Hello! I've a bit of an issue here. It seems the old dock flags, namely Code: contents-immutable position-immutable size-immutable autohide-delay autohide-time-modifier don't work in Mavericks... At least in DP5. I can create the values manually (via Xcode), but after a while (and killall Dock) it seems the values are deleted. Is there a solution to this? I honestly cannot stand having to hold my mouse to the dock for one second. Neither can stand the tediously slow animation... To my knowledge it worked in previous DPs... but when I updated to DP5 this morning, the iBooks app was added to the dock. And I couldn't remove it. It happened before so I just launched terminal, deleted the contents-immutable tag (that I've had from 10.7 to 10.9 DP4)... and tried again. It didn't work, so I trashed the dock preferences... and it worked. But of course, now it's not locked, but it's not my greatest concern, the speed is. Thanks! EDIT: Alright, this's the last straw. No iCloud application works! Keynote, Pages, Numbers, TextEdit, Preview and pretty much every iCloud application takes forever (i mean literally) to start. And when it does, the open file window is broken. The 'On my Mac' screen works fine, but... the 'iCloud' tab simply shows a copy of the On my Mac screen (albeit without file browsing toolbars). This is a serious problem. It could be an issue on my end though, my iCloud.com doesn't have the new iOS7 layout yet. It's crippled my productivity by a huge amount. iWork for iCloud is simply too unwieldy (and doesn't have my fonts) to use. EDIT: at this point it looks like Apple is stuck in-between transitions: I can see iOS-style folders and things when in icon view for iCloud (but it's still browsing my local drive)... This is bad.
