I got a free trial code on a software called Trend Micro when I purchased my Mac and it worked well. However, I accidentally deleted the software when I cleaned out my library folder last week. The app only shows an icon on my Mac and I can’t use it anymore. I want to completely uninstall it now, but I can’t do that since I deleted the file. What should I do to completely delete the app?
From your description, I think you’ve just deleted some of the files of the app installer from your library folder, making the program either run properly or be uninstalled.
Since it is so, I suggest you go to the library folder to find everything about the software and delete them. This can help you uninstall the program from your Mac.
Why not use an app uninstaller to help you? Those third-party app uninstallers are designed to help us completely uninstall apps on Mac that cannot be manually uninstalled. I have used CleanMyApp, a freeware recommended by my friend. This tool helps me uninstall the stubborn apps from my Mac, including the app’s hidden files. You can try to use it to help you clean up and completely uninstall your unworkable Trend Micro.
