Well on Friday morning I took the plunge and started to undo the misery of Tahoe.
Late on Saturday afternoon my Music library was back in a fully useable state.
If anyone is considering doing the same I’d urge you to google the process of downgrading the OS by a bootable USB procedure.
Make sure you do a Time Machine backup to a fresh USB drive. I used this as a reference for what to re-install after the OS was downgraded. It took a good 15 hours to complete but it would I knew it would help me identify what apps I needed to re-install and also that my data was safe.
Make sure you have an “old” version (one created under Sequoia) of your music library file as the ‘upgraded’ Tahoe version won’t work. They are usually in a folder called ‘Previous libraries’.
Export your playlists to files - I forgot to do this but thankfully mine haven’t changed much since the Tahoe.
I then wiped my Mac mini using the bootable USB stick downgrade procedure, remembering to log out of iCloud beforehand. My experience was slightly different to the video I watched but essentially it was quite straightforward apart from a point where the Mac went into some kind of authorisation / registration procedure which no video seemed to mention. I just entered the information it asked for and clicked through it and restarted the OS install in recovery mode, it all went well after that.
I had my Apple Music folder on a separate SSD - so its folders were untouched by the downgrade / wiping. I used the option key whilst opening the music app and pointed the library selection to the one just before I opted to ‘upgrade’ to Tahoe (from the previous libraries folder). All my music was visible again.
I needed to re-import the albums that were imported after the Tahoe ‘upgrade’. I had to make a copy of the album folders (that needed importing again) from the Apple Music folder to a ‘reimport’ folder then I deleted those folders from the original Apple music folder. I simply copied the albums back into Apple Music by dragging and dropping. If you don’t delete the existing album folders Apple Music with duplicate the files with (1) post fixes. You might also see that the album artwork gets stripped, so it’s a case of adding it back.
Don’t forget to reimport your playlists. I only had one playlist different and I simply added the songs back into it.
…. and that was it! I’m back using Apple Music on Sequoia and the iTunes remote app works perfectly!
Thanks Apple for your non testing worthless OS. Tahoe will never get re-installed.
