I use mpv on macOS and haven’t had any trouble to speak of. But you might have installed VLC from the App Store, which is a common mistake—unless you’re installing Apple’s own software, you probably shouldn’t use the App Store. It usually only carries inferior versions of the software to comply with Apple’s terms, haha.

I very rarely use Microsoft Office nowadays, but once it’s installed, it’s (mostly) fine? I’ve heard from a coworker that there are some significant missing features in some software in that suite. I just remember struggling to find the page to download the Setup.exe file. I went to the exact same page in Microsoft Edge and a download button that wasn’t there in any other browser suddenly appeared! Maddening! This was a 5 or 10-license verison, I think.
