How can I restrict Apple Genius access?

[Apple!Fre@k]

Problem: My Mac goes in to have a part replaced at the Genius Bar tomorrow and I have sensitive files on my computer for work that I can't allow anyone to look at. The tricky part is, Apple needs a log-in account on my Mac with Administrator access so they can run diagnostics. Problem is, even if I restrict the account I created called "Apple" to not be able to open certain files, since the log-in account "Apple" is an administrator account, all they have to do is click "Get Info" on the folder, click the padlock, and change the settings I put in place.

Is there any way to restrict access of another administrator account on my Mac? If so, how do you do it? I want to be able to essentially allow the administrator account "Apple" no access to my user files in my home folder.

Anyone know how this is done?

I'm not sure about a whole account, but you can create an encrypted disk image with Disk Utility and then place the files in there.

It would be impossible to get into the disk image without the password you pick for it, so make sure you don't forget the password as you won't be able to get the files back.

You can't just quickly load these important documents onto a pendrive for a night?

Encrypted drive then.

As stated above, Applications > Utilities > Disk Utility.

Create a new drive image with encryption, choose your password. Done.

If you do go the route of the encrypted dmg, make sure you have a copy of your files somewhere else too. It's not unknown for dmgs to become corrupt and unusable.
