#### 1.1 Partition the SSD and install m1n1

Following the instructions on the wiki, I prepared the partitions and install m1n1:

_TODO Find my notes about partitioning_
List disks and partitions:
```
eramon@cider dev % diskutil list

5: APFS Volume ⁨Data⁩ 13.5 GB disk3s5
6: APFS Volume ⁨VM⁩ 20.5 KB disk3s6
```
Following the documentation, I resize the APFS container:
```
eramon@cider ~ % diskutil apfs resizeContainer disk0s2 150GB
```
Run diskutil again, and see if it worked:
```
eramon@cider ~ % diskutil list
/dev/disk0 (internal):

```
There was now some free space now after the disk0s2. At this point I tried to restart, the MacBook was rebooting without any problem, so at least we didn't break anything with the resizing.

#### 1.2 Install m1n1

_TODO Find my notes about running the asahi installer_
Run the asahi installer:
```
eramon@cider asahi % curl -L https://mrcn.st/alxsh | sh
```
At some point, the user is prompted to say if the advanced options should be displayed:
```
By default, this installer will hide certain advanced options that
are only useful for developers. You can enable expert mode to show them.
» Enable expert mode? (y/N):
```
Choose YES. A little further below, information about the partitions is displayed, and the installer asks what to do:
```
Partitions in system disk (disk0):
1: APFS [Macintosh HD] (150.00 GB, 6 volumes)
OS: [B*] [Macintosh HD] macOS v12.3 [disk3s1, 46277907-5BF2-4627-9192-9C780B38A30A]
2: (free space: 95.11 GB)
3: APFS (System Recovery) (5.37 GB, 2 volumes)
OS: [ ] recoveryOS v12.3 [Primary recoveryOS]
[B ] = Booted OS, [R ] = Booted recovery, [? ] = Unknown
[ *] = Default boot volume
Using OS 'Macintosh HD' (disk3s1) for machine authentication.
Choose what to do:
f: Install an OS into free space
r: Resize an existing partition to make space for a new OS
q: Quit without doing anything
» Action (f): f
```
Choose "f": _Install an OS into free space_

When asked about _which OS to install_, I selected the third option, to install just the m1n1 in proxy: no u-boot, no asahi linux. Yet. I did this since I wanted to play around with the m1n1 binary booting a kernel manually. I wasn't counting with a damaged system, which is what happened next.

## _AFTER the damage_

<p>After the incident, the boot menu did not appear anymore when hold-pressing the power button, apparently it was also damaged. When booting the system the Asahi logo would greet me, followed for the m1n1 in proxy mode. I couldn&rsquo;t get anywhere else but there.</p>
<p>At this point, what was I intending to achieve? Even if it wasn&rsquo;t that clear to me how, the idea I got in mind was the following:</p>
