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

[cdf]

I have looked through this thread and searched globally to determine if Filevault 2 can be enabled under OC. I am afraid I am a little confused as some say Yes and some say No. I have a Radeon RX 580 8GB, running Catalina on a NVMe SSD, I have the gui bootpicker enabled. In settings, the "Turn On Filevault" appears to be active. I had turned off filevault before setting up OC but would like to have it on if possible.

Is it safe to enable it?

Thanks

I use it myself. It works great.

How do you decode the ROM output --> 70cd609d9be6 to which rom the system really reads?

There is no need to change the ROM on the cMP. The ROM in combination with the MLB and other parameters are used for the imessage keys creation. We have already confirmed that changing only the MLB, spoofing iMacPro in the SMBIOS section only does not affect the imessage keys compared to the original cMP registry, but changing those values in the NVRAM may affect the imessage keys. If you open hackintool at the bottom of the first page you will see the imessage keys.

His question is that he ask for help, where some on this forum should understand that not all information is just that easy for others to digest.

Have you check this encyclopedia on this topic and think that every cMP owner would easily understand?

I gave the best advice possible: go over the guide and create your own working config. It's really not that hard. The wiki is up to date and tells you what to do step by step. After, if there is still an issue, I will gladly offer more help, just as I have since the beginning of this thread.

The answer to your question is "yes" and "I hope so." In fact, I have spent many hours studying this topic even before it was a topic here, and I have spent many hours writing a comprehensive guide to make this topic as accessible as possible. I like to think that it was worth it.

Did the same thing and still learning. It is a fantastic weapon if you know how to use it . Still learning myself all good man. No worries...

Thank you I appreciate the explanation, but I'd like to see what translate that rom 70cd609d9be6 and with numbers it will return..

Thanks @cdf and others for creating the fantastic guide to OpenCore. I took the plunge yesterday and have everything set up with Catalina and Win 10 on separate drives. I'm now trying to set up Parallels to use the Win 10 (EFI) disk, but it gets stuck at the configuring stage, with a black screen and a white box, with some options that don't respond. Is this because the install isn't strictly speaking Boot Camp? Anyone know a workaround?

I am not sure about parallels, but in Virtualbox you can change the bios to/from EFI, which is what affects Windows Bootcamp/UEFI mode.

Got a question... I'm using OpenCore on a Mac Pro 5,1 with an XFX RX580 4GB and my boot screen is a greenish color until it reaches the OS. Is there a way to fix this?

 

[jackfennimore]

What I mean to, say sorry there was a type due autocorrection on these F machines. What I meant to say is that you always want to keep a partition ( the B ) just in case something goes wrong with Catalina, so that you can always fall back on your feet and restart all over from the B if Catalina is screwed... Got that? Keep that B drive with whatever is on.

Drive B is just a fresh Mojave boot drive. its not a backup of anything. i don't see the value on keeping it around. correct me of i'm wrong

it’s only needed for the set up of Catalina, so any old SATA drive will do.You can take the drive out afterwards and stick it in a drawer in case it’s needed In future.

I am not sure about parallels, but in Virtualbox you can change the bios to/from EFI, which is what affects Windows Bootcamp/UEFI mode.

I wouldn’t want to change the mode of the Windows install - it should stay as EFI. I just want Parallels to be able to use the disc. It may not be an issue with EFI, unless Parallel’s expecting a Mac Pro to be using a Legacy install for Bootcamp.

I wouldn’t want to change the mode of the Windows install

That is not what I meant:

KB Parallels: Unable to start Virtual Machine - EFI Boot

The virtual machine loads with some EFI Shell commands:

kb.parallels.com

you need vm.bios.efi=1 for UEFI boot.

Try setting the switch on the RX580 to the non-gaming mode. It is on the top side of the card. Really tiny. Slide it away from connector end.

Power down first of course.

Wow this is a really complicated thread. I think this is what I get from studying this thread. Patcher like dosdude patches the MacOS installer to work on 5 1. Opencore fools the MacOS installer into thinking it's a compatible mac. This is better because it will allow updates to work seamlessly? Am I correct in my understanding? I would like to keep using my mac pro longer and it seems like opencore is a good option.

I haven't used the dosdude patches but can say that OC does indeed give a boot screen where none existed and does allow native upgrades. I followed the process in the very first post and it works fine. The first post is updated to reflect the best path for doing this.

Good luck

Something to consider if you installed Windows using the guide: The EFI partition does not contain the Windows bootx64.efi (to help prevent Windows from starting outside of OpenCore). I wonder if the virtual machine needs this file...

It's already like that. But just for fun I switched it towards the power connector and it had no effect. Any other clues?

i did miss it, thanks for mentioning again. if i ever run into trouble with opencore, couldn't i boot into recovery and start over? i don't see why i need the whole unused Mojave OS taking up a disk.

what's an example of my needing it in the future?

 

[tsialex]

A software update that mess with pre-boot files or an unsuccessful OpenCore upgrade. Things happen, be prepared.

I managed to mess up my Catalina disk and booted to the original Mojave disk to redo the OC install (didn't reinstall Catalina it was fine just wouldn't boot to it). I was glad to have the Mojave fallback. I suppose you could go to the recovery partition but then you would have to do all the OC set up in terminal (and I couldn't boot to the Catalina recovery partition). I use command line all the time for my work but don't think I would want to install OC with it. I have 4 2TB SATA drives so having one as a Mojave backup is no big deal to me. I have Catalina on an NMVe SSD. 1 SATA has a Windows install. So, I have 2x2TB SATA available.

You may need the disk space so perhaps you see it differently. Disks are pretty cheap though so you could pull the Mojave and replace with a blank disk. If that's not an option and you really need the disk space that Mojave is taking up then your decision is made for you.

Setting the switch cleared it up for me. What kind of monitor do you have and how are you connecting the RX580?

Well you should then put a back up system on it... If you do not have already a Mojave partition I aid just in case something goes wrong with your Catalina installation.

I keep a small Mojave drive with a few basic utilities and ALWAYS a copy of the last 2 working OC Catalina's EFI partition's contents in folders on the Mojave desk top. If something goes wrong I can swiftly use the latest to replace any messed up configuration.

It has been well worth the small effort required on several occasions.

If you don't, please don't come asking for someone on this forum to provide a rescue.

The only information anyone needs to digest to set things up is in Post 1. Everything else is discussion around this as things have evolved and key items from this discussion goes back into Post 1.

Post 1 cannot contain every single useful item discussed but is enough to get up and running.

Does anyone noticed that booting from OpenCore menu from any macOS Recovery when using csrutil disable the system says that "csrutil: failed to modify system integrity configuration. This tool needs to be executed from the Recovery OS" ?

And also, is there a working method from OpenCore 0.6.0 to set csr-active-config to w%08%00%00 ?

Do you have csr-active-config in your config.plist?

 

[jackluke]

Yes, I should remove ?

Why macOS Recovery (and also macOS Installer) isn't detected as a Recovery when booting from OpenCore menu ?
