Plug ins not showing

Hello. I recently installed a free plug-in (Black Mamba basses) and it does not show up in my AU instruments list in Reaper. I simply dragged and dropped the .component file into my Macintosh HD/Library/Audio/Plug-Ins/Components folder with all of my other instruments and effect (which DO show up in Reaper). I'm a little confused as to why this instrument isn't available. I tried removing it, opening Reaper; closing Reaper, putting the component file back in plug-ins folder and reopening Reaper to get it to rescan instruments, but nothing shows up. Any ideas why this is happening or any other solutions? Thanks!



Sorry if this is a double post, tried earlier, but I didn't see it posted.
