So, I purchased an older MacBook from work - that has been my own for 4 year, and was specced well with SSD.

Preparing the MacBook Firmware/T2

I has had some problems with removing the activation lock and even do an Internet recovery (that just failed with 1008F Error). but when the MACOS finally was cleanly installed, make sure to enable USB Boot, as this:

...

I had a lot of trouble actually getting the danm thing to boot, but on a stick with Ubuntu 22.04 (used Balena Etcher), it finally did.

But, the Mac Keyboard was not working, but I got hold of an eternal keyboard - and that worked.

I had a lot of problemes getting to use the disk, several times the installer just crashed and restarted, and stopped with "Intallaling Installing grub on taget device failed"

But I finally gut got the installer to remove remove all partitions and install, with "Use customer custom partitions" - make sure to whipe and erasa erase all on the disk. 

After the install af the "df -h" command told me that only 100 GB of the disk was used used - I have no clue why the installer sets it up this way..


But the fix - first examine:fix was eady - first examine the LVM:

Ubuntu is installed and the complete SSD Disk installedused.

Docker install

Lets install docker.io:

...

Tip

First, I put all docker stuff in /opt 


Creating the needed Directory and the config file:

Kodeblok
mkdir /opt/frigate
vi /opt/frigate/config

...

Tip

In short, the file sets up three cams (Reolink) - using:

  • The Lowres RTSP stream for the Detect role (sub) as generally recommended.
  • The highres RTSP stream for the Recording Role (Main) as generally recommended.
  • The tracking of persons and cars
  • The use of a Coral stick for Object processing.

...

This should start Frigate and show it on http://10.0.0.164:5000:


If the interface is not up, troubleshoot the logs with:
