Reviving white macbook (Early 2009) I'm trying to revive my old college laptop which is a white macbook from early 2009.  I pasted the hardware a software specs below.  The last thing that I did with it was update it to Mountain Lion, which turned out to be somewhat of a mistake because it is now painfully slow (which is why I haven't touched it in a while).  I'm looking for suggestions for how to bring it back up to speed.  

Here's what I have in mind:


Update the RAM.  4Gb at least and 6Gb if possible
General cleaning.  I'm considering CleanMyMac 2, but I'm not sure if the gains I    get from it will be worth the $40.
Lastly, I'm considering upgrading to an SSD.


Thanks in advance,

If you really want to make your old mac happy I would say the best thing is the SSD. It will make it feel faster than it was out of the box and that is because it is. A RAM upgrade isn't really necessary and I would suggest investing that money over into a new battery. If the unit hasn't been used in a good long while chances are your battery will be dead or inches away from death.

A new battery (directly from Apple) will be guarantied for a year and will give you a notebook to take with you (using an SSD instead of a HDD also gives you a few extra minutes in battery life.

CleanMyMac is not recommended! Instead install a new OS on the SSD and then using an external enclosure transfer the data via Migration Assistant. But always make sure you have a backup of your files. 

Honestly I am more of a fan of keeping things fresh and installing 3PP programs fresh too and manually dragging over your documents, pictures, music, etc.
