Repair Keychain to Fix Slow OS X Lion

For many users updating to OS X Lion borks the keychain causing multiple errors to be written to the console. These error can cause a system running Lion to hang or to run slowly. To fix these errors, these directions will show you how to repair your keychain to speed up your mac system.

After updating to Lion, I noticed that my system has been running slower than I expected. The worst problem was TechTool Pro causing Lion to hang and crawl. However, even after fixing that issue, I noticed that occasionally my system would slow down. During this time, I would notice an ton of excessive errors messages being logged to the console. For example, I would see hundreds of these:

WebProcess(243) deny file-read-data /Users/davak/Library/Application Support/Adobe/AIR/ELS/ com.adobe.amp.4875E02D9FB21EE389F73B8D1702B320485DF8CE.1/ PrivateEncryptedDatak

example of excessive console messages

1. Open Spotlight by pressing the magnifying glass in the upper right-hand corner of your screen.
2. Starting typing in Keychain Access and select it when it appears. You can also find the app in the Utilities folder in your Applications folder.
3. Press the Keychain Access menu
4. Select Keychain First Aid

5. Insert your password and select Repair. Press the Start button.

This will correct permissions and other various issues that commonly occur with the keychain. In my situation, it knocked the painful problem I was having with Adobe Air:

Checked contents of ~/Library/Application Support/Adobe/AIR/ELS/ com.adobe.amp.4875E02D9FB21EE389F73B8D1702B320485DF8CE.1/PrivateEncryptedDatak
Problems successfully repaired

If the errors continue, then I would uninstall the application that is causing problems first. Then I would delete all the contents in associated its Application Support folder. So in this example, you might need to uninstall AIR and then delete everything in the ~/Library/Application Support/Adobe/AIR/ folder. Then you’ll even need to clear the Trash to make sure the evil little guy is gone.
