Please turn on verbose mode in Config.plist by adding -v in boot-args then send the picture when it is stuck

-v is already added there but nothing is showing.
keepsyms=1 alcdelay=1000 -v or should I add it like this boot-args -v. I tried both but no log is showing up.

Hhmm that's very odd. Is it the latest release of my EFI? Because i tested it on my USB and it worked and showed the logs and went into the installer. Use the source code zip file in the release page. If the latest one doesn't boot try the older one.
Please see my Config.plist

I managed to show logs. Here is a snippet of the log. This shows for about 30 secs then a lot of logs that are too quick to catch and then moves on to boot logo and freezes. I also tried using older versions but no luck.
N:B: I am trying to install Big-Sur 11.2.1.
Bios version: JBET73WW (1.37) . Is my bios version ok?

I have tried to install catalina today and got this error. Hope this gives you a clue on what's going on.

I think i know the issue. I switched to OpenHFSPlus.efi in this release instead of thr regular HFSPlus.efi. Let me revert to the old HFSPlus.efi and you can test if it works

from lenovo-thinkpad-t450-t450s-hackintosh-guide-opencore.

Ok i think I've fixed it. It boots the Catalina installer now (haven't put Big Sur in my USB yet but it should work). I'll push it and you can test if it works

from lenovo-thinkpad-t450-t450s-hackintosh-guide-opencore.

Hello, I seem to be having the same issue with Big Sur. It stops at the exact same place as the OP in his original post. I have tried replacing the EFI folder with the updated files you pushed, but it still gets stuck in the same spot.

Try the one i pushed just now. There's something wrong but i can't find it. Weirdly the installer boot on my laptop

from lenovo-thinkpad-t450-t450s-hackintosh-guide-opencore.

Unfortunately still the same issue. I don't have a lot of experience with MacOS, but is there a way to force a verbose load screen instead of the graphical loading bar? The verbose flag is set in the boot args just like the OP had it, but I'm assuming that's only for the OpenCore and/or XNU.

The -v flag should enable verbose screen and disable the loading bar.

It's hard for me to fix this considering it doesn't happen on my laptop. I'll look into it tomorrow.

In the meantime try this EFI i was testing with someone else who has the same problem: https://t.co/59sF1TNaeD

And use this config.plist: https://t.co/PSoYfg1NnD

You can try disabling DevirtualiseMmio quirk in Booter of Config.plist

Again, the same result. I may try just remaking the USB installer to see if that changes anything. I'm not sure if it can help at all, but here is the final frame before it jumps to the Apple loading bar and gets stuck.

Your problem is not the same as OP's. Yours gets past the first boot sequence but OP's kernel panics earlier.

Does it show any text when it's stuck on the Apple logo?

Ahh, apologies for that.
No, there is no text. However there is a mouse cursor that you can move around but the bar never progresses any further. I've left it there for about an hour just in case.

With CSM On hat happens (Either that or garbled screen). Turn it off from BIOS and see if it makes a difference.

So with CSM disabled it still crashes at the same place it seems, but now the apple loading bar screen looks like this. Also, would you like me to create a new ticket? I didn't mean to take over the OP's issue seeing as it isn't quite the same.
Edit: I should add I also tried both the latest EFI release and the onedrive linked version you posted here. They both resulted in the same thing.

Finally this worked (for Catalina). But, Wifi is not working and Without pendrive I can't goto MacOS. I guess these can solved easily.
BTW: Your latest update didn't work.
Thank you for the help. I don't know if it will work for Big Sur or not. So, Should I close the issue ??

from lenovo-thinkpad-t450-t450s-hackintosh-guide-opencore.

Did you use the efi as it is or did you edit the config.plist as i mentioned. I need to know which one properly works. Send tbe config.plis which is working right now.

You can easily fix this by replacing the Airportitlwm.kext in the efi with one for Catalina which is in Intel WiFi kexts folder of this repo.

Finally this worked (for Catalina).

If it worked with Catalina it should work with Big Sur.

Don't close the issue yet. I need to know if it will work with Big Sur. Can you please test it with Big Sur and report. I'll have to take down the EFI in this repo and replace it with a working one. Something might have been messed up but i can't find it

I used the EFI from this and Config.plist from this without any modification.

I am at my office right now. I will try when I get back home and let you know.

Ok, I have installed Big Sur without any issue using EFI from this and Config.plist from this

Ok. Thanks for testing. Remember to fill in Serial number and other related stuff or your Apple ID may be kicked out very often

Hey Racka, I am constantly getting Hissing sound while using headphones without any audio. I tried alc_fix but no luck. Could you please give an insight into this?

Never found a way to completely fix that. It seems like alc_fix doesn't kick in on the first boot. Putting the computer to sleep and waking it after first boot seems to fix the issue. It's a known issue with our codec

Thank you for the info. Hoping for a solid fix in the future. I will also be looking around.
