iPhone sync window in Catalina problem - iPhone Finder window just disappear

Hi i_rina!

Thank you for your suggestion.

Unfortunately, that isn't solve my problem. I was tried several more things, but without success.

My Mac recognize iPhone (iPad), there at the left side in the Finder column iPhone is visible. Furthermore, I can see iPhone sync screen on the right side in the Finder window, but somehow that screen disappear after about 3 seconds (during that 3 seconds, nothing in that sync window is clickable).

In the Finder left side column my iPhone still remain recognized, but without right hand window (like on my previously attached screenshot).

My iOS devices is also recognized in Music App (ex iTunes), and is visible in System information in USB devices.

Everything was ok the first week after the Catalina installation, but now that sync window disappears.

Cheers!

Hi!

Thanks for that suggestion. I tried all of that suggested procedure but unfortunately doesn't work.

Btw, before all of that, I disconnected all other USB cables from iMac.

Firstly I tried with a new account, but the problem remained the same.

Then I tried with safe mode and the problem remained.

After that, I tried again with that new account and again doesn't work.

In every try, my iPhone was recognized in System information in the USB devices.

One difference, in safe mode, iPhone wasn't visible in Finder left side column, but I'm not sure that in Safe mode everything needs to works the same as in normal mode. I checked in Finder Preferences and CD, DVD, iOS box was ticked.

In all other tries, iPhone was visible on the left Finder column, but on the right window, as I said in the previous message "I can see iPhone sync screen on the right side in the Finder window, but somehow that screen disappears after about 3 seconds (during that 3 seconds, nothing in that sync window is clickable)".

Then I tried one more thing. My actual OS Catalina Version is 10.15.1, and I started iMac from my backup external disc (CC Cloner bootable backup) with a backup copy from 31st October with Catalina 10.15 Version, and everything works perfectly with that version.

Just one additional information, I have connections problem with my iMac 27 connected with my iPhone7 and iPad Air2, but also my office colleague has the same problem with MacBook Pro 13" Mid2012 connected with iPhone XS and with iPad Mini2.

That MacBook Pro also has Catalina 10.15.1 but also works perfectly with 10.15 Version.

MacBook Pro and iMac are not connected, they work separately.

Cheers!

Hi nenonovak!

The problem isn't solved yet, but I am in contact with the Apple support team and we tried the last several days to localize the issue.

Today's new information is that Apple engineers now working to fix that issue, and a macOS Catalina update should be available soon. We hope that the problem will be resolved with that update.

But also check if there will be an iOS update available soon, there may be some changes too, to fix the problem.

Cheers!

Hi,

As I mentioned in my previous message, I was in phone contact for several days to Apple's senior advisor and Apple engineers and after all of our trials and tests they determine at the end that this is software problem and they tell that should be soon resolved with an update on macOS Catalina.

Hopefully, then everything will work out fine, we just have to be patient a bit more.

They tell me also that I need to check if there will be an iOS update available soon, It is possible that some changes will be made there as well, to fix that problem.

Hi,

I have also updated to the new version of macOS Catalina 10.15.2 and iOS sync window in Finder now works fine on both iMac and MacBook Pro.

Cheers!
