Marc Moini has released Clean-Install Assistant 1.2. Clean-Install Assistant automates the tedious task of manually moving third-party files into the proper folders when performing a "Clean Installation" of system software. This release is just in time to save many headaches switching over to Mac OS 9. According to Mr. Moini:
Clean-Install Assistant makes it easier to migrate third-party and personal items to a new Clean-Installed System Folder, and it may also be used to:
Save space and backup your valuable additions and preference files only, instead of the whole System Folder.
Install the same set of additions on multiple Macs.
Remove extra files and folders from your System Folder to restore it to a previous state: you can take a 'snapshot' of the System Folder and have Clean-Install Assistant extract any items added since.
Version 1.2, released today, adds support for Mac OS 9.0.
Clean-Install Assistant is free for personal and educational use, with business site licenses starting at US$50. You can find more information at the Mark Moini.com web site.
