iTunes won't open after latest OSX update

Having same issue

Same issue.

Same issue.

Mac Pro (Early 2009)

OS X Yosemite 10.10.3

This is what worked for me and others--original post found on this thread: Yosemite slow opening and cannot open itunes

This solved my question by Linc Davis.......

According to multiple reports on this site, Apple Support has given the following instructions to others who had a similar problem. I can't confirm that this procedure works or that it's necessary, but it won't leave you any worse off than you are now.

First, back up all data.

Select the iTunes icon in the Applications folder and open the Info window. Click the padlock icon in the lower right corner to unlock the settings.

In the Sharing & Permissions section, change the Privilege setting for each Name in the list to Read & Write. Close the window. If the settings aren't visible, click the disclosure triangle on the left so that it points down.

You should now be able to drag the iTunes application to the Trash and empty. Your iTunes data won't be affected.

Click the iTunes link at the top of this page, download the installer package and run it.

If iTunes still doesn't launch, or if you can't complete the procedure, reinstall the OS.

Unistall-reinstall iTunes procedure worked for me.

Hey thanks Glenn. I spent hours with Apple and no fix. This worked like a charm. I sent your post to them.

Best wishes, Jim

Thanks, your solution worked great! I'd been looking for a way to get rid of that more than serious problem since the last update of Yosemite. Now i'm less furious against those more and more complicated OS. You made my day... 🙂

Thank you so much, Glenn! 🙂
