A friend of mine let me know that last night, Apple seeded Mac OS X 10.5.8 Build 9L30 to developers. Apparently, this version had only one item in the change list, that item related to an issue with waking from sleep mode when connected to external monitors.
With this one minor change, as well as the fact that the previous build was pushed to developers only five days earlier, it appears that the last version of Leopard is about to show up in Software Update. OS 10.6, Snow Leopard of course, is expected to ship towards the end of September.
TUAW wants to know when you think 10.5.8 will actually appear. Take our poll, and if none of the canned answers fit your thoughts, be sure to leave a comment.
