I'm a Windows user, but my church uses a Mac to run its projection and video recording. I'll admit it works pretty well for what we typically need it to do, but it recently took me like five minutes to figure out how to crop a picture because you apparently can't do that by simply opening the file and clicking the crop icon.

Mac's filesystem is an absolute mess, too. This might just be my own inexperience, but I've saved things like PowerPoints and videos in order to upload them, and then I'll go to the website to upload them, and I won't be able to find them because they're not in a specific folder or something.
