Apple dropped a slew of new beta releases earlier this week for iOS 8, Yosemite and Apple TV, but the company is also patching up Mavericks with the second beta build of OS X Mavericks 10.9.5.
OS X 10.9.5 build 13F12 was seeded to developers this morning, after the company just released the first beta for OS X 10.9.5 a little over a week ago. The release notes don’t mention any features have been added, but there are a number of new bug fixes.
Apple is asking developers to focus on Safari, USB, Graphics, USB Smart Cards, and Thunderbolt issues in Mavericks beta. A new beta for OS X Yosemite was also released earlier this week that included a redesigned calculator, new Safari options, and other tweaks.
