In the third act of "Terminator-3", the Terminator reboots himself, to rid his system from corruption caused by the T-X. As he does, we can see, in his first-person "Terminator Vision", many items scroll by. These include:

Remote Access
Sound
Memory
Software Update
QuickTime Player
Control Strip
Date and Time
Multiple Users
Keychain Access
Location Manager
Energy Saver
Add Application Program
MP3.com

All of these items (with the exception of "MP3.com") are easily recognized components of Apple Macintosh operating systems, most likely Mac OS 9.

In "Terminator-1" shots through the Terminator's vision shows a dump of the ROM assembler code for the Apple II operation system. If you own an Apple II, enter at the basic prompt: ] call -151 * p This will give you the terminator view. Other code visible is written in COBOL.
