There are three ways to access MacOS remotely: allow remote logins from another computer, enable Screen Sharing or allow access by using Remote Desktop. Both ways are legitimate, but if you don’t remember doing any of them you need to know how to turn on and off those possibilities.
Computers that run MacOS as an operating system can log in to your Mac using Secure Shell (SSH). Steps to enable remote login are the following:
Once Remote Login is enabled then users with access can use SSH to log in and browse your computer’s contents.
If you need help from IT to make changes on your MacBook or maybe you are collaborating on a project and want to share your screen you can enable Screen Sharing. Steps to enable as follows:
Now on another Mac (from which you want to access to your Mac) start Screen Sharing app. You can start it by clicking Command and Space buttons. How do i save image on mac.

As we’ve seen already remote login or sharing options require assigning access roles to the local users. If your system was hacked it is very likely that the hacker has added a new user to access it. To find out all users in MacOS perform the following steps:

In order to find when the user account was used to log in last time type the following command into the Terminal:

For each account, MacOS will list the times and dates of logins. If the login to any of the accounts happened at an abnormal time, it is possible that a hacker used a legitimate account to log in.
