Metal only works on GPUs. That said, there is a function named MTLCopyAllDevices() that returns all the GPUs your system has. Here is a quick example on how I run this in a OS X playground to see what compatible devices my system has.

enter image description here

EDIT:

In Objective-C this would look similar. Just import <Metal/Metal.h> first:

@implementation AppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {

    NSArray *devices = MTLCopyAllDevices();
    for (id device in devices) {
        NSLog(@"%@", [device name]);
    }
}

@end
