macOS 10.14 Mojave on Unsupported Macs Thread

[mdgm]

I might try OCLP using Mojave sometime. I see there is a Mojave-Catalina branch including the TS2 patch so putting the TS2 acceleration patch on should be possible.

Hi,

cannot confirm myself this is working without any hacks any longer - but I assume it is from the messages we have seen here recently. Only the update process in Catalina is broken in a way that you need further hacks to get it done.

Left the @dosdude1 route nearly a year ago and manage all my systems using OpenCore (in particular OCLP, which does not officially support Mojave or Catalina, but works beautifully), even with Mojava and Catalina. But I am the lucky guy to be able to change the GPU with a metal one in all my systems (iMacs, only) which makes the systems de facto 100% compatible. The minor details like WiFi/BT etc can be handled by OpenCore injection instead of root file system patching.

Nevertheless I would migrate to APFS - what was the reason to avoid this? When moving over to Catalina (if you plan this) you will face this the 32/64bit cut and I would advice the backup/restore route ignoring the programs and libs you have collected the last 10 years (a lot of may be not 64bit compatible at all) and reinstalling them.

Sometimes one has to clear the attic…

Thanks. I wiped and converted my MacBook 5,1 partition to apfs, and installed Mojave from scratch with the USB installer. Repatched using the dosdudebpatcher tool and then Updates were available in software update panel

Installed them and had to repatch again, Everything was working great but then installed Google chrome which has all my necessary shortcuts but it’s instantly started doing the blank screen thing and freezing, (gpu hardware acceleration problem?) so inevitably moving on to tackle my next problem…

b.tw, Is there a known way of turning off chrome’s hardware acceleration without opening chrome to do it , because it’s non functional after ‘starting’?

I get the Chrome blank screen and freeze thing sometimes after Chrome updates. After a few Force Quits and re-launches it fixes itself. Never had it where it didn't fix itself. I'm using Chrome right now.

Hello -- Could someone in the know answer a quick question for me please?

I'm running Mojave 10.14.6 on a Mac Pro 3,1 which I installed using dosdude's tools a few years ago. I haven't kept track of this thread regarding Security Updates, etc.

My question is: Can I safely just click "Install Now" for the Safari 14 and Supplemental Update listed in my Software Update Window?

In my distant memory I seem to recall that installing such updates the traditional way were not safe, so I hesitate to install these.

Thanks in advance to anyone who can let me know! Cheers! RD

As always – no guarantee. But you should be fine with it, as long as you re-apply the Mojave Patcher after the installation ...

You can safely update but after every system update you need to stick in the @dosdude1 patcher usb and run the post install patch.

 

[spiritguitar]

Thanks for your reply coasterOneEightThree and Dilli. I'll give it a try and report back, unless I get lost in no man's land. ?️

Update: I just installed the Supplemental Update and Safari 14 with no problem. I tried to boot from my Patcher USB but my Mac booted from my regular startup drive instead. I ran the Patch Updater which stated I'm Up To Date, so I think I may be okay - everything seems to be running normally. ?Thanks again for your comments -- cheers!

If you had used SilentKnight to launch the updates, you would have also received the MRT and X-Protect updates, as well. Still need to boot into USB and re-install patches, in every event. https://eclecticlightdotcom.files.wordpress.com/2020/11/silentknight115.zip ?

 

[spiritguitar]

Thank you K two...I tried again to run Post Install from my Patcher USB and this time I was successful. I also checked out SilentKnight and updated MRT and X-Protect successfully. So thanks again for your comments. Cheers!

Hallo everybody

I upgraded my MP5.1 a couple of years ago and therefore I am on 144.0.0.0, but following an issue with the boot disk (the iPhone backup hogging it to the point of leaving not enough space, could not find how to free this space even after deleting the backup files) I tried to boot from another SSD I had installed Mojave on and… I just get a dark screen. The noises seem to indicate it is starting up, but I see nothing.

After a few attempts (PRAM, Smc) I managed to make it work by putting back the Original 4870 video card, which not being metal would not be supposed to work, right? Instead, it produces artifacts and is slow, but works.

I looked in these threads and the only similar issue I found was with a kext I verified I don’t have. I only see the Apple installed kext plus little snitch and the ntfs ones.

Any idea on what should I do to make it work again with the metal video card?

Thanks in advance
Maurizio

Suggest you backup your data and fresh install Mojave on your ssd. All your glitches should disappear.

