Macintosh Performa 6400: Stopping Intro at Startup (8/96)
How can I stop the Performa Intro from appearing when I start up my Macintosh Performa 6400 series computer?
There is an alias called "Launch Performa Intro" in the Startup Items folder, which is in the System Folder. To prevent the intro from playing at startup, remove this alias from the Startup Items folder.
