Pre-prequisites

• MacOS 11.6 (BigSur)
• HP Connectivity Kit Build: 2.1.14425 (2020 1 16) installed
• System Preferences -> Security & Privacy -> Input Monitoring - give permission to Terminal and HP Connectivity Kit.app
• A USB-2 hub
  

The USB-2 hub is vital - the upgrade would not work at all when directly connected to a USB3 port or a USB3 hub. This is a known bug.

Install steps

• Download the 2021.10.01 firmware from https://www.hpcalc.org/details/7783
• Upzip it and copy the contents into the "Documents:HP Connectivity Kit:Firmware:PrimeG2" folder. Copy just the individual files not any enclosing folder that may have resulted from the unzip. Delete any previous files that might be there already, first.
• Connect the Prime to the Mac by USB cable (remembering to go through the USB2 hub)
• Start the HP Connectivity Kit and it should more or less immediately display a popup dialog asking if you want to upgrade to the 2021.10.01 version. Say yes and wait
  

The upgrade should be quite quick - less than a minute to transfer the firmware (during which the Prime will display a "Do not disconnect" warning) and then 30 seconds or so to update the firmware on the Prime (during which a 3 row progress bar chart is shown).

If the calc appears to do nothing, locks up or goes back to input mode (so you can enter numbers on the keyboard for example) then you have gone wrong.

Thanks a million, Bruce!
Your process worked fine for me and my G2 Prime, from my MacBook Pro.
