This from the Yasu website: Important Note: Yasu can take a long time to run. It may seem as if the application is not doing anything, but rest assured that it is. It should be left alone to complete the tasks you have chosen to perform. It is recommended that you not run other applications while performing maintenance with Yasu. Also, you should be aware that if “Restart” or “Shutdown” when finished is selected, your workstation will do just that once all tasks have completed. Also 10.6.4 is the latest update out. If you are running a hypothetical 10.6.5 then you better check your NDA. Cheers
