Ultimate Mac Pro 5,1 One More Thing... EnableGOP

This video shows you how to flash EnableGop into your Mac Pro 5,1 Boot ROM enabling the native Mac OS boot picker with almost any graphics card. If your GPU works in OpenCore it will work with EnableGOP and this really gives you the Ultimate Mac Pro 5,1! #macpro #enablegop #opencore
Remember to disable SIP if it is not already disabled which you need to do when installing opencore or flashing firmware with El Cap or later.
How to Disable SIP ( I forgot to note this in the video)
Boot into recovery mode
Open the Terminal app
Type “csrutil disable” without the quotes
Hit the Enter key
A message will confirm System Integrity Protection is now disabled
Restart your Mac

[@MacSoundSolutions]

Important Note!!!!!!!!! If your Mac Pro is still a 2009 4,1 you need to do the 5,1 firmware update first before doing EnableGOP process. Also If you are using a Sonnet McFiver or other Sonnet cards you may run into an issue. The McFiver stops EnableGOP from working when holding down the option / alt key after installing EnableGOP. I had to remove my Opencore and Windows drive to be safe, install my Mojave drive and then I could boot into Mojave with my RX6800XT and get the Apple Bootscreen. It's a strange bug with the McFiver and possibly other Sonnet cards when holding down option at boot which is what you have to do to get EnableGOP to load before the Opencore boot picker if your using Opencore.

[@techpchouse]

but we can use them after flashing with GOP or?

[@MacSoundSolutions]

@@techpchouse yes, and you don't need to remove them to do the flashing, just when you want to use EnableGOP if your using Opencore you have to either pull the McFiver or easier pull opencore and windows if you have it installed and boot into a Mojave drive which will then give you the boot screen no need to hold down option. I have to try this again as it's been a while. might have to make a follow up video....

[@toncarioca75]

I did the process and disabled system protection, but even so, when installing firmware 5.1, the following error appears on the screen: The program has enconuntered an error: 5570

Log another success story! 2010 5.1, 10.14.6, Sapphire Pulse Radeon RX580. Macschrauber was a pleasure to deal with in getting the boot ROM rebuilt and he even provides an extra rebuilt .bin file with Enable GOP 1.4 already injected

[@MacSoundSolutions]

Yes he did the same for me and he went the extra mile because I was having issues.

[@TheAppleLab]

thanks for the mention lance...

[@MacSoundSolutions]

your video helped me figure it out although when I saw errors after analyzing my rom.bin with the dump tool I sent it over to Macschrauber for a rebuild. Better safe than sorry. I had a major problem though and need to mention it, my Sonnet McFiver was blocking EnableGop from being able to load if I held down the option key and it was driving my crazy I would get the grey screen but no Apple boot screen. Martin Lo mentioned that it might be the issue and sure enough it was. Pulled out my Opencore drive and booted into Mojave without holding option and there was my Apple bootloader even with the rx6800xt and no driver for it in Mojave.

[@TheAppleLab]

that was a great benefit since the very first version of enableGOP. booting every version of macOS with a modern gpu. 😌

[@neytirisbest]

Hey Lance, can you read thoughts? Mine? This was exactly what I was thinking about today! I got my MP 5,1 now pretty good, 12 cores Westmere, 64 Gigs of RAM, Monterey coming from NVMe, added a (PC-) RX580, everything´s great BUT: no bootscreen... (though they sold me the GPU with a patch, but that was obiously overwritten by OCLP....) Now, I have to sleep a night over it, but I think I will risk it so far no error messages occur beforehand. That would be fantastic cause I could possibly use (fuc..) Windows for games from a seperate HDD without a VM. I really appreciate your work, thank you so much! Dear greetings from Germany (and please keep your fingers crossed for me and the 5,1). Frithjof

[@MacSoundSolutions]

If you hold down the option key when booting you should get the Apple boot picker from your video card if it is actually patched, Opencore does not over right the efi on the video card. Just gives you the bootloader when there isn’t one. Or if you pull out the Opencore drive you should get the bootscreen with a Mojave drive installed no need to hold down option.

[@neytirisbest]

@@MacSoundSolutions Hi lance, thanks for the hint, I ´ll try again. But so far that didn’t work. The problem is that the card was only „patched“ in the Mac-EFI but not in the GPU hardware itself. I ´ll give you response if it works. Greets.

