Can't load models on a Mac


I just upgraded my operating system on my iMac to 10.10 and I can open Cetus Studio and connect to the printer and load filament.

I'm now having problems with loading my own stl files. I hit the "+" button and then the import button and nothing  happens. According to the online manual a pop up window should open to allow me to select the file I want, but this doesn't seem to happen.

Anyone got ideas on how I might go around fixing this.

I'm also having the same issue with UpStudio running on the same computer

Thanks in advance


Problem solved, 

I updated the operating system and things started to work
