Macsus Support
Macsus shows your MacBook on your iPhone, live: a 3D model with the real lid angle and whatever is plugged in, then battery, power, temperatures, fans, processes, ports, display, audio and sleep, with controls like volume, brightness and lock. Two apps work together: Macsus for Mac, which lives in the menu bar, and Macsus for iPhone.
What you need
- A Mac with Apple silicon, on macOS 15 or later. Some readings depend on the model and macOS version: the live lid angle needs a MacBook whose lid sensor macOS exposes, and the tilt needs macOS 27 and an M2 or newer.
- An iPhone on iOS 26 or later.
Getting started
- Open Macsus on your Mac. It sits in the menu bar as a small laptop.
- Click it and choose Pair iPhone. A code appears.
- Open Macsus on your iPhone, tap Pair with your Mac and scan the code.
- Both screens show the same number. If they match, choose Allow on the Mac.
Only iPhones you allow on the Mac can connect, and the menu bar icon changes to a Mac with an iPhone whenever one is watching.
Common questions
My iPhone can't find my Mac
- Check that Macsus is running on the Mac (the laptop in the menu bar) and that the Mac is awake.
- Keep both on the same Wi-Fi, or close together: they can also talk over Apple's peer-to-peer Wi-Fi.
- On the iPhone, allow Local Network for Macsus in Settings > Privacy & Security > Local Network.
Seeing my Mac away from home
Away from your Mac, Macsus passes encrypted messages through your own iCloud. Both devices need to be signed in to the same Apple Account with iCloud turned on, and the Mac needs to be awake. It's slower than nearby: changes take a few seconds rather than being instant. If something is missing, the iPhone app's Settings says what, under Away from home. You can switch it off on the Mac with Status through iCloud in its menu.
When my Mac is asleep
A sleeping Mac runs no apps, Macsus included. Your iPhone shows the Mac as it was when it went to sleep, and live readings come back when it wakes.
That's why Sleep on the iPhone asks first and offers two ways to keep a way back in:
- Lock and Turn Off Display: the Mac looks asleep but stays awake and reachable, until its own sleep settings put it to sleep.
- Sleep, then wake in 30 minutes to 8 hours: the Mac wakes by itself at that time and your iPhone reconnects. macOS lets only an administrator schedule a wake, so this needs Admin features on the Mac. It works best with the lid open; with it closed, macOS may put the Mac straight back to sleep.
Some readings or controls are missing
- Wi-Fi network names need Location access for Macsus on the Mac: macOS shows network names only to apps that have it. Macsus never asks where you are.
- Changing Energy Mode needs the optional helper: turn on Admin features in the Mac menu and approve it in System Settings.
- Some sensors exist only on some Macs. Macsus shows what your Mac has.
Updates
Macsus for Mac updates itself. It checks once a day, and installs a new version when no iPhone is watching, so nobody gets cut off. When an update is waiting, your iPhone's Settings offers to install it right away. Macsus for iPhone updates through the App Store.
Removing an iPhone or a Mac
On the iPhone, open Settings, swipe the Mac and choose Forget; if the Mac can be reached, the iPhone is removed there too. On the Mac, click Remove next to the iPhone in the menu. Once the Mac has removed it, that iPhone's data in iCloud is deleted.
If Macsus quits unexpectedly
While Open at login is on, Macsus for Mac reopens by itself. To help us fix it, choose More > Report a Problem in its menu. That saves a folder on your Mac with the crash reports and a log, without your Mac's identifiers; email it to us if you like. Nothing is sent automatically.
Uninstalling Macsus from your Mac
In the Macsus menu, turn off Open at login and Admin features, choose Quit Macsus, then move Macsus from Applications to the Trash.
