 +==== Mac OS X and applications (Safari and Mail.app) ====
 +
 +To add the CAcert Root Certificate to Apple Safari, use the Keychain Access application which is shipped with Mac OS X.
 +
 +To install the certificate system-wide, you need to follow these steps:
 +
 +   - Download the [[http://certs.ipsca.com/store/ipsCAGlobal.crt|updated certificate]] and save it someplace convenient.
 +   - Double click on the ''ipsCAGlobal.crt'' file. The Keychain Access application will be launched
 +   - Select ''System'' from the ''Keychain'' dropdownlist and press ''OK''.
 +   - You will be asked to authenticate yourself.
 +   - Click ''Always Trust''
 +   - You will then have to authenticate yourself again.
 +
 +==== Google Chrome ====
 +
 +Google Chrome uses the native operating system to handle certificates.  Follow the instructions to make sure that [[:computing:certificate#microsoft_products_internet_explorer_outlook_etc|Microsoft Windows]] or [[:computing:certificate#mac_os_x_and_applications_safari_and_mail.app|Mac OS X]] has the new certificate.  However, in the version of Google Chrome release version available as of this writing (3.0.195.38) there is a bug which requires clearing the cache to properly validate the new certificate if the website was visited while the old certificate was in place.
 +
 +If you visit the [[https://ibg.colorado.edu|IBG secure website]] and there are no errors or warnings, then nothing else needs to be done.
 +
 +If after updating your operating system the Chrome address bar shows a red ''https:'' with a line through it, then follow these steps to force Chrome to reload the certificate.
 +  - Click the wrench in the top right corner
 +  - Click ''Clear browser data''
 +  - Make sure **only** ''Empty the cache'' is selected
 +  - Change the ''Clear data from this period:'' to ''Everything''
 +  - Click ''Clear browsing data''
 +  - Click the wrench again
 +  - Select ''Options''
 +  - Select the ''Under the hood'' tab
 +  - Scroll to the bottom and un-check the ''Check for server certificate revocation'' box
 +  - Click ''Close''
 +  - Exit Chrome
 +  - Launch Chrome
 +  - Click the wrench again
 +  - Select ''Options''
 +  - Select the ''Under the hood'' tab
 +  - Scroll to the bottom and re-check the ''Check for server certificate revocation'' box
 +  - Click ''Close''
