Forerunner 15 with latest firmware update
OS X Yosemite 10.10
I've reinstalled express and rebooted my computer. When I try to sync my data, most of the uploads result in error. At the end of the sync a dialog says "Sorry, some files from this device couldn't be synced with Garmin Connect. Any help would be nice. Thanks.
Update:
Meant to post this in the Mac forum.