 

[subfly]

Thanks, I forgot to say I tried that, but I am in a catch 22, I have an install usb but when I launch the install it says it cannot install without a Metal card, and with that card I see nothing

Your MacPro is natively supported with Mojave, but your 4870 GPU needs a legacy video patch from the patcher. I would try to buy a metal GPU to get around this.

Note: Lately even Big Sur got a legacy patch for your type of card. To install Mojave without a metal card you need the dosdude1 patcher to patch the Apple USB installer as documented here.

Please mention your machine type in your signature with the specs so that people can give you response related to your issue.
Follow what @Ausdauersportler has mentioned above

Did you try the post install patch after installation.?

Sorry

Here is the hardware screen.I have a Metal card, which I used for two years with no problem, a Radeon RX 560 Aero itx 4G. The SSD which I tried to launch is a Samsung 860 QVO and I have a Calstart PXS4 and a 1242 USB3 cards on the PCI bus

Thanks
Maurizio

 

[subfly]

About the patch, I don’t remember since I did the installation quite some time ago, how could I see it? Is it visible from the firmware versions in the screen I posted?

Hope it helps.

Thanks, I tried and it says the machine is natively supported… no need to apply it

I assume the AMD RX560 has not been flashed to offer an EFI boot screen.

Using your AMD RX560 card you need to use OpenCore to give you a boot picker and boot screen back. You can either check this thread, or this one, or use this OCLP tool (the tool offers automatically what you have to download and install manually from the first thread and configure completely manually using the guide on the second one).

Do not shoot me for offering more than one solution. Using OpenCore enables the hardware acceleration off you RX560 at the same time (native 4K H,264/265 and 4K HEVC).

Edit:
Technically all three solutions are doing more or less (cum grano salis) the same thing using the very same OpenCore tool. Historically the there projects started at different point in times with different goals. The latest tool offers the most out out the box and is planned to install Big Sur - not just to offer a boot screen and enable hardware acceleration pin your type of system.

 

[subfly]

If by boot screen you mean the progress bar at startup, it did it out of the box. What puzzles me is why it changed behavior

 

[subfly]

I tried to set as startup disks a USB key amd another ssd with mojave and then swap the video card, but the screen still says no signal. I tried booting with R, alt-R, alt, D, reset smc and PRAM, stlil no signal.
What is that “enables” a card? Even if it weren’t flashed and not showing the boot screen it would still visualise after that. In my case the boot screen worked out of the box, so there is nothing to revert to. It did the same before goong through the procedure to move to mojave, but how can it go back to that after the upgrade, and Mojave working with the old card???

Did you check all the ports of your card? How is your display connected, connector type and do you use converters like miniDP to VGA or something similar insane. Sometimes a new macOS version disables some ports, especially on systems like yours with non apple hardware.

Sorry, your description is somehow confusing. I lost track which GPU, which macOS version, which OC version (if any). Please provide a better and more detailed description of your complete setup.

OCLP should allow you to install Mojave unpatched. Which BT & WiFi card do you have installed and did you check out the MacPro3,1 specific threads? You cannot be the only user doing exactly this on this machine.

My machine is a 4.1 upgraded to 5.1 years ago, then updated with 144.0.0.0 when I installed Mojave and a 3.46 GHz Westmere. To do that I bought an RX 560 Metal card from MSI, which worked out of the box with the boot screen.

I connected it to a NEC 2610 WUXI by DVI, but I tried 5 minutes ago another screen through HDMI, no signal also on that screen.

I just noticed that to shut down it is enough to push quickly the start button, so it is not booting at all, (I thought it was booting but not showing the screen) even though I hear the HDs turning on and seeking. It might therefore not be a card issue but a boot issue, if I don’t misread the facts, even though in that case the screen should work but I would expect to see a question mark or similar.

I took out all other PCI card, now I will try moving the video card on another slot and taking out all HDs but one.

 

[subfly]

I took lut all HDs pne by one, nothing changed. However, I realised I cannot reset the PRAM, no matter how long I keep alt-command-P-R nothing happens. I used both front USBs to connect the keyboard and in both cases the geen light on the Cpas hold flashes briefly only once. I an now disconnecting all other USB peripherals.

 

[subfly]

No change, while with everything connected and the old card everything works fine. And all this because I tried to change startup disk…
