One of the parameters that we often overlook in our equipment is knowing the version of the operating system used, although we can know the edition not always the version which adds some functionalities of both security and performance in each update..
In the case of the macOS operating systems we know that we find editions such as Sierra, High Sierra or Mojave, but each of them has specific versions that have been released during their period of use, knowing the exact version of our system is useful for tasks as:
- Download drivers or specific applications
- Audit management and many more actions.
