I have just installed Snow Leopard ... see system details below.

1	The 1st indication of potential problems was that double clicked  
Mathematica notebooks were opened by Apple Numbers by default.

	That was reset by opening a notebook with Mathematica and resetting  
the application association.

2	The 1st open notebook generated the error:

	"Assertion '(Unknown OS Error)' failed at LikeResource.c:56"

	However continuing did start Mathematica and run some initial notebooks OK

3	However there is also a problem with Mathematica Documentation Display. For  

	Needs["Benchmarking`"]  displays as NeedsC"Benchmarking`"G


	BenchmarkReport[] displays as BenchmarkReport@D

In spite of that the BenchMark Report runs to completion and displays  
OK! and also gives the improvement below:

Excellent speed improvement

  {"Benchmark Result:", "1.92"}

I expect that I will run across more problems and will be working with  
WRI & Apple to resolve my issues.

I wanted to alert MathGroup members ASAP so they may choose to hold on  
conversion to Snow Leopard
until the problems are better understood or fixes become available.

Best wishes ... Syd
