I finally upgraded to OS X 10.10 on my trusty work MacBook Air, after sticking with 10.8 because I’m just too busy and dependent on my laptop to do without it for the upgrade.
(By the way: When you work at place like I do, you don’t just update your own OS; you have lots of security related tools involved and you leave it to the experts, per both policy and pragmatism.)
So anyway, I wondered in a waiting room today what it would take to get the fancy Instant Hotspot feature to work with the iPad I also carry around. Turns out, you just select the iPad from the WiFi list, then magic intarnet happens. Huh, that was easy. Nice!
Now I just need 10.10.4 so Molly can print reliably at the house, since that whole situation appears to be suffering from the discoveryd madness.
