I got error message 4001 when trying to upload music to imatch

on the mac, option = alt. Maybe try holding alt. If that doesn't work, ctrl or windows key.

OK the "Options Click" solutions worked for me I can finally use my iPhone 4 with iTunes Match wow that was a hassle but thanks to this post it works!

Same here. Option + disabling Match didn't fix my 4001 issue, but right-clicking to upload an individual song did seem to get it jump-started.

KMKazie solution worked. I had tried everything else for days!! Thanks KMKazie!!! (see below)

I came from the other thread of the same issue. Just I wanted to post the other way resolved the issue, for some reason, for me. I did these:

1. Press Command-J > Check iCloud Status checkbox.

2. Select one song in 'Music' > Right click the song > Click "Add to iCloud"

And it started the first step in the Match. And it went through the step 2 without the error! The process is now in the step 3, uploading songs. Weird, but this was the way the issue was resolved in my case.

Neither the option click or right click adding an individual song to the cloud work for me 😟 I actually beta tested and it worked now cant get past the 4001 error to save my life.

Sorry man. Right click and add to iCloud workd for me. I feel your pain.

Reinstalled iTunes and now match works go figure. Lol

Like others, I am having this difficulty as part of my participation in the beta trial. I tried to update genius with no luck. I deauthorized and then reauthorized my computer, also no luck. I continue to get the 4001 error.

Yup, that worked for me too. While holding down the option key, choose "Turn off iTunes Match". Then turn iTunes match and all is well. I have know idea why that would work but it did after trying everything else.

I recieved useless links from support, not a single one of them references the 4001 unknow error. Thanks to those who posted holding down the option key while turning off iMatch. So far it seems to be working. I now have about 2000 of 9000 songs match and counting.

Yay! Pressing option key while selecting "Turn off iTunes Match" and then reenabling it again with a normal click did it for me!

As far as I know, what you can do with the option key on Mac, equals pressing the shift key on Windows.

Thanks. I was getting the same on Windows. Using the shift key for option worked for me

Anyone have any other ideas? I have tried absolutely EVERYTHING mentioned and I can'y get mine to work at all. I wasn't a beta, I have started a ticket and support isn't being of much help.....Any help would be greatly appreciated.

Indeed; Turning off Match while holding down the Windows Shift Key, then turning Match back on allowed Match to continue.

I was finally able to fix it by selecting a single track, right-clicking and sending it to match and the rest followed! The Option Key method never worked for me.
