Or maybe just badly programmed…
I’ve had this experience with multiple hobby programmed uninstallers, they would leave a folder behind. Sure no problem, I’ve got it for free, they can’t help it. You file a bug report and hope they fix it in the next release.
But when we talk about Apple, things are different. Apple is a respected company.
Yesterday I tried installing Quicktime to play my mp4 files. I downloaded the installer from the Apple.com website, and installed it. No problem.
But since the movies were damaged I decided that Quicktime was useless, and so I removed it. Or so I thought…
After inspecting my system multiple Apple related folders where still there. And even Apple Software Updater. I chose to remove Quicktime (the only thing I installed!). Then why must it not remove this application? Because it’s Apple? (that’s what they think probably…).
So you might want to watch out with uninstalling programs, they always leave stuff behind. Even with the most respected companies. Maybe they don’t deserve that…
