I have a new MacBook and am very pleased with it. It is currently running 10.4.7. Jon pointed out that the latest Tiger is 10.4.9 and, while I'm happy to update software generally, I have been concerned about some threads I've seen regarding problems with updates and wireless dropouts etc. There is a part of me that thinks, as all is working, leave it alone (at least until this 'issue', if indeed it is one, is fixed with a later release). Is there such a problem with the latest Tiger or indeed are there any others?
