Will not start up on iMac 27

When I load the program I get the Ant+ message to make sure you have a dongle then i hear the music after this the mac locks up and needs to be restarted

cannot use!


Hi Nathan, that doesn’t sound fun. Sorry about that. I checked your profile and it seems like you are running on a mac laptop.  Is that not the case?  Assuming you have 2 macs, can you share the specs of the iMac 27?  GPU, processor, OSX version?



Hi, I have the same problem and I’m very interested to know what’s going on.

I have an iMac 27. CPU = 2,66 GHz Intel Core i5

RAM = 12 Go 1067 MHz DDR3

graphics = ATI Radeon HD 4850 512 Mo

OSX Yosemite v. 10.10.5



I have the same exact mac with the same exact problem.  Seems like there are several mac users that have this same problem.  Thanks for anything you can do.
