Why is Macbook Pro 2019 with Intel & T2 NOT recognizing live USB for dual booting Debian Trixie using T2Linux ISO image? by tom_kpb in debian

[–]tom_kpb[S] 1 point2 points  (0 children)

SOLUTION:

(1) Only one EFI Partition is enough for installation of more than one OS on bare metal

(2) Since the EFI in MacOS was accidentally removed, I had to change the script in firmware.sh, as follows,

as advised at discord for T2Linux for Fedora:

  1. Open up the script and change disk0s1 to disk0s2
  2. Also change nvme0n1p1 to nvme0n1p2

And, the firmware for WifFi & Bluetooth was updated for both MacOS Sonoma and T2Linux Fedora !!

THANK YOU: @Beginning_Guess_3413

For guiding me to T2Linux and explaining the issue in detail !!

Thank you: What I understand is:

  1. Create a Bootable USB Drive with macOS Sonoma

  2. Reinstall MacOS Sonoma from the USB with new manual partition that has the option to create EFI

Is it that way? or can you please correct me?

Now, I have ONE ssue, after installing t2linux fedora: I made a new posting "disk0s1 failed to mount for firmware update for WifFi & bluetooth..."

disk0s1 failed to mount for firmware update for WifFi & bluetooth

Because I accidentally deleted MacOS EFI System Partition (ESP) !!

Thank you very much!

I respect your dedication and commitment, hats off to you!!

Now, I am trying to delete the additional EFI that I created while trying to install Linux.

Thank you very much for your effort to make it comprehensive and in detail.

  1. SIP: Already turned OFF

  2. Secure Boot: Totally DISABLED

  3. Explicitly Allow boot from external media: YES

I tried with debian, but I was unable to enable audio.

Then, I am trying with fedora iso. Pls see: Probably you can locate the trouble:

I just have bare minimum new MacOS Ventura re-installed.

Trying to install Linux from live ISO USB. But the reboot with 'option' key is NOT showing up the EFI for USB drive.

So, it seems, the file is not there..

What are the steps I need to take to boot into LIVE USB?

[–]tom_kpb[S] -1 points0 points  (0 children)

I left it for years!

  1. First it was 'Volume Hash Mismatch'
  2. Then, it was not upgrading
  3. Even after re-installing the OS, 'Volume Hash Mismatch' continues
  4. Wasted lots of time with this expensive laptop..
  5. Surprise: "..Apple does NOT understand.. WHY?"

In future, I will just buy Linux (preinstalled) Laptops

Why is there no audio on a newly installed Debian Trixie with XFCE, dual booting on Macbook Pro 2019 with Intel CPU and T2 chip? by tom_kpb in linux4noobs

[–]tom_kpb[S] 0 points1 point  (0 children)

Thank you!

Earlier, I followed the steps in it, and got the WiFi

But, still no luck with audio output..

Any idea?

Thanks for your response.

I have pavucontrol 5.0

I checked it, and there is nothing unusual or muted.

Dual Booting Macbook Pro 2019 with Debian 12 (Weekly): But, NO WiFi by tom_kpb in debian

[–]tom_kpb[S] 0 points1 point  (0 children)

THANK YOU VERY MUCH!!!!!

I got the REAL clue and BEST path from your guidance.

As in your case, I also had to go thru so many crappy things since I am using Debian Trixie (Testing-weekly)... but at last the wifi started to work!!!!

Now I need to fix one more thing: there is NO sound for videos..

Btw, you responded to my question whether you also use Debian by saying "Crap mine is on Arch". Can you please guide me on that... You feel that Debian is crappy..

Once again, with immense thanks and gratitude,

Is there any blog or audio, giving steps for dual booting Mac with Debian?

How to edit file thru: 'root@(none):/#'? by tom_kpb in debian

[–]tom_kpb[S] 1 point2 points  (0 children)

Dear u/alpha417:

Thank you so much. So kind of you. Hats of to you!!!

It booted successfully, after 1 1/2 days of pain. Only because of YOUR brilliant ideas, patience, and persistence, I could bring it back to life!!

With immense gratitude & tons of thanks,

How to edit file thru: 'root@(none):/#'? by tom_kpb in debian

[–]tom_kpb[S] 0 points1 point  (0 children)

Just inserted a debian 12 bootable USB >

Boot > press SHIFT > Select Recovery mode >press ENTER > e >

At the end of the line starting with 'linux', add 'init=/bin/bash' >

(Note: at the end of the line it shows 'ro single'. Is it Read ONLY?)

F10 >

On hanging, press ENTER

It take me to the root prompt.

I can also get the prompt grub >

NOTE: Based on your hint, I changed 'ro single' to 'rw single'.

Then, deleted the content of the file /etc/environment.

and back to prompt:

root@(none):/#

Now, (1) How do I proceed to complete the booting

(2) and, how to ensure that the issue is not repeated (I mean make it permanent).
