Tip: When upgrading PGP Desktop on a Mac OS X 10.6 system, you are prompted to allow various PGP components (such as the PGP Engine) to access information in your keychain. This prompt can appear several times as there are several components that require access to the keychain. To avoid seeing this prompt more than once, be sure to select Always Allow.
Caution: Installing any version of PGP Universal Satellite on top of PGP Desktop 10.x for Mac OS X is an unsupported configuration. Neither program will work correctly. Uninstall both programs and then reinstall only PGP Desktop.
