Symantec has released a notification stating users that utilize a MacBook Air (Model 5,2) or a MacBook Pro (Model 10,1) should not enable the PGP Whole Disk Encryption (WDE) feature. Enabling the feature will create problems at boot-time that will render the MacBook un-bootable.
Due to past issues when upgrading OS X, Symantec is advising that users currently encrypted with PGP Whole Disk Encryption or SEE Full Disk Encryption for Macs should NOT upgrade to OS X 10.8 when made available by Apple.
Symantec will release more information once it is available.
If you have any questions, please contact the IT Service Center at firstname.lastname@example.org or call 303-735-4357 (5-HELP from a campus phone. Phone help is available Monday through Friday, 8 am to 7 pm.
