Re: [B2-devel] SS MacOSX on PPC problem (precise timer patch issue?)

[Ronald P. R. <ron...@xs...>]

Those are the builds I compared. Your 2009-07-26 build does not have  
the problem, your 2009-08-23 build does have the problem.

There are now a couple of different reports from this (or at least a  
very similar) problem on PPC and one on Intel. SheepShaver either  
quits or freezes, always just after the MacOS welcome screen appears  
and before one can see extensions loading. Disabling extensions at  
startup does not help.

On my PowerBook G4 it is a freeze. The PB has a fresh and updated  
Leopard installation with no additional software but the Developer  
Tools.

You have seen the report of this (or a similar) problem an Intel  
machine in Emaculation.com forum.
