When I try to run the 704 update, I get this message
"Band-in-a-Box 2023 Build 704 Update Patch" can't be
installed on this disk. You can only install this software on
the disk that is running macOS.
I've tried closing the updater and trying again as well as rebooting.


The Installer app that installs packages occasionally does this for some reason that we do not know. The package is configured to allow installation to external volumes, and it appears to be some temporary issue / quirk. It is usually resolved after one of the following:
- restarting the installer. Or if that doesn't work:
- close other running applications
- If all else fails, rebooting the Mac should fix it.

Now, you say you've rebooted and it still doesn't let you change the location, which is unusual ... try closing other apps that are running - press Command+Tab to cycle through apps, and command+Q to quit them (except for Finder). After that run the installer. If you are still fighting with, the log file might have further info - could you zip and send us the /var/log/installer.log to support with a reference to this forum thread? Note - to toggle hidden files and folders in Finder, press command+shift+<period>
