macOS Sierra 10.12.3 beta 4 was released by Apple this evening, just two days away from offering macOS Sierra 10.12.3 beta 3 to application developers. The appearance of macOS Sierra 10.12.3 beta 4 after such a short period of time compared to the previous build is unusual and suggests the idea that there were major performance problems in the previous version.
Exactly as in the case of the previous version, in macOS Sierra 10.12.3 beta 4 the Apple company claims to have solved operational and performance problems and improved the general experience. We don't know what this means, because Apple doesn't offer a list of changes in which to provide clear details, so we probably won't find out soon exactly what has changed.
At the moment macOS Sierra 10.12.3 beta 4 can be downloaded by application developers for the macOS platform directly from the Mac AppStore, or the center dedicated to them on the Apple website.
