Probably bluetooth keyboard unpaired at power-on, or batteries in discharge, try with a usb keyboard to hold "option-alt" at startup, then boot again from USB Mojave Installer , launch Terminal from there and type:
nvram boot-args="-no_compat_check"
reboot

Thank you! That worked. Thought I’d bricked my iMac for a second. Good thing I had a wired keyboard lying around too.

Now the only issue is the weird inverted colors! (See pic). Is there a solution for this or is Mojave broken until someone figures out how to enable Metal and acceleration on AMD cards?

What a shame...

I’m having an issue trying to update my 2008 iMac to Mojave. It’s currently on El Capitan with 3GB RAM and 256GB SSD. I successfully created my bootable Mojave USB, but when I hold option on the startup of my iMac and select the USB, it just sits at the white screen with Apple logo. I left it to run overnight, but when I checked this morning it was still there at the same screen, no progress bar or anything. The iMac can boot fine into its SSD, however. Any ideas? Do I need to upgrade to Sierra -> High Sierra -> Mojave?

Out of curiosity has anyone had success of upgrading your Mojave without a complete clean install? Everytime I tried as Mojave was being installed it got to only a few minutes left and it rebooted. So I shutdown and booted from the USB stick and applied the patch. On reboot I got the circle with the line. Maybe I am doing something wrong, if so pleae let me know for next time.

there is but this will make your imac a bit slower in graphics animations, go inside System/Library/Extensions and put into the trash this file: AMDRadeonX3000.kext then reboot

Yes I installed from an existing High Sierra installation. Had the same issue as you. Read back a few posts about the Terminal “nvram” solution. Worked for me. Now just those colors...

Thanks again, that fixed the colors. But like you said, sloooow animations and no transparency. Feels like I’m back in 2011 :p

Oh well, I guess Apple has won this round. Hopefully @dosdude1 or another genius here figures out how to get AMD cards working with Mojave - I mean come on, Intel integrated graphics from 2012 work fine, but not a dedicated 1GB card on the top-spec 2011 iMac?

Back to High Sierra for now on my production machines, while the lowly 2012 i5 mini gets to enjoy Mojave in all its glory ;)

Thanks again to all of you guys - great community this! Will check in from time to time to see if there’s any hope for the older iMacs.

You have an AMD video card. The Mojave patching effort here hasn't figured out how to get AMD video acceleration working on all cards.

Ok I got that, but I didn't understand it meant that the whole interface would be sluggish :(
Is there a way to disable video accelaration on those iMac ?

I have the same issue on my iMac, but only when I unplug my second monitor... Weird...

Guys, help! Just ran the patched Mojave installer on my 2011 iMac and on reboot I get a click click and a grey screen with a no entry sign. Holding Alt to enable startup disk switching doesn’t work either. No MacOS startup sound either.

What happened!?
Click to expand...

Once the initial installation completes, you must boot from the installation USB once again and install the appropriate post install patches for your iMac. It should then boot normally, though it may take longer.

To disable acceleration you have to unload the AMD FB kext, a quick way is to check if in your System/Library/Extensions there is this kext AMDRadeonX3000.kext if is there simply drag into the trash and reboot.

Thanks didn't know it was applying to me too !

It is indeed much better after removing this kext...
I m just curious about the impact globally... In which situation does it make a difference to use the GPU (knowing that this particular one is crap :) )

I have a question in regard to Mojave itself. On my Primary Mac 2017 iMac software update via app store icon doesn't work as it did in Beta. When I click UPDATE it does nothing. It doesn't even say No Updates available. But on my Non supported Mojave it is different. I don't know why there is a difference. Below are screen shots of both. If Software update for applications is now in System Preferences why does the App Store still have the update in it.

I didn't notice this in beta ~4 when I found the fix but you're 100% right. It's super laggy now and I don't know why. I'll look into it. Seems related to a Console error about "CMIOHardware". Perhaps something else needs to be replaced from HS too. Sorry for not seeing this before, I don't use iSight camera much at all.

Edit: Looks like the root cause may be CoreMediaIO.framework but I don't particularly want to risk replacing that from HS. I'll mess around with it when I get home from school, maybe. But a fix might not be a simple kext replacement this time.

Ok man. I noticed the problem because i always use skype and facetime, so it's very important for me. Thank you so much!

The GTX 980 should work out of the box.

That sounds so completely wrong that I tried it and had to hard restart my computer because my Cinema Display wasn’t recognized by either GPU even after power cycling.

The 980 should be a Kepler card and should work with Apple's Nvidia system drivers.
Click to expand...

Definitely not, I can confirm that. Apple never sold one, and mine isn’t flashed, so I’ve always had to use the nVidia web driver.

Also, my Wi-Fi works fine, it just doesn’t automatically connect to any network. I have to manually input it every time I boot. Should I use the Wi-Fi patch?

On my 10,1 iMac with SSD, I am getting errors in Disk Utility, both in recovery (started from my USB stick because the normal recovery partition doesn't work yet with @dosdude1 's tool?) and am getting errors.

Is this related to the patching?
I noticed that startup of Mojave takes much longer than with High Sierra, so I was looking into if something might be wrong, somewhere...

I'm running Mojave patcher on an early 2011 13 inch MacBook Pro. It is running Mojave version 10.14 Beta (18A384a). Yesterday Mojave was updated to the final version out of beta but I am not getting the update. Is there something I have to do to get the final version of Mojave?

yes you can - on an unsupported Mac running beta Mojave - the download button in the App Store redirects to the system settings update panel and downloads the installer.
You cannot run the unpatched installer, but create a patched USB stick

Well that's new(s), something that's happened since we started installing the betas -- and something I've never tried, I guess, since attempting to install the first beta! Thanks for the correction.
