I hope @lihaoyun6 doesn't mind, but I went ahead and fixed VGTab so it will launch on Big Sur and Monterey.

Hi, I have added 4 new patches to UEFIPatch which add support for several C422 and C621/C622 based motherboards running a Skylake or Cascade Lake HEDT+ CPU(s). These motherboards are either Socket LGA2066 (Xeon W2xxx and Core i9 CPUs) in the case of the C422, or LGA3647 (Xeon 3xxxW/Xeon...

Catalina 10.15.3, Geekbench 5.1.0: https://browser.geekbench.com/v5/cpu/1337493 The 28-core Mac Pro wishes this workstation was its dad. The macOS kernel only supports a maximum of 64 threads (for now... ;) ) so I have to leave hyperthreading off. With it turned on in Linux...

Yes, I have seen that panic a number of times. I can tell you exactly what the cause is too, and how to fix it... or that you can't fix it, depending. If you aren't interested in the cause, just skip all this technical mumbo jumbo and go to the bottom of this post, where it says, 'OK, good...

Unfortunately, it looks like your filesystem is badly corrupted. macOS can't find certain key files it needs to boot because it can't even load them from disk. Have you had to do a hard shutdown (holding down the power switch or removing power)? That can corrupt the filesystem. If not, you...

These 10.13.6 security updates are just destroying these performance patches. Each one needs a different patch. Anyway, here is one updated for the latest security update, 17G7024. Find: C1E30848 63D389D0 48C1EA20 B9990100 000F3048 FF0559AF 6B004883 C4085B5D C3662E0F 1F840000 000000...

For Haswell, you use the same patches except for the Broadwell specific ones. There are two of those and they’re labeled as such (with “broad” in the comment section). Haswell CPUs don’t need the xcpm_cpuid_set_info patch at all, so simply omit that one. They do need a Haswell specific...

Hi, this is a combination fix & PSA for anyone using the X99/Broadwell-E Performance kernel patch. If you've installed a recent 10.13.6 security update with build 17G5019 or newer (and possibly a bit earlier, I unfortunately am not sure exactly which build the change occurred), the...

Sorry for taking so long to reply. I'm crazy busy these days. Honestly, I uh didn't even know about the HFS+ to APFS without asking policy of the 10.13 installer, and didn't even notice/realize that anything had changed for a embarrassingly long time afterwards. If I had the option, I would...

@davidahn I've lost entire weekends to dying CR2032 cells. I feel your pain. Also, do network boot roms really have a point besides providing an excellent location to install a rootkit? ;). (I'm kidding. Mostly.) Anyway, I'm running 10.13.4 like a champ! Fortunately, there aren't too many...

Electrical engineer here, I deal with these connectors all the time. And if you're having trouble figuring out the actual correct connector for mini pcie wifi cards... it's understandable. Originally, and most commonly, the connector was called a U.FL connector. Now however, the same...

Hi itsme001, this is excellent information, however I believe the coreduet problem is specifically caused by CPU thermal sensors. Why the heck handoff/coreduet is involved with thermal sensor telemetry, I have no idea, but that's the specific task that was causing it to stall out. Only apple...

It doesn't matter which specific combination of GPUs are in a machine (including mixing AMD and Nvidia cards, despite what unsubstantiated superstition in some threads would have you believe). The driver supports both the maxwell-based titans as well as the Titan Xp, so that's all you need to...

I am not sure how many people this effects, but I imagine a number of users with a relatively recent NVIDIA or AMD GPU have been experiencing persistent graphics issues in Chrome since at least 10.11. These issues include: Garbled browser page content, often appearing as blocks of the page...

Crap, I am so sorry guys. So, I, uh, completely forgot that I had patched the BIOS image from Supermicro for my motherboard and flashed my own modified BIOS to my X10DAi mobo. It was largely cosmetic (replaced the Supermicro logo with the Apple boot image, restored some stuff that had been...

Er, no. This is not 'pre-clover'. The only thing preclover is the BIOS which loads a UEFI bootloader (Clover in this case). And no, the problem is with neither of those things. The row of pluses '++++++++++++++' is just a very basic progress bar shown by Clover (since, as I said, this is not...

I don't know how many people this effects, probably not that many (I haven't really investigated further, but it might even be specific to certain SMBIOSes, it is certainly an issue when using the MacPro6,1 SMBIOS at any rate). I was plagued by very vague 'working-but-not-really' problems with...

One of the issues that causes a lot of confusion (at least, in my opinion anyway) is that there is a tremendous amount of just really terrible ASL (DSDT/SSDT) code that is floating around in the hackintosh-o-sphere, and it keeps getting used by people who don't really understand what any of the...

Seriously. What are they looking at? They're all looking UP at something. But what? Maybe this is not the right forum section, but this has been bugging me for literally years, and I finally just had to ask. I mean, they're awesome little avatars, I love 'em, but particularly that...
