    Is someone running Maverics on older machine? I have a MacBook Pro with 2.4 GHz Core 2 Duo CPU and 8 GB RAM. Maverics is optimized for the newer Intel CPUs. I wonder if the new OS will run on this old machine fluent and fast like the 10.6.8 i am currently using.

    It runs beautifully on my 2007 2.2GHz MBP with 4GB of RAM.

    Ι have a late 2009 iMac with intel core 2 duo and 8gb of ram.

    This Machine runs Snow Leopard beautifully and I did not upgrade to Lion/ML because of the feedback I received.

    Should I consider Mavericks now? Will it run as good as my Snow Leopard has?

    I think there is a lot C2D users asking the same.

    May be a good idea making this topic alive.

    I have a 2008 C2D iMac and I'm waiting more news about 10.9 on these machines. Until that, I'm still using 10.6.8 that is a quite nice system. :apple:

    Fantastic on my late 2009 13" MacBook (the last white unibody model). I have 8gb of ram and a 7200rpm hard drive in mine, but I'm getting a bit better battery life and it is running really great.

    works perfectly, better than lion and mountain lion. I guess is as good as snow leopard. I run a SSD, so it really flies. very very fast.

    Mavericks runs very well on Early 2008 20" iMac: Core 2 Duo 2.4 GHz, 4GB RAM, Radeon 2400XT.

    Maverick runs perfect on my entry level Late 2009 iMac 3.06GHz MBP with 12GB of RAM.

    I started with Snow Leopard, upgraded to Lion, then Mountain Lion and now Maverick. It runs just as fine as always.

    Did anyone run a benchmark in 10.6 and 10.9 ?

    I already know that 10.7 and 10.8 are slower but I didn't heard anything comparing to 10.6.

    I'm pretty sure that doest worth to wait for some updates to fix some bugs. I'm sure they are going to be released very soon.

    Yeah, it's running very well on my MacBook 5,1. The battery life improvement is noticeable. No lag on anything after indexing my system.

    Also seems to run much cooler when handling flash.

    2009 iMac i7 benched something like 8500-9000 back in Snow Leopard days.
    That same mac benched 10265 yesterday after Mavericks was installed.

    My wife's 2009 iMac Core2duo 2.93 ghz benched 4730 under Mountain Lion
    It benched 4681 right after installing Mavericks but it was indexing the drive at the time so I'd expect the actual bench performance post indexing to be higher at this point.

    MacBook Pro 13" mid-2009 here, and Mavericks has been smooth for the day and the half since installing it.

    Runs good here but iMovie cannot install for many.

    speed is fine but video performance is very poor, but that may just be Flash and VLC needing updates

    Late 2008 iMac 2.4 with 4gb of ram here, so far the only issues I've had is that Mail is a pile of ***** and runs very badly. Ive had to turn off messages in Spotlight to stop it from taking 10mins to load up. This is after a complete overnight spotlight database rebuild.

    Works like a dream on my 2010 13in MBP. I was considering buying a new laptop but after installing Mavericks I think I'll hold off for a while. The computer feels new...

    Late 2008 MBP Core 2 Duo 2.4 and 8 gb ram and it works beautifully. Very very well optimized and I almost second guessed upgrading to the new rMBP.

    I'm running it on my 2009 MBP with 2.66 GHz C2D and 8GB RAM, and its a dream! My MBP was already pretty darn fast since I take good care of it, in fact its usually snappier than my 2011 i5 iMac funnily enough.

    Since installing Mavericks, animations seem a lot more smooth and apps are more quick to respond. I have yet to see any drop in performance and I've been using it a lot. I've run a ton of apps and seen almost no slow down at all. It tends to run cooler than ML too, with general CPU temp below 50 degrees when using finder, safari, mail and a few other apps.

    Everything just seems more smooth and snappy, and its all very fast. I literally have no reason to upgrade my laptop any time soon.

    Early 2008 MBP here 2.5 GHZ core 2 duo with 4GB of ram. Runs extremely fast. I do have a samsung SSD 830 though which helps :D

    2009 MBP with at least an nVidia 9400GT…? Darn thing is, my 2010 15" MBP that comes with the original Intel HD Graphics, I find Mavericks animation stutters like there's no tomorrow. Mountain Lion animation is smoother, but with Mavericks… :confused::confused::confused:

    Yep, I have the model with the 9400M + 9600M GT. I usually run the integrated graphics and have no issues.

    2010 Macbook Pro C2D

    2.4Ghz C2D, 8Gb Ram, 128Gb SSD, 2010 Macbook Pro:

    Updated to Mavericks and running very well.

    I also have a (2011) Mini 2.3Ghz i5 with 8Gb ram, & 750Gb Hybrid Drive. Both machines running perfectly. As a matter of fact I see better battery life and better Ram management on the Macbook now.

    (edit) I did a "clean" install on the Mini, but updated on the Macbook Pro (over Mountain Lion) and see no difference between the two.

    The scrolling and general UI animations and behaviors actually seem better than ever on my Late 2009 Mac Mini core 2 duo with 8GB of RAM. I've run Snow Leopard, Lion, Mountain Lion on this machine before Mavericks, and it feels better than ever. Delightfully surprised!
