A long-standing but recently revealed security hole in the EFI boot ROM in OS X system may allow attackers to take over Apple hardware that shipped with a Thunderbolt port.
In the upcoming Chaos Communications Congress in Germany, the attack, which was found by researcher Trammell Hudson, will allow a compromised Thunderbolt device to modify the ROM of a vulnerable Mac, which then could compromise the ROM Continue reading
One of the newer features in OS X Yosemite is the ability to make and take phone calls from your iPhone, which can come in handy if you are working at your Mac and cannot fish through your pockets or bag for your phone. This is especially useful if you use Apple’s earbuds with your Mac, where its volume and mute controls can be used with your Mac, just as they can with iOS devices. Continue reading
If you have an external drive that you use with your Mac, and provided it is in a format that your Mac can read, then you by default should be able to access all of the files on it. However, there may be times when you are either barred from opening or accessing files or folders, or performing actions like deleting files may result in errors.
These error can include simple confirmation requests such as “Are you sure you want to delete the item“, or be full Continue reading
When you start up your Mac, OS X will display a progress indicator on a background with an Apple symbol, right before loading the OS X interface. In versions of OS X prior to Yosemite this was a spinning wheel, and in Yosemite it is an iOS-like progress bar. This indicator should only display for a few moments before you see your login screen; however, if something goes wrong during startup then you might see your Mac pause either for a long time or indefinitely at this loading point.

Apple’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
Being your Mac’s default e-mail reader, Mail is likely the program you use to read messages on your various internet accounts (Google, Yahoo, iCloud, among other). However, for some who use Mail, after upgrading OS X you might find a problem where the text cursor behaves sporadically, and will move backward a few characters every now and then as you enter text, interrupting your ability to type continuously. In addition, you might see garbled output, either as you type or as you read messages sent to you. Continue reading
The Spotlight index in OS X is the database used for quickly accessing file information on your Mac. While this is primarily used for finding files on your system, there are several other services that use Spotlight’s information, and if there is any damage to Spotlight then you might see odd problems and behaviors dotted throughout your system.
