Agreed. I'm thinking about going from SL to ML and don't want to wait too long before legal ML is gone.

When someone finds the system requirements of the Dev preview, please post!Just remember that the system requirements can change during the beta. Although the list of supported systems probably won't change.

If you buy it now on app store, you will be able to download it on your purchases tab. Lion still shows up on mine.

Probably everything with 256-Bit registers (AVX 1.0 and newer (http://en.wikipedia.org/wiki/Advanced_Vector_Extensions)). That means Sandy Bridge and newer.

No way. I say within the last 4-5 years

So not the Core 2 Duo? Yep, I'll be getting mountain lion before they take it off the App Store.

That means more work for me to do. :P I promise you Ill make 10.9 runs on ALL older Macs. Including those that ML doesn't support

Using your current method for ML, do software updates (like 10.8.4) break the installation?

I have a C2D, too with ML on a 256 GB SSD. But the C2D is the last one supported by ML so I would be surprised if Mav would still support it.

I'm not a developer, but this is the place where developers can download Mav and it's not yet online. The Mav preview will certainly contain a ReadMe with the system requirements in it. So until this site goes online or some developers find out at the WWDC, nobody besides Apple yet knows what hardware is supported.

I also have a C2D that was supported by ML. While the improvements in battery life sound fascinating, I will survive without the update. I'm not really holding out hope.

If it doesn't make the cut in the end, no worries. Mountain Lion is working OK for me.

Always appreciate MR humor. :D

Nice to see the same set of machines supported. Even ML runs fine on "unsupported machines" so although the new features are nice, that also seems to mean that they are doing some optimization in the code etc to streamline the way the OS works underneath with subsequent OS releases. Wish they would cut out the "artificial obsolescence" of older machines that would also run it fine, however I also realize they run a business and it behooves them to do so.

Thank You to the poster who posted the System Requirements.

Minimum RAM is definitely the same as Mountain Lion (2GB) because Mavericks installed fine on my baseline 2011 MacBook Air. :D

Well the test machines in the live stream, well the specs listed in the small text on the OS X page were on 4GB.

My understanding with ML is that it can run on 2 gb of RAM, but not as well as with 4 or 8 gb.

I currently have 2 gb and was planning to upgrade to ML after putting in more RAM. Not sure about "Sea Lion" on my 2009 MBP.

Anyone have an early 2009 iMac with only 2GB of ram running Mavericks? Curious to see if it will have any improvements over Mountain Lion. 10.8 is too laggy for me on it so I'm back to Snow Leopard until further notice.

Have you considered upgrading your anemic quantity of ram to 8 gb first?

I most definitely have, just hard to justify to the Mrs. why I need to upgrade a 2009 iMac when I have a perfectly fine late 2011 MacBook Pro.

I'd think it's 2gb since the earliest MBAs it supports shipped with 2gb standard.

Thats great. Hope Mavericks gives 2008 Mac Pro's another new life. Mountain Lion is great as it is but after seeing the WWDC that day and all the new features, it feels quite dated in a way knowing all the new features.
