How to fix cannot log in to iMessage on Mac

The error of not being able to log in to iMessage usually appears when the user's Internet connection has an issue or the service has an error from Apple. This problem makes it impossible for users to send messages via iMessage even though they have logged into the previous account. 

What causes the error that I cannot log in to iMessage on Mac?

The main causes of this error:

  1. Internet connection : Both phones and Mac computers must have a stable Internet connection. Establishing a connection to the server and then retrieving personal information such as sending messages is not an easy task as you think. Therefore, a stable and high-speed Internet connection is absolutely necessary.
  2. Termination of service : In some cases, errors may occur because Apple stops providing the service. From time to time, the server needs to be checked and maintained, preventing any failure. The maintenance process usually requires partial or complete shutdown of the service.
  3. Date and time settings : Probably due to improper date and time settings, an error occurs. Date and time settings are important in establishing an Internet connection because server certificates are updated daily on the website. If the time is not right it will affect the certificate and the connection will be blocked.
  4. Account malfunction : Sometimes Apple ID also has some problems that make iMessage impossible to send. These issues can be easily resolved by starting the login process again. 
  5. Cache data is corrupted : All Macs use NVRAM to temporarily store frequently accessed applications or programs. This cached data sometimes causes problems and prevents computers from logging in to certain services, among them iMessage.

Here are ways to solve the problem of not being able to log in to iMessage on Mac.

1. Check the time

If the time setting fails, iMessage error may occur. Therefore, we need to reset the time in the machine, turn on the automatic time update mode.
