If this has already been covered, I apologize for the redundancy. I was playing with the problem with a Mac and PC side by side. The first test was to limit the iterations to see if the algorithm was working at all by running the following on the Mac.
This was the same on the PC. So it appeared the algorithm worked if I killed at iteration X. I started playing with the verification that is used to determine whether to re-apply the function.
FixedPoint[Cos,1.1,SameTest-> (#1 == #2&)]
My conclusion is SameQ has some issue. Anyone think this is correct? BTW, all work on the PC.
