Tip: Slow Chrome, try this

I noticed my Chrome was chugging it after switching to opencore and upgrading to big sur.

I have an i9 and 5700xt, neither which should be a problem, but things just werent as smooth as they were on Clover+Catalina.

Try this:

  1. Go to chrome://flags
  2. Change "GPU Rasterization" to disabled.

For some reasons, and I'm not sure if it's opencore, big sur, or the version of chrome. But disabling GPU Rasterization, really put a stop to some chugging I was experiencing.

I just have one problem.... =/

When i turn on my Wi-Fi, my bluetooth goes wild and theres a lot of interference (on bluetooth side) and i cannot use 5G Wi-Fi (returns password incorrect error). With the Wi-Fi on, my Ethernet cable stops working too (i lost my ip and i get an Self-signed ip)

I cant use AirDrop (I didnt test messages or FaceTime, but AppStore works)

But.... everything else is working!! I even uploaded some iOS builds to TestFlight some days ago

Can someone help me fix audio on my dell latitude e6500?

I installed macos high sierra 10.13.6 on dell latitude e6500(intel c2d p8700,4gb ram, nvidia quadro nvs160m,idt92hd71 audio) and everything is fine except audio. I got patched applehda for my idt92hd71 and also got hdaenabler in my efi folder and s/l/e folder. Set layout id in config.plist to 13 which is default by this patched applehda and also applied dsdt patch for idt92hd71 that i read somewhere that i need. It detects audio output and detects when i plugin headphones in but no audio is coming out from speakers or from headphones. How can i fix this?

I did some searching on here on the above card but could not find any suitable answers. Has anyone managed to get this card working with Big Sur 11.5 as yet. I got myself one today and it boots BS but Graphics Acceleration is only 5mb so makes it unusable.

Dell Optiplex 3040 Shuts down after installer boots

Dell Optiplex 3040 Shuts down after installer boots

So I have a dell optiplex 3040 here that i've been trying to get mojave going on for a few days now, and so far as far as i can get the installer to boot is seemingly all the way through, it goes to a white screen with a movable mouse, and then an apple logo with a bar that goes to about 95% before freezing, and then a minute or two later the machine just powers off. No reboot, no panic, it just shuts down. Any ideas?

CPU: i5-6500

GPU:MSI GT 710 1GB / Integrated Intel HD 530 (not used)


Model: Optiplex 3040 SFF

EDIT: Realized i had appleDebug set to false. Enabled that and it shows this now before shutting down:

Dell XPS 15 7590 freezes during macOS install

Hello everybody,

Need some help troubleshooting a freezing issue. I can boot from the USB and reach the macOS recovery/install screen. It either will freeze right away or I can get through formatting my disk through Disk Utility and start running the installer until it freezes a few minutes in.

CPU - i7-9750H

GPU - Intel iGPU UHD 630

RAM - 16 GB DDR4

SSD: Samsung 970 Evo NVME

Laptop Model - Dell XPS 15 7590

I am using the files provided by pmdevita (

Per the instructions I've used GenSMBIOS and created new SMBIOS keys for my config.plist as well as removed "brcmfx-aspm" property and enabled the "AppleXcpmCfgLock"

OpenCore Log File - (

Any advice greatly appreciated.

I'm getting "Please connect to power before continuing updates" when trying to update to Big Sur 11.5.1. I'm running Big Sur 11.5 on a Ryzen Hackintosh in QEMU/KVM with OpenCore. Am I missing something related to power management? Is there a way to disable this?
