There are a few signs that could indicate someone by your side on the Internet. These different methods of monitoring will change over time. As computer technology improves, so do the methods used to snoop around online.

Look for a webcam light that’s on when it shouldn’t be

Look for a webcam light that’s on when it shouldn’t be
If your Mac is being monitored, you may see a light that indicates it’s being watched by someone else. This can usually be found on the upper-right corner of the screen, next to where Wi-Fi or Bluetooth is used. If there’s no icon in this area, it means that there aren’t any cameras connected to your Mac (this is normal).

Check whether the hard drive light is constantly on

The hard drive light should be on when the computer is on and the hard drive is running. It should turn off when you shut down your Mac or take it out of sleep mode. If it stays lit, then there’s a chance that someone has infected your machine with malware and is using it to spy on you.
If you see this happening, check for suspicious behaviors in Activity Monitor.

Look for odd behavior from the computer and the operating system

Look for strange behavior from your Mac, as well as any other devices that are connected to it. If you’re not sure how to check this, then ask someone who knows a lot more than you do (like me). It may seem like an obvious thing to do, but many people don’t think about checking their computers’ settings or software updates before they go on vacation or leave home for work—and this could be why they ended up being monitored!

Check what applications are running in Activity Monitor

Activity Monitor is a great way to find out what applications are running on your Mac. It will show you the processes and applications that have been launched, as well as how long they have been running for.
To open Activity Monitor:

• Go to System Preferences > Energy Saver > Processes (or glance at the bottom of the screen).
• Click on “Processes” under Energy Saver in System Preferences > Energy Saver window to bring up this window with all of your open apps listed beneath it

Manually look for suspicious files

• MacOS has built-in tools that can help you identify whether your Mac is being monitored, but they’re not always accurate. To get the most accurate results, we recommend using manual methods like these:
• Open Activity Monitor and check if there are any processes running from the Applications folder in Finder or elsewhere on your drive (this will show up as /Applications). If a process is running from an app other than what you were working on when this happened, it might be indicative of an unauthorized access attempt by someone else accessing your machine. You may also see a green dot next to one of these items indicating that it’s been authorized by Apple; this would indicate that no unauthorized access was attempted (but could still mean someone else had requested something from you).
• Check for new files generated by applications installed on your system since installing one—if they don’t match up with what was installed previously then something fishy could have happened during installation/uninstallation times when no one was around!

If you are concerned about monitoring your Mac, there are steps you can take to figure out if your activity is being monitored, and if so, how to stop it.

If you think that someone is monitoring your computer:

• Check for signs that a third-party app has been installed on your Mac. Third party apps are programs that provide additional functionality for a specific purpose (for example: antivirus software). If one of these apps is installed on the machine where they wouldn’t normally be allowed by default (such as in the background), then it’s likely they’re trying to monitor what happens under the hood of the computer itself. It may also be possible to detect when this happens because some third party programs will let themselves be detected by other things running on the same device as well as other devices connected via Wi-Fi or Bluetooth.* Check whether all sensitive files have been encrypted with OAuth2/OAuth2a/OAuth5 protocols – this prevents them from being read unless given access through authentication credentials such as Facebook Connect

If you think your Mac may be under surveillance, there are a few steps you can take to figure out if this is true. Our best advice? Talk to a computer technician or an Apple expert in person. They’ll be able to run different diagnostic tests on your machine and look for any telltale signs of malware or hidden monitoring software. So if you have the slightest suspicion that your Mac might have been compromised, don’t hesitate to schedule an appointment with the 403it
