I use Malwarebytes & Dr. Antivirus on both my iMac27 and MacBook Pro. Any known issues wit those?

For what purpose do you use those? Are you trying to prevent malware on your iMac and MacBook Pro, or protecting those who may receive files from you from malware?

Reasonable practices should prevent malware altogether on your Macs...
