and other cool stuff (Siri!) but it could’ve been a bit clearer to users, that’s for sure. Anyway, have a good day and keep your Mac clean.
