Yeah, tried that one too (probably found the same blog post). Unplugging and re-plugging the display adds no extra options to the refresh rate menu.

Yes. I verified the display chain by installing Windows 11 to an external SSD and booting that on my Hack. With the exact same hardware, same DP cable, same display, I immediately got 2160p@144Hz (verified both from the Windows side and via the display’s OSD). I tried an HDMI cable (also...

Yes, holding down Option when selecting “Scaled” shows the refresh rate menu (although the refresh rate menu is actually always shown), it just doesn’t offer any options above 60Hz. Well, time to investigate the Thunderbolt route I suppose.

So I finally received, almost a year+ after promised delivery, the EVE Spectrum 4K crowdfunded monitor. Overall I’m reasonably happy with it, it’s a nice 27” 4K IPS screen that is perfectly usable with a scaled 5K display mode for day to day use (I’m not doing anything that requires pixel...

I was wondering if this has to do with my GeForce GTX 1080 still being IN my system (though I wouldn’t think so). I did try disabling my Set PEGP to GFX0 patch in Clover in case that was interfering but it didn’t seem to fix the issue. I’ll try the “disable-external-gpu” patch.

That’s the value set in the BIOS, right? According to my BIOS it’s 128MB. Should it be set to something else (it seems it can go as low as 32MB and as high as 1024MB)? Should the DVMT Total Graphics RAM be set to MAX?

So I decided to give this a shot in order to load up the Mojave Beta 4 on an external drive on my Hack. I did make it through the installer by selecting the only 3-connector Desktop Coffee Lake ig-platform-id and it's showing up in About This Mac as the Intel UHD Graphics 630 1536MB, however I'm...

APFS is not mandatory, but it is recommended on SSDs. Just make sure you have the apfs.efi driver in your Clover installation before conversion, or you will have A Bad Time™.

So after mistakenly attempting to put the dummy EH creation and USBX patches together in the SSDT-UIAC file, I broke each out into separate SSDT patches (SSDT-EC and SSDT-USBX). However, now that I re-read your post 1, it seems I can put the USBX part in as a section of UIAC. I’m guessing that...

Yes, edited my post; I had meant to say iMac18,3. Actually realized I had access to a legit iMac18,3 from which I could dump an IOReg; it reveals that its values are the same as those for the iMac17,1. So, for my machine (which has no EC to rename), I need to: create a fake EC, then provide the...

RehabMan, having skimmed through this thread after you linked me here from the USBInjectAll thread, is there a source for a correct iMac18,3 USB power property injection to add to my SSDT-UIAC, as that is the SMBIOS definition I'm using? Or is the iMac17,1 one similar enough to use as a starting...

PR files attached.

So, I eliminated an internal USB2 header (2 ports), two apparently-unused USB3 "ports" with the same numbers as that internal USB2 header (2 ports), two rear panel USB2 ports (2 ports), an internal SS+HS port that was entirely unused when I plugged stuff into every available external port) (2...

You don't necessarily need to update Clover (though it probably can't hurt—make sure to add the HFSPlus-64 driver as it's no longer installed by default in new Clover versions, if you need to boot HFS+-formatted volumes). What you might need to update is your USB port limit patch, if you're...

So, if after doing an inventory of our USB ports with IORegistryExplorer, we come up with a total number of USB ports under the XCH@14 branch that's larger than 15, what are our options? Just leave the port limit patch in place? Is there any sense in using a trimmed number of ports in an SSDT...
