[HELP] OpenCore Big Sur stuck after booting the installer

[Sasha44]

@Feartech I disabled DummyPowerManagement (actually enabled it previously only for testing purpose, but it does not affect anything).
Change kext order, making Lilu.kext to be first.
Change SMBIOS to MacBookPro13,1
Reseted NVRAM, but got totally same behavior.

Also tried to use CpuTscSync.kext as after googling I found that this could fix such problem when installer freezes, but with it boot stuck on:
CpuTscSync cputs: 0 current tsc from rdtsc64() is 54884367930. Rendezvouing ...

is it your trackpad that freezes up or a usb mouse?

 

[Sasha44]

@Feartech USB mouse. But not only mouse is freezing. Installer itself freezes.

@Feartech I tested my OC setup for starting existing installed Catalina. It even does not start my Catalina which perfectly works with Clover.

Also please move thread back to Big Sur laptop support as main goal is to install Big Sur.
I just tested if installation process could be started for Monterey with current OC setup, and got almost same result as for Big Sur.
Now I created back Big Sur install media and will continue experiments on it.

If you have any ideas what I could also try in order to install Big Sur on my machine, please share your thoughts.

Are you clearing NVRAM each time before booting with a different bootloader ? If not that can cause problems like this.

 

[Sasha44]

@trs96 I am usually reset NVRAM at each boot loader change. And in case of testing Catalina with current OC setup I used for Big Sur and Monterey install, I also reseted NVRAM. And boot process stuck on:
"ALF, old data swfs_pid_enrty <ptr>, updaterules_msg <ptr> updaterules_state <ptr>boot-args = -v keepsyms=1 debug=0x100 alcid=3 -wegnoegpu chunklist-security-epoch=0 -chunklist-no-rev2-dev"

I also tried to not reset NVRAM but got same result.

Is there any news, because of your big sur / monterey installation problem?
I have the same problem with the installation of monterey (after verbose logs disappears, it freezes at apple logo)…?

Please reply me, thanks a lot!
