Mac App Store not working - showing very odd behavior
I'm currently running Mac OS X 10.10.1, and my mac app store is doing a few things that are making it unusable.
Here are the symptoms:
- The promotional image at the top of the "featured" section won't load (not a huge problem)
- When I click on "Get" to download an application, nothing happens. The button clicks in and out, but nothing downloads, and I get no error message. Simply nothing.
- Under the "Store" menu option, my account is shown as logged in. However, when I click on the "Purchases" tab, it says I must logon to view my purchases. I'll click on the "sign in" link it provides, but nothing happens - I am not prompted to sign in.
- Many other links do not work, include: "Welcome" and "Account" from the "Feature" tab
- The "Update" tab icon shows that I have 2 updates available, but when I click on it, the page does not load. I am presented with a white screen.
- When I click on "Redeem", I am prompted to log in (although I am already logged in). If I reenter my username and password and hit enter, I get caught in an endless sign in loop, and it continuously asks me to sign in.
- Otherwise, I can browse the "Featured," "Charts," and "Category" tabs. I see the apps and view their information. I just can't download them. As I said, when I click to purchase, nothing happens.
I've tried all of the fixes: deleting the cache, resetting the PRAM, fixing certificates... I've spent hours trying to fix this. It seems like it's so broken that I just need a clean install. I'm considering backing up my computer and then reinstall OS X, because it's difficult to not have a working app store. Are there any other solutions?
