Maybe the difference is the Amd GPU is not always used on laptops (only when plugged in and heavy workload) ?
On iMacs, the intel iGPU is never used, we only rely on the amd
On your MBP, you haven’t noticed that 4K iPhone videos are read in low res in Photo ?
Chrome (or edge or other chromium browsers) are not slow to start ?
Mykola told me this problem only happens on Macs with GCN dGPU + Skylake iGPU. I think it's most likely due to the problem being related to HEVC and my MacBook doesn't support hardware HEVC encode/decode...
 
Switch from 13.5b1 zu b2 went fine on my haswell MM 7,1. Did amfipass post patch again and everything is like it should be.
My broadwell MBA 7,2 doesnˋt find OTA update 13.5b2 -neither with revert post patch nor with post patched.

OK, so the issue is real ...
My iMac (17,1) doesn't support hardware encode, but the R9 M390 was able to support HEVC hardware decode in supported Monterey.
With OCLP Ventura, videos are rendered in low res when viewing in Photos.app and most apps that are decoding videos with hardware are impacted.
It's the main issue for me.

Thank you for this suggestion. I tried this just now but sadly didn't work... my AirPods Pro 2 keeps connecting and disconnecting.

As FYI:

Funny enough, this started happening on my machine with the Apple Magic Mouse as well after updating to 13.4 using 0.6.6 Issue is system wide

Edit: Repatched with 0.6.5, issue remains. I get a feeling this is an issue related to 13.4 whatsoever since Bluetooth also disconnects without root patches installed.

Also since patching with 0.6.6 Kernelpanics seemingly related to HD4000 driver appeared:

Same for me, same machine iMac 17,1 but M395… Hope for a fix, but nevertheless wonderful work of the devs.
 
Apple systems are always focused on IQSV and the features of discrete graphics cards have long been removed from the system. But they can be returned manually.
To do this, you need to follow two steps. First, enter the commands from this list.
Here is the list of commands
And now the second step. In order for them to work, you need to create and then boot a kext, in which you need to register the properties previously removed by Apple. Here, on the example of Baffin or Elesmere.
kext_info,plist.png

There is no executable in kext, only info.plist.
It boots, I use it for my old system.
I'm afraid my poor knowledge of english will not allow me to explain this more clearly.
I'll include this kext for reference. If it suits someone, you can use it.
I just want to say that this problem is being solved and I don't think the OCLP development team should be dealing with it.
I have a question regarding the 2012-13 A1398, which uses a proprietary SATA SSD.
The speed of the SSD has noticeably decreased.
Speed_test_A1398_2012-13.png

Has anyone experienced this and may know a solution?
P.S. Some huge pictures turned out, for which I apologize, and I also apologize if this is not interesting to anyone.

Another big picture. But it shows how the kext returned the properties that I specified to the system. It is important that it contains the correct ID of your accelerator.
 
Is anyone using Citrix Workspace App successfully with OCLP patched system?
I have an iMac 11,1 and a MBP 8,1 with 13.3.1. After log in CWSA just shows me a grey screen.
Viewed grey screen too. But I tried to install Ubuntu and Windows on my Macbook Pro 7,1 (mid-2010, 13-inch) - and Citrix working on both of them. I recommend.

What I think is the problem is that it's trying to use hardware HEVC decode but it's broken, I think this mostly explains why Chrome takes a while to load, it tries to use the decoder and gives up after some time, not sure if there are any crash logs. I've gone through something similar while fixing Polaris VA.

Unfortunately there is nothing I can do to help without an affected machine.

I hope this can be fixed... for now I am using windows 11 with OCLP 0.6.7 in my mid-2011 27inch iMac because my AirPods Pro 2 works flawlessly in that system.

EDIT: Leaving this post for others who may have experienced this problem. I was able to restore proper macOS upgrade behavior (13.2.1 -> 13.4) by resetting NVRAM a few times. After resetting NVRAM, I am now seeing the 13.4 macOS upgrade after disabling "Kernel > Patch: Disable _csr_check() in _vnode_check_signature"

After resetting NVRAM, the OCLP 0.6.7b2 EFI works as-is with no changes.

===================================

My MBP6,2 is running Ventura 13.2.1 booting with OC 0.9.2, AMFI and LV Enabled, AMFIPass.kext injected. All appears to be running well for me. I noticed that after enabling AMFI and LV with the required EFI updates, I was no longer seeing prompts to upgrade from 13.2.1 -> 13.4. I isolated this to the kernel patch "Kernel > Patch: Disable _csr_check() in _vnode_check_signature" in OC config.plist. When I restore this patch (which was removed when AMFI/LV was enabled), I see 13.2.1->13.4 upgrade prompts again and permission prompts (e.g., Camera, Microphone) still work.

Is anyone else noticing this? I have reported this on Discord.

Has anyone been able to update their mac to the latest Ventura 13.5 beta 2? Did the AMFIPass Beta Test need to run again?
Thanks
I have updated all my Mac laptops to Ventura 13.5 Beta (22G5038d) without issue. I never did the AMFIPass Beta Test. I just updated to OCLP 0.6.6 and had no issue with the updating process. For me it was all a smooth update then I performed the usual root patches and was all set.

I am not technically very astute, but I believe I did. I updated OTA the same way before and after the AMFIpass beta.
 
I had the AMFIpass applied before upgrading OTA (+11Gb) to 13.5B2 (22G5038d). Upon reboot, OCLP prompted me to reinstall the post-patch which I did and so far so good. I did not take the nightly OCLP, still using the AMFIpass version. Hoping the Devs incorporate/merge it for the next nightly/version.

Upgraded from Monterey to Ventura (13.4) with latest OCLP 0.6.6 and it's running flawlessy this side on my MacPro 6,1.

Only hiccup I ran into was during the install process it would pop up with a software update error. I can't recall the exact wording, but it was pretty late in the install process after a couple of reboots.

I first did a soft shutdown and retried again, but it persisted. Eventually I found that you need to reset PRAM if this happens, so did that and the install finished. Not sure if this might be helpful to other people experiencing the same issue.

Really great keeping these old Macs going, thanks a lot!

May be we can help and support with Logs and tests from our machines?
