Apple has also seeded the GM build of Xcode 5.0.1 for building applications for Mavericks.

Apple is reportedly targeting a late October launch for Mavericks, with the company starting to train AppleCare staff on the upcoming operating system this week. Sources have indicated that training must be completed by October 11.

Update: Apple has also seeded developers with an iPhoto 9.4.7 update that "addresses an issue that could cause iPhoto to quit unexpectedly on launch when running OS X Mavericks GM Seed."

Recent OSX versions have had to be purchased. I don't see any reason why this would be any different.

If you can't see the merit in paying a nominal fee of $20-30, then don't upgrade.

It's funny how people complain about paying $19.99 for ML. Guess they weren't around to pay $129 for Leopard

I will STILL say I think it's gonna be free.

I think so too. Just so Apple can get everyone to upgrade.

It should be free.

Should? Really?

I mean while we're making demands, I think Apple SHOULD pay me one million dollars to install it.

Nope. There are so many enhancements and improvements in Mavericks that any true Apple fan should be willing to pay an upgrade fee to support the Mac platform. If we don't support the Mac with our money, Apple could abandon it sooner than we want - keep that in mind when making demands for free stuff.

Does that mean developers get Mavericks for free?

We pay $100 per year to keep the Dev. account.
