    In this thread, advancements in running macOS 10.14 (Mojave) on unsupported systems will be discussed.​

    June 6: There is still an OpenGL renderer, it's just intentionally disabled. we're trying to enable it.

    June 7: The crash on MacPro3,1 is not caused by lack of SSE4.2 (because Mojave works on Hackintosh core 2 duos). We think it's caused by IOUSBFamily.

    June 8: With replaced IOAcceleratorFamily2.kext from 10.13.5, all of the required AMD and Intel kexts can be loaded! Thanks to Czo for finding this.

    June 18 (parrotgeek1): I haven't had time to work on this for a while, sorry. The 2 people we asked for help seem to think that this project is stupid and unlikely to work and won't help us. There is some good news though, we got the Nvidia kexts to load. But there is still no acceleration.

    June 19 (dosdude1): After experimenting a bit trying to resolve the USB issues on MCP79/89 and older systems (anything pre Nehalem), I have come to the conclusion that Apple must have changed something major. Adding AppleUSBOHCI and AppleUSBOHCIPCI kexts from 10.13 causes an instant kernel panic on the older systems. Replacing EHCI and EHCIPCI kexts with 10.13 ones causes an instant kernel panic on all machines.

    AMD GPUs won't work on MacPro3,1/Xserve2,1 until there is a SSE4.2 emulator, for technical reasons.

    A possibility for some computers is a Thunderbolt external GPU.
    This needs to be investigated more, and requires kext patches.

    These facts leave the compatibility list as theoretically:

    • Xserve 2008 (if we can fix the crash; Nvidia GPUs only until SSE4.2 emulator made)
    • Xserve 2009
    • Mac Pro 2008 (if we can fix the crash; Nvidia GPUs only until SSE4.2 emulator made)
    • Mac Pro 2009
    • iMac Mid-Late 2011 (Thunderbolt GPU only)
    • MacBook Air Mid 2011
    • MacBook Pro i5/i7 Mid 2010-Late 2011 (only the ones with HD Graphics or Thunderbolt GPU, 320M/330M won't work, see above for why)
    • Mac Mini Mid 2011 (only the ones with HD Graphics, or Thunderbolt GPU, not AMD; see above for why)
    The following unsupported models are Thunderbolt capable:
    • MacBook Pro (Early/Late 2011)
    • MacBook Air (Mid 2011)
    • Mac mini (Mid 2011)
    • iMac (Mid 2011)
    Yet a third possibility is to upgrade the MXM slot GPU on 2008-2011 (and maybe 2007 with an upgraded CPU?) iMacs. This has not been investigated yet.

    Any news yet on which Macs are supported? I have been unable to find information about this.

    As of yet, the systems officially supported in 10.14 are unknown, and the download is not yet available in my Dev portal. I will update the thread as updates are received.

    “macOS Mojave will be available this fall as a free software update for Macs introduced in mid-2012 or later, plus 2010 and 2012 Mac Pro models with recommended Metal-capable graphics cards.”

    unfortunately my core i7 late 2011 Macbook Pro is not supported anymore...

    Wonder why they would drop support for the 2011 iMac.

    Now to find out what Metal cards are supported on the Mac Pros. 4,1 to 5,1 conversions should have no problem installing with a proper card. I'm assuming most AMD RX cards are fine, but what about nVidia?

    I guess I'll be needing your help for my 2010 iMac.

    Not that I really care that much though, since I'm only using it as an external monitor these days, for my 2017 iMac. :D

    It's seems to me, that most unsupported macs need an updated GPU. So, iMacs with upgraded GPU and Mac Pro's can be supported unofficially. But all of the available cards with MXM format are can't control the brightness of the iMac screen and can't show the boot screen.

    This will be harder since it seems like the entire OS is metal based.. and emulating that kind of stuff in software makes for a crappy experience

    Seems like the entire OS is on Metal so 2012 or newer officially.

    indeed, i think tools that dosdude1 created like macOS High Sierra Patcher Tool for Unsupported Macs wil maybay get a hard time on this one..
    Metal hardware is possibly required, but we will see...

    Yeah, I think I'm happy enough keeping my iMac11,3 & MacBook5,1 & MacBookPro5,5 on 10.13 High Sierra, since the OS supports the new image formats and APFS. And I expect we'll have modern browser support until 2022.

    Now it appears my Early 2011 17" MacBook Pro will be in need of a patch to run the latest version of MacOS. To add insult to injury, Apple no longer makes a comparable product worth buying (the 17" MacBook Pro was discontinued in 2012, and Apple has never introduced a 17" with Retina since).

    This might be much harder to crack graphics wise. I spent way too much time trying to get OpenGL support on the older machines during the ML/MacPostFactor/macOS Extractor days and still couldn't get past the WindowServer crashes.

    I really hope iTunes will get updates for a long time on High Sierra, and of course internet browsers...

    The update period is usually three years for Safari + general security updates and four years for iTunes (minus one year as High Sierra was released last fall). Third-party browsers such as Chrome are generally supported for twice as long as Safari.

    So there's still some time to go before High Sierra is no longer viable, but missing out on features like dark mode on older Macs is seriously disappointing nonetheless. Dark mode should have been added years ago in my opinion.
