MacbookPro 9.1 OCLP Bootcamp method not working

[jlnabais]

Hello all,

I followed https://dortania.github.io/OpenCore-Legacy-Patcher/WINDOWS.html for my Macbook Pro 9.1 but when running the bootcamp installer (even on windows 7 compatibility mode) I get black screen, if I go to safe mode and remove graphics drivers it works again, but obviously I would like it to work as it did in the past. I am trying to install windows 10. I tried other methods like intall using https://sourceforge.net/projects/windows-install/ but I end up always at the same point.

Does anyone have a definite guide that works with Intel and Nvidia drivers installed? I saw some threads that I should also download a more recent bootcamp installer and replace some files on windows32 drivers folder but I never get to the point of finishing the setup before my screen goes black and when I restart I get blue screen always unless I go to safe mode and delete drivers.


Note: I have done the install with internet off so windows update does not mess with it. I reset NVRAM several times also.

I personally wouldn’t recommend trying to do a UEFI installation of Windows on a MacBook Pro of that vintage. I have a 2012 MacBook Pro 9,1 and did an uneventful legacy Windows 10 installation after I had OCLP up and running MacOS Ventura. Do you have your OCLP MacOS running, and if so, which MacOS? And do your have a MacBook Pro 5,1, or is your model 9,1 - like mine?

I used the following tutorial for legacy Windows installation -LINK.

A few years ago, I attempted a UEFI Windows 10 installation on my 2012, and it was bootable, but neither audio nor Thunderbolt could work. So I haven't ever bothered with it again. Boot Camp Assistant automatically downloads the necessary Windows 10 drivers for my MBP 2012 (9,1). But Windows is bootable without them. But they're necessary for the sound card, trackpad, and my Nvidia GeForce 650M. When running Boot Camp Windows, your Intel GPU is ignored. No drivers are downloaded by the Boot Camp Assistant.

Sorry is MacBook Pro 9.1.
I have OCLP running latest macOS Seqoia ATM, does that guide work with this OS Version?

OK, then you have my MBP, or something very similar. Yes, Boot Camp Assistant should function just as it does in that guide for you. Especially if you haven't created an extra EFI partition for Windows or anything like that. If you did, because of your previous Windows install attempts, I would mount that partition and empty it. And not worry about trying to recover the 200 MB.

Once again, you have a Mac that's old enough that Windows should be installed in legacy BIOS mode. And Boot Camp Assistant knows that.

I've checked comments associated with that guide, from about 4-6 months ago. I've seen successes with Sequoia.

Although it wasn't important for me (for some reason), it's often essential that your internal DVD drive works. Is that the case? Actually, I think the guide talks about MacBook Pros (old ones) that lack DVD drives. But if yours should have one, and it now doesn't, that can make it difficult.

Provided you have a Win10 ISO, a blank DVD, and a USB drive, it should go well. BootCamp Assistant will do the "magic" that makes Windows thinks it sees an MBR partition on a UEFI disk, and the correct drivers for Windows 10 should automatically be put on the USB. If I remember correctly, it's BootCamp 6.1 drivers that are for Windows 10. I had no problems. Just followed the guide to the letter.

The USB also installs Apple Software Update for Windows, and there's about 3 updates you definitely want to install.

Inhave a disk on the DVD drive now but I have the original on an USB externam enclosure though. I need 2 ssds. One Windows one Mac os X

You may run into issues. When you reboot and hold down option and attempt to install Windows, if you see the word Windows under your DVD, all is good. Boot from It. Or for that matter, if you are lucky enough to see the word Windows underneath the icon for your USB drive, you can boot from that and install Windows successfully. But if you only see EFI under the icon, you won't be successful. I am sorry to say that if you put your internal drive in an external enclosure, you may not be able to do a legacy install from that disc. I had my DVD outside of my MBP for awhile, and it made Boot Camp installation BRUTAL. But in an OCLP environment, with my USB drive I actually had the choice between USB Windows (legacy) and EFI boot. I hope that you are lucky enough to see the same. Fingers crossed. If you don't see the word Windows anywhere underneath a boot choice, not good. The word Windows means you are about to do a legacy BIOS install.

