Spy Software

It's very unlikely they installed anything other than Office. You can check your /Applications folder for any new apps. You can also check the following locations for things that launch when you startup:

• System Preferences > Accounts > yourusername > Login Items
  (Lion and ML users: System Preferences > Users & Groups > yourusername > Login Items)
  
  
• /Library/LaunchAgents/
  (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)
  
  
• ~/Library/LaunchAgents/
  (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)
  
  
• /Library/StartupItems/
  (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)

You can also check the Console.app for any logs that may indicate something being installed.

Really, though, all that is unnecessary, as a school or business isn't likely to risk a lawsuit for invasion of privacy.

 

It's the feds, they're tracking your every move

 

Better wrap your computer in tinfoil...

 

I assume you already had LogMeIn and TeamViewer installed, right?

 

If not.... wow. They are tracking him!

 

Worst would be a trojan... You have to checksum all your apps...

Try Bitdefender or MacScan...

 

That's not necessary, as the school isn't going to install malware.

 

I won't trust them. They could perfectly install a RootKit. He probably gave them the root password...

I would also install LittleSnitch and monitor incoming and outgoing connections...

 

Why not just change your password on your user account?

And delete any other accounts that are there?

And is that laptop really yours, or the school's? Some employers do install software (like Team Viewer or LogMeIn) for remote control so that they can provide tech support, install updates, etc. Less likely on a laptop, and super unlikely if YOU own it.

 

Your school IT cannot legally install other software on your computer without your permission unless they expect a lot of lawsuits and fines.

 

You don't need Little Snitch or anything else. You're fine.

 

Have you got some bad history with your school? Or are you just paranoid? I think you are maybe a bit worried someone at your school will see what you do on your laptop!

 

As already stated, a school isn't going to risk the legal problems they would have if they did something that foolish.

 

Yeah, that's not going to happen.

 

I doubt you will find any thing but, if you're worried, install ClamXav from the Mac App Store. Then, run a scan.

Also, run a search using Finder for "/System/Library/Extensions/logKext.kext".

logKext is a fairly well known open source keylogger for Mac that includes remote access capability.

It requires password authentication by an admin to install but it sounds like the IT staff were given that level of access to the system.

If doing these tasks doesn't find anything, then you have peace of mind.
