mac os x security update Mac users who are running OS X Mavericks and OS X Mountain Lion will find an important security update available to them. Labeled as Security Update 2015-004 1.0, the software update includes many fixes to a wide variety of potential security issues for OS X, and is therefore recommended for all Mac users running OS X 10.9.5 or OS X 10.8.5 to install.

Users who are running OS X Yosemite will find the same security fixes bundled within the OS X 10.10.3 software update, thus there is no separate security update patch available for Yosemite.

To get the security update for OS X Mavericks or OS X Mountain Lion, you’ll want to run the Updates mechanism of the App Store, available through the  Apple menu > Software Update. If you don’t find the update immediately available, hit Command+R to refresh the Updates tab of the Mac App Store.

The update download is fairly small but requires restarting the target Mac to complete installation of.

    I suppose OS 10.7 is forgotten about!
    Except for iTunes.

    This was released along with OS X 10.10.3 Yosemite but it did not appear in my software update screen on OS X Mavericks until today. Updated it.

    Until this latest update, I could print PDFs with Preview that sometimes failed with Adobe. But now I get an error message on PDFs I printed via Preview the day before. However, I can now print the PDF in Adobe, where before it would start and then just stop.

    I prefer the ability to print via Preview because I can do it at 600 dpi, which sometimes works better. Now I get a page with an error code on it at 600 or 1200 dpi in Preview.
