How do I stop EndNote from opening My MacBook

Please how to stop the endnote from automatically opening when I powering the pc (MacBook)?

While this isn’t a known issue for EndNote, I suspect I may know the reason.
In Word, if you go to the EndNote ribbon, and go to Preferences, there should be an option there to “Open EndNote when starting Word.” If this option is Enabled, it’s entirely possible that something like an Office Quickstart bar, which triggers Office programs to be loaded into memory for quick launch, could trigger the EndNote software to launch.
Try disabling this option, and see if it helps to resolve the issue.

If not, then I would recommend reaching out to our EndNote Support team. They should be able to help! Endnote

Thank you
I will try
