Thanks a lot. I' ll try this and report. Disabling OC, setting the Bootvolume in native-Mojave and re-enabling should do job?

The guide describes what you need to do step by step, but in case you're curious, here's a supplementary explanation:

The key is RequestBootVarRouting or "boot selection routing": boot through OpenCore as usual, turn off boot selection routing, reboot (your Mac will still boot through OC, but boot selection routing will be off), select Mojave in Startup Disk (because you turned off boot selection routing, the selection will be used by your Mac's firmware not OC), finally reboot again. Your Mac will then boot Mojave natively.

Hopefully a quick question getting thrown into this thread. Upon boot, the loading bar (which sometimes doesn't move) and Apple logo disappear, and I get hit with a intense full-screen white flash, then black, then the loading bar & Apple logo reappear before the login prompt. Is that normal?

Video of the issue, here, for anyone curious (happens at 20sec, audio for emphasis):



If this is normal, and there's no way around this, then I'll just make sure to never turn on my system in a dark room. Since, after a few boots last night, my eyes still hurt. If this isn't normal. I hope its not my GPU, it's already given me enough gruff. Maybe there's a possible fix in OpenCore?

2010 MP 5,1; 2x X5690; 10.13.6; 2x 860 EVO SSDs (1 boot, 1 w/ OC EFI); stock MSI "RX 580 8G" Reference; 2x Sonnet 4port USB3.0; 1x ATTO FastFrame NS11; Intake/Exhaust Noctua NF-A12; Followed cdf's tutorial Parts 1-3 (all except Night Shift), OpenCore 0.6.7

Updated to 11.2.3 with OC 0.6.7: no issue on my cMP 5,1
Click to expand...
Same here using v0.6.7. Couple of butt-clenching moments though where I thought the system froze or crashed.

In a nutshell:
  1. VMM off (virtualization instead)
  2. Updated via OTA
  3. First reboot, OC boot picker showed "Macintosh HD" rather than "MacOS Installer"
  4. Fairly long 1st stage boot screen load times (progress bar froze for what seemed several minutes then rapidly moved up to about 80%)
  5. Reboot. This time boot picker showed my Big Sur SSD hard drive (and Recovery volume version changed to 11.2.3)
  6. 1st stage boot screen immediately at 80% (it appeared to freeze again here, then reboot. Thought it KP'd at this point)
  7. After seleting Big Sur SSD volume again, 1st stage boot screen appeared for another couple of minutes before finally going to login prompt.

Same experience here!
 
@amstel78, While it's nothing to worry about, OpenCore is setting your processor speed in the SMBIOS as 3.45 GHz instead of 3.46 GHz. Please check if a reboot or two fixes this. If not, a DEBUG log would be useful to help improve the rounding algorithm.

Sure, will keep an eye on it. Thanks!
 
Not seeing 11.2.3 on my MacPro5,1. Using OC 0.6.7 and config.plist from first post - only mod is Board ID spoofing and VMM OFF. Confirmed 0.6.7 is installed in terminal. No hardware acceleration - I have a GTX 680.

Thoughts or things I can check?

updating to 0.6.7 changed my clock speed to 3.45ghz also and I was wondering why or if that is a problem?

Version 0.6.7 brought support for processor speeds with two decimal points. However, because some 3.46 GHz processors are showing up as 3.45 GHz, it seems that the rounding algorithm needs some refining. A DEBUG log would help for this.

I don't think you can get much from the debug log as it always showed the correct value. But I see here:
FSB: 132999999Hz, 132MHz Which is a weird rounding. But actually if it was 26x133 it would be 3458 and now is 26x132=3432

The rounding is based on the CPU frequency that appears there. For the X5690, the rounding was based on a value of 3457999888 Hz, so in your case the speed should appear as 3.46 GHz in About This Mac (with hybridization, of course). Is that what you're seeing?

No, it is 3.45. But as I said even before the recent frequency code change Intel TSC: 3457999990Hz in the debug log was always the same. What I am trying to say is that OC was not using directly that value.

The fact that it's 3.45 should be reported. The rounding algorithm indeed uses the CPUFrequency value. Here's the code:

well this is clearly wrong:
Code: 
if (MhzRemainder >= 50 && MhzRemainder < 90) {
    MhzSpeed = (MhzSpeed) / 10 * 10;
  } else if (MhzRemainder >= 12 && MhzRemainder < 90) {
    MhzSpeed = (MhzSpeed + 5) / 10 * 10;
  } else {
    MhzSpeed = (MhzSpeed + 50) / 100 * 100;
  }
Click to expand...
Where is the case where the remainder is >90? Is it MhzSpeed = (MhzSpeed + 50) / 100 * 100? That would be 3500(3.5). This is what we had before. How is it calculating 3.45 then?
Edit:
it looks like it is using case 1 MhzSpeed = (MhzSpeed) / 10 * 10; 3458/10*10=3450=3.45

For the X5690, the remainder is 58, so the calculation is actually doing MhzSpeed = (MhzSpeed) / 10 * 10. This gives 3.45. It should actually do MhzSpeed = (MhzSpeed + 5) / 10 * 10. I think the issue is due to accommodating the weird rounding down for 2.66 GHz processors...

So the first case should be removed altogether and it should be:
Code: 
if (MhzRemainder >= 12 && MhzRemainder < 90) {
    MhzSpeed = (MhzSpeed+5) / 10 * 10;
    } else {
    MhzSpeed = (MhzSpeed + 50) / 100 * 100;
  }

using appleALC alcid=13 as per PR #75, no audio devices, no nvidia HDMI audio, firewire works.

Im clearly an idiot and don't understand something Im not doing before I go to do everything I have this window and I assume its stopping everything from working correctly

Does someone have X5675? Can you please enable logging and see the frequency and compare it to the one in About this Mac:

I know @startergo already filed a bug report, but just to answer your question: no, a reboot (or multiple) has no bearing on algorithm output.
