Starting with macOS Sequoia, app downloads and installations from the Mac App Store will no longer require double the amount of local storage space available. Instead, the free space requirement now matches the final install size of the app, plus a small buffer, according to Apple.

The new space requirement in macOS 15 should significantly benefit users who download large games. Currently in macOS Sonoma, users have to ensure they have double the space available, which is often a challenge for games that can take up tens or even hundreds of gigabytes.

But in macOS 15 beta 2, you only need to have enough space for the game's final size, plus the small buffer, as per the release notes. By aligning the free space requirements more closely with actual app sizes, macOS 15 should give users a better idea ahead of time of whether they can install an app from the Mac App Store, which will make general storage management easier.

Apple has told developers to update any messaging related to app size requirements to reflect the change, which should reduce confusion about how much free space is needed for new app installations. macOS Sequoia is currently in its second developer beta, with a public beta expected in July, followed by a general release in the fall.

How is this supposed to actually work? I still have to download a dmg and then copy the app to applications which makes the free space I need 2 times the size of the app. Or did they actually use 3 times the size of the app and now it's just 2 times???

Also, free disk space is a joke on macOS these days because most "free" disk space is used for snapshots or whatnot.

To cut and paste on a Mac, select the item you want to move, press Command+C, then press Command+Option+V to move it to a new location. You can also access the move command in the Edit menu once you've copied a file by holding the Option key.

So how does this work exactly? If I am to install a system update, isn't it wise to keep the old installation before it can verify that the new one works correctly? Or are they doing something magical that they can still verify?

I had no idea about this macOS Quirk.
On the other hand, I never really installed tons of apps.

That notorious 256GB starting size of Apple is going to be bashed hard in this thread
Rightfully so! Especially when new Arm on Windows devices manages to use user upgradable storage that is faster than Apple’s implementation. I think the only benefit Apple has is some Battery life.

Hilarious. So to upgrade one 30GB game you needed 60GB extra space on your internal drive. Is that correct?
About right in some cases, yes.
It's not just the app store however, it's also installers you download from the web, because you need to store the installer package itself on your disk, then when it's extracted, you need additional space to store the app.

How much storage was required to go from beta 1 to beta 2? Genuine question: has Apple helped solve this problem in recent years to a meaningful degree?
