Garmin USB not recognised on mini mac

Also tried to step down on a older Mac mini with USB2, but didn't help.

Does it require Garmin USB drivers? If so did you install them according to Garmin's instructions? Are the drivers the correct ones for your "latest OS"?

Note sure if this will help, but read my experience below.

I got a MBP Retina and had the same issue, the USB ports work with everything connected to it so far apart from the Gamrin 276C. Went the route of bootcamp and Win7, which had no problems connecting to the 276C.

I then uploaded the latest drivers from Garmin for OSX (I'm on 10.8.2) with no luck.

Eventually I figured why not try an USB hub to step down to USB 2 with the hub. Got a cheapie USB 2 hub that I plugged into the MBP, then connected the 276C to it. Worked great and have not had any issues with it since.

So it seems the USB3 ports on the new Macs and OSX may not play nice with some older USB equipment out there. If that is the case try a USB 2 hub and see, may save you a lot of time and frustration.

I'd like to upvote this solution. It worked for me too. I have an older 276C which my rMBP wasn't recognizing. Using a cheap usb2.0 hub solved my problem.

Dear MikeNoe,

I have the same problem with my garmin 278. Please let me know which USB Hub model you are using in order to buy it and solve my problem.

Many thanks.

Hi, I'm having the same problem with my MBP and my garmin 278. I'd prefer the drivers solution as I need to carry as less stuff as possible, so, have you any idea about where could I find usb drivers for mac?

Cheers!
