Launch your application, oh look, an update! Clicking
"Update" takes you to the Mac App Store web site.
Click "View in Mac App Store" since apparently I'm not doing that
yet, but wait!
Tell my browser that it's okay to do what I just told it to do.
We're launched into the Mac App Store app, so we need to click the grey
on grey "Updates" button / tab / thing...
And click "Update all" or just "Update".
Sign into my Apple account for some reason.
Oh we need to quit the app. Command-Tab...
Quit the app.
Back to the Mac App Store app again.
It's updated and I can launch it again.
Ten only marginally confusing steps!
At least they got the gradients, drop shadows, rounded corners and noisy backgrounds right.
