There were two issues with the macOS regexes:
- The regexex accepted only spaces separator. But non-breakable spaces are also used from time to time. Replacing spaces by \s fixed the issue (other product regexes were also updated - never know).
- The first regex, the one that accepted major releases with no minor version, were not useful (covered by the second regex) and partly catched valid versions (such as 13.1), who was then ignored. I removed it.
