    There are no Objective-C classes out of the box for this. Of course you can write your own. Simplest way is to use DiskArbitration framework to get the available drives, grab the BSD name (kDADiskDescriptionMediaBSDNameKey) from the DADiskRef and feed that to opendev().

    Internal/startup drives requires root permission to open though.

    Not really going to find anything simpler, Apple's Objective-C frameworks were never really designed to go that low level, so you are stuck using the C API for most things(and as luck would have it, all valid C code is valid Objective-C code :p)
