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.
What is Purgeable disk space on Mac?
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?
Jan 09, 2020 You can run Mojave and Catalina on the same Mac in a dual boot setup and without reformatting or repartitioning your Mac’s storage thanks to APFS, the file formatting system that Apple made ubiquitous with Mojave’s release. Great if you need to use apps that won’t run on Catalina, but still want to use what Catalina has to offer. Then you will have to verify that you have enough available space on your hard drive. To install macOS Catalina you will need at least 12.5 Gb free, and 18.5 Gb if you will update a Mac that still uses OS X Yosemite or some previous OS. Checking if you have the necessary memory is very similar to checking the model of your Mac.
The storage tab in 'About this Mac' showed 9GB of free space and 165GB of 'other'. Pretty weird. I investigated and found that Catalina appears to create its own APFS Volume for user data, so there are now 2 macOS Volumes, one for system (which is about 10GB in my case) and one for user data (which is 230GB).

MacBook models that are 2015 or later will also be able to update to macOS Catalina. Here are the Mac models on which you can install macOS Catalina. Source: Apple. Not enough storage available: your Mac does not have enough space to download and install a new version of macOS. To upgrade to macOS Catalina, there is at least 12.5GB of storage space in your Mac. There's something wrong with the disk on your Macbook.
Which files are considered Purgeable?
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.
How do I view my Purgeable Storage?
You can see how much space your macOS can purge in a number of places:
How to clear Purgeable space on Mac?
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.
Is there a way to force remove Purgeable space on Mac?
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.

Announced in June 2019 at WWDC, the long-awaited macOS Catalina will be the 16th major release for Apple's operating system. There are tons of new features to be shipped, covering everything from iPad compatibility (Catalyst makes it easy to port iPad apps to Mac) to security (Gatekeeper will require Apple-notarized Developer ID for apps) to entertainment (new apps for Podcasts, TV, and Music), besides the usual improvements to all the native software.
While macOS Catalina is scheduled to be released sometime around September, the public beta is already available, so everyone can try all the new functionality without the wait. Read through our step-by-step guide to learn how to install macOS Catalina public beta.
Is My Mac Compatible With macOS Catalina?
Regardless of whether you want to install the beta or wait for the official public release, one question will inevitably pop up in your head — is my Mac compatible with macOS Catalina? Good question! Let’s look at the Mac OS Catalina compatibility chart to find out.
List of macOS Catalina supported Macs
Overall, due to the numerous efficiency improvements under the hood, macOS Catalina supported Macs are nearly identical to those of macOS Mojave:
The only difference you might find is the new Mac OS Catalina requirements not covering Mac Pros ranging from 2010 to 2012. So unless you have that specific Mac Pro model you should be able to try the new operating system.

However, in case your Mac is on the older side, barely managing to load the macOS won’t result in a pleasant experience. For example, Apple specifies that running 4K as well as Dolby Atmos content will only be possible with Macs introduced in 2018 or later that boast 4K screens.
But don’t hurry to the Apple Store just yet. If watching videos in 4K is not an absolute necessity, you could simply optimize the Mac you have for faster performance and run macOS Catalina without a problem.
What are macOS Catalina storage requirements?Available Space For Mac Catalina Bay
To run properly, macOS Catalina needs a considerable amount of disk space. It’s generally recommended to keep at least 15% of your main drive free. But remember, you’ll also need space for future macOS updates and all the new software that goes with Catalina. So you should think of freeing up storage way beforehand, while you’re still on Mojave or other older OS.
The general space goals to aim for here:
Upgrade smoothly: remove outdated system files
The best way to rise above the basic Mac OS Catalina requirements is to do a thorough scan of your Mac and purge all the useless data that you’ve accumulated over the years. Quite a hefty task if you choose to do it manually: your Mac has a ton of system files and invisible folders that require the use of Terminal to get to. Luckily, there's a software designed to take care of it all automatically.
CleanMyMac X is the easiest and the most thorough way to bring your Mac back to its pristine original state. In fact, the app is so helpful and intuitive that it was recognized as the “#1 Product of the Month” by Product Hunt.
Here are the kind of files you should try to get rid of:

To do so with CleanMyMac X, simply:
Even though I’ve been using CleanMyMac X on a regular basis, the System Junk scan has revealed over 11 GB of files I no longer need. Imagine how much dead weight your Mac can carry!
Maximize your storage space
Once you clean your Mac from all the system and user-generated junk, you’ll notice improvements in responsiveness and speed right away. But it’s not only outdated files that slow your Mac down.
To hit all macOS Catalina system requirements, you need to have as much of your hard drive free as possible. This might include, for example, legitimate but long-forgotten documents you haven’t opened in years.

The good news is you can see what’s taking up your hard drive capacity with a new feature in CleanMyMac X called Space Lens, which creates an interactive visual map of all your files and folders:

With no extra system files or unused heavy folders dragging you down, your older Mac will become brand new again, agile enough to take on the new macOS Catalina as it becomes available this fall. Best of all, just one app — CleanMyMac X — can do it all for you.