[@LeonPhythian69]

[@ladeluff_]

holhoy mama Lance. GREAT feat

[@douglas_edward]

Thanks for the time and effort you put into this. I'm glad it isn't a minute shorter. There is nothing in here that can be cut out. I've been following ebableGOP since it launched but haven't decided to do it yet. Seems to me it does introduce a risk that you wouldn't have without it. If one boots with option held down, then uses the Apple boot picker to select a Windows drive (EFI installation), then it would launch Windows without OpenCore protection and lead to certificates being written to the boot ROM and ultimate corruption of the Boot ROM. Am I right?

[@MacSoundSolutions]

Good point, but seeing Windows 11 is a UEFI install I don’t think it will show up as a boot choice with native Mac boot loader, if it’s windows 10 legacy install then maybe that could then happen but you would have to select the windows drive. Good point though and I will look into it.

[@douglas_edward]

@@MacSoundSolutions yes I think you’re right. I may do the enableGOP on a free weekend this winter. Thanks again for the excellent video. And, using the one more thing…. line was sharp.

[@_emjaywlz_]

Another great video, Lance! Thank you for posting this very thorough video! They're the best! Since I'm an OCLP user, any thoughts on this working for us, or is this strictly a MLOC thing? Much thanks! All the best! ~ MJ

[@MacSoundSolutions]

Yes it will work, it loads before Opencore doesn't matter the version of opencore, if you hold down alt key after boot chime, it will give you the stock Apple bootloader. Again this is for GPUs to show the bootscreen that normally don't, if you use Opencore yoou don't need it unless something goes wrong with OCLP or ML then you can boot with a non apple gpu and still get the apple bootscreen so you can select a mojave drive to boot from etc, its a great fall back.

[@_emjaywlz_]

This is of particular interest to me, since having a 6900XT using Syncretic's patcher, I don't get the option for macOS bootloader anymore, and my startup screen goes directly to the OCLP boot loader. Which, thought not the end of the world, does not allow me to choose any other macOS or Win Installs. Thanks Lance@@MacSoundSolutions ! Much appreciated! ~ MJ

[@MacSoundSolutions]

@@_emjaywlz_ Windows should show up in the Open core boot loader but you probably have to reinstall windows first at least when I installed windows on my 6,1 Mac Pro I installed OCLP first then I installed windows 11 in UEFI mode using Rufus. If your windows install is an old boot camp install then most likely “legacy patcher won’t see it but I’m not sure about that and the other thing is when you install “legacy patcher it could’ve erased your Microsoft folder which tells “legacy patcher that you have windows installed. But I’m somewhat new to “legacy patcher and I’m still messing around with windows because I couldn’t get sound out of my 6,1 Mac Pro and I installed the boot camp drivers and that messed up my graphics driver so I have to try it again from scratch but Sonoma is working well with OCLP and the 6,1

Hi, Thanks for the video - not a second too long. Is it it really necessary to have 2TB SSD - just for Open Core(or do you keep anything else on your Bay1)?

[@MacSoundSolutions]

The drive can be any size, I just use it as my main audio project drive. Opencore is stored on the efi which is a very small partition.

Man great video! This is definitely next on my to do list. I wish they had someone to try the 6600xt. I’d love to replace my rx570 with one- though I guess with the pixlas mod I could go with a 5700xt for a good boost as well.

[@MacSoundSolutions]

6600xt is one of the supported GPUs no pixlas needed just flash with Syncretic’s patcher. Check out my other video on it I show you how to patch the RX 6600 XT.

I am in the same boat: still using a 2010 Mac Pro, tuned as far as it will go, because it still does the job well enough; holding off until an M3 Mac Studio becomes available. I wonder how many of these wonderful old tanks are still in front-line use?

[@skip741x3]

Seriously cool that this can be done! Im probably gonna pass on doing it for 2 reasons... I use an rx570 and the boot screens are there already ..Im not worried about having to throw the gt120 into it for an emergency.. ..I had a hell of a time with a windows pc that I added nvme boot capabilities to its rom..similiar process of injecting a driver into the original rom and reflashing... it Did work but unfortunately, I had to try the process a 2nd time and the flash was Within the windows enviroment... The flash process that worked fine b4 decided to halt at 3/4 of the way through and froze my pc.. only thing I could do was a hard shutdown and you guessed it, my bios was bricked ..I just ended up swapping in a used motherboard, as the bios is soldered in.. cost 10 bucks and alot of grief... Ironically, I Had nvme boot capabilities with the opencore that I used on that dual boot pc/hacintosh machine... I never bothered to do the bios flash mod on it after that.. there was no need and I didnt want to take the risk again...The novelty of adding nvme boot capalities or the ability to have a native bootscreen with any card, it IS wicked cool though!

