Anyone for drinks?
“Cocktail is a general purpose utility for OS X that lets you clean, repair and optimize your Mac. It is a powerful digital toolset that helps hundreds of thousands of Mac users around the world get the most out of their computers every day.” Maintain.se
What can I say it does what it says on the tin. A excellent free peace of software which puts some extra life into your Mac. It has lots of features like showing hidden files to indexing your spotlight. The two options I use a lot is the cache clear out tick box and the purge the unused ram. It will ask you for a reboot and this does take awhile to reboot as its building up the cache.
Cocktail works from 10.7 upwards which is great news of legacy OS systems.

Here is another link using softonic website for downloading. I personally shy away from these kind of sites as they seem to have extras bolted on to the installer. If your not careful you have installed some extra bit of software you did not want or need.
