SessionGuard
Stay-awake for macOS
Keep your Mac session awake.
A discreet menu bar utility that simulates tiny mouse micro-movements when you are idle — so a screen share, a long meeting, or a waiting job does not lose the login session to sleep or lock.
Guard starts Inactive at every launch. You turn it on for this session — until you stop it, or until a timed session ends.

Features
Glanceable, tunable, honest
Everything you need to keep a login session alive — without becoming a bulky stay-awake suite.
True user activity
Mouse movement and keyboard key-down reset idle. Micro-movements do not count as activity, so the pointer does not twitch on camera while you type.
Timed sessions
Start Until Turned Off, or 15m / 30m / 1h / 2h / 4h / 8h. When time hits zero, Guard becomes Inactive.
Idle and jiggle settings
Choose Idle Threshold (15s–2m) and Jiggle Interval. Settings persist. Guard itself does not turn back on after launch.
Accessibility onboarding
The first Session explains why Accessibility is required and opens System Settings. No silent first twitch.
Privacy-friendly
No accounts, no tracking. The app works locally. This site is static.
How it works
How it works
Idle, then a 1-pixel move and return. That is enough for macOS to treat you as present.
- 01
Start a Session
Open the menu bar extra. Choose Until Turned Off or a timed duration.
- 02
Stay idle — or keep working
Typing or moving the mouse resets idle. After the Idle Threshold with no User Activity, a Micro-movement may run.
- 03
Micro-movement
The pointer moves 1 pixel and returns. Then SessionGuard waits the Jiggle Interval and checks idle again.

Frequently asked questions
Why does SessionGuard request Accessibility?
macOS requires Accessibility to synthesize pointer events and to observe keyboard activity without recording keys. Without it, Guard cannot Micro-move.
Is my data collected or sent anywhere?
No. This site is static. The app has no accounts and does not send activity data.
Does it keep a Mac awake with the lid closed?
No. SessionGuard keeps a login session alive while the Mac is in use with the lid open. It is not a closed-lid server stay-awake tool.
Does Guard turn itself back on after login?
No. Launch always starts Inactive, even if Start at Login is on. You start a Session when you need it.
Will typing trigger a Micro-movement?
No. Keyboard key-down is User Activity and resets idle. Micro-movements themselves are ignored so they do not retrigger idle.
How do I update?
Download the latest DMG from this site and replace SessionGuard in Applications.
