What was the introduction date of this line of Macintosh portable computers, introduced in conjunction with the MagSafe?
MacBook Pro The MacBook Pro (sometimes abbreviated MBP) is a line of Macintosh portable computers introduced in January 2006 by Apple Inc. Replacing the PowerBook G4, the MacBook Pro was the second model to be announced during the Apple–Intel transition, after the iMac. It is the high-end model of the MacBook family and is currently available in 13- and 15-inch screen sizes. A 17-inch version was available between April 2006 and June 2012.
Workgroup Server 9150 The Apple Workgroup Server 9150 is the only Apple Workgroup Server model not based on a desktop Mac. It featured an 80 MHz (speed bumped to 120 MHz in April 1995) PowerPC 601 board in a Quadra 950 style case. The internal bay of the 950 case was filled with a tape backup drive. Atypically, the floppy drive was moved to the bottom of the case, the only Macintosh that ever used this configuration, and uses a regular Mac DA-15 video connector instead of the unusual internal video connector of the other early Power Macintoshes.
