High wattage 19.5V 7.4mm are usually harder to find. Most common are 65W chargers.

HP uses two different voltages for the 7.4mm black tipped chargers: 19V and 19.5V. Not sure if both will work with the latest gen mini PCs but 19V chargers will work for these. I've had a hard time looking for 120W 19.5W chargers that 705 G1 minis used that I had to resorted to using 19V ones.

Their laptops use the smaller 4.5mm blue tipped chargers. Makes sense since these laptops are too thin.

Xcode has an iOS simulator. You can have a macOS VM run xcode.

I have an extensive config inclduing vlans, plugins, policies, suricata, VPN, routes, gateways, HAProxy, etc.

When you have an extensive config, you should always test the upgrade on a "lab" machine before applying them to your "production" environment. You don't just apply the update blindly and hope nothing breaks.
