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 and later dropped support for non SSE4.2-capable 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 and later support 64bit apps only.

 

For Hackintoshing purposes:

  • Netburst/revived P6/original Core 32bit platforms (Pentium 4/D/M, Yonah, etc.) are natively supported from Tiger 10.4.4/10.4.5 to Snow Leopard 10.6.8.
  • Netburst and Core2 64bit platforms (Pentium 4/D, Conroe/Merom, Penryn/Wolfdale, etc.) are natively supported from Tiger 10.4.7/10.4.8.
  • 1st gen Nehalem platforms (Lynnfield, Clarkdale/Arrandale, etc.) are natively supported from Snow Leopard 10.6.2/10.6.3.
  • 2nd gen Sandy Bridge platforms are natively supported from Snow Leopard 10.6.6.
  • 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.
