Update: Mountain Lion 10.8.1

Mountain Lion update 10.8.1 was released on Aug 23, 2012. I did not rush to update my ML. Two days ago I noticed my App Store had several updates, 10.8.1 was one of them. I did not click on update right away. I double clicked on the update item, then I saw a pop up option with "Hide". I clicked on Hide. Suddenly all the update were gone.

I could not find a way to bring hidden updates back. I tried to quit App Store, then reboot my Mac. Still I could not see updates. I thought it may be back later. Today, I still did not see it. I found a way to unhide items from my accounts in App Store. I only got the other two items back, not the 10.8.1. I checked my Mac. It was 10.8.

Then I decided to search for the web if some one else could have similar issue. Soon I found the update on Apple's web page. Here you go, I can get the update from Apple web page. I am so fortunate that this update is available from Apple. Not sure if other updates would be hosted on Apple download page. I doubt if there were.

Since I did not get the update directly from App Store, I don't know how it works. Should that be automatically in a silent mode? Should the download be deleted after update?

The download version is a normal package installation. The package was saved to my Download folder. I had to click on the package of OSXUpd10.8.1.dmg, with 24.2MB in size. The package in exploded to pkg. Click on the pkg, the installation wizard is displayed.

I thought ML's update feature would be done in evenings automatically. So far, all the updates I found from App Store require my interaction to complete. Not sure if there is any thing I miss in the system config. Anyway, I still have chance to compare the disk space difference between before and after.

The following is the comparison of spaces used before and after of the updates:

Command: df -lakUsed(Kilobytes in 1024-blocks)
Difference (A-B)161,976
