Both disk must be SSD 2.5?
Could Disk A be HDD 3.5 or USB ... ?
the EFI disk must be internal?
all the time for ever and ever will connected to mac pro 5.1?
Like @cdf mentioned, as long your disk is bootable, you are fine. However, my preference is to have Mojave installed on an internal SSD installed into SATA Slot 1. That is a key location, vital for having a rescue disk in place to refresh your BootROM (most important) or to boot from an unmodified OS.

Also, I run Big Sur and Windows on NVMe blades, to get read and writes of 2500-3000MB/sec.
 
Hey Guys, Download OCLP 0.17 today to update OC on my late 2012 MBP but after it installed in my EFI i could not boot my mac again, lucky i had an old efi i created with OCLP 0.12 which i put back into the efi folder after booting with it and it works again. Anyone else having issues with this newest update. also noticed the new OCLP installs Open Core 0.6.8
 
You can always boot BS directly with -no_compat_check set and compare the results. But I think it is your titan-ridge which is breaking sleep especially if you have USB device connected to it.
Hmmm. You might be onto something, although I remember I used to have two sliders for Energy Saver in Catalina (with OpenCore, of course); I already had Thunderbolt back then. Only yesterday did I notice the "main" slider was gone. I'll look into it and see what happens if I boot Catalina now using the latest OpenCore.

There is only one power slider now in BS.
 
Here's a fun one. Running the Martin Lo 0.6.7 package, I loaded BS11.2.3 successfully this morning. I run Parallels 16 to get my Win10 running, and on Mojave there's no issue. On BS, the Windows version of Calibre ebook management now shows book viewers as completely black panels, no controls or views whatever. The Calibre maintainer noted: 'This will be an incompatibility between your GPU drivers and QtWebEngine the library the viewer uses for rendering.' along with a suggestion to update the drivers or disable video acceleration in Calibre/QtWebEngine.
So, where's the GPU fiddling that must be undone? In Martin Lo's package, in BS, or where? It's not the basic Mac side, as I can run the macOS version of Calibre just fine, so the basic drivers are good.

Anyone got any advice regarding my issues above please.

Open an issue on the developers GitHub page if you believe to have found an issue. Since the most recent version is 0.0.18 you may first try this latest and greatest version.

Honestly this cannot become the "fix my EFI" page for all available sources of OpenCore configurations.

On the dev GitHub page I tried but cannot comment on the build or ask anything there, the latest version there is 0.0.17, does not show 0.0.18.
Honestly this cannot become the "fix my EFI" page for all available sources of OpenCore configurations. - This comment is a bit harsh given that many are asking questions on here about OC builds and getting help and is this not what the thread is for - OpenCore for Macs!!!! I am not asking to fix my EFI, I am asking if anyone else has tried this and had any similar issues

You wanted ans answer so badly (anyone..), now you have it and your are still not satisfied.

Again:

This is a thread focussing on a certain kind of OpenCore config described in detail on the first post. Most likely for that reason you got no answer on your request.

There is no forum for OCLP here currently set up, the closest might be the Big Sur thread. The developers of OCLP are active on Discord, not here, not on the other thread.

You might try to search the forum list for a better place to post, yourself. Was this too harsh, again?

If you do not get an answer on your first question, do you really believe this "anyone..." posts are helping?

The 0.0.17 has been updated 3 hours ago, it is a moving target.

Well I must say Thank you for the advice about the discord, I have now signed up and posted there for advice and next time don't be a meanie

According to https://www.tonymacx86.com/threads/computer-sleep-slider-bar-missing.222369/, this single slider issue predates Big Sur, and seems to have been coded into macOS (Catalina?) as a simplification of energy saving options on certain particular Macs, and the choice of whether one or two sliders were shown depended on the particular Mac model as indicated in the relevant /S/L/E/IOPlatformPluginFamily.kext/Contents/Plugins/X86PlatformPlugin.kext/Contents/Resources/MAC_MOTHERBOARD_IDENTIFIER.plist. What I'm wondering now is whether an Mac Pro 5,1 masquerading as an iMac Pro 1,1 should have such options decided by the existing Mac-7BA5B2D9E42DDD94.plist or the non-existent Mac-F221BEC8.plist. If the latter, whatever improvement (if any were feasible) would require the inclusion of such a file. If the former, editing Mac-7BA5B2D9E42DDD94.plist might be needed for said improvement (if feasible at all). I've noticed two keys that might be relevant:
  • DeepSleepCap[ability] is set to false (!)
  • UnifiedSleepSliderPref is set to true (!)
If this is what dictates the way energy saving works on a Mac Pro 5,1 masquerading as an iMac Pro 1,1, I wonder what the effect would be if we were to reverse DeepSleepCap to true and/or UnifiedSleepSliderPref to false. Any comments?

I understand that you are frustrated, but you are forgetting that this is a Mac Pro thread, see the title of the thread and the sub forum you are, while someone here could have tried OC with the same Mac you have, it's not the focus of the thread and you probably could get better help on the MacBook Pro sub forum.
 
Hello. Big Sur 11.1 is not installed on my Mac Pro 4.1> 5.1. When you select a drive for installation, the message "This update cannot be installed on this computer." The installation is clean and I use Open Core 0.6.7. Catalina installs and works well. Please help solve this problem.

P.S. Catalina has been successfully updated to big sur 11.3 beta

It would really help if everyone would apply a signature to your account as to what exact equipment you have. It helps the help. Also, as stated by @tsialex, this is a Mac Pro thread. Hence the title has not changed and I'm sure the focus won't either. Just saying. Enjoy your day and turn those clocks up an hour.

No issues mate. It is all sorted. The dev helped me fix it and now it works like a dream
 
APPENDIX
Installing Windows and Linux
Installing Windows 10

In the Windows installation part of this guide, there a section called "Proceed with the installation" where I'm getting an error!

I didn't even try to proceed beause I'm not what would happen.
Any ideas why this might be?
 
I'm going to be crazy...

I have 2 Mac Pro 5.1 (mine is mid 2010 dual Xeon, and my wife's one, a late 2012, mono Xeon). Both with Big Sur and OC 0.6.7.

My Mac Pro goes perfect, without isues... but the other... the other will meke me crazy!! Some times, in a cold boot don't recognize the mouse or bluetooth... other times, when power up after hibernate, don't recognize the mouse or bluetooth... and other times, random, without hibernate, writing an email for example, the same trouble...

The bluetooth it's a USB dongle attached to the Apple's keyboard (the usb dongle it's ok, it's the third with the same issue). I was try to attach this dongle to the front and rear USBs directly... and the same issue...

It's like if all USB turn off, becouse the keyboard (I test with 2 keyboards) don't work too when the issue (for example, I press Caps Lock and don't brigth the led).

If I disconnect and connect again the keyboard, all will work again in 5-10 seconds...

Do you know what can be???
