Question

I want to enable access for assistive devices programatically on 10.9. On 10.8 and lower I was using following Applescript to enable access for assistive devices:

Answer 1

I have found the following code snippet which properly requests Accessibility permissions in OS X 10.9:

if (AXIsProcessTrustedWithOptions != NULL) {
    // 10.9 and later
    const void * keys[] = { kAXTrustedCheckOptionPrompt };
    const void * values[] = { kCFBooleanTrue };

    CFDictionaryRef options = CFDictionaryCreate(
            kCFAllocatorDefault,
            keys,
            values,
            sizeof(keys) / sizeof(*keys),
            &kCFCopyStringDictionaryKeyCallBacks,
            &kCFTypeDictionaryValueCallBacks);

    return AXIsProcessTrustedWithOptions(options);
}

// OS X 10.8 and older
