Lock Screen Command for Mac OS X

更新：在 High Sierra 可以用熱鍵 Control + ⌘ + Q 來鎖住螢幕。

下面的指令在 Mac OS X High Sierra 已經無效了，因為 Keychain Access 在 menu 的選單已經沒有 Lock Screen 選項了。

我想要有一個簡短的指令可以鎖住 Mac 螢幕，找到了一個好方法：


#import <objc/runtime.h>
#import <Foundation/Foundation.h>

int main () {
    NSBundle *bundle = [NSBundle bundleWithPath:@"/Applications/Utilities/Keychain Access.app/Contents/Resources/Keychain.menu"];

    Class principalClass = [bundle principalClass];

    id instance = [[principalClass alloc] init];

    [instance performSelector:@selector(_lockScreenMenuHit:) withObject:nil];

    return 0;
}

#import <objc/runtime.h>

#import <Foundation/Foundation.h>

int main () {

NSBundle *bundle = [NSBundle bundleWithPath:@"/Applications/Utilities/Keychain Access.app/Contents/Resources/Keychain.menu"];

Class principalClass = [bundle principalClass];

id instance = [[principalClass alloc] init];

[instance performSelector:@selector(_lockScreenMenuHit:) withObject:nil];

return 0;

}

存檔取名為 main.m 然後編譯

clang -framework Foundation main.m -o lockscreen

這樣就有一個可以執行的 lockscreen 了。