I have never attempted Boot Camp with a separate hard drive. Just followed the guide you saw. You definitely want to erase it as MBR partition scheme, MS-DOS FAT or ExFAT. Either is OK

I decided to hook up my MBP to an external Blu Ray drive and start it up with both my Win 10 DVD and my USB drive inserted. At least with OCLP Ventura, the boot picker screen is good news - I can do a Windows 10 legacy install using either my DVD or USB drive. Hopefully, since your machine should be similar, you'll be as fortunate. You DON'T want EFI Boot in either case. See photo.

@GH1852 thanks for the feedback but my issue is not booting or installing windows I can get it installed is when running bootcamp app and when the drivers for the intel HD 4000 get installed I get blue screen or a black screen and I can only solve it by removing the drivers. Can you show mw the versions on Device Manager for the nvidia and intel hd 4000 you have installed and working? I need to be able to install bootcamp so I can have the bootcamp app working and all mac controls working on windows like it used to be when we installed bootcamp from mac.

OK, I know what you are trying to do. Even in fully supported MacOS on my machine, the iGPU has never been seen by Windows as an active device. I've been running Windows since 2016 (long before OCLP existed), and graphics switching has never been an option in Windows. It sees the dGPU.

Here's what it sees now:

When I was first using Boot Camp around 2016, the nVidia driver was a 2015 version. But graphics switching has NEVER been an option.

Why does Windows not "see" the iGPU - Apple firmware deactivates the iGPU when it detects that you are booting anything other than MacOS.

Please look at the following link, which explains and discusses workarounds-


LINK

There are hacks. One deactivates the dGPU and makes it so Windows can see the iGPU. I have not pursued that. The methods mentioned in the link involve putting something into the Windows EFI that fools the Mac into thinking it's booting into MacOS even though it's really Windows. But EFI Windows isn't even an option for me - it shuts off all audio functionality on my machine (and all Macs similar to mine), plus it shuts off the Thunderbolt port on my machine.

So you're trying to do things I've never made an attempt to try. Because I read about all the hacking involved, I chose not to pursue them. There is an advanced function in OCLP that supposedly makes it possible for Windows to see the iGPU (enable gMux), but upon looking that up on the OCLP Discord server, I learned that it isn't possible to get that to work on a MacBook Pro as old as mine.

I've told you all I know on the topic - graphics switching in Windows in Boot Camp. It's NOT "normal"

I was able to get to this point where I have only nvidia and I am not sure what that other is and I removed the HD 4000 and also I've renamed the file in drivers (system32) for the HD 4000 named "igdkmd64.sys" to "igdkmd64Backup.sys" and I can't see the issue any longer I am fighting though to have sound now. I only have it on my phones the speakers are not working and I can see a list on my audio output and if I open sound setting I can see the volume up and donw on the bar.

Also nvidia drivers from https://www.nvidia.com/en-us/drivers/details/110603/ work like a charm

@GH1852 I can't however finish a bootcamp full install without seeing the issue for the GPU. Are you able to do it?

Also I was seeing an iGPU that's the problem I think OCLP does not hide it like Apple did, am I accurate? but turning it off on device manager is not enough because when I ran bootcamp install I allways ran into the issue.

I have no problems with sound or video. And I installed Windows 10 after I installed MacOS Ventura using OCLP. Boot Camp installation was NO different than it was when I was running Mavericks through Catalina. All I did was follow the video tutorial I have already shared with you. Since you have 2 hard drives, you'd want the Windows one erased as MBR partition scheme, FAT or ExFAT - NOT GUID!. And you could bypass the part where you create a Windows partition on your MacOS hard drive.

I had no problems with OCLP making the iGPU visible to Windows. None at all. Just for the sake of transparency, I'm using OCLP 1.5.0, Ventura 13.7.4,

I can promise you that you will NOT have audio devices if you do an EFI installation of Windows 10. MBR Legacy install, yes. There's an EXTREME hack that makes the audio devices on my Mac show up in after a Windows EFI installation, but, once again, I just did a normal legacy installation, thereby avoiding hacking.

I have to add that I have no experience attempting a Boot Camp installation to a separate hard drive. I've never tried it.

One last question - OCLP recommends that you ALWAYS install the latest MacOS for the machine sometime prior to OCLP, in order to have the latest firmware for the Mac. Did you do so?

