OS Tahoe & IOS26.0 Itunes / Music does not sync nor settings any longer accessible
Good day everyone.
MacBook Pro with Tahoe 26.0 & Iphone 15 Pro Max with IOS 26.0.
I still have ITunes (now Music) but do not want to get Apple Music subscription, as I have been using Itunes since its inauguration and have thousands of music tracks, movies and shows.
Prior to updating to Tahoe 26.0 and when I open Music on my MacBook, I could set the sncy settings i.e. which playlist and/or artist (especially newly purchased tracks) to transfer to my Iphone.
This now does not work any more.
The "SyncSettings" button top right corner on the Music application on my MacBook is not accessible anymore. My Iphone is shown within the Music app on the MacBook, and when I left/right click the symbol I can sync, but the playlists and artists are not sycnd in reality to my IPhone.
Today I created 2 more playlists and they also do not get sncyd. What is on my IPhone Music is only the Playlists and Artists which I have sncyd before I upgraded to Tahoe.
I re-booted both devices, de- and reauthorized devices, signed in and out of my Apple ID etc .... all to no avail. No further updates are available.
Can only assume this is a bug with the new Tahoe software, which does not recognize the "older Music" versions like Itunes sync settings .... I still want and need this, so would appreciate any one out there to be please check / provide guidance. Cheers and have a wonderful day.
