Console error showing up in Retro 12.5 (retropds.25)

[henry-in-florida]

I'm noticing an error in retro whenever the system starts up: 

 

11/21/15 19:28:18.385 retropds.25[744]: WARNING: The Gestalt selector gestaltSystemVersion is returning 10.9.2 instead of 10.11.2. This is not a bug in Gestalt -- it is a documented limitation. Use NSProcessInfo's operatingSystemVersion property to get correct system version number.

I asked about this one once and they said it's a known issue, but not to worry about it.
