How do I use my RDX removable hard disk drive on a Mac OSX system?
The RDX USB drive will work on Mac OSX systems without any additional driver installation. Simply plug the media storage drive USB into an available USB port. The RDX USB should be able to be accessed through the “Disk Utility” application after plugging in and powering up. (Under the “Finder” application, select Applications->Utilities->Disk Utility.) If using a default (NTFS) formatted cartridge, you will need to reformat for MAC OS Extended (HFS+.) Specific instructions for Mac Formatting may be found here.
