I have been using my macbook to develop number of websites for the past 2 years. In the process I installed a number of applications, that I hardly used. When I deleted those application, the traces of those applications still lingered around. When I checked the RAM available for use, out of 4 GB, I always, only had 17 MB left to use.
As a result, all my applications took longer to process, my work got slower and projects took longer to complete. I would sit dwindling my thumb when the page took forever to load. When I shared screen with clients, the sharing was really slow and consumed too much time. It was embarrassing until I came across MacPaw. Using this tool I was able to scan my mac for all the left over unused files, delete unnecessary large size files on my laptop and free up RAM instantly without losing anything important.
