Iphone 12 / High Sierra / Itunes 12.8.2.3

"Get a new Macbook." Yea, like we all have money to just get a new one!! I love Apple products but they do seem to make you upgrade to get some devices to play well together.

Yes, maybe a fresh start tomorrow will work!! Keep us updated.

I have a similar issue, running the same versions of iTunes 12.8.2.3 and OS 10.13.6, and my Mac doesn’t consistently find my new iPhone 12 (it doesn’t appear in Finder or iTunes, but does appear in Photos). Can’t update further because of the age of my machine.

Question: when I look in the location you describe, there is no MobileDeviceUpdater. I do see MobileAssetUpdater and MobileAccessoryUpdater, but I assume those are different. Any thoughts on this?

Found it, thanks! But when I run MobileDeviceUpdater nothing seems to happen. In any case, it didn’t fix the underlying issue after trying to run the updater and restarting. Neither did reinstalling iTunes or the other suggestions on the thread.

Have you tried my suggestion above? The feedback is generally positive.

I had the same thing happen with the "Remote Disc!"

Any options if you right-click on this Remote Disc?

I'm at a loss then. 😕

thanks tymmac, it didn't work for me :-(

thanks for sharing

It took me a try or two to get it working. It's very frustrating, I know!!

Hi tt2, everyone,

No malware or vpn present, and rebooting router didn't help.

However - I did solve the issue.

I had a spare 15" A1286 Macbook pro running sierra. I don't use it as there are ram slot issues on the motherboard, which cause constant hardware crashes.

I swapped the HD of my normal daily 13" laptop into this 15" laptop. When it started up, I plugged the iphone 12 into the 15" laptop. This triggered the software update process, which made it possible to see the iphone 12 on this machine. Itunes didn't need to be open - it just triggered an update from the finder.

I then swapped the HD back into the 13" laptop, as well as cleaning the USB contacts thoroughly with isopropyl alcohol.

Upon restarting the 13" laptop, and starting itunes, it now recognises the iphone 12, and I've been able to back up and sync.

I suspect the issue might have been as simple as dirty ports on the 13" laptop. The 15" (other than being crash prone due to the motherboard issue) was a lot cleaner and well kept. Perhaps the new iphone 12 requires a more consistent voltage compared to the old iphone 5?

Quite an involved process, but maybe try cleaning the usb ports first. I also spoke to Apple support about this issue.

Running high sierra, and itunes 12.8.2.3 with ios 14 and and iphone 12 IS a supported configuration, and will work, as long as there are no hardware issues (eg bad cable, dirty ports).

Cheers

What did you do next? the MobileDeviceUpdater doesn't seem to be doing anything now when i click on it.

One thing that is also started to happen is Photos now open as soon as i connect the iPhone but i cant see/access anything.
