Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
It sounds like this issue is happening on your mac, and not an ipad or iphone. To get started, whats the OS version on your mac?
You can check as follows.. Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
And also, it may be best if I connect to your mac directly via secure remote assistance, so I can fix the problem directly.
If youd like to try that option ( which is guaranteed fix or you will get a full 100% refund ), then accept the offer I am sending you now and then I will send you the connection steps.
