  The Apple Macbook 4.1 refers to Apple Computer's line of consumer portable computers, and specifically the model that sold between February 2008 and January 2009. It came in black and white molded plastic and served mainly as an incremental release. The addition of slightly faster processors is the major difference between the Macbook 4.1 and the 3.1 from late 2007.
  
  

Hardware

• The Macbook 4.1 employs a 2.1 or 2.4 gigahertz Intel Core 2 Duo processor. This 64-bit processor is paired with an 800 megahertz system bus. These systems shipped with a standard 1 gigabyte of RAM and are expandable to 4GB via user-accessible slots located behind the battery. The Intel graphics accelerator X3100 drives the Macbook's 13-inch diagonal screen. Included ports include one gigabit Ethernet port, two USB 2.0 ports, one six-pin FireWire 400 port, and a Mini DVI port that could be expanded with additional adapters for DVI, VGA, Composite Video, and S-Video, which were available for purchase. Additional hardware features include a built-in iSight video camera, Apple's magnetic MagSafe power adapter, and a slot-loading Combo Drive optical reader.
  
  

Software

• Mac OS X 10.5.2 Leopard shipped with the Macbook 4.1, and because of its 64-bit Intel architecture, it remains expandable through Mac OS X 10.6. In addition to the operating system software, these Macbooks came with Apple's iLife 2008 suite of digital lifestyle applications including iPhoto, iMovie, iDVD, GarageBand and iWeb. The iTunes music player came pre-installed, as did Apple's Photo Booth program, which uses the build-in iSight camera with pre-set artistic effects.
  
  

Considerations

• As of mid-2010, these Macbooks use contemporary technologies, and will only begin exiting extended warranty periods at the beginning of 2011. Apple will not consider these machines "vintage" until October 2013 and "obsolete" until October 2015. Under Apple's standards, vintage machines are ineligible for hardware support, except for those purchased in the state of California, and obsolete machines are afforded no hardware support without exception.
