model-identifiers's Introduction

model-identifiers

Apple model identifiers. Gives you an approximation of the device based on the model identifier.

Each entry provides the following information (if available):

Device - the device name (eg. MacBook Pro, iPad 2, iPad Air)
Generation - device generation (eg. Late 2006)
Variant - variants within the same generation (eg. 17-inch, Retina)

Find the identifier

To find your Mac model identifier, on the command line try:

$ sysctl -n hw.model

or in code:

#include <sys/types.h>
#include <sys/sysctl.h>

#if TARGET_OS_IPHONE
	char *propertyName = "hw.machine";
#else
	char *propertyName = "hw.model";
#endif

size_t size;

// Mac: use 'hw.model'. On iOS use 'hw.machine'
sysctlbyname(propertyName, NULL, &size, NULL, 0);

char *model = malloc(size);
sysctlbyname(propertyName, model, &size, NULL, 0);

// model identifier as NSString
NSString *modelIdentifier = [NSString stringWithCString:model encoding:NSUTF8StringEncoding];

free(model);

Identifier Uniqueness

Be aware that a single identifier may refer to multiple models from different years or with different characteristics. In this case the Generation and/or the Variant could not be determined exactly and the key may be missing.

Somewhere around 2010 this practice was changed and from that point on most models have their own unique identifier.

Add extra key for ambiguous model identifiers

Be aware that a single identifier may refer to multiple models from different years or with different characteristics. In this case the Generation and/or the Variant could not be determined exactly and the key may be missing.

In these cases, a key 'Variants' could be used, which has an array value, with multiple dictionaries with the 'Generation' + 'Variant' keys.
