The day after the release of iOS 10.3.2 Public beta 1 for iPhone and iPad, Apple has issued the first public beta of macOS Sierra 10.12.5 designed for participants in the testing program. The version of the app debuted at the beginning of the week.
Update macOS 10.12.5 aimed at correcting previously found errors in the operating system for Mac computers. Apple does not list the changes. But the main reason was for the release of the updates was to fix bugs made in the development of previous versions.
macOS Sierra 10.12.4, recall, was released after eight test releases and unlike previous updates does not offer significant changes in the interface, with the exception of the new regime Night Shift, reducing eye strain to the users by reducing the blue component of light. As a result, the work for the Mac at night becomes more comfortable, but subsequent sleep is more restful and quality.
Great emphasis in macOS Sierra 10.12.4 Apple developers have made on the improvement of the protection mechanisms, and improving the performance, stability and security, as well as on fixing bugs in the previous release.
Install update macOS 10.12.5 beta 1 in an open testing program. The release of the final version of the update is expected in may this year.
