Really...
Instead of just making a casual statement, why don't you just post the actual install procedure here, then.
Also, the 2006 models really do not have sufficient RAM specs to run Mavericks well.
So, I seriously question that your 2006 model iMac is running well on Mavericks.
2006 models could either take 2 or 3 GBs of RAM (you can install 4 GBs of RAM to take advantage of more efficient RAM processing of matched pairs of RAM, but the hardware will only recognize 3.2 to 3.4 GBs of that total RAM). This is barely the needed "real world" "working" minimum of RAM needed for Mavericks to run adaequately.
New iMacs ship with a much better 8 GBs of RAM.
