To help troubleshoot your Mac, I would suggest that you consider using EtreCheck and posting the resultant report for us to review.

You can download EtreCheck from here.
Start EtreCheck from a normal user account. Optionally, you can run it from a user account with Administrator privileges.
Select Options
- Verify that the two options: "Ignore expected failures in Apple tasks" and "Hide Apple tasks" are enabled." Note: They should be by default. You can skip this step the next time your run EtreCheck.
Select a problem from the drop-down menu to enable the "Start EtreCheck" button. Optionally, you can add comments on what issues your Mac is experiencing, especially to aide others with similar Mac issues.
Click on Start EtreCheck
Allow the program to run to completion.
When done, you should get a results report.
Select the "Share Report" icon.
- Select Copy Report
Paste the report to your reply post.
