There are a few reasons why you might not be able to delete Dropbox from your Mac. The first reason is that Dropbox is part of the Mac App Store and is subject to Apple’s terms of service. If you uninstall Dropbox, then you may lose all your data in the process. Additionally, if you uninstall Dropbox and then try to use it again, it may not work because it was removed from the Mac App Store’s list of installed applications. Finally, if you uninstall Dropbox and then try to use it again, it might not work because there may be a conflict between the two applications’ files.
