Good news for those buying a Mac with a small internal disk! from macOS 15.1 Sequoia From then on, App Store apps can be installed and used directly on external disks connected to your Mac. In other words, apps are no longer forced to be installed on the main storage drive, but these apps can not only be downloaded externally disk, and can also be downloaded to an external disk.
This new feature is especially useful for Macs with small primary storage drives, allowing you to save internal disk space for more space.

Another “limitation” may be boot speed (external disks are generally slower than internal storage units) and the need to use disks initialized as APFS andUnable to instantly select where to download the app (After selection, the destination remains the same, if you want to change the destination on the fly, you need to go to Settings again).
Obviously the external drive we choose must be connected to the Mac; the application downloaded to the external disk will appear in the Applications folder and can be opened as usual with a double click and used like all other applications (in any case It will not appear in Launchpad next time).
Obviously we recommend that you choose disk (preferably SSD) The fastest external connection speed For a buying guide, we recommend checking out this article of ours.
