I just tried upgrading from MC22 to MC24. I have two Macs, one is the host to my library (call this Mac JRHost), and the upgrade went fine there. Everything is as it was. However the second Mac (call it JRSlave) doesn't really have its own library, but instead just loads the library from JRHost. When I upgraded the JRSlave Mac, all of its preferences and configuration were lost. It comes up as a bare-bones, fresh-from-factory MC. I tried to go back to MC22 and export the library config from there, but you can't export a library that's loaded from the network.

How do I restore JRSlave's MC24 so that it gets all of the preferences (audio setup, UI, etc.) from its MC22 incarnation?

I figured out that settings are only saved and restored as part of library backup and restore. This doesn't make sense to me, because my audio output settings don't really have anything to do with which library of music I have loaded.

But to make this work I had to do this on the "MCSlave" Mac:

-- run MC22. This loads the settings (audio, etc.) I always use.
-- load default (empty) library.
-- Backup the empty library.
-- Quit MC22. Launch MC24. At this point the settings are factory default.
-- Restore the empty library. This loads the old MC22-based settings I want.
-- Load the remote library.

That seems needlessly complicated, but it did the trick.
