Mac App Store Troubleshooting
Purchase Failures
- An unknown error occurred (100)
The solution is typically a simple one: Quit the App Store and wait a few seconds. Then relaunch the App Store and try again. - App purchase doesn't appear to complete
Just try again—clicking the Buy, Install or Resume button as relevant. If you cannot find a previously purchased app in the Purchases list, and you are correctly signed in to your account, press Command-R to refresh the page.
Sign in Failures
- Sign in sheet does not appear, or does not accept typed text
The likely problem here is third-party system enhancement software. Apple specifically cites Unsanity’s FruitMenu and APE (Application Enhancer) as causing this. The solution? Disable the third-party software. Hopefully, a future update to the software will resolve the conflict. - Unresponsive after clicking Updates icon — App Store app freezes
This is a rare symptom, triggered by “certain third-party Mac NTFS software and/or connected partitions with versions of Microsoft Windows that contain the NTFS filesystem.” The solution is to remove the NTFS drive/partition from the Spotlight search list. As an alternative, if you can determine the specific utility that is causing the symptom, you may be able to disable it from the utility’s own preferences.

Mail 4.4

- Can Apple Mail be optimized to perform well when I have 30k messages in my inboxes?
- Vacuuming your Mail.app index still works wonders
- How to make Gmail work well with Mail
“The crux of the conflict when using Mail as a client for Gmail is labels, Google’s alternative to traditional e-mail folders. Instead of filing messages into single folders like Mail and most other clients, Gmail essentially lets you tag e-mail messages with multiple words like you can with photos on Flickr or bookmarks at Delicious. Because you can apply as many labels as you want to a message, and Google creates an All Mail folder to collect every message in your account, working with Gmail in Mail can get clunky, and fast.”
