instructions for switching and upgrading using OCLP going forward?

macOS 11 Big Sur on Unsupported Macs Thread

The 2012 MBP is fully supported by OCLP. I think it is worthwhile switching over to OCLP because of simplicity of OTA afterwards. You might think OCLP is complicated but it is straight forward in operations especially for models fully supported. When I switched to OCLP, it was not that hard: -...

Hi all, after update my Mac Pro 3.1 to Big Sur 11.3 (OCLP 0.1.1 & 0.1.2), I have many freeze during the boot.
The only solution is to power off the Mac Pro 3.1 and power on it again many times until it boot to the Big Sur login screen.

I miss something? With BS 11.2.3 all work flawless.

Any suggestion?

Thanks

Opencore Legacy Patcher

Previously used barrykn's patcher to install 11, 11.1, and 11.2 on a 2012 macmini. Does that still work for 11.3.1?

Can someone point me in the direction of instructions for switching and upgrading using OCLP going forward?

change to use Patched-Sur just one click and it will do all for you, no need any usb drive.

BarryKN's 0.5.1 micropatcher still works as before. Can't advise you on OCLP install, but there are plenty of examples here on the forum. Might search for users who have been successful recently. I'm told that the instructions at GitHub are good.

I had successfully installed OS 11.2.3 with OCLP 0.1.1. I am getting native updates through System Preferences Software Updates. I had previously tried to update to OSv11.3, but corrupted my SSD. Do native updates work better now that OSv11.3.1 is available? Thanks for any input.

Hi all - I have updated my iMac with the new OCLP and 11.3.1.

All works fine however I get no airplay audio or mirroring? Looking online it looks to be because the Metal Headless mode is disabled but can't work out how to enable this? I have a K610m graphics card and pulling my hair out any ideas?

Hello everyone, we're proud to release OpenCore Legacy Patcher v0.1.2!

  • Currently requires wired connection, wireless highly unstable
• Windows 10 PCI Allocation patches for UEFI
  • Enhanced Audio and eGPU Support
• Enhanced 3rd Party NVMe
  • Allowing for up-to 90% power reduction at idle on non-Apple drives
• Support for Native Macs, allowing better 3rd Party Hardware support
  • Includes 3rd Party NVMe Patches as well as Sidecar support

Hi There,

I have updated to 11.3.1 on iMac 12,2 with K610M graphics careened OCLP 0.1.2.

I connect my iPad 7 via usb -> listening - trust it etc and then enable sidecar but the screen goes black. If I go to sidecar setting and move Sierra from left to right this then appears but the screen is still black. Interestingly the keyboard off the sidebar works typing on the Mac... an ideas why I'm not getting video output?

Cheers

You have no supported iGPU, Sidecar requires either a T2 or Metal-based Intel iGPU to operate

macOS 11.4 Beta 2 (20F5055c) has been seeded to developer channels. No InstallAssistant provided yet as usual

How can I get a supported igpu or is it not possible on a iMac 12,2 ? Is this linked to why I’m not having airplay work either?

Both are most likely related, as Nvidia has limited hardware decoding support. You'd want to get an AMD Polaris GPU

Regarding upgrading to a Metal iGPU, you'd need to figure out how to install an Ivy Bridge CPU into your iMac. Haven't looked myself, though I believe there's been some experiments before

Great thanks for the prompt response now the pater supports legacy opengl cards if I got and anti 4xxx series and put it back in I guess AirPlay would work again as it did in Catalina?

Hi, could you open an issue on Github regarding this? Forums are an absolute pain to keep track of issues from our end, so having a consolidated area is much appreciated. When you open the issue on Github, please upload an IOReg of your machine (file -> SaveAs):

https://github.com/khronokernel/IORegistryClone/blob/master/ioreg-210.zip?raw=true

Thanks in advance,

Thanks a lot for your respond! Sorry I didn't check this thread after I posted that, so I didn't went on GitHub to open an issue, but I've seen that in the latest release of OCLP 0.1.2 you added, specifically regarding my iMac model:

- "Fix accidentally disabling non-existent iGPU in iMac11,2"
- "Probe hardware for Backlight pathing on iMac10,1, iMac11,x and iMac12,x with Metal GPUs"

I've tried to rebuild OC with new OCLP 0.1.2 and now I can happily report that everything works beautifully fine on my machine, backlight control included! 👌

I also upgraded from macOS 11.3 to 11.3.1 via OTA using integrated System Upgrade and... it worked!
It got stuck a couple times when rebooting: first time with white loading bar 100% full, second time with loading bar 50% full. Both times I switched it off manually, then on reboot it continued normally with its things, and eventually got me to set up assistant and desktop.
My PSU got really hot during the updating process (I think mainly because of my custom CPU/GPU configuration), but when I entered my desktop and Macs Fan Control kicked in, everything returned slowly back to normal.

My machine correctly spoofs iMacPro 1,1 (in finder from desktop if I click on "help" I have as an option "learn to know your iMac Pro"... yeah I'd love to, if only I had one lol), OCLP detected my upgraded Wi-Fi/Bluetooth card and whitelisted the system correctly (AirDrop and Continuity/Handoff are working great), graphics acceleration works really nicely, I have SIP and SecureBoot turned on, it's like a dream coming true!

Thanks a lot to all of you involved in this amazing project!

You have a similarly specd setup to me. Do you get air play mirroring or audio?

Just had a read that seems more for continuity and handoff not airplay

 

[b4db0y]

everything works through the new airport card and the change of settings, without the new airport the new functions do not work

Hey everyone, sorry if this has been asked and answered already. I've checked the first post here and the the OCLP GitHub docs and couldn't find the answer so I figured I'd ask.

I'm a little behind with my OTA update to 11.3.1 (5 mins remaining as I'm typing this) but I also saw the post that OCLP pushed an update to 0.1.2.

My question is: as we're going through and receiving the OTA macOS updates, should we also be downloading/updating OCLP on the internal macOS EFI partition (basically jumping to the 'Booting without USB' section of the docs)? Is that necessary, helpful, expected?

My initial thought was that it can't hurt, but figured I'd ask in case others were thinking the same thing.

Thanks.

The 1st page of this thread has a list of metal GPUs compatible with the iMac. My signature mentions one of them. cheers

 

[mwidjaya]

should we also be downloading/updating OCLP on the internal macOS EFI partition

My take is that, it is not necessary.

The older OCLP version you used was/is successful for your specific mac configuration and you can stay at that.

OCLP is being worked on by dortania team to address bugs and make improvements to support other mac configurations. Newer versions incorporate these changes.

You can update your EFI to latest OCLP at anytime, if you like. Fingers crossed, the latest version does not break anything on your already working patch.

So to be completely honest, OCLP is very much a set and forget. Generally there's no reason to update unless you either see a feature you like or have a bug fixed you experienced. Otherwise, you could honestly use the same OCLP build from now till macOS 12's release, assuming Apple doesn't pull a curve ball and break something.

OCLP's designed in a way that it should be out of the way from the user when they don't want to see it. No extra background processes for checking updates, no 3rd party programs to install new updates, etc. Just use macOS as you'd expect.
