I have CCleaner Free 1.15.507 running on a Macbook Pro. I have used CCleaner for years without trouble. I went to run it and it asked me to upgrade to 1.15 so I did. Now whenever I run it, it hangs at 93% while looking at Google Chrome Internet Cache. I have uninstalled and reinstalled CCleaner, rebooted, done all the basics. This is the screen where it stops working. Any suggestions?
