Not sure if I can blame the weak amount of vram Radeon 4670 256 chip and my nearly empty 500gb magnetic hard drive in my 2010 iMac on all too frequent beach balls in Mavericks. My iMac has 12gb of RAM and it flew on ML 10.8.5 even with the hard drive half full and the weak vram.

A clean install of Mavericks did zilch for me.

Wish I waited to install this on my iMac.

So for laptops it might be great, but in this iMac users case, it was not.

You can blame it on the rotating platter of that HDD of yours. Even if you have 64GB of RAM, you can still frequently get beach balls if you don't have an SSD. I tried this on my Mac Pro before.
 
You know that is the funny thing, I have yet to see a spinning beach ball. Honestly it is I feel a hair faster than ML10.8.5, except for safari. All of my apps, except one web browser has to be updated. Like I said I have the entry level, and it is awesome. I will admit when i read these posts and how some of you are into these macs,I almost feel that I should not even waste your time with these questions. Your knowledge on this stuff is awesome.Thanks again.
 
it's unfortunate

The beach balls and other mounting problems (a lot of blue tooth connectivity etc.) are making me rethink my upgrade time frame. Restart time is much slower on Mavericks too.

Ah well. Thank goodness I have the $ and a job to upgrade.
