mac itunes you do not have enough access privileges for this operation

This has been hours hours of repairing, restarting, setting another itunes library, moving everything again and again.

Then do Command-I (Get Info from the File menu), click on the padlock icon in the lower right of the new window.

Select Read Write if its on Read Only, Write Only, or No Access.

Now having your user account with Read Write privileges (it may have been this way already; still do this next step), click on the gear on the bottom-center of that window.

When the pop-up says Are you sure (or the equivalent), say yes.

This will grant access privileges to your user account for all the music files inside your music folder--all your iTunes stuff included).

There was a problem downloading You do not have enough access privileges for this operation.

Please check that the connection to the network is active and try again.

I knew to try to repair permissions AND changing the ReadWrite status on the iTunes folder in the Finder.

I had to basically setup a brand new iTunes library, download everything from the iTunes Store and setup every single device associated with iTunes all over again.

Now that Ive done this, its been 1 week without any issues.until today.

Ive repaired the permissions more than I care to admit.

Nada. Ive got the iTunes folder (and everything within it) so writable that my dog has access to write to the folders.

Tunes will NOT let me add any media, downloads, or anything to the library because I do not have access privileges.

Somethings got to be wrong at the root level and this is affecting my phone, and all other devices.

Can anyone help (By the way Im not a total noob since Ive been using and advising with Apple products for over 20 years--so any advice you can bring OTHER than repairing permissions and Get Info in the Finder will be most appreciated.).
