Hello guys,

I'm about to purchase a 2013 iMac, I'm going to order a 27" with 256 SSD and upgrade the ram later.

If I buy my machine, and install Mavericks on it when it's out, will there be any performance difference at all between my machine and another iMac with the exact same specs bought with Mavericks as it's native operating system when it's released?

I know it's probably a needless question, but I'd just like to know as I don't have any knowledge of computers in this regard.

Thanks :eek:
 
There should not be a difference in performance, But if you are not sure about it you can always do a clean install of Mavericks on your Mac when it gets released ;)
 
No difference, in fact there will probably be an improvement as Apple made some good changes under the hood.
 
You could say the same thing when the next version of Mac OS (OS XI?) comes out. It's an endless flow of yearly updates. Like others have said, it'll probably boost performance - don't worry! :)
 
Thanks CCerta - I think I'm probably thinking about it for no reason, I'll just buy it and happily install Mavericks like a normal person!

Myflyn and Aaron - thanks a lot for your replies, it's my fault because my question is a bit ridiculous but what you've answered isn't what I'm asking!

What I'm talking about is for example, two late 2013 iMacs, with the same same specs. Would there be any performance difference between one machine that had a native install of Mountain Lion and then later upgraded to Mavericks and another late 2013 iMac with the same specs that had a native install of Mavericks?
 
is there another way to buy Maveriks beside putting your credit card on your Apple ID ?
 
Hah this thread has been derailed somewhat ... Haha I don't mind, just passing comment!

There will be no difference whatsoever because they are the same exact machines in all hardware aspects.

Your iMac would perform the exact same way an identically-equipped iMac that came with Mavericks would.
 
Ah I think he's asking the difference between upgrading to 10.9 vs. clean installed 10.9 There really shouldn't be any noticeable difference. OSX upgrades are pretty good about that. Unless you really have tons of crap everywhere, then maybe you want to just clean install 10.9 I clean installed on my MacBook since it was my first Mac and I had messed with a ton of stuff.

There will be zero difference in operation or speed. Older versions of OS X had two types on install, one was an upgrade and other was an archive and install. The first type (upgrade) would only replace what had changed and did leave bits of the old OS in place. Newer versions of OS X are all similar to the old archive and install. By that I mean the entire old OS is set aside and replaced with the new one.
 
Actually there might be another reason to wait:

On every new Mac (at least as far as I know) you get the newest iLife package installed.
If they release a new one with Mavericks you would still have the old one when you upgrade.

So if you don't need it yet, you could wait for that.
Also, if you are on the fence between MacBook Pro and iMac, you might want to wait until October 22. and see what new updates there are.
Those are the reasons why I am still waiting to order my 27" iMac :)
