MP 1,1-5,1 Manually Configured OpenCore on the Mac Pro

[Stez]

Does anyone know how I can clear boot caches? I think my open core install keeps getting muddled up as on boot I can see a phantom Mojave installer that isn't mounted and it boots into a loop if I select it. Can I remove it by clearing boot caches?

This is the kernel panic log that appears when I boot successfully.

EDIT: I just wiped my OpenCore install and redid it. Seems to have done the trick 👍

Hi -
Can anyone verify if the first posted instructions are still valid I download Open core 0.6.7 and the sample config file and installed it on my 2012 Mac Duel Processor 24 GB rams and it felt very sluggish. I have a high point with a single m.2 Samsung 970 Pro 512 GB on it. Big Sur 11.2.3 ran very slow.

Or point me out to a post that has the most updated instructions..
Kindly appreciated

What GPU do you use?

What GPU do you use?

I am currently using Radeon Rx 580.

​

 

[Macschrauber]

Rx580 is supported and should run good.

try a clean native installation to an empty SSD.

I've read in an opencore-on-macpro facebook group that 11.3 (latest three betas) is troublesome when installed on a 5,1 mac pro. Could this be a sign of things to come? Anyone with a similar experience?

Cheers!

If it is installed on an NVME- yes. It panics prior to initialization of the OS.

Thanks! Is there a problem with any other PCIe cards, USB3 ones for example?

I can't boot the beta OS so I don't really know what works and what not.

Another fellow cant boot 11.3 Beta when a USB3 PCI Card is in.

@Macschrauber I did do a clean install. I am currently running Mojave on a Sata SSD( this is my fall back / backup OS )

I have seen other people on the web that have custom Plist for Duel processor and another for a single processor.
Does this sample list need to be configured for such or is it already addressed ?

Not good... Hopefully there is a solution around the time 11.3 release is out

This is covered in Part 2 of the guide. See "Enabling Hardware Acceleration."

First post is up to date. Generate your EFI and config.plist based on the plistlib generator example, to be 100% sure you have a proper configuration. Manual editing is prone to errors, especially when you are inexperienced with OC.

Does this affect the Titan-Ridge Thunderbolt 3 PCI card on a Mac Pro 5,1? Do we know whether the impending OpenCore 0.6.8 solves this issue?

 

[Macschrauber]

If noone did I can test a Thunderbold Ridge end of the week with 11.3 Beta 6.

 

[eVasilis]

Just in case somebody's wondering, OC 0.6.8 is out along with updated versions of lilu and whatever green.

 

[cdf]

The guide has been updated to OpenCore version 0.6.8.

This version of OpenCore is definitely a worthwhile update. It brings many nice improvements to OpenCanopy, like shut down and restart buttons, a set-default indicator, and a much smoother input experience.

The "modern" picker theme has also been updated to match the current native theme of supported Intel machines (this is the theme portrayed in the first image of the guide).

To update, make sure to consult Part 3 of the guide.

Hi all

Just updated to 0.6.8 and the boot picker icons are huge. Am I missing something?

Thanks

 

[Dewdman42]

Just updated, thanks for all you do CDF. What is the set-default indicator? I normally am not using OpenCanopy, since I use RefindPlus as my primary boot screen... but what is that new feature in OC boot screen?

I have been looking at the Ridge stuff. But I think the speeds are not that awsome.

If you're using a non-HiDPI display, UIScale should be set to AQ==.

Awesome guide! Thank you so much!

After OpenCore configuration was able to upgrade from Mojave to Big Sur.
All hardware is working (Including the Broadcom BCM43xx 1.0 - BT and WiFi)
This is my first foray into the world of MAC and honestly it's been pretty fun getting this old girl up to date.
Going to slap some more ram in and start making music in GarageBand!

What is the set-default indicator?

If you hold Control when selecting a volume, the arrow indicator will turn into a curved arrow to indicate that the volume has been set as the default choice. The same thing happens in the native Mac boot picker.