 

[jlnabais]

@GH1852 I can see audio devices and drivers FYI and when I intalled windows before any updates or drivers I had audio on my speakers, I do have audio on phones/bluethooth, only speakers not working not sure if that's what you are referring to. I haven't tried thunderbolt but it's not an issue for me. what's that "EXTREME" hack? Can you link it to me? thanks


I will most likely do the installation as Legacy BIOS and do a clean install to see if I can get bootcamp to install properly at least, since I think this is the closest I can get and I still have 4 major issues:
1) No speaker sound
2) no brightness control or any other shortcut from mac keybord working (besides volume on windows controls)
3) Trackpad controls (right click)
4) No bootcamp assistant

From what I saw if I use that method these will work.

 

[GH1852]

If you use any nVidia driver other than the one that is installed when you install the drivers that are included on your Boot Camp USB drive (WinInstall), you’ll have the brightness control problem. But there’s a very easy fix for that. Installing the other drivers on the WinInstall USB also takes care of the trackpad, audio, and installs a Boot Camp control panel for Windows. Do you have your WinInstall USB? I'm starting to think that you don't, or you haven't used it to install all the Boot Camp drivers, which take care of your 4 problems. Please let me know whether you have your USB (WinInstall) with the necessary Boot Camp drivers.

If you do a legacy (not EFI!) installation of Windows, which is definitely the way to go for a pre-2014 Mac, the EXTREME hack for audio is totally unnecessary. Do you really think it's necessary to do an EFI Windows installation? For what purpose?

No one really I was just used to the OCLP bootcamp guide which worked great on other unibody (with only hd 4000) in the past so I am used to it but I can use the method you've shared and do legacy install.

I have bootcamp drivers from apple (bootcamp 5.1.5621) and I have ran it but tbh when I do it always shows blue screen when intalling "intel hd 4000" and I can't never finish it as said above. I have ran it but never finishes, and I have ran drivers individually bit have the same problems as above. What's the "But there’s a very easy fix for that" is also installing other bootcamp drivers?

Thanks.

You haven’t answered whether you the WinInstall USB that is created by Boot Camp assistant. I need to browse mine, but I’m almost positive that you have the wrong version of Boot Camp for Windows 10. You seem to be doing everything to make Boot Camp as problematic as possible

 

[jlnabais]

How can I have the wrong version of I downloaded from Apple site and says its for that model for One and brigandeer also downloads for macbook pro 9.1?

Well maybe but not on purpose I started by following OCLP bootcamp instructions, only recently I've understand I need to do legacy boot and Install like that which I havent been able to do.

 

[jlnabais]

And yes I have created an USB with the bootcamp assistant but canceled because I don't want to Partition my OCLP drive, as I have 2 distinct SSDs. I can check what's on that USB though but I thought the process didnt finished because I've canceled that step.

 

[GH1852]

WHY are you messing around with Brigadeer? Use Boot Camp Assistant to prepare your WinInstall USB, and you’ll get what you need. My WinInstall USB does NOT attempt to install Intel HD 4000 drivers because doing that doesn’t apply to my laptop

 

[jlnabais]

I am not I used to, because as Said its the instructions I am used to and working on other MacBook pros on OCLP Bootcamp documentation, was the referente I had at the time, you have asked what I tried I am only answering. Ok Will try thanks

I could try to rerun the Boot Camp Assistant on mine. If I remember correctly, the USB is completed before anything about partitioning the hard drive is seen. Is your laptop mid 2012, unibody with nvidia 650M and Intel HD 4000? If it is, my drivers = what you should have

 

[jlnabais]

Yes that Intel and NVIDIA. Thanks

 

[GH1852]

Yes that Intel and NVIDIA. Thanks

My version of Boot Camp, downloaded by the Boot Camp Assistant in MacOS Ventura, is the following -

<ProductManufacturer>Apple Inc.</ProductManufacturer>
<ProductVersion>6.0.6136</ProductVersion>

I once mistakenly used Boot Camp 5 with Windows 10, the result was bad, and was told by Apple Support that Boot Camp 5 only was for Windows 7.

I'm about to start Boot Camp Assistant to verify that you can easily create the USB without doing anything to the internal hard drive.

 

[jlnabais]

Ah ok I see. I will try legacy boot then but might not be on upcomming days though

I was thrown off by: "MacBook Pro (Retina, Mid 2012)" on https://support.apple.com/en-us/106412
