YosemiteInstallerIconXAfter installing OS X 10.10.3, you will find your Mac undergo the standard restart that is part of the update process, but then see it hang up as OS X loads, leaving you with a gray screen.

Fix your Mac stuck on encrypting with FileVault

SecurityIconXApple’s FileVault disk encryption option in OS X is a security feature that is highly recommended, especially for portable systems that can be easily stolen. The feature is easy to set up in the Security system preferences, after which the system should take up to a few hours to encrypt the drive, depending on the size and type of drive being used. This should be relatively straightforward; however, in some cases the encryption may get stuck and show a progress bar that will not advance, even after days of waiting. Continue reading

How to secure individual private files in OS X

SecurityIconXYour account in OS X should be relatively secure, and provided you store your files within the structure of your account (ie, the Documents, Music, Movies, and Photos folders in your home directory), then other users on your system will not be able to access your documents.

ActivityMonitorIconXYou may have heard that in order to keep your Mac running in tip top shape, you need to perform regular maintenance routines on it to clear out caches and other temporary items.
