trouble signing into mac app store for updates
The app store icon in my launchbar indicates that I have 3 updates available, and I would like to update. So I click the "update" button next to each item, and I am asked to sign in with my apple ID. I do, then I receive a message saying more info is needed, and I am redirected to a web site that explains what an Apple ID is and how to create one. I know I am entering my ID and password correctly because when I try doing it another way, I get the "incorrect ID or password" mesage. And of course, I managed to sign in to the Apple Support Community.
So how do I get my updates?
Any help is appreciated!
