Apple issues third OS X 10.10.5 beta to developers with minor changes

The new code is listed as build 14F25a, and can be fetched via the Updates tab at the Mac App Store, or through Apple's Developer Center portal on the Web. Notes so far don't hint at any critical changes.

The last beta was released less than a week ago, while the first was issued on July 16.

OS X 10.10.5 is just expected to take care of maintenance for Yosemite, fixing up any large outstanding bugs in the operating system while the company gears up for this fall's launch of OS X El Capitan.

One of these, however, is a recently discovered privilege escalation vulnerability. The flaw can allow malware to grant itself root access, at least one example of which is already out on the Internet.
