As an alternative to Command-R, you can try entering the following command in Terminal when booted in Mojave: sudo nvram "recovery-boot-mode=unused" && sudo reboot recovery

If Recovery still doesn't start, then your current installation of Mojave may be borked, in which case, a clean install would be a good idea.

Hey - thank you for the quick reply! I tried your approach in terminal and failed to boot to recovery (instead it booted into my typical Mojave). I did a NVRAM reset and tried again and it still failed to boot to recovery. Alas.

So, just confirming then - it looks like the best approach at this point is to do a fresh install of Mojave to get recovery back and and then go down the open core path?

I do have the original 5770 graphics card that came with this computer - I don't know if that enables any additional options if I were to pull out the RX580 and replace it? Honestly a clean install is probably overdue anyway, so I'm not super worried about it either way.

I'm trying to remember if I've ever done this since losing my boot screen. Is the approach to:
1) create the bootable usb mojave installer via createinstallmedia (I've already done this)
2) pull out the current boot drive and all other drives
3) put in new formatted target installation drive into SATA and the USB bootable installer in USB
4) reboot and wait for it to find the USB installer drive?

Many thanks!

A good installation of Mojave should be considered a prerequisite for setting up OpenCore. If you've exhausted other standard options (full 3X NVRAM reset), then a clean install of Mojave is the best approach.

My favorite approach is to start the installer from an existing installation of macOS and to select a freshly formatted drive as the destination.
 
SuperDuper does not clone the Recovery partition. Use CarbonCopyCloner instead (30-day trial version fully working)
Thank you - that definitely identifies the mistake! Oh well. I'm sure I've lost the original at this point and will do a fresh re-installation. Good to know for future reference - I actually own Carbon Copy Cloner, I just hadn't considered it for this job.

Thank you for your help so far. I'm guessing this is a bone-headed question, but I'll ask anyway since I see reference to 3x NVRAM reset as part of the open core process once I'm back on track: what exactly does a 3x NVRAM reset entail? Is it holding down command-option-p-r for a very very long time until you hear the chime 3 additional times (beyond the first one?)? Or is it just doing an NVRAM reset letting it boot, and then repeating that process two more times?

Thanks - I tried searching first but didn't come up with anything.
cheers!
 
Hey guys,

Is there anyway to make 6900XT Ref Card working? the CMP 5,1 sees the the card, but it doesn't recognize card as 6900XT.

No one ever got a NAVI 2x GPU working with a Xeon processor earlier than IvyBridge generation.

Navi 2x eGPUs work with MP6,1 and MP7,1, but not with MP5,1.

Hi, anybody running 0.7.5 with BigSur and has running internal Bluetooth ? I have the upgrade Wifi/BT osxdaily Board. Wifi Running well but Bluetooth not available.

any suggestions or update highly appreciated.
 
Note that there is an issue with Lilu 1.5.7. It will be fixed in the next version:

I have the 0.7.5 package running 11.6.1 with an AMD Radeon HD 7950

I am getting the random GPU Resets and Kernel Panics (userspace watchdog timeout) and reports show:
2021-12-02 08:48:39 Kernel Panic (5 times)
3rd party kernel extensions:
as.vit9696.Lilu
as.vit9696.WhateverGreen

The odd thing is that I can do video-intensive things all day with zero issues but the problem comes up when running Carbon Copy Cloner or closing the Music app and may hang when scrolling in the finder a couple of times. I did turn off hardware acceleration in Chrome and that helped with Chrome freezing.

I had 10.14.6 that was rock-solid prior.

h9826790 - I have a mystery for you. I'm running OC config 0.7.5 in a multi-boot environment, with OC residing on an EFI partition other than macOS. After installing OC, I changed the name of the ssd containing Mojave. But the bootpicker is stuck showing the old name. Where exactly does this name entry reside, and why does it not update when OC scans the drives?!

Old matter. Don´t worry. Eventually it will revert to right name.
 
OMG, I just figured out the problem. I switched D+, D- while soldering. Now it works

On my 5.1 MP 12-core and 6 core (mid 2010) with 0.7.4 and updated to 11.6.1 this works (-ac and Bt4.0): BCM94360

Bought through Ebay as "Apple Mac Pro 2009- 2012 WLAN Wifi AC & Bluetooth 4.0 kit - Plug 'n Play" without any soldering (for the sake!) – but to plug the 4 antennas in a row was quite a tricky finger work deep downwards in the case ?
 
