[Guide] Enabling ATI Radeon HD 5450

[EdmundF]

The fun is short lived, after the 10.13.3 Supplemental Update today the youtube movies don't play very good anymore.
The video memory is still displayed right with 1 Gig but video performance is bad.
On the bright side, "maps" is still working.

Thanks! I have pretty much the same config.plist and have installed the modified kexts - still not the same results.

Strange, after a reboot everything is well here, even after that supplemental update.

Did you have any SSDT or DSDT patches for the graphics? Or just edits in config.plist and injection of two modified kexts? Do you happen to have your kexts handy by any chance?

I briefly read about that DSDT but I don't even know what it is so I guess I haven't done anything like that.
Here is my zipped clover that I just ( now ) took from my Hard drive from which I am booting.
It contains the kexts I use no idea if they are modified.

I will try this and see what I get back. I have noticed one thing though, none of my ATI/AMD Kexts load at all. They either have signature error or they simply don’t load. My AMD3000X loads fine every now and again but 5000Controller kext never loads. Is there a way to over ride system checks and force load the Kexts?

 

[EdmundF]

Sorry I don't know. I build my first ever Hackintosh last year and just followed what I am reading here.
As a matter of fact I don't know how to find out if kexts are loaded or not, if you tell me how, I will check if my 5000Controller kext is loaded.

Two ways to do this. Go to Apple logo > About this Mac > System Report > Software on left panel > Extensions. Scroll through the list.

Or in terminal - sudo kextstat |grep AMD

OK thanks, they are both loaded here

Thanks for checking. Mine hasn't worked. Strangely enough I even reverted back to Sierra install (fresh) and can't get my graphics to work. It used to work all the way upto 10.13 but now it just won't work. It was as simple as Clover injection in 10.12.x but now that doesn't work. I wish there was a patch that worked for everyone with this card.
