A new build of the latest beta for the forthcoming OS X Yosemite 10.10.3 was issued on Monday specifically for the few present -- and all future -- owners of the latest 13-inch MacBook Pro. Following the release of the beta
last Thursday, which included a warning of a known issue that meant testers should not install it on the new 13-inch MBP, the new build removes that warning -- suggesting that the issue may be fixed.
The previous build of the third OS X 10.10.3 was numbered as 14D98g, while the new patched version issued on Monday is build 14D105g -- and is available for both developers and AppleSeed registered public testers. Ironically, the major change in the third beta was the introduction of software to control the new
Force Touch trackpad -- found only (at the moment) on the 13-inch MacBook Pro. The issue that is now corrected was causing the new machines not to wake from sleep, or crash on waking.
The new build is also cleared to be installed on the new updated MacBook Air models, which do not have the Force Touch trackpad but carry other improvements, such as the new Broadwell energy-efficient processor that adds to the machines' battery life. In addition, the 13-inch version of the MBA features the new double-speed PCIe SSD storage inherited from the new MacBook.
Apple executive Phil Schiller detailed the revamped trackpad during the company's "Spring Forward" event on Monday. The new design replaces the traditional "diving board" hinge-style trackpad with multi-axis pressure pad that not only offers pressure sensitivity and a second-stage "force click" that is differentiated from a traditional click, it includes a "taptic" feedback engine borrowed from the Apple Watch to give users physical feedback (in the form of momentary vibrations) that an action has been accomplished.
It's unclear if the new build also corrects the other known bugs from the previous 10.10.3. Among the listed known issues were UI elements that didn't appear or function correctly in some cases, and the Photos app included in the beta continued to have some issues. Developers are asked to focus on Wi-Fi captive networks (such as those found in public businesses), screen sharing, and fault-finding in Arabic and Hebrew system languages.
