/!\ Min. requirements for OS X/macOS

Recommended Posts

Last update: 31 Mar 2020

 

Questions keep resurfacing, so let's try to clarify things again:

 

Essential basics:

  • Lion requires a 64bit Core2Duo minimum even though it may have to run in 32bit kernel mode (eg: for Intel GMA platforms).
  • From Mountain Lion, OS X runs a 64bit kernel only. 32bit kernel mode is abandoned, hence the drop of support for older GPUs for which only 32bit fully functional drivers are available (e.g.: Intel GMA 950/GMA X3100, nVidia GeForce 7xxx and derivatives).
  • Sierra and later require SSE4-capable CPUs (SSE4 instructions set introduced in Penryn family C2D/C2Q/Xeon CPUs).
  • Mojave dropped support for C2D/C2Q platforms (workaround exists).
  • Mojave and later requires a Metal-compatible card (Kepler-only for nVidia (lack of Web Driver oblige), GCN1.0 and later for AMD).
  • Mojave is last macOS version to support 32bit apps.
  • Catalina dropped support for 32bit apps; from now on, it's 64bit apps only.

 

For Hackintoshing purposes:

  • 1st gen Westmere (Arrandale/Clarkdale Core "i") platforms are natively supported from Snow Leopard 10.6.3 + updated kernel 10.3.1
  • 2nd gen Sandy Bridge platforms are natively supported from Snow Leopard 10.6.6-10.6.8
  • 3rd gen Ivy Bridge platforms are natively supported from Lion 10.7.5
  • 4th gen Haswell platforms are natively supported from Mountain Lion 10.8.5
  • 5th gen Broadwell platforms are natively supported from Yosemite 10.10.2/10.10.3
  • 6th gen Skylake platforms are natively supported from El Capitan 10.11.4
  • 7th gen Kaby Lake platforms are natively supported from Sierra 10.12.6
  • 8th gen Kaby Lake Refresh & Coffee Lake platforms are natively supported from High Sierra 10.13/10.13.1. Fully supported in 10.13.6. 8th gen Amber Lake Y (UHD617) platforms are supported from 10.14.1.
  • 9th gen Coffee Lake Refresh and Whiskey Lake platforms are natively supported from Mojave 10.14.4/10.14.5
  • 10th gen Ice Lake & Comet Lake platforms are natively supported from Catalina 10.15.3
