Hi all :)

I have a late 2009 white unibody Macbook, and I have a question: is it possible to totally sweep the harddrive and do a fresh install of OSx mavericks or Yosemite? Originally the Macbook came with 10.6 (Snow Leopard). Original specs, didn't alter or upgrade components.

The reason I ask this, while working and surfing on the Mac is still possible starting up is taking quite a while and some apps take their time to start as well. Working with apps still goes fine, sometimes a bit of a lag. I think it is from upgrading 10.6 to 10.7 and 10.8 with apps and documents in place. So would I benefit from a fresh install? Or would I also need to bump up my memory to 4gb? Or is it better to save that money for a new Mac in the future? It still works good though.

Thanks in advance :)

I have the same mac as you with a 1tb 5400rpm hard drive and 4GB of RAM. I believe I have OS X 10.10 consumer beta 3 installed and I gotta tell you, it actually runs better than I expected. Apps do take a wee bit longer to launch, but it doesn't feel like much. There isn't any lag at all on my machine, But I do have 4GB of RAM. Since you have only 2GB of RAM, I advise to stay away from Yosemite at all costs until you can get that 4GB of RAM installed.

Thank you :D

But how can I do a fresh install of Mavericks without installing Snow Leopard first, that originally came with my Macbook? Is that even possible?

If you are suffering slow start-ups and apps lagging I would suggest replacing the hard disc before you install 10.10. It sounds as if the disc is failing and installing a new OS is about the worst thing you can do to a disc (constant writing to it for 30-45 minutes),

Upgrade the ram to at least 4GB and google Yosemite usb installer and follow those instructions to do a fresh install of Yosemite.
