I think this is the message I remember, but probably encountered it during a different search since it cannot be called recent. Peter Dalgaard suggests temporarily setting your version to 10.9.



Despite being a Mac user of long standing, I had no idea how one would do that, but thought a google-search would help:


Perhaps the SPSS administration should distribute free copies of their software to all of the R-Core, since they seem to expect that R-help should be the unpaid support staff for a commercial product.
