Apple Releases OS X Mavericks Developer Preview 5 with iBooks App

Apple has seeded the fifth Developer Preview of OS X Mavericks to developers, approximately two weeks after the release of the fourth developer preview. The release comes as Apple continues to work on restoring full functionality to its Developer Center after bringing software downloads back online last week.

This build, ignoring the normal "Safari is snappier" jokes, is ridiculously fast. I don't know what they've done under the hood, but damn they've done a good job of whatever they've done.

Preview doesn't sync with anything on iOS. They should just kill it and roll all its features into iBooks.


Including things like opening and editing graphics files? That would be an odd addition to iBooks.

How is IMAP better than pop3 anyway?

Edit: I mean functionally. I can read the Wikipedia article.


IMAP keeps items in sync across multiple devices. Read it on your phone, it gets marked as read on your desktop. Move a message to a folder, and that's reflected across all your devices.

POP3 creates a new copy on each devices that needs to be managed separately. It's effectively useless if you actually want to manage your email across multiple devices.

Look it up. I think ML had 4 DP's, no?


L and ML both had 4, but it's not like Apple says, "OK guys, we need 4 arbitrary DPs and then we can release it!" There will be as many DPs as they need.

They need to stop tying Safari to OS releases, then maybe it wont suck so bad. Both IE and Safari tie their new features to a new OS and they both suck really bad for it.
