I use private modes of browsers. Is it really safe? (here I`ve read that private browser can not give you an absolute guarantee of online privacy and data security - https://vpnclientapp.com/blog/private-browser/)
I would also add one more great app, which I use when I need to find duplicates on external drive - https://nektony.com/blog/find-and-remove-duplicates-from-external-drive It works so fast, that every time surprises me)
There are 2 popular removal tools for Mac with almost similar names – AppCleaner and App Cleaner Pro and they tend to be mixed up by most users. Here is a great comparison chart of them - https://nektony.com/how-to/appcleaner-vs-app-cleaner-pro
there are 2 apps App Cleaner (https://nektony.com/mac-app-cleaner) and AppCleaner. Don`t confuse them. However, I like App Cleaner more as it has a better interface and allows to remove Remains as well.
