how to delete remote control access to IMac

Hello, benniesue.

Thank you for visiting Apple Support Communities.

I would need clarification on this issue as I am not sure if you are attempting to remove Apple Remote Desktop or disable the infrared receiver on your iMac. However, I have included the information on both solutions in the articles below.

Uninstall or disable Apple Remote Desktop

OS X Mavericks: Turn infrared reception on or off

Cheers,

Is there a reason you think it's on? it's off by default.

Apple's built-in tool is easy to turn off.

1. click on apple menu (apple in top left corner)
2. choose system prefrences
3. click sharing
4. un check screen sharing, dvd sharing, remote login, remote management, remote apple events.
