ITunes sign in "Unknown Error" on my Mac only.

I get the "Unknown Error" in iTunes only. My password works on all other devices. Then when I try to sign in iTunes more than 3 times, I end up having to reset password again. This is only a problem with iTunes on my Mac, not iphone or ipad.

I received this email from Apple and this corrected the problem for me... I only had to reset the iTunes cache
1) Open iTunes
2) At the top menu, click File > Preferences (iTunes > Preferences on a Mac)
3) In the Preferences menu, click the Advanced tab
4) In the Advanced menu, you should see a button that says "Reset Cache". Please click this button.

Could not sign in Unknown error.

Have had my Apple TV for over a year on the same iTunes account, working flawlessly. All of a sudden today, I get random:
Could Not Sign In
Unknown error.
Messages.
Restart - nada. Power interrupt - nada.
Log off and try to log back in in settings: same message every time now.
Help!

Sort of. I did a full restore from settings, which resets it to factory settings, but with the latest software update. Then had to set it up like new, and re-login or register apps like MLB, Netflix, Hulu, etc. Took over an hour, but the problem hasn't been back since. Kind of sad that no one replies on these forums, including Apple support. I'm full Apple technology ecosystem in my home, but have started to shop other devices now after this experience. Technology issues I can take. Lack of support, not so much.

Excellent it worked for me.
First I tunes was unable to update software so I removed then deleted installed program folder location after that properly performed clean installation for itunes64.
When tried to sign in received this message. Even restart the pc did not help.
Your help was fruitful.

Try this...
Triple click anywhere in the line below to select it and press Ctrl+C to copy it.
cmd /k netsh winsock reset
Press the WinLogoKey+R to open the run dialog, then Ctrl+V to paste, then press enter/return.
You should get something similar to this:
Reboot the computer and the problem should be resolved.
If it doesn't work then perhaps a full tear down and rebuild of iTunes will fix things. See Troubleshooting issues with iTunes for Windows updates for details.

Hi, i had the same problem. Try to find the file "apple" or "itunes" don't know it anymore exactly. Ahm well you need to delet any information or just plug in your iphone into an other computer. important is that your iphone never has been pluged in this computer before. This was what i did, and it worked!

ITunes 10.7 unknown error -1500 when connect to wireless speaker. OS X 10.75 Any thoughts?

iTunes 10.7 unknown error -1500 when connect to wireless speaker. OS X 10.75 Any thoughts?

For reasons unknown I found copies of many of these tracks as 256 kbps .m4a files in my Trash. As such I was able to remove the existing 128 kbps .m4p (Purchased) files (but not deleting them from iCloud), add the 256 kbps .m4a files to iTunes and then Add to iCloud whereupon, the original 128 kbps listings with the download from iCloud link switched to 256 kbps (Purchased) files. For a few of the files I accidentally deleted the 128 kbps (Purchased) from iCloud and when I added the .m4a to iCloud they appeared as 256 kbps (Matched) songs instead. Not sure why the difference, but it worked for several of these problematic files. But I still don't understand why/where these .m4a versions came from as most of these purchased predated iTunes Plus (e.g., my original purchases were 128 kbps). My new list of recalcitrant files is:
Anna Nalick: Breathe (iTunes SOTW)
Coldplay: Parachutes (tracks 4 + 5)
Dave Matthews Band: Stand Up (tracks 3-6, 11, 12)
Feis: One Evening (iTunes SOTW)
Future Leaders…: Let Me Out (iTunes SOTW)
Hinder: Get Stoned (iTunes SOTW)
Living Things: Ahead of the Lions (iTunes SOTW)
Low Millions: Eleanor (iTunes SOTW)
Spymob: Sitting Around Keeping Score (iTunes SOTW)
As you can see, most of these are iTunes single of the week (SOTW) offerings, so I'm not too bothered about them.
