Knock and Apple Watch: a match made in heaven. Knock 2.0 makes unlocking your Mac faster and more secure than ever.

You keep your iPhone with you all the time. Now you can use it as a password. You never even have to open the app— just knock on your phone twice, even when it’s in your pocket, and you're in. And if you have an Apple Watch, you can unlock your Mac right from your wrist.

Using Knock won't drain your iPhone's battery, even if you use it all day every day. Knock securely communicates with your Mac using Bluetooth Low Energy, a new technology that draws very little power.

I wish there'd be compatibility with Windows 10 PC's, as well as those PC's running Android.

A note for some people who have trouble with this: first, WOL (aka Wake On LAN), or magic packet has to be enabled in BIOS (if it is on-board)... Or in the driver properties (in windows it will be under power saving tab)— make sure "allow this device to wake the computer".

Second, I am not 100% sure on this but quite sure that to allow wake on LAN, a wired connection is required. It will not work if the computer is using a wireless card/dongle/adapter.

Next, the port needs to be allowed on the computer, in the firewall, the port is port 9 (UDP type). You may want to double check that but that's my recall.

If all those fail, check into S states and see that the proper ones are enabled. S3 is akin to sleep mode, while S5 I believe is totally powered off.

I'm sorry for any incorrect info above, it's been several years since I messed with this stuff, I'm a bit rusty. But I know it's very close.

Please correct me if I'm wrong. Just some helpful tips hopefully.

Also think about packets from things like LogMeIn are coming from the outside (internet/WAN) while this are coming from inside the network (LAN).

Most times these apps use UPnP (dynamic port opening/forwarding) to automatically open the necessary port in the router to allow these ports to accept packets from the WAN side, while internal requests or software may not, since they are routed internally and are not NAT'd.

It's late and my brain is foggy, but basically, the computer when in sleep mode will still listen for network requests like this and wake up, but if they are in deeper (S4?) hibernation mode, it does not.

"Sleep mode" provides just enough power (5v?) to keep the computer on, but at the lowest possible way. Contents in memory are not cleared; the small voltage allows the RAM to keep its contents.

In hibernation mode, the computer essentially saves the entire contents of RAM memory to a physical file (hibernation file) and then shuts off. When it wakes, it reloads the memory contents from file.

Pretty high price for what others offer that can wake your Mack or PC from off, sleep, or screen saver.
Neat idea. I think it would be a waste of your $3.99
Scany, VNC Viewer, Splashtop do this and more. I mean they don't work with a knock. But a hand shake. Lol
A network card on a PC that supports wake on LAN and WiFi. A router that is capable of pushing port 9 to the right ip for external wake on LAN

Does not work if your system goes into power saving mode, I mean when the screensaver is visible or the screen goes black and the login window is not visible.

So pretty useless.
Save your bucks.
