BU-353S4 and Apple OS X Yosemite
« on: October 17, 2014, 01:43:42 pm »

Thanks for welcoming me onto the board.

I performed a clean install of OS 10.10 on a MacBookPro last night with no issues. 

The USB BU-353S4 is no longer visible in the system report and the only options when running the GPS utility are Bluetooth.  The LED status lights do not illuminate. 
I have removed prolificusbserial and re-installed PL2303_1.5.1_20130822

Thanks for looking into this.

// John

We've currently finished our testing of the Mac OS 10.10 (Yosemite) and our latest 10.6 OSX USB to Serial drivers. The tested drivers have been added to our driver link on our website here:

The testing has validated that the drivers are working properly on the latest Mac 10.10 (Yosemite) update.
