ATI 5450 on MACPRO with 10.11.6 problem

Question

Hello, I cannot run my ATI HD5450 on MACPRO 1,1 with 10.11.6

It run ok under 10.7 lion with the 68F91002 kext modify manually on ATI5000controller and the other ATIRADEONX3000.

 

I tried to do the same on 10.11.6 but nothing. I can see only black screen.

Now I have both video card on the MacPro and it works with GT7300 but in system report It says no kext loaded for the other video card....



Here the report:

I loaded both them manually but how can I load them at the boot? I think this is the problem....

Now I'm not use clover boot loader, I'm just use the original boot loader to boot 10.5/ 10.7/ 10.11/ win7

 

thanks

Michele

When you edit a vanilla kext, you systematically lose its code signature, it is why you have that 'has invalid signature' error. I know there a terminal command to code sign a kext but do not remember anymore, sorry. Research for google, I guess.

 

OTOH, I do not remember anymore but I think you need the boot flag 'kext-dev-mode=1' under ElCapitan which allows you to boot with those 'invalid signature' kexts.

 

But Clover developers made the thing more better... they integrated that boot flag into the nvram.plist, so you need no more that boot flag. 

 

So, all you have to do it is to update your clover version, if you're still using it.
