"This iPhone is Open in Another Window" error

On Ventura they moved the sync page from iTunes to Finder ,or open any folder ,on left side look for devices , click on your iPhone and there it is :P, that window moved to finder ("This iPhone is Open in Another Window" - no error , just a minor rearrange )

It is absolutely correct. You need to Force Quit Finder. You do that by COMMAND+OPTION+ESC or choose Force Quit on the Menu, click on Finder, and click Relaunch. This will kill Finder, and release the iPhone window.

Your theory is not correct. It is because when the iPhone is connected to Finder it cannot also be connected to Music (or Photos).

Yes, whew, my iTunes was looking at iTunes Store. I clicked on (My) Your Library, and could then see all the music on my iPhone. Silly little thing. Never experienced this hangup before. Thank you for the helpful suggestion (and this Forum).

The iPhone controls are now found under "Finder" -> iPhone. If you click on the iPhone in the Finder Window the controls for the iPhone are there. (October 16, 2023)

Your second option worked perfectly for me (But a quicker fix that worked for me is: clicking on the iTunes Store, on the left hand side of the Music (iTunes) window, then clicking back on your phone.)

Obviously, there is a pretty serious bug in the Music app.

My understanding is that since Apple replaced iTunes with Apple Music, the MacOS Finder manages physical syncing, including the interaction with the itunes db. Apple Music is just attempting to notify you of that fact. Assuming that is your issue, you should be able to click on your iPhone in Finder and manage the sync there.

In the image below, you can seethe Finder window on the right in the foreground managing the iPhone syncing via USB cable. On the left in background is Apple Music with the message "This iPhone is Open in Another Window"

The other window is Finder. Go to the Menu, Force Quit, click on Finder then click Relaunch. Or you can also sync using Finder rather than music.

I don't know why Apple can't just tell you this. If you look in FINDER, your phone looks as if it's a drive. click it and all the old menus will show and you can proceed.

But a quicker fix that worked for me is: clicking on the iTunes Store, on the left hand side of the Music (iTunes) window, then clicking back on your phone.

^THISSSSSS!!!!

THANK YOU!!!!

Ignore the “///“ and just hold CMD and Option and press Esc.

Every Mac comes with Music. “Music” is the new iTunes. And within the left panel, in Music, there should something labeled “iTunes Store”. Clicking that, in the left panel, then clicking back on “iPhone” should fix the issue.

But a quicker fix that worked for me is: clicking on the iTunes Store, on the left hand side of the Music (iTunes) window, then clicking back on your phone.

This works like a charm!!

Finally! Thanks do much. Simply clicking on the iTunes Store above My Device then back worked for me. Cheers

Clicking the iTunes Store and back to the iPhone in the sidebar worked like a charm, thank you!

I had the same problem with an old iPod Nano 2nd Generation. It was recognised by any Mac. I reset it but in Music it was shown as being open in another window. I followed someones reply to click on iTunes store then click on iPod and it worked.

How hard is it for Apple engineers to solve this? Seriously?

There is nothing for Apple engineers to fix, it is working as designed. The iPhone IS open in another window, Finder, specifically, and it is open there because you didn’t close it the last time you synced or backed up your phone. Just relaunch Finder from the Force Quit window.
