I am looking for a compact travel router that I can use to always appear in my home country when I am travelling. This router should have a killswitch if the VPN is disconnected so as to avoid leaking my location.

Hi, I am currently running Big Sur in my MacBook Pro 2014 which is the latest OS supported by Apple (and I don't know for how long they will) I have used Open Core Legacy Patcher before and ran Monterey with it, and then upgraded to Ventura, I wasn't happy with the end result because Ventura was pretty fresh by the time and in order to find a cleanest version I rolled back to Big Sur.

Now I am dealing with some issues when my Mac is on battery (which was replaced recently), and a fresh install of Big Sur didn't help, so now I am thinking about upgrading it again in order to do some troubleshooting, now that Sonoma is almost on the table (actually haven't checked if it is coming for this model).

If you have a this or similar model what would you recommend?
