macOS 10.14 Mojave on Unsupported Macs Thread

[ASentientBot]

I´d like to tie ends from the other side (OSX hackers kexts for MB 4,x for El Cap), so if you could PM me the prelinked kernel of one of your machines, that might help!

The OS X Hackers kexts for 10.11 should work in theory. They are 64-bit and El Capitan is pretty recent. Probably you need to bring over another kext that is a dependency. Did you try the following?
- correctly install them in /S*/L*/E* with fixed permissions
- disable SIP
- boot into single-user mode and run kextutil -t -v 6 /S*/L*/E*/IOUSBHostFamily.kext

What is the output of the command? This should help diagnose why it's not loading.

My graphic card is an Nvidia Geforce GT 120. I think I'm on HFS +. I'll try today to re-install the patch and let you know. I'll also check the number of my airport card to see if it's compatible or not. I have a 256 GB Samsung SSD and two back up HDD. 20 GB of ram. I use trim unable for the SSD. This computer has always worked very well, perfect for music production with what I use it for

It could be your gpu.
Others reported problems connected to the GT 120.

If you're using a GT120 in your system, you'll need to make sure that you manually select the "Legacy Video Card Patch" in the post-install tool, otherwise you won't get full graphics acceleration.

Will try your suggestions, thanks.

In the meantime I found that with the full framebuffer supported, at least Apple´s software-based OpenGL works (46 extensions loaded, v.4.1 of the shader and v.3 to 4.1 more or less supported) and launchpad and dock animations are quite ok (in comparison to Yosemite on the MB 4,1).
Forgot to mention earlier: Nightshift works like a charm on this machine!

Tried your kextutil command on a running MB 4,1 with the present kexts from the dosdude patcher (of course with sudo).
All relevant kexts already loaded, but interestingly, many mkext entries were "omitted", and no new mkext was built.
So far so interesting?

I´ll redo the kextutil outputs with kext from 10.11 and in single user mode, **promised** ;-)
Edit: USB/keyboard not running - how could I fire the kextutil command in single user mode? SSH in?

That’s so smooth. I would definitely use that myself. How come the framebuffer is supported but acceleration isn’t? Sorry but I’m that well versed in the graphical area.

For the framebuffer to be detected correctly and to be used, a relatively simple API/functionality has to be followed, which is also much more generic between different graphics card/chip manufacturers. The HW-acceleration is, on the other hand, not one monolithic function, but a complex set of different function calls that has to be managed between OS (kexts), the cards ROM (firmware) and higher driver and application layers (i.e. OpenGL). And most of the older kext have not been maintained since Snow Leo or Mountain Lion...

Using a similar configuration: same 4,1 2008 model, RAM & SSD.

1) On 10.14.2 Mojave, I tested a download from the App Store, "Tactical Monsters" and it downloaded and started fine. Not sure your Mojave version. Seems fine here.

2) Replaced the original wifi card some years ago with an Atheros 9380. Had to use a usb Wifi adaptor and update it before it would work with Mojave. There are similar wifi cards available on Amazon and eBay for about $12 that will drop right into the slot inside the laptop.

Good luck!

2) I replaced the non-recognized BCM 4321 AirPort card with a brand new Apple Broadcom 4322 AGN BCM94322MC card (eBay item 272528670442). Works flawlessly in my 17" Early 2008 MacBook Pro 4,1 2.6Ghz 6GB RAM 500GB SSD (model A1261). Connects to our WiFi network at 120Mbps down / 10Mbps up... exact same speed as Ethernet !!!

Make sure you haven't applied the legacy video driver patches because of your GT120 as those will destabilize the GTX660 drivers.

I can attest to this, the Legacy Video Drivers patch wreaked havoc on my GTX670 in my Mac Pro. Did a clean install without the Legacy Video Drivers patch and it works like a champ now.

 

[Innacity Man]

Your GT120 graphics card is not metal capable and will therefore not work well in Mojave. If you want to stick with Mojave a graphics card upgrade is really required. A GTX680 works very well. Otherwise I would suggest you return to High Sierra as that was working well for you.

In Dosdude page, it's written that all Nvidia cards in Mac Pro, work very well even if not metal.
[doublepost=1548133435][/doublepost]So, I reinstalled Mac OS and applied the patch again and everything works fine now. No graphic issues anymore, no crashes, my wifi back again and airport card recognized. I did it directly from the Mac Pro itself, and not the way I did it the first time, from my MacBook Pro on my MP's SSD in an external drive. So I'm sure this is the reason of all the issues I had. So I hope my experience will help people having the same issues.

