It worked!

After trying to do a lot of manual cleaning myself, I still needed to free up space on my drive. I did the one-click cleaning on this service first, and that cleared up about 2 GB. Then, I used all the "Optimization" and "Manual Cleaning" options and was able to free up about 45 GB of space. Mostly in old iPhone backups that I didnt need anymore. What a relief! It was fast and easy. Heres hoping it was safe to use — so far, so good. (Posting day after the cleanup). THANKS for the free software, guys!
