iPhone 15 Pro shows "not enough storage" error when syncing music

I have an iPhone 15 Pro with 512GB storage, I am using 302GB of that now. I am trying to sync my music to the phone from my iMac but I keep getting the error that there is not enough storage space left and I need to free up 4.5GB, yet there is 209.28GB still available. I have tried restarts but still no luck.

Is the Mac storage-constrained?


I’ve met a few corruptions that were resolved by un-checking music (or photos) sync and issuing a Finder sync, which erases what’s on the phone, wait a few, forced iPhone restart, and then re-enabling the sync and then the Finder sync.


I’ve met this with both music and photos, though less common with music since using Apple Music and its sync.

If it is not the restart you tried, try a forced restart, holding the third button press until you see the Apple logo, continuing to hold the button press past any sliders.

Thanks, that is the restart that I have been using, several times, but it still won't sync.

It has 2TB of storage with 990GB available
