unable to connect iphone to macos catalina

Hi libitgeo,

It sounds like you're having some trouble connecting your iPhone to your Mac, and I want to help.

Check out these steps that can help when your iPhone isn't detected by your Mac:

If your computer doesn't recognize your iPhone, iPad, or iPod - Apple Support

Let me know if that helps.

Thanks for using the Apple Support Communities.

I actually just tried a different port, and now it works fine. I guess the first two ports I tried didn’t work. Still

stupid that something so silly

is what wasn’t working.

I observed the same issue when connecting using iPhone 11 latest IOS and MacBook Air with Catalina latest OS update.

Iphone 11 shows up in finder for a couple second and then disappears. Very frustrating.

This happened to me last night; the computer said I needed to reset the phone to factory. I was suspicious, and called Apple Support, who indicated that my iMac needed a version update (no notice of a software update had come in to the computer, btw). I also found that there was a software update for my iPhone (also that had not yet been served to the phone). Once I updated everything, I was back in business. It was very frustrating, though -- and annoying that the original error message would have been totally unnecessary.

I tried everything but it's not connecting, I am using iPhone 11 latest IOS and macbook pro with latest OS update.

Device showing in finder for a couple of second and then disappear.

Hi , did you solve the issue , i having the same problem the iphone 11 pro show up for a few second and then disappears

Nope. Not yet.

I have the same issue

Same issue. Ever since I updated my iMac to Catalina. Frustrating. Thanks, Apple. Ugh. Why bother??

All my devise are updated but still have the same problem, as soon i have time i will try to restore the phone, i am very upset since my phone is new

Yes, this is my exact issue as well. It's incredibly annoying and the troubleshooting steps don't address this. >> "Device showing in finder for a couple of second and then disappear."
