Thanks for the great answer, JMB.
While I don’t think of myself as a gamer, I do play Chess most every day. So in retrospect, indeed I’ll be adding that.
Talking books have always been a favorite of mine, so again my thanks for calling that to mind.
BTW, are maintenance utilities and system enhancements such as those found in DiskWarrior, TTP, MacPilot, TinkerTool System, and the like suggested?
