Nothing Sweeter


I watched as the storage on my harddrive slowly ticked away byte by byte. I was afraid there was some form of malware on my MacPro. I disconnected from the internet to make sure nothhing malicious was being dumped onto my machine and still my storage ticked away. On deadline, I hoped I could get finished with what I was working on before the inevitable happened… but no. First the Adobe products ran out of scratch disc space. Then… everything crashed.

I had investigated and my user folder was the blossoming culprit. Furthermore, it was mail preference files in the library that were growing like demon spawn. Afraid to dump them, I deleted a few folders to make room for Dr. Cleaner…. downloaded, ran the app and presto, those killer files were gone and I had nearly half my storage space back. I upgraded to Pro – the price for the upgraded was nothing compared to the amount of time it would have taken me to figure things out on my own. Plus, the additional features seemed pretty sweet.

This is an invaluable tool – fast and easy to use with a beautifully designed interface. If the developers are reading this, you saved me today and to that I say thank you.

Excellent tool for speeding up your MacBook!


A lot of experts say that nothing is needed to clean or speed up your MacBook. I’ve come to believe that they’re sorely mistaken. My MacBook Pro (Late 2013, 4 GB RAM) seemed to be getting slower with time, and I needed some way to check and make sure everything is still working correctly. Not only does this Application speed up your Mac by freeing up RAM; it also cleans temporary files (for example; tmp, txt, log files, plist files, and other temporary files that take up space), and it does a plethora of other useful things. I would not hesitate to recommend this tool to anyone, as it has become the cornerstone application for me in the past year. 10/10 from me!

DONT DOWNLOAD: Completly messed up my file system


The UI is fantastic. It’s a shame this app seems to do the opposite of what I downloaded it for. Not only did this not clean my computer but it actually duplicated a lot of files. Even files nested deep inside directories. My dev envirnoment for the app im building is completly screwed up since everything from basic files to dependancies have been duplicated. This app even seemed to revive files I thought were long gone and threw them all on my desktop so that took a while to orginize as well. All in all way to much of my time has been spent fixing the damage this app has caused and I think I’ll just clean my computer manually from now on. The only reason I can see why this app has so many 5 stars after screwing my mac so hard is that they are bought. DONT DOWNLOAD!!!
