Do any of you guys use a Mac to update your built in GPS?

Not using RM, but I am using an older MacMini w/OS X 10.6 and Garmin. Went to update it a couple weeks ago and got a message saying that the updater would no longer support 10.6. Needed to upgrade to Lion 10.7. Cost me $20.
Had to wait 2 days for the download link to my email. Installed flawlessly. Everything backed up and restored perfectly. Even reopened the browser to the same pages I had open previously. GPS updates now, no problem

Ditto. The only Mac I have that will run Yosemite build is my MacBook. All of my other Macs are vintage, some over thirteen years old. Yet they all run SOME version of Mac OS X. The same can't be said for Windows boxes. And yes, my MacBook also runs Windows and Mac OS X simultaneously, so for the very few processes that i can't do with Max OS X, I can do on Windows.

My bet is that the OP is experiencing a problem with the adapter between the GPS unit and the laptop. Some serial to USB adapters are a bit wanky.