Hi, I have very strange behavior on my Ryzentosh (Ryzen 3900x, Radeon RX 5700 XT 8GB, 64GB RAM, 2TB SSD, BigSur 11.6, OpenCore 2.0.4) in Final Cut Pro X with Sony A7s III footage. The footage (4k, 10bit, 4:2:2) plays smoothly in Davinci Resolve, but in FCPX the playback starts to shutter after 3 seconds. Clearly this is not a HW problem, the Ryzentosh is perfectly capable to play this footage smoothly. But somehow in FCPX the performance is much worse. I know about QuickSync missing in Ryzen CPU, but I'm not sure it is used during footage playback or only in export. Thank you for any suggestions :)

Btw. in VideoProc I have both h264 and h265 aceelerations enabled.

Hi, I did the easy to install package on p53 (is this still the latest way to go?)
and it just worked half way. Videoproc says HWACC works but via apples website for older OS it doesn't allow me to download Big Sur or Catalina. Only Mojave or Monterey.

also it doesn't go for boot screen or picker but that's not the most important.
what is wrong?

Its a Mac Pro 2012
6 core with RX 570 4GB

The screenshots are in German but it just says that Catalina installation is not possible and that the download is not available.

Thank you a lot

Apple still have the Big Sur installers available, but it's not easy to get, the page below have all the links, current release is 11.6.1, next week will be the release of 11.6.2:

 
Hi,

I have a:
Mac Pro 3,1 2008
AMD RX570
OSX 10.15.7 Catalina installed with dosdude1.

Coming from a fresh install, VideoProc says that HEVC is activated but not H264.

I have followed post #594 as well as #1314, but both instructions gives me a black screen without being able to boot back. 3xNVRM will not help, the only way back is fresh install.

What am I doing wrong? Please kindly help me
 
****Fixed it. When all else fails, 3x PRAM reset always there to save the day. Bluetooth "on" icon likes to come up right away too in the clock bar instead of being delayed 5-10 minutes. I should have known better but was lazy due to just updating OC and Big Sur to the latest and Monterey****

----

TOPIC - 5.1 mac pro not seeing external hard drives or internal hard drives (minus the system/boot drive) after update from big sur to monterey (OC using martins 7.5 package was used). Aside from this, Monterey and system boot and load/work fine, just can't see any external or internal drives in finder or disk utility or in terminal -> diskutil, but they show in system info.

----

I already was on Big sur for 6-7 months working great, with martins 6.3 oc release on my 5.1 Mac Pro. Decided to upgrade oc to 7.5 and upgrade to Monterey 12.0.1 per instructions from max sound solutions video from November 7th on YouTube. The Monterey upgrade went smooth and all works correctly except for one weird thing (yet important).

Only odd thing is external hard drives or internal Sata drives (including the optical drive), aside from the system drive, don’t show in the Mac OS finder or disk utility. They will show on the boot selector or open core and show in system report but not in finder or disk utility. Another odd thing is one of those drives is encrypted and asks for the password to mount. I have tried canceling that prompt, typing in the password and clicking ok. And also clicking “save to keychain”. But still no luck with any other drives showing in finder or disk utility
?


The oddest thing that is driving me crazy. Any help would be appreciated
?


If i'm missing something and this is an easy fix, i've noticed that my keyboard and mouse (both BT) work just fine from a total shut down and fresh boot or even a restart. But the bluetooth icon up top by the clock has a cross through it and bluetooth appears "off". The keyboard and mouse all still work fine but scrolling on the mouse (magic mouse 2), doesn't work. It takes about 10 minutes or so and both keyboard and mouse disconnect and reconnect automatically and bluetooth shows "on" in the clock bar and scrolling works fine. This happens each time i do a fresh boot or reboot. I know there are issues with the legacy BT and Wifi card, but seeing this with the upgraded one. Wifi works fine. I know there will be quirks and such but figured i would mention this too
?

Hyped with the whole OC Project and everyone's time. Thanks again crew!
