Can't find where macOS FUSE is on my system to uninstall and update it
It is likely that you normally uninstall applications by dragging and dropping their icons to the Trash. In the case with the FUSE software program, you will not find its icon in the Applications folder, as FUSE is a type of extension. You will find its icon in the System Preferences window. However, it also consists of numerous user-space libraries and tools, which should be removed as well. 


Open System Preferences and click on the FUSE icon. 
In the window that appears, untick Show Beta Versions to prevent leaving the remaining files of the FUSE preference pane after its deletion. Then, click on the Remove FUSE button. 
Within the System Preferences, make a right-click on the FUSE icon and select Remove “FUSE” Preference Pane. 
As you know, every application creates plenty of service files.It is very likely that some types of files were not deleted with the Remove FUSE button. Usually, the service files of applications are stored in the user’s Library folder. To get access to this folder, open Finder → in the menu bar, click Go → Go to Folder → in the window that appears, type ~/Library and click Go. Within the user’s Library folder, find and delete unneeded files, related to FUSE in the following directories:

~/Library/Caches
Also, I recommend that you check other subfolders in the Library folder. If you find files related to FUSE, remove them to Trash.

~/Library/Logs

~/Library/Preferences

~/Library/Application Support
