We've posted before about GPS maker Garmin's rather tortured relationship to its Mac customers, only delivering Mac compatible software a long time after promised (Training Center) or not at all (MapSource). However, it looks like things are getting better. After finally delivering Training Center back in January, Garmin has now graced us with two new Mac betas. The POI Loader "allows you to load custom points of interest into your unit" from your Mac. And the WebUpdater for Mac lets you update the firmware in your Garmin GPS device. Now if they'd finally get MapSource on the Mac, we might consider cutting them some slack.
