Installing Dual Boot Debian 12 on MacBook Pro (2019) Intel T2: Resolving Volume Hash Mismatch Issue
Upgrading from macOS Catalina to Ventura can sometimes result in a Volume Hash Mismatch issue. This problem can persist even after several upgrades and re-installations. In this article, we will guide you through the process of installing Debian 12 alongside macOS on a MacBook Pro (2019) with an Intel T2 chip, while addressing the Volume Hash Mismatch issue.
Prerequisites
- A MacBook Pro (2019) with an Intel T2 chip
- A USB drive with at least 8GB of storage
- Debian 12 ISO image
Creating a Bootable USB Drive
To create a bootable USB drive, you can use a tool like Etcher. Download and install the application, then insert the USB drive and follow these steps:
- Select the Debian 12 ISO image
- Choose the USB drive as the target
- Click "Flash!" to create the bootable USB drive
Preparing the Mac for Dual Boot
Before installing Debian, you need to prepare your Mac by doing the following:
- Restart your Mac and hold down the Option key to enter the Startup Manager
- Insert the bootable USB drive and select it as the startup disk
- Once the USB drive boots, open the Terminal application
Resolving the Volume Hash Mismatch Issue
To resolve the Volume Hash Mismatch issue, you need to disable the SIP (System Integrity Protection) and reset the NVRAM (Non-Volatile Random-Access Memory). Here's how:
- In the Terminal, run the following command to disable SIP:
csrutil disable - Restart your Mac and immediately hold down the Command + Option + P + R keys to reset the NVRAM
- Once your Mac restarts, re-enable SIP by running the following command in the Terminal:
csrutil enable
Installing Debian 12
Now that the Volume Hash Mismatch issue is resolved, you can proceed to install Debian 12:
- In the Terminal, run the following command to partition the disk:
fdisk -l - Create a new partition for Debian by running the following command:
fdisk /dev/disk0 - Follow the on-screen instructions to create a new partition
- Format the new partition by running the following command:
mkfs.ext4 /dev/disk0s4 - Mount the new partition by running the following command:
mount /dev/disk0s4 /mnt - Install the base system by running the following command:
debootstrap --arch amd64 sid /mnt http://ftp.debian.org/debian - Chroot into the new system by running the following command:
chroot /mnt - Configure the system by setting the timezone, locale, and keyboard layout
- Install a bootloader by running the following command:
apt-get install grub-efi-amd64 - Generate the GRUB configuration file by running the following command:
grub-mkconfig -o /boot/grub/grub.cfg - Exit the chroot environment and unmount the new partition
- Restart your Mac and hold down the Option key to enter the Startup Manager
- Select the Debian partition as the startup disk
In this article, we have covered the process of installing Debian 12 on a MacBook Pro (2019) with an Intel T2 chip, while addressing the Volume Hash Mismatch issue. This includes creating a bootable USB drive, preparing the Mac for dual boot, resolving the Volume Hash Mismatch issue, and installing Debian 12. By following these steps, you can enjoy the benefits of a dual boot system with both macOS and Debian 12.
