Ok so erased my partition and used 1b4 patcher and now have Mojave running although graphics still glitchy with this MacPro 3.1 using an Nvidia GeForce GT 120 512Mb card, any thoughts from anyone.
 
I am currently running High Sierra on my MacBookPro 17" late 2008 with DosDude's patchers

MB166LL/A Model A1261 (EMC2199) MacBookPro4,1 2.5 Ghz Core2Duo(T9300) GeForce 8600M GT

While it doesn't look good is there any chance Mojave will eventually run on my machine? (computer specs in the link below)

[doublepost=1531168302][/doublepost]Should I still wait or give the Mojave install a try?

I would assume you’ll have as much success as Macs containing the 320m as they are both Tesla architecture and use the same kexts... framebuffer support, but no full acceleration. That being said, progress is not made without attempts, so feel free to try and report back with your results.
 
On my iMac 9.1 I got it to install with dosdude's patcher but as soon as I logged in and entered my password the screen went black and rebooted Thank everyone for all the hard work !!!!!!!!!!
 
That would be "Patch Updater" you're referring to, and I haven't implemented that for Mojave yet. It will most likely be included in the next release of the tool, though.
Ahh ok, as I am running a Mac Pro 3.1 should I have run the legacy Nvidia patch I have a GT 120 512mb graphics card.

Except that stuff is a lot more expensive, and for that 5% perf. gain, not really worth it.

800 MHz RAM is pretty cheap these days. It’s closer to an 8.34% performance gain at minimum.

Maybe we should start a Mac Pro 3,1 Hotrod thread, list specs of hardware used and benchmarks. Fast and the Furious Mac Pro 2008s

Thanks dosdude1 and others who made this possible.
Now working fine on MacPro 3,1 with boot rom flashed for APFS support. The only thing I can see that is NOT working is Bluetooth, which is a little odd b/c this 3,1 has an upgraded BT4LE/wifi card from a 2014 iMac and the wifi side of the card is working fine.
The GTX680 shows up as normal and no screen tearing or issues that I can see so far. iCloud in Messages is working as is email.
I'll play a bit more and report back what I see if anything.
I think the S/H value of Mac-flashed EVGA GTX 680 cards will rise!

[doublepost=1531174458][/doublepost]When we hear back from W1SS (?) about NVMe boot support for his ordered Highpoint PCIe card I might go all-in on the NVMe modified boot rom too.

Has anybody tried this yet? If not, I will.

Edit: I see from this page that this is a patched file for Fermi architecture GPUs? What modifications have been made to it and for what purpose?

Tried that CoreDisplay unix exe and still have same behavior LoginUI OK, desktop KO.

I have done few other attempts:

- Used 10.12.6 Nvidia Tesla kext, got same behavior again unless during verbose I catch a line "can't load com.apple.driver.AGPM"
I guess AGPM would deal with AppleGraphicsPowerManagement.kext

Anyway no significant progress at all.


My last panic report (using HS kexts) doesn't told much (this occurs with QE/CI right after reached desktop) :

panic(cpu 0 caller 0xffffff8018bb8053): "kfree: size 18446743522275614728 > kalloc_largest_allocated 10551296"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-4903.200.249/osfmk/kern/kalloc.c:752

I think will concentrate again on PrivateFrameworks's IOAccelerator.

I encourage anyone maybe to repeat also same attempts, could happen something escapes me.

W1SS, has the HighPoint card arrived yet and have you tried it with NVMe boot rom patch?
Also, what made you choose that card? Is there a required chipset or could a lower-cost card be supported?

Thanks. I'll wait until I hear what happens when you get your card installed!
 
No, as it will cause a kernel panic on login. As of now, it only works well on Intel HD Graphics.

On my MacMini with Intel HD Graphics, system is running great thanx to your patch. But I do have some graphics issue in the new apps Apple
has converted from iOS to MacOS such as News and Home, black boxes appear instead of certain icons as seen in picture. Any ideas of cause?

Any indication if a Sapphire Nitro RX 460 might work again? I was never able to get it to work in High Sierra, but in Sierra it seems to be flagged as metal capable. Thanks again to you and others who have kept my 3,1 humming along!
 
Just to report that using the latest magical patch tool of dosdude1. I have been able to install Mojave 10.14 Beta (18A326g) in a Mac Pro 3,1. the process was very simple. Just like High Sierra (this is the link to the install process in case someone reading is lost http://dosdude1.com/sierrapatch.html) So far I haven't noticed any display glitches. Everything seems to be working just fine like high sierra. My graphics card is a NVIDIA Quadro K4200. (by the way I'm writing this post using Mojave, the screenshot tool have many new options built in) Thanks to dosdude1 and everyone else to make this possible and keep on proving Apple that planned obsolescence is not the right way, is the machine still capable there is no reason to put it out of the supported list. Something else that I have notice is that the system seems to be more power efficient. As now the Mac Pro is idling at 152 Watts. In High Sierra it idle at 200 Watts. So still good news for our pockets!... Please pardon my English :)

Since High Sierra, AMD drivers for GCN cards (7xxx, R9-2, R9-3, RX cards) needs SSE4.2, that MacPro 2008 Xeons do not have.

Edit: forgot High.

I ran my flashed R9-280x card in High Sierra on my MP 3,1 for quite a long while but did have issues with red screens in Preview and the inability to sleep, which is why I removed it. These issues due to the lack of SSE4.2? I'm going to try the card again in the 3,1 under Mojave beta soon.
