This should come in handy, or at least alleviate a minor headache when installing the macOS or applications.
Apple on Tuesday announced that beginning 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.
As of now, within macOS Sonoma, users have to ensure they have double the required space for an installation. This can result in having to clear space for tens to hundreds of gigabytes of data prior to the installation, which can be its own headache.
As of macOS 15 beta 2, users only need enough space for the installation’s final size, plus a small buffer. 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 their software relating to app size requirements, which should help reduce confusion as to how much space should be available for 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.
Stay tuned for additional details as they become available.
