Mac OS X and Computrainer

Zwift works fine on my old (2008) 17" MacBook Pro.

4GB Ram, 512 MB Graphics card

FTDI adaptor (which works ok with PC and Ergvideo stuff) , ANT+ for cadence from Powertap Pro, and Garmin ANT+ HR strap.

 

However, when I try to run the same setup on my newer 15" Retina Macbook Pro, the Computrainer cannot be found/seen in order to connect. The ANT+ devices are all ok.

The different I thought was that the newer machine was USB3.

I found a later version FTDI driver on their web site for OS X 10.9 and above. Installed it and on the first time in Swift the Computrainer was seen on Com0, however it didn’t connect. The computer hung with a BBOD.

Upon restarting there has been nothing on the computrainer side after many different attempts of swopping USB ports, starting up in different sequences, etc. The ANT + stuff are all still ok.

Any  assistance is welcome.

I should note that I did not uninstall the older FTDI drivers before installing the later one (FTDIUSBSerialDriver_v2_3.dmg) because I do not know how to do so. Perhaps this is the problem?

Thanks

Problem solved.

I found out that the Suunto Moveslink s/w for Movescount was hogging the COM port. 

Once I quit the Moveslink app the Computrainer connected and now everything works well.

The superior graphics on the Retina Macbook Pro made getting this issue sorted out worth the effort.
