You can wipe BIAB completely from your Mac. Then you’ll run the minimum installer from the 2025 drive to install the required support libraries. Now you’ll be able to run BIAB from your external drive.

Many are of the opinion that running from a USB 3 external is slower that having everything installed internally or an external SSD. Having tested all such combinations, I can assure you that the speed difference is there but it’s minor and doesn’t get in the way.

If you have purchased additional styles and packs, you can install them onto the external drive, manually or with the Install Manager depending on how long ago you purchased. These will be in your Purchase History..
