I'm trying to set up a new Mac mini with A Logitech K350 keyboard. Since the mini has no cd drive its not possible to load the keyboard software. Is there a work around?
One way is to use an external CD drive - I have several that work via USB just as well as an internal CD drive.
Another way is to download the drivers. I'm assuming you've tried this and - given the keyboard is Logitech - the drivers may only be available to Windows platforms. There are several ways to run Windows applications on a Mac, although I'm not sure how well these solutions work for drivers.
On another pc
Boot a linux live media, insert the software CD and copy its contents. Insert the software media on your machine and install it.
Download the drivers
External usb drives work wonders.
