macOS 15 Installs No Longer Requires Double the Space for App Store

Apple is ensuring that macOS app downloads and installations from the Mac App Store no longer require double the available local free space on the storage system.

Starting with macOS 15, users are required only to have enough free space for the final install size of the app plus a small amount extra used as a buffer. According to the beta release notes, this all starts with macOS 15 beta 2. “Starting in macOS 15, the App Store no longer needs twice the space free for an initial app download and install,” the note reads.

Theoretically, this should help all macOS 15 users once publically available. Oftentimes, installs can reach upwards of 200GB depending on what the file is. Some file sizes reach inordinate amounts. Typically, this can be experienced when installing games. Reducing the required amount of free storage will undoubtedly help users as they don’t have to clear space to allocate free room for a new install. Moving forward, users should now have a better understanding of the storage demands of an app ahead of time.

Apple’s developer notes continue to state that developers should update any messaging related to app size requirements to reflect this change.

The macOS 15 beta 2 is expected to roll into a public beta next month. This version of macOS Sequoia should become available to the general user base by the fall.