[@MacSoundSolutions]

Yes not really needed if you use opencore, but I like to tinker I can’t help myself and it is very cool that it can be done😎

[@filmxenrique]

Thank you for sharing!! I just came across a 5,1 yesterday and I’m wondering if I can upgrade it to edit 4K videos in Final Cut Pro and if it could game on 144 fps - from your videos it seems doable, I was wondering if you could help me formulate my options for upgrading

[@MacSoundSolutions]

My main monitor runs at 120hz but most games don’t go over 100fps at 4K with my rx6800xt if at high or ultra settings when running Windows. So while you may get 144hz out of your monitor you most likely will not get 144fps at 4K with most games.

[@fleonard4]

One down, two to go! Thanks! I did just have very strange keyboard behavior, and had to unplug, and plug back in my keyboard. Other than that, it went ok, and I wanted to note something for others. I was wondering if it even worked, because no white mac boot picker. But, I figured it out. I have 128GB RAM, and my display goes to sleep during the cold boot. By the time it wakes back up, it's to the OC boot picker already. My NVME boot is very fast, so the only way I could verify the apple boot picker was to hold option. I had been putting this off and waiting to see if it was going to come out of of beta, or if people were bricking their Macs. Your video made me bite the bullet. Also, I have a ch341a flash programmer, so I was almost thinking of backing it up first to be safe, but I didn't. I do wonder if someone bricked one, if it could be flashed with their backup dump using the programmer. I have 2 more to go, so hopefully, I won't find out the hard way.

[@MacSoundSolutions]

If you have opencore running you have to hold option for EnableGOP to load first as you have found, if you remove your opencore drive you can only boot into a supported Mac OS like Mojave and then there is no need to hold down the option key it will just boot like a regular Mac with enable gop loading the Apple boot screen. As far as Windows goes you just don’t want to boot into Windows without Opencore running, so if you are using EnableGOP via option to boot you don’t want to boot into windows but not sure you can see the windows drive to select it because we are not using bootcamp. I have not tried it myself. I should try putting Mojave in, remove opencore hold option at boot and see if windows 11 shows up, I don’t think it will because it’s a UEFI install and regular normally Macs only see legacy windows installls via boot cam so maybe it’s not even an issue. Will check this out when I have a minute,

[@louisalfred3]

Great video

[@acidtechno]

perfect what a great day

[@RichieKeane]

Hi Great video,, you mentioned you booted into windows without OpenCore, does that mean if you use parallels or bootcamp on a machine you cannot do this without rebuild or reset of PRAM after you delete the original windows boot camp set up? If you buy a 5.1 to start restoring mod would you do this first and then do boot camp?

[@MacSoundSolutions]

No I said you don’t want to boot into windows without the protection of opencore, you can brick your mac if windows writes certificates to your bootrom. With Martin Lo’s opencore package you must have a windows UEFi install of windows not legacy which boot camp is legacy, so no need for boot camp. Check out my video on installing Windows 11 on Mac Pro 5,1

[@donhowell3372]

"One More Thing" for me will be a RX6000 series GPU ... though i still run my perpetual Protools on my Mojove Boot ... i do have a another 6 core classic macpro that I'll setup as Protools only in mojove and use my RX Vega56 in it .. then the 12 core cMP will be Monterey Beast mode for editing video Davinci and FCP

so you had no EnableGop directory on your desktop, you did: cd desktop, when you add a space the next path is an argument, in this case, a useless.

[@MacSoundSolutions]

Telling me I look like Jerry is no way to get an answer out of me :) but alas yes I have heard that as well as Stewart Copeland, I prefer the later. I don't use a Nvidia card, but your issue is there is no driver in Monterey for Nvidia GPUs. Opencore Legacy Patcher might install it for you in their post patches but you have to check if that is one of their listed compatible GPUs and you would have switch from ML to OCLP. I would do some digging around MacRumors forums to find out but that is a really old GPU you would be much better off with at least a AMD RX580. That's about all I can tell you...

Many thanks Lance for the incredibly interesting work. I am very interested in your opinion, in order to mount video in 4k on a MacPro 5.1, will the Radeon RX6600XT 8gig video card be noticeably better than the Radeon RX5700XT -8Gig? Could the Radeon RX6800XT be significantly better for this? Thank you again.

