Mac OS X Lion Dev Preview 2 Update Released, Developer Preview 3 Soon?
Update: Updated with direct download links for the DP2 Update 1 packages – these files are only relevant for developers with DP2 installed.
An update to Mac OS X Lion Developer Preview 2 has been pushed out via Software Update. The download comes in at around 1GB and changes aren’t specific other than being “recommended for all users running Mac OS X Lion Developer Preview 2.”
What about Developer Preview 3? Alongside the DP2 update, an accompanying XCode 4.1 update includes a reference to “support Mac OS X Lion preview 3,” suggesting that Lion Developer Preview 3 may be released in the near future. XCode 4.1 preview 3 is a required update if you plan on building any software in Lion DP2.
Mac OS X Lion Developer Preview 2 was released to developers on March 30, I found the update to be less stable and more resource hungry than Developer Preview 1, so I haven’t used it much. I’m hoping this update resolves some of the memory leaks that appeared in Developer Preview 2, although not all machines seem to be affected.
As always, backup your Mac before installing system updates. This is especially important when using a beta OS, which is also why I’ll continue recommending the dual boot method if you plan on trying out the Lion preview releases.
Lion Developer Preview 2 Update 1 Package – Direct Downloads
Here are direct download links from Apple for Dev Preview 2 Update 1 Package installers. These do NOT contain the full installation of Lion, only the update package released today. If you’re not a developer with Dev Preview 2 already installed, these won’t be of any use:
Lion Client DP2 Update 1
Assuming you dual boot between Mac OS X 10.6 and 10.7, all you need to do is download the appropriate Lion DP2 Update 1 package file within Snow Leopard and copy the .pkg file to your Lion partition for installing later in Lion. This is a much easier way to handle updates if you rely on a stable 10.6 installation for most of your work and just boot into Lion for 10.7 specific development.
These links were found on MacRumors forums (thanks David) and are really helpful if you want to download the update from 10.6 to install later in 10.7DP2.
Heads up to MacStories for noticing the Dev Preview 3 reference in the updated XCode 4.1′s change log.
