Illustrator 22.1 doesn't store version information in the metadata
In previous versions of Illustrator I could view which version of Illustrator a file was saved as, and the version that created it, in 'Get info' in the Mac finder. For example: 'Version: Saved As v.15 Created by v.22.0.1'. This info now isn't saved with the file as shown on the attached screenshots. For us this was a very useful for checking what version a file had been saved for.
CS 6 was the best version of illustrator, then it's not good anymore