 

[Scrotorr]

What changed in the 10.14.1/10.14.2 updates, or the updated version of the Mojave Patcher that gimped the 5770 almost completely? I'm using a Mac Pro 3,1 and if I do an install with the original patcher and the original retail release of 10.14 I can use the Legacy Graphics Patch and have a very snappy and usable system, but every time I've gone to 10.14.1 or 10.14.2 that goes out the window. I have done clean installs of each, I have tried to re-install the legacy video patch and rebuilt kext cache but nothing seems to work.

Any thoughts? I could do a re-install of the base version, but I'd prefer not to if I'm just missing something. Or I can toss my 8800 GT back in, but I lose a lot of 3d grunt with that little guy.

Thanks!

Thank you again, DosDude.

I just installed Mojave on yet another unsupported Mac in our household.

iMac 12,1 21.5" mid2011

Because it has an OEM AMD RadeonHD 6750M 512MB Graphics Card post-install there was a strange blue hue/color even to the sand dunes(ie absence of red) to the LCD screen that I could not work-a-round UNTIL.....

I used ResXtreme to decrease from a 10 to an 8 bit profile and all colors are now restored to normal/standard.

The Geekbench results = single core score of 3224 and multicore score is 8123 with 20GB of RAM

Thanks DosDude and all forum members for keeping this thread active & vital!

Is it even useable without gfx accelration?!

That is good news. The mp3.1 works well with Mojave and as you found the simplest way is to use dosdude1's installer. Yes, the GT 120 will work provided you install the legacy video card patch. As it is not a metal card you may come across some of the graphics anomalies that others have experienced on this thread. If you do decide to upgrade to a metal card (we have that luxury in the mp3.1) then you will have to do a fresh install to remove the legacy video patch because this causes problems with cards that can use Mojave's native video drivers. All the best.

May we get the first reports, how the update process to the just released 10.14.3 works?

Waiting for same ... :-D

 

[0403979]

@the.burn @LukeWorm Someone needs to test the 10.14.3 installer with the 1.2.3 patcher. If that works, the likelihood of the installing and the patching working is pretty high.

 

[flowsy]

Just used the Mojave Patcher on an El Capitan machine to download the newest Mojave build, but it downloaded High Sierra.

That's normal. The download key needs to be updated. No idea why it downloads High Sierra though... It should just download nothing I think.

 

[alphascorp]

Same for me, 10.13.6 downloaded instead of 10.14.3 using patcher 1.2.3

 

[telepati]

@telepati, As you may recall, I was having trouble getting into firmware update mode on my iMac8,1, I've just tried starting from an patched installer external drive, dismounted my internal SSD and was able to convert from HFS to APFS in Disk Utility. I was then going to install the software APFS patch but tried booting from the internal SSD and it started!! So I conclude that at some point in the past APFS ROM Patcher must have worked, perhaps iMac8,1 and 9,1 are always in firmware update mode or don't have the long tone?

Is there a simple way, I can check if the ROM has been patched correctly other than being able to boot an APFS volume?

Also does APFS ROM Patcher check if the ROM has already been patched?

If I am wrong probably @dosdude1 or other users will be correct me. As far as I know, if you patched correctly with APFS ROM patcher you will not see afps bootlog when you boot your mac.

 

[dosdude1]

Not necessarily, you have to make sure that you don't install the APFS patch when applying post-install patches to a machine with the APFS ROM Patch applied.
[doublepost=1548188938][/doublepost]The Patcher will be updated soon (if necessary) to ensure compatibility with 10.14.3.

 

[DaniloGeekDude]

Updated from 10.14.3 Beta 4 to 10.14.3 GM

Used OTA and @dosdude1's Mojave Patcher 1.2.3



Testing now.

 

[Flacko]

May we get the first reports, how the update process to the just released 10.14.3 works?

OTA update (1.75GB) on my MacBook air 4.2 seemed to go without a hitch. Used patcher 1.2.3 to fix audio but no other problems have yet to surface.

 

[ASentientBot]

I believe it is less a matter of a "key" and more a matter of which file index in the software catalog to download. If you do the download manually, you'll see that the catalog is just a long list of packages. However, I don't know why the patcher doesn't just check the version number that's readily available in InstallAssistantAuto.smd. I believe I could make a more reliable auto-downloader quite easily, and dosdude1 is clearly more experienced than I am. Am I missing some weird caveat?

So basically "if it works, then it will probably work"? lol

OTA 10.14.3 final on MB Pro 5,2 works as previously, after re-patching with v1.2.3
