Setting up a 2011 MacMini in 2021 – Software

The previous post briefly pointed out the hardware configuration and motivation behind setting up a 2011 MacMini Server as a new desktop system. I now highlight the various configuration decision and challenges (if any).

Bluetooth Keyboard and Trackpad

The first thing to remove from the setup was wires. It was mentioned in the previous post that i did the initial setup using a wired keyboard. However, once the system was completely updated using APT, i set out to pair my Mac keyboard and Trackpad. The process kinda works.

However, a few days later, problems begin to show. They are

From Part 2 when I last left off, I was really having issues trying to get the Palm to communicate with my Linux system at the full speed. 19200bps was the fastest I could go but I just couldn’t go 115200bps.

So the idea to actually modify the Palm serial port into a connector started to take root. The key idea is to look for a space on the Palm, solder the connector and have that connected permanently on the Palm, so that when required, an add-on board can be used to expand the capability of the unit, instead of mucking around with the 10-pin port.
