I and my wife both use Macbook Pros. Hers is "old" (2018), mine is "new" (2023). On Sunday Jan 7 2024 I updated Mac OS on her "old" laptop. The update summary said, "This request came from Firefox on Mac OS X 10.15." (see screenshot) and recommended security changes. We were not using Mac OS X before the update. The "old" laptop is working normally as far as I see. I am writing this request from the "new" laptop. What's going on? Is the "old" laptop compromised? If so, what do I need to do? Thanks!

On Mac, the user agent is currently locked to Mac OS X 10.15 and newer macOS 11-13 versions all show as Mac OS X 10.15, so nothing to worry about.

  • Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:121.0) Gecko/20100101 Firefox/121.0
