How to Delete a Certificate on a Mac
Every time a computer connects to a secure website or wireless network, the connection is validated by a virtual security certificate. Information about these certificates is then stored on the computer's hard drive, in case the user again visits the same website or connects to the same network. For Mac users, virtual certificate data is stored in the "Keychain Access" utility program. This article explains how to delete a certificate from a Mac computer, in case you no longer want the secure information stored on your hard drive.
Things You'll Need
- Mac running OS X 10.4 or later
Log on to your computer with an administrative account.
Navigate to the "Utilities" folder in the "Applications" section of the Mac hard drive.
Double-click on the "Keychain Access" icon to open the certificate application.
Select "Certificates" from the list of categories in the lower left corner of the window.
Click on the virtual certificate you wish to delete.
Go to "Edit" in the top menu bar and select "Delete." Click "Delete" to confirm the decision.
