3. After you sign out, sign back in with the same Quicken ID.

There are some instances in which Quicken simply needs to be closed and reopened for the Sign-in screen to load. Try this a few times before moving on to the next steps. 

1. Close Quicken.
2. Launch a web browser.
3. Go to the Quicken My Account login page. If the webpage appears, then the system can connect to the Quicken ID server. If the webpage cannot be displayed, follow internet connectivity troubleshooting.

5. Click Turn Off Firewall.

1. Check to see if there is a hidden Administrator account on the computer. 
   
   1. Go to Settings > Accounts.
   2. Select Family & other people. 
   3. Verify there are no hidden users. If there are none, please proceed to the next step.
2. Create a new user administrator on the computer.
   
   1. Choose Apple menu > System Preferences, then click Users & Groups.
   2. Click the lock icon to unlock it, then enter an administrator name and password.
   3. Click Add (+) below the list of users. Click the New Account pop-up menu, then choose a type of user.

Administrator: An administrator can add and manage other users, install apps, and change settings. The new user you create when you first set up your Mac is an administrator. Your Mac can have multiple administrators. You can create new ones, and convert standard users to administrators. Don’t set up automatic login for an administrator. If you do, someone could simply restart your Mac and gain access with administrator privileges. To keep your Mac secure, don’t share administrator names and passwords.

4. Enter a full name for the new user. An account name is generated automatically. To use a different account name, enter it now—you can’t change it later.
5. Enter a password for the user, then enter it again to verify. Using a password hint is recommended to help the user remember his or her password.
6. Click Create User.
