Not really but IF you own a Mac then you NEED to own this little utility.
Cocktail is 50% off for the weekend
It uses utilities that are built into the OS but very hard to get to on your own do all kinds of important maintenance tasks that none of us ever get around to doing.
You can use it on a regular basis or be lazy like me and just run it when things start to feel a bit off. Apps running slow, stuff crashing that didn't. 99% of the time Cocktail will fix it, and for $10 it's worth getting now, you will want/need to get it or something similar eventually and at full price it's the frugal choice.
