Get OSX version with objective-c

How would I be able to get the OSX version in objective-c? I would like to avoid using shell commands. E.g "10.5" or "10.4"

As of 10.10 you can use NSProcessInfo.processInfo.operatingSystemVersion to get a NSOperatingSystemVersion struct.

typedef struct {
    NSInteger majorVersion;
    NSInteger minorVersion;
    NSInteger patchVersion;
} NSOperatingSystemVersion;

There's also a helpful isOperatingSystemAtLeastVersion: method. 

NSOperatingSystemVersion minimumSupportedOSVersion = { .majorVersion = 10, .minorVersion = 12, .patchVersion = 0 };
BOOL isSupported = [NSProcessInfo.processInfo isOperatingSystemAtLeastVersion:minimumSupportedOSVersion];

add this code after #import

#define SYSTEM_VERSION_EQUAL_TO(v)                  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)

after adding above code please add below code where you want to see your os-version

NSString *systemVersion = [[UIDevice currentDevice] systemVersion];
        NSLog(@"System version :%@",systemVersion);

you can easily get OS-version by above code

Thank you

NSProcessInfo *pInfo = [NSProcessInfo processInfo];
NSString *version = [pInfo operatingSystemVersionString];

Sorry for the formatting, I'm using my iPad to answer this.

See this response using NSAppKitVersionNumber in case you're using AppKit in your app as well (and want to run on 10.8+ as Gestalt is now deprecated):

How to know what Mac OS the app is running on?

You can parse it in this way to get the format you want:

NSProcessInfo *pinfo = [NSProcessInfo processInfo];

NSArray *myarr = [[pinfo operatingSystemVersionString] componentsSeparatedByString:@" "];
NSString *version = [@"Mac OS X " stringByAppendingString:[myarr objectAtIndex:1]];

This f.e. will give you Mac OS X 10.6.8

You can use the Gestalt function to access the components of the OS version.

Old-time users of Gestalt may be amazed to find that it is still available in 64-bit.