[@MacSoundSolutions]

Not a huge difference between a 6600 and 5700xt the 5700xt doesn’t need to be patched to get it to work in the 5,1. If you want to game in 4K then the 6800xt is your best bet but you have to do the pixlas mod and it needs to be patched. I have videos on this. A rx6800 non xt does not need the pixlas mod but does need to be patched.

Thanks for sharing, I always followed your advice since I got HD7970 a long time ago. Can you specify which OpenCore parameters to protect Windows from writing something to boot ROM? or the Martin Lo's OC already protect it? I have another SSD running Windows, but I don't know if I am on the safe way to run it back and forth. and... Can I say the deep PRAM reset (3 more times) is the way to clear garbage collection or is similar to the reconstruction to make a ROM back in good shape? Thanks in advance.

[@macschrauber1982]

the forced garbage collection will clear more than a normal nvram reset, sometimes the lucky ones get a Microsoft certificate away with it. But it is not like a reconstruction. With a reconstruction you will get a completely empty NVRAM like the machine had before booting the very 1st time at day 1 of its life.

[@MacSoundSolutions]

Martins package protects you so no issue, best to backup your rom and have a look, send it out to Macschrauber to give you a nice clean fresh one if needed. You can move Your Microsoft folder to the windows drive efi, which is a good idea so you don’t delete it by mistake when updating opencore. Also good to backup that folder, it tells opencore that you have a windows install if you delete that folder Opencore won’t see your windows drive to be able to select it in the OC bootpicker

Many thanks for this very clear video. I followed the instructions step by step, and everything worked well on my MacPro 5.1 early 2009 2x3.46, as long as I kept my old ATI Radeon card. I was able to boot under Monterey (OCLP). However, as soon as I switched to the RX580 Pulse Sapphire Dual BIOS, I experienced what another user refers to as a 'neon pixel stripe rain' on both the startup and boot screen. This issue persists when I choose the hard drive with Monterey installed, but it disappears when I select my backup disk under Catalina. I set the dual BIOS switch to the right on the RX580, which I believe is the gaming position, but it didn't change anything. The only thing I haven't touched is the SIP; I don't know if that could be the reason. Has anyone had a similar experience? Should I reflash my ROM since I switched the card? I'm a bit lost and would like to avoid potentially bricking my machine with a risky manipulation. Thank you for your insights. Clement

[@MacSoundSolutions]

Did you install the latest version 1.4? I have heard RadeonVII get weird lines on boot screen but not rx580. Is the GPU running its stock BIOS? I would reach out to MacSchrauber he may have some info. Did you try both bios switch positions?

No it’s not related as macschrauber says, you have to get a 4,1 to be a 5,1 first before doing the enable gop update.

[@macschrauber1982]

If you boot a Windows NVMe (hence its a NVMe it has to be UEFI) unprotected you will get your bootrom signed with a certificate. This will harm it in the long run. So the advice to remove it. Other option: Check bootorder in the Dumper log. OpenCore needs to be at first position. IF you reset the nvram and the ESP of the NVMe is the first the firmware finds it will start it and sign the bootrom. That's the concern, and that's why its safe to remove it. And just onther hint: remove or rename the boot.efi file of Window's ESP. OpenCore starts it anyway - and unless it's not replaced by an Windows update or repair action Uefi Windows will not boot without OpenCore. That's the goal to keep the bootrom healthy.

If I am going to now inject using the dosdude tool, should I use the most recently rom back up with less space or revert to the earlier one with more space or does it matter? Thanks

I would go with the most recent every reboot changes the numbers and it will purge itself when it gets full. Always a good idea to have MacSchrauber have a look at your rom before flashing, I am not a rom expert at all and if it’s a 2009 4,1 -5,1 Mac Pro they are more prone to rom issues.

SIP has nothing to do with loading a Gop driver in firmware. You can set it back on. It was just needed to load the helper kext for Flashrom. OCLP sets sip off for kexts as they need it for their modified kexts. Thats the difference between using the Dumper with native or with OCLP driven OS.

