Empty progress bar in Launchpad

After a recent hardware failure I was forced to replace my iMac’s internal hard disk (more on this some other time, perhaps). One of the decisions I made was to move down from a 1TB HDD to a 512GB SSD, so rather than restore from a backup I reinstalled all my applications from scratch and moved my large Lightroom and iTunes libraries to an external HDD.

This is progress? Launchpad dock icon stuck on 0%

One of the side effects of reinstalling two or three dozen applications is that Launchpad’s progress bar got a bit confused. By the end of the afternoon it was stuck on 0% progress and looked like the image to the right:

Mildly irritating, but not the end of the world. I’ve lived with this for a couple of weeks now, expecting it to fix itself when I installed a new application. It was only today that I noticed that it was still broken and decided to do something about it.

Some Google research turned up this Terminal command:

defaults write com.apple.dock ResetLaunchPad -bool true; killall Dock

This solved the problem nicely.
