I've been trying MX Linux 23.1 current with Fluxbox...from USB sticks.
Using the LibreWolf browser (based on Firefox)..as its quite small.
On both my iMacs 5,1 and 10,1.
It has three menu systems and with one of them appearing with a right click on the desktop, I've cleared everything off for a clean look..with a pop up dock if required.
It has a range of conky options ..one of which displays the Airflow 1 (TA0P) temperature. Linux seems somewhat lacking for my iMacs fan control but there is Sensor built in for a fuller check on temps and fan speeds.
The USB stick maker will include any additional software or docs if one doesn't use a MX iso..giving the choice of making a stick with a copy of your current set up or having a default clean setup by using a iso...which is neat as I can experiment with system adjustments and easily get back to default if I muck or clutter things up.
I'm still trying to find a solution that works on my iMacs for fan control..want to speed up the minimum speeds of cpu, HDD and optical drive fans to prevent the GPU getting too hot.