@@gidrogen1298the 6800xt draws too much power! You either need to sell it and get a rx6800 non XT or do the pixlas mod asap. There is a good chance you are going to fry your logic board, it should just be shutting down from too much power draw. Pixlas mod is a must for the XT

[@gidrogen1298]

I have been using the RX 6800 XT for half a year now and from time to time I encounter an error where the Windows Server unexpectedly terminates. Also, when this error occurs, various defects appear on the screen. When purchasing the RX 6800 XT, I asked the seller how to connect this graphics card, and I was told to connect it in the usual way. It turns out the problem is in Pixel Mode, thank you very much for the information, without you I don't know what I would have done.@@MacSoundSolutions

@@MacSoundSolutions Where can I get the cord to connect Pixel mod? Or can I use the cord where the video card is connected?

hi Lance, I did the Bootrom flash and it works with my AMD R9 and my Nvidia GTX680 But I cant get it to work with my RX580 cards? My 580 cards do not have a physical Bios Switch.. Any ideas? "Note: the machine wont boot with and RX580 and enableGOP installed but, my RX580 cards work without enableGOP installed" Thanks!

[@MacSoundSolutions]

Could be the rom you might want to find the original cards rom and reflash it, it could be modded. Not sure though, it should work with a 580.

[@fookoo567]

​@@MacSoundSolutionsThanks Lance, I found out these 2 cards were flashed for Mining. I would try flashing them myself but I don't have a PC. tsiAlex said I could flash them with my 5,1, But windows won't boot with these cards. I'm kinda stuck!. I found a Flashing Service but its $60 a card! Ouch!

[@MacSoundSolutions]

@@fookoo567 had a feeling that could be the case, so you don’t have a friend with a PC?

[@fookoo567]

@@MacSoundSolutionssadly no.. everyone I know has a Mac LOL.. and even if it were a PC it would be a laptop

@@fookoo567 I installed Windows 7 and Windows 10 on my 2012 5,1 Mac Pro, and used it to flash my EVGA GTX 680 video card with the Apple EFI video rom for the boot menu, the process takes less then 5 minutes. DOSDUDE1 has a video on how he flashed his GTX 680 for his Mac Pro which is a similar process to using ATI Flash in the command window. The problem is the Netkas RX 580 Video rom is about 256KB for the boot menu, so you need to verify the size of your video rom by backing it up using GPU-Z in Windows, and comparing the size. If you have a Armor RX 580 Netkas has a 128KB video rom for the bootmenu.

Hi Lance, after I loaded enableGop I can’t my Mac 4,1 to work. I only get a black screen. I was able to get into recovery mode and reinstalled Sonoma but once it’s installed it keeps rebooting non stop. 4,1 was flashed to 5,1

[@MacSoundSolutions]

You can’t run Sonama without opencore legacy patcher and a supported GPU, what OS did you have before doing enable gop?

[@geovannymoreta6052]

I had Opencore legacy installed and running Sonoma before I did the enable GOP.

[@MacSoundSolutions]

@@geovannymoreta6052could be a conflict with the GPU is it a standard PC GPU or was it flashed?

[@MacSoundSolutions]

I would run opencore legacy patcher installer and maybe it will re bless opencore. If that doesn’t work pull your opencore drive and boot off a Mojave drive, you should always have that for when issues arise with OCLP. At least a bootable thumb drive, if you get the Apple boot screen then enabkeGOP is installed. They really should not conflict with each other.

[@geovannymoreta6052]

The current GPU is a flashed GPU, I also installed a standard one GPU as well. I have a Mojave bootable drive however I can only go into recovery mode and able to target disk the second HD with Sierra which I’m able to get access to. Should I remove all the drive and have only Mojave drive only and then continue from there? Thank you

[@IntroCOOLtourAL]

I just flashed 2010 and 2012 macpro 5.1 and both a now slow as hell!😢😢 What could it be?????+++++++++++++++++++

[@MacSoundSolutions]

Try a pram reset, but need more info, what OS and GPU? EnableGOP should not have anything to do with slowing things down.

@@MacSoundSolutionsopencore monterey on 2012 and some other patched catalina on 2010. I flashed back to original rom on 2012 and nothing has changed. I tried run linux and it worked fine. So i installed another monterey on second partition of the same nvme and it worked absolutely fine. That is strange, i didnt even use that disk when i was flashing it, i used disk with catalina for both.

[@IntroCOOLtourAL]

@@MacSoundSolutionsand yeah, i used pram reset at the first place, but it didnt help

[@MacSoundSolutions]

@@IntroCOOLtourAL​​⁠if Monterey worked on another partition then the issue is something else. I would send a copy of your bootrom to MacSchrauber and have him take a look at it if possible but seems it’s something else that’s the issue.
