If you leave your Mac unattended and unprotected, you might wonder if someone has used it without your permission. Fortunately, Mac OS X provides an easy way to track system wake-up events and find out if someone has accessed your computer. This guide will show you how to know if someone has used your Mac.
How to Find System Wake-up Events on Mac
The easiest way to identify if someone has used your Mac is by checking the system wake-up events. Follow the steps below:
- Put your Mac to sleep when you’re away.
- Use Spotlight (Command + space bar) to find and open the console.
- Click the search bar in the upper right corner of the console and type “Wake” to sort the system logs for wake events.
- Scroll to the end of the list to find the most recent events, and look for a wake-up note that matches the time you think your Mac was used.
- Read the reasons for the alarm to see how the Mac was awakened and by what method.
If you find a date, time or wake-up event that doesn’t match your own normal Mac use, it’s a sign that someone has used your computer. You should enable password protection on your Mac and lock the screen every time you leave it unattended to ensure sensitive information is not accessed by others.
Using the Command Line to Find Wake-up Events on Mac
If you prefer to use the command line, you can search for wake-up events by using the syslog command with grep:
syslog | grep -i “Wake up cause”
This displays the same wake-up information as the console, but from the command line. It can be more powerful for advanced users because they can run scripts to find all the wake-up events.

This guide is only compatible with Apple devices using the macOS or iOS operating system.
What information can I get from the console or the command line?
You can obtain the wake-up events, including the date, time of activation and the event that caused the computer to wake up.
Can I detect if someone has logged in to my Mac?
Unfortunately, the console and command line do not provide such a record of logon attempts or screen saver wake-up. You should password-protect your Mac and use the screen lock feature if you use a public computer.
What should I do if I found out someone has used my Mac without my permission?
Enable password protection and set your screen saver to start after a few minutes of inactivity. This ensures that only you have access to your computer.
