How to use FileVault to encrypt a PowerPC Mac or 10.4 Intel Mac (Go back)
Encrypting a 10.4 or 10.5 PowerPC based Mac or a 10.4 Intel Based Mac FileVaultAll laptops that connect to the Partners network, or maintain Partners Confidential Data, must be encrypted. However, there is currently no known product that supports Whole Disk Encryption on PowerPC Based Macs (e.g. Aluminum and Titanium Powerbooks).
FileVault EncryptionThe recommended approach for users of PowerPC based Macs running OS X 10.4 and 10.5 is to use the FileVault software included with the operating system. FileVault will encrypt all information in your home folder so that unauthorized users, applications, or utilities cannot access your data. Please reference the following Apple Support documents on how to configure FileVault.

Known IssuesPasswords and Backups - As FileVault is not a centrally-managed encryption solution, it is extremely critical you remember the passwords that are created when enabling FileVault. If you enable FileVault and then forget both your login password and your master password, you will not be able to log in to your account and your data will be lost forever. Partners will not be able to help you recover your data. Also, Partners strongly recommends backing-up your data before implementing FileVault or any brand of encryption software.
Backup Process - While your home folder is being encrypted, you will not be able to log in to your account or use your computer to do other tasks. The process could take a while, depending on how much information you have in your Home directory.
Time Machine Backups - Under normal operation, Time Machine will backup information in a user's Home directory while the user is logged in. Once FileVault is enabled however, Time Machine will only back up a user's Home directory only after the user logs out. Additionally, not all features of the Time Machine backup facility work when it is used in conjunction with FileVault in Mac OS 10.5. For example, a single file cannot be restored from the archive using the Time Machine interface; only restoring the entire FileVault is possible. Single files can however be restored manually using the Finder.
While FileVault is being enabled, the user's Home directory is copied to a space on the hard drive, and the original is not deleted until the end of the process. This means that prior to enabling FileVault, the free space on the hard drive should be equal to or greater than the size of the current Home directory. This free space requirement is also necessary to disable FileVault. If you do not have this amount of free space available on your laptop, then it may be necessary to offload some of the files in your Home directory to an external drive before beginning the process. You can migrate the files to the encrypted Home directory after FileVault is enabled.
