Remote Mouse & Keyboard can send a Wake-on-LAN packet to a Mac that was saved while awake. Wake-on-LAN is a request to the network hardware, so success depends on more than the iPhone app.
Quick Answer
Yes, an iPhone can wake a compatible Mac with Wake-on-LAN. Pair and save the Mac first, enable the macOS setting for network wake when available, keep the Mac connected to a network that permits wake traffic, and use the Wake action for the saved device. Waking from sleep over Ethernet is generally the most reliable setup.
Before You Test
- Connect to the Mac in the app while it is awake.
- Make sure Remote Helper is current and the Mac remains saved in the app.
- In macOS settings, enable the available option for wake or network access.
- Prefer a wired Ethernet connection when possible.
- Put the Mac to sleep, wait briefly, then send the Wake action.
- Allow time for the Mac and helper to reconnect after waking.
What Determines Whether It Works
| Factor | Why it matters |
|---|---|
| Mac model and firmware | The hardware decides which low-power states can listen for wake traffic |
| Sleep versus shutdown | Sleep is generally more wake-friendly than a full shutdown |
| Ethernet versus Wi-Fi | Ethernet is usually the more predictable Wake-on-LAN interface |
| macOS power settings | Network wake must be allowed where the option exists |
| Router and network | Guest isolation, VLANs, and blocked broadcast traffic can stop the packet |
| Saved device information | The app needs the correct network identity for the Mac |
What Wake-on-LAN Does Not Guarantee
It does not bypass power loss, a disabled network adapter, a router that blocks local broadcasts, or unsupported Mac power states. It also does not provide remote internet access by itself. The normal app connection still requires the Mac and iPhone to be reachable and Remote Helper to start after macOS wakes.
Troubleshooting
- Test from sleep before testing deeper power states.
- Test Ethernet if Wi-Fi wake is inconsistent.
- Confirm the iPhone and Mac are on the same trusted network.
- Avoid hotel, guest, or corporate networks with device isolation.
- Wake the Mac manually once, reconnect, and save it again if network hardware changed.
- Check the Mac helper discovery guide if it wakes but never reconnects.
Wake Mac FAQ
Can I wake a Mac mini connected to a TV?
Yes, if that Mac mini and network support the required wake state. A wired Mac mini is a particularly practical setup to test.
Does the helper receive the wake packet?
No. The network interface and Mac firmware receive the wake request while the computer sleeps. Remote Helper becomes available after macOS wakes.
Can I wake the Mac from outside my home?
This app is designed for local-network control. Do not expose helper ports or weaken router security to make Wake-on-LAN reachable from the internet.
