Did you install the correct patches on the patch updater? I have a hunch that you forgot to install a necescery patch.

I suggest doing a reinstall of Mojave, just be 110% sure you select all of the patches you can when you first initialize Mojave.

Update (11/03/2018)

I’m pretty sure you forgot to select the “Legacy Audio Patch” to be installed on this step.

Reinstall Mojave and be sure to do it the right way. The creator of this patch has instructions on how to do this properly below.

could be that too...

i was installing it in my MB i just updated it from App Store, what patch you talking about please?

@ayoub_tl You certainly did not just “update it from the App Store” because this is an unsupported machine. I’ll bet my reputation on this site that you used the Mojave Patch Tool or something of the like. Check my updated answer.

thank you so much, after i updated, i use this tool only for patch i didn't have to reinstall mojavi, and am still have the new update on my MB.


Basically you can’t use the auto update function or manually update via Apple as the update installer will wipe out your required drivers for your system. You need to stick with DosDude moving forward.

While I sympathize with you wanting to run the latest and greatest MacOS there is a point in time you need to bite your tongue and just sigh ;-{

The highest your system will support officially is High Sierra and its best just to stick with it.

It’s truely a shame that Mojave requires METAL capable GPUs, effectively making non-capable GPUs a giant nail in the coffin for the Macs they are soldered onto.

While these “patch tools” are great in the moment when you first install them, there are major headaches when it comes to updating Mojave as an OS because every time Apple updates Mojave, these types of loopholes get patched requiring you completely re-install them.


The simple answer - You should have not have updated to Mojave, there is a reason Apple does not include them on the update list.

What you can do - Find a way to uninstall Mojave back to whatever OS you were running before.

Can’t find out how to Uninstall?- Use an external speaker, it is the best you can do.
