Apple patches 56 vulnerabilities in OS X El Capitan, improves Live Photo sharing
Apple yesterday updated OS X El Capitan, patching a slew of security vulnerabilities, fixing other non-security bugs, and adding capabilities to some first-party apps.
The Cupertino, Calif. company also issued less sweeping updates — composed only of vulnerability fixes — to OS X Yosemite and OS X Mavericks, the 2014 and 2013 editions, respectively.
OS X 10.11.4, the fourth update to El Capitan since its September debut, addressed 56 vulnerabilities. Twenty-three applied to OS X Yosemite and 22 to Mavericks.
Apple stopped patching Mavericks’ predecessor, 2012’s OS X Mountain Lion last year, as part of its practice to support only the OS X editions designated as “n,” “n-1” and “n-2,” where “n” is the newest. Under that scheme, El Capitan is “n,” Yosemite is “n-1” and Mavericks is “n-2.” As “n-3,” Mountain Lion has been retired.
