URLs with the type "file" not supported

I just did this and it worked. Found it on another question. Go to Macintosh HD>Library>Preferences and look for the file com.apple.TimeMachine.plist. Delete it and restart the computer. A new clean file will replace the old one.

Did it and no more error message.

I did this and it sees to have worked as well!! But the strange thing is that the com.apple.TimeMachine.plist file that I deleted was only four days old. It must have been updated with the latest OS update (Sonoma 14.5), but this has been going on for much longer than that.

It used to be that with an OS update, this would disappear for a while, but if I had to reboot, it came back. But with the last two OS updates, it didn't disappear.

Hopefully, it doesn't return. I think it's ridiculous that Apple doesn't know about this and doesn't fix it.

Yes, brn2rnjk1, you should try that. In my case, I didn't have the com.apple.TimeMachine.plist file, since I'd never run TimeMachine on this machine.

None of solutions worked for me. Actually, made it worse. Tried deleting items in background. Sonoma doesn't have a com.apple.TimeMachine.plist.

Personally, I fixed it by disabling some "Allow in the Background" items and restarting. I think, but I'm not positive, that the one that actually stopped the obnoxious behavior was OSMessageTracer. I don't know where that item originally came from, but disabling it seems to have worked, and it hasn't been an issue for me for almost 3 weeks now. If you don't have that item listed, you might have something else that's running in the background that's the culprit.

What are you trying to do exactly? Connect to a local work based server? Windows or MacOS? What is the URL you are using exactly?

Apple was not able to help me fix it. What did they tell you that fixed it?

I'm getting this all the time now. It was just occasional before I upgraded to Sonoma

Same exact thing here. And apple support couldnt trouble shoot it over the phone

What did you do? They were not helpful with me.

I did this and it’s fixed. Apple support told me it was probably a bad internet connection but my internet is great. This fixed it though I am so grateful 😊
