After I bought my new iMac (and stuffed it with memory from OWC) I decided to start fresh instead of simply transferring all my data over from my older Mac. Everything went smoothly … at first.
However, when I went to download all my purchased iWork apps (Pages, Keynote, Numbers) from the Mac App Store, I got this message when I tried to update Pages: “Unable to update Pages’ To update this app, you need to accept it on the Account page in the App Store.”
I had never run into this in all my (many) years of using a Mac. After a lot of experimentation and looking for online help, I found the solution. If you run into this situation you should:
Open the Mac Store App and make sure you’re signed into you account.
Go to Store > View My Account.
Then click Accept.
Once I went through these steps, everything worked fine. Whether this is something new that Apple is implemented, I don’t know. However, if you run into the problem, now you have a fix.
