Alright, just received my copy of Leopard off amazon today and promptly did an archive & install with no hitches whatsoever. Only thing I had to do was manually go enable the setup assistant after installing so I could watch the intro movie (disabled it afterward). Anywho, out of nowhere, after I logged into Leopard, I find the following sitting in my root drive: Being slightly worried now, since 'basesystem.pkg' is exactly that, the base system package, I opened it to find two files, 'ACL.plan' and 'AdditionalEssentials.plan'. Plus the folder is read-only so I can't remove it temporarily to see if it breaks anything.. Anyone got any clues?
