Re: A serious error?
Thanks a lot Peter. Yours was the suggestion that set me on the right track! I repaired permissions on my hard disk and Mathematica 5.1 launched with problems. Indeed, it was after all font related, as I had suspected. Among the permissions that were wrong most were in ./Library/Fonts. In fact I used to know that incorrect permissions could cause such problems and I frequently used this method in earlier versions of Mac OS X, but I have never suffered from anything in Tiger (Mac OS X 10.4) so I assumed it somehow dealt with this sort of thing by itself. Of course Mathematica reporting "error 16" did not help. If it told me that it could not access something I would have understood the situation at once. Finally, I would like than everyone else who wrote to me to try to help. They all made good suggestions, but it required someone who had had a very similar experience to make the right one. Curious that that person turned out to be a Windows user ;-) Thanks again Peter. Now I can again remove Mathematica 5.0 and use some of my favorite new functions, like Tuples ;) On down side, I have now lost some basis for the argument I have been making to my wife, that I need a new MacBook Pro ;-) Andrzej On 3 Dec 2006, at 00:13, Peter Pein wrote: > Hello Andrzej, > > I've got the same symptoms a few days ago on my Windows 2000 PC. > The system > did not go down properly, so I pressed the reset button after some ten > minutes.
