itunes not detecting iphone 12

My PC also sees my iPhone 12 Pro Max but merely charges it and not a lot else. This is definitely not something we're going to fix ourselves and can only come about by way of an update.

I'll try my iPhone again tomorrow plugged into my PC after tonight's nondescript download through the Mac to see if that makes any difference. I'm not holding my breath, obviously.

I have the same problem. I plugged in my new iphone 12 but still shows the old iphone 10. My music in iphone 12 dont play (grayed out). Maybe we have to wait until the apple tech guys catch up to resolve the issue.

I reported this to Apple support. After over one hour on the Phone they have my iPhone 12 mini generated support data and my MacBook Pro 10.11.6 sysdata and will get back to me after 24-48 hours. With xmas I guess it might be longer. I’ll update if something useful comes out.

I had no issues with the last OS, this has only been happening recently in Big Sur. However its not restricted to Big Sur. I can only get my phone to read on my newer iMac in a new user account I created when trying to fix another problem with Final Cut not opening. If the computer can read the phone under a new user then its clear there are some sort of files within the Library (at least for Mac, I dont know about PC nor do I care) that need to be found and removed. Its sort of a process of elimination at this point while Apple Techs dont have a clue themselves.

Thank for documenting all of this. I'm on an older MBP too (mid-2011), and I'm having the exact same issue. Everything you described above applies in my situation as well (with the exception of the USB cord - though I did reboot the phone).

I did the same thing, tried everything with normal lighning to Usb cables, install different version of Itunes to various windows versions and computers but it never recognigh new iphone 12. Finally I come to this site and see your post, try it out and it WORKS, THANKS a bunch.

Oh my god, thank you so much! That solved it for me!

I really hope Apple will become aware of this problem with Ryzen platforms and provide a fix that doesn't rely on users getting the lucky idea to try out every single USB port of their mainboard until one eventually works.

I spent 2 hours with the apple support earlier this day because of this problem and they said there was no knowledge about compatibility issues with AMD Ryzen when I mentioned it.

I have the same problem. I tried everything that all help pages asked me to do. I spent time with apple support and they are telling me I may have defective computer. I am using new HP pro laptop. I am very disappointed in Apple support where they are not willing to solve the issue. It does connect with my 10 year old computer. So, apple is saying it is not phone issue. There is something with iphone12 or itunes which does not allow it to be recognized by itunes. Apple needs to pay attention to this.

Hi t0r.

Thanks for the latest gen. How does the replacement iPhone 12 Pro Max exchange work during lockdown out of interest?

I certainly wouldn't want to be without my iPhone 12 Pro Max even for a day at the moment but obviously keen for Apple to replace my iPhone.

Dear t0r

Many thanks for your response.

All the UK Apple stores are closed at the moment but was interesting to read your posts and I'll wait until the stores are open again before booking a Genius Bar appointment to request a replacement.

I've also managed to persuade iTunes to recognise my iPhone 12 Pro Max on my PC [no problem on my Mac] by an alternative method which is detailed on the last post of page 10 of this thread.

No one in their right mind would accept a refurb during the warranty period and Apple wouldn't replace your new 12 Max with a refurb either.

Also a good time to understand model numbers, particularly if one purchases Apple products from eBay etc.

Another one here - also a home built Ryzen 5. Showing up in W10 but not in iTunes. Makes no sense whatsoever. Would love an apple rep to comment on all this. Really frustrating!

iOS 14.2 just came out. Have any of you updated and tested again? I am about to update now and test it.

@vuongsta2 Any update on bringing your phone to Apple to run diagnostics?

Updated to 14.2 and still does not recognize

@prosteak no luck for me either. I've bought a USB-C to USB-A adaptor to see if, for some reason, that helps with the sync.
