I am not able to understand how a 3.7GB install image can later fit into a 650MB recovery HD partition (and if it somehow could through some compression magic, then why not compress it even before to only give me 650MB to download from the app store)?

My total guess would be that the 650MB image just provides you a mechanism to download Lion again. Or perhaps it's a machine-specific rev? My instinct says the former.

Yup, your guess is right. Lion will be downloaded again if you install from the recovery partition.

The recovery partition doesn't need to contain the entire OS.

but there is also an option to install Lion from that recovery HD partition.

I want researchers to come on G+

any news on whether it is for 64-bit processors ONLY? my core-solo mac mini wants to know :-S

Lion is 64-bit only. Although the early minis have socketed CPUs, so you could theoretically replace it with a Core 2: http://www.xlr8yourmac.com/systems/mac_mini_core_2_duo_swaps...

oh! good to know!

According to Apple, your Mini isn't supported under Lion: "Your Mac must have an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor to run Lion."

I have a Core Duo-powered Mini and am in the same boat. That said, my Mini is at least five years old, and I don't think it's at all unreasonable for Apple to focus their limited resources on more modern machines. Besides, my Mini is running Tiger in a data center, so I'm not losing any sleep over not being to run full-screen apps on it. ;)

Incidentally, pretty much any Linux distribution will support your slightly-older Mac Mini as though it were brand new.

Yes, it is 64 bit only - Core 2 Duo or newer required.

is there a way to collapse code?

I am wondering, if Unity isn't supported due to lack of hardware acceleration, does it fallback to Gnome2? (does it mean it still bundles Gnome along with Unity?). This is essential to make a choice between Xubuntu and Ubuntu when running in a VM

Yes, it does fall back to "Ubuntu Classic", how it is called.

aargh! I just installed it in Vmware Fusion on Snow Leopard only to realize it does not support OpenGL for Linux OS. Ubuntu went into a fallback mode and disabled Unity. Seems like I need to switch to a different Virtual Machine Software, any suggestions?

I really love Oracle's VirtualBox and use it daily for my dev environment.

Oracle's VirtualBox. Sad remembering the day Sun set.

I don't know about VirtualBox and OpenGL, but I just installed Parallels and everything works swimmingly! Better native partition support and what seems like very good OpenGL acceleration.

I also got native partition booting working very quickly in Parallels - I can boot both my native Windows 7 installation and my native Ubuntu installation - that are On Partitions Of The Actual Hard Drive. Took a tiny little bit of nudgework, but now it just goes.

Sorry to hear it wasn't voted up. I suspect HN has an aversion to direct link to video in submission.

no fullscreen mode for safari?

Safari does fullscreen just fine from my own testing.

suggestions for a mobi viewer for Mac OS X?
