Mac System Software 4.1 was released on 1987-03-02 and released with the Macintosh II and SE. Mac 512K support was dropped because 4.1 needed a minimum of 1MB to run. It includes an updated LaserWriter driver, AppleShare 1.1, the way the Finder handled drives larger than 32MB changed, and Find File can now move whatever searched file to your desktop.
