Is it safe to buy Leopard the week it comes out? Are there usually bugs in the OS at the time of the release and one should wait a until the next decimal update before buying? For example is Leopard is released as 10.5.0 should one wait until 10.5.1 before buying it or is it safe to but when it is released? How has this played out in the past with Tiger, Panther, etc.? Thanks.
