work integrate gem, kms adding support i-series integrated graphics, improving support earlier chipsets. in practice, chipsets through 4500mhd supported drm, 3d using freebsd 9. combination of these 2 changes in graphics driver code resulted in many mac revisions being unable upgrade mountain lion, gpus cannot replaced.įor while macbook, macbook pro notebooks instead shipped far more powerful nvidia geforce 9400m,, 15, 17 macbook pro notebooks shipped additional geforce 9600gt supporting hybrid power switch between gpus. subsequently, os x mountain lion dropped 32-bit kernel booting. november 9 s 10.6.2 update ships 64-bit x3100 drivers.Īpple removed 64-bit gma x3100 drivers later,, affected macs forced 32-bit kernel despite being 64-bit clean in terms of hardware, firmware.

means although macbooks x3100 have 64-bit capable processors, efi, mac os x must load 32-bit kernel support 32-bit x3100 drivers. mac os x 10.6 (snow leopard), includes new 64-bit kernel in addition 32-bit one, not include 64-bit x3100 drivers. however, special modifications kext file must made enable core image, quartz extreme.Īlthough new macbook line no longer uses x3100, mac os x 10.5 (leopard) ships drivers supporting require no modifications kext file. Late-release versions of mac os x 10.4 support gma 900 due use in apple developer transition kit, used in powerpc-to-intel transition. mac os x 10.5 leopard contains drivers gma x3100, used in recent revision of macbook range. has been used in intel-based mac minis (until mac mini released on march 3, 2009).
Mac os x 10.4 supports gma 950, since used in previous revisions of macbook, macmini,, 17-inch imacs.
