#define keyy(key_) CFEqual(key, CFSTR(key_))

Works on Checkra1n but not Unc0ver - crashes into Safemode (iOS 13.3)

%hookf(Boolean, "_MGGetBoolAnswer", CFStringRef key) {
    if (keyy("nVh/gwNpy7Jv1NOk00CMrw"))
        return YES;
    return %orig;
}

Works on Both

extern "C" Boolean MGGetBoolAnswer(CFStringRef);
%hookf(Boolean, MGGetBoolAnswer, CFStringRef key) {
    if (keyy("nVh/gwNpy7Jv1NOk00CMrw"))
        return YES;
    return %orig;
}
