That could mean a 2010 MBP, that can be updated up to High Sierra with a third party enabler, or more likely Ces VLC meant that the machine's original and default OS from Apple was High Sierra, indicating a 2018 model, which is still supported by Apple up to current, or Ventura. https://en.wikipedia.org/wiki/MacOS_version_history#Releases Anyway, while the names of all the macOS versions are so very cute, they inevitably waste my time because I always have to double check the name against the actual OS version number, which is the detail that matters. Up to Lion, I had them memorized. Since then I have resisted learning them all because Apple aggravatingly increased its OS release cycle and feature creep to yearly. I honestly wish there were two releases, one that included new features, and one that didn't require disabling all the unwanted and unnecessary new features.
