Naga on Mac can't modify

Hello, I have a Razer Naga Epic Chroma and an iMac. In a computer game I have my hotbars set up as: [1] [2] [3] [Shift+1] [Shift+2] [Shift+3] When I press 1 on the Naga the hotbar [1] fires. When I press Shift on my keyboard and 1 on the Naga the hotbar [1] fires. It should be [Shift+1]. When I press Shift and 1 on my keyboard [Shift+1] fires. I can set up a keymap and switch between 1 and shift+1 keybindings on the naga, but I want to physically press shift on the keyboard. When I use the keymap, I can't tell which mapping is active and end up firing the wrong ability. The iMac seems to be recognising the mouse as a seperate keyboard. When I go into my Keyboard Modifier settings it lists the Naga Epic Chroma. In a text field, if I press shift+1 on my keyboard "!" is typed. But if I press shift on the keyboard and 1 on the Naga "1" is typed. Is there a way to set up the Naga mouse so that the Mac doesn't recognise it as a seperate keyboard? Alternatively, is there a way to set up the keymaps so they change when I hold Shift on my apple keyboard? Thanks for the help!
