It was only a week ago when Apple started shipping the early builds of Mac OS X 10.5.5. However, in the ever-changing world of OS updates, MacNN reports that Apple has prepared another developer seed of 10.5.5 for beta testing.
The latest build number is 9F9 (the last one being 9F5). According to the article, Apple has reportedly squashed over 100 bugs in Leopard. Unlike the last build, MacNN says that this build is safe for Macs with integrated graphics cards.
Christina Warren notes that this is only the 9th build of 10.5.5 and that Apple normally ships around 20 OS update builds before considering "gold master."
