试试这个终端命令:

ioreg -rd1 -c IOPlatformExpertDevice | awk '/IOPlatformUUID/ { split($0, line, """); printf("%s
", line[4]); }'

来自这里

这是用 Cocoa 包装的命令(可能会更简洁一些):

Here is that command wrapped in Cocoa (which could probably be made a bit cleaner):

NSArray * args = [NSArray arrayWithObjects:@"-rd1", @"-c", @"IOPlatformExpertDevice", @"|", @"grep", @"model", nil];
NSTask * task = [NSTask new];
[task setLaunchPath:@"/usr/sbin/ioreg"];
[task setArguments:args];

NSPipe * pipe = [NSPipe new];
[task setStandardOutput:pipe];
[task launch];

NSArray * args2 = [NSArray arrayWithObjects:@"/IOPlatformUUID/ { split($0, line, "\""); printf("%s\n", line[4]); }", nil];
NSTask * task2 = [NSTask new];
[task2 setLaunchPath:@"/usr/bin/awk"];
[task2 setArguments:args2];

NSPipe * pipe2 = [NSPipe new];
[task2 setStandardInput:pipe];
[task2 setStandardOutput:pipe2];
NSFileHandle * fileHandle2 = [pipe2 fileHandleForReading];
[task2 launch];

NSData * data = [fileHandle2 readDataToEndOfFile];
NSString * uuid = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
