In May 2007, version 2.0 of the driver (xorg-video-intel) was released, which added support for the 965GM chipset. These drivers were developed for Intel by Tungsten Graphics. In August 2006, Intel added support to the open-source X.Org/XFree86 drivers for the latest 965 series that include the GMA (X)3000 core. See also: Free and open-source device drivers: graphics § Intel Work to integrate GEM and KMS is currently adding support for i-series integrated graphics and improving support for earlier chipsets. In practice, chipsets through 4500MHD are supported with DRM and 3D using FreeBSD 9. The combination of these two changes in graphics driver code resulted in many Mac revisions being unable to upgrade to Mountain Lion, as their GPUs cannot be replaced.įor a while MacBook and MacBook Pro notebooks instead shipped with a far more powerful NVIDIA GeForce 9400M, and the 15" and 17" MacBook Pro notebooks shipped with an additional GeForce 9600GT supporting hybrid power to switch between GPUs.
Subsequently, OS X Mountain Lion dropped 32-bit kernel booting. No 64-bit drivers were offered in OS X Lion.
November 9's 10.6.2 update ships with 64-bit X3100 drivers.Īpple removed the 64-bit GMA X3100 drivers later, and thus affected Macs were forced back to the 32-bit kernel despite being 64-bit clean in terms of hardware and firmware.
This means that although the MacBooks with the X3100 have 64-bit capable processors and EFI, Mac OS X must load the 32-bit kernel to support the 32-bit X3100 drivers. Mac OS X 10.6 (Snow Leopard), which includes a new 64-bit kernel in addition to the 32-bit one, does not include 64-bit X3100 drivers. However, special modifications to the kext file must be made to enable Core Image and Quartz Extreme.Īlthough the new MacBook line no longer uses the X3100, Mac OS X 10.5 (Leopard) ships with drivers supporting it that require no modifications to the kext file. Late-release versions of Mac OS X 10.4 also support the GMA 900 due to its use in the Apple Developer Transition Kit, which was used in the PowerPC-to-Intel transition. Mac OS X 10.5 Leopard contains drivers for the GMA X3100, which were used in a recent revision of the MacBook range. It has been used in all Intel-based Mac minis (until the Mac Mini released on March 3, 2009). Mac OS X 10.4 supports the GMA 950, since it was used in previous revisions of the MacBook, MacMini, and 17-inch iMacs.
