Everything suggests that those from Cupertino have their machinery at full throttle so that this new version of the Mac system reach end users as soon as possible.
This new version of macOS Sierra 10.12.3 comes encrypted with the number 16D30a, something strange since the third beta had an encoding such that 16C48b. It is already available in the Apple developer portal to be downloaded and installed, which is surely being done right now by thousands of people.
Regarding the purpose of this latest version of macOS Sierre, we have already told you previously that it would come to solve existing problems in the current version, improve performance problems that have been identified in previous betas and in this way have a much more stable system.
