[Scan Date not being updated]

Thank you, mikeknh, the reboot worked. I should have tried this earlier.

I have done everything you suggest, except the reboot. I will give this a try. Thanks.

We've seen a few similar cases, and a reinstall always seems to fix it. However, we'd like to better understand what's going on. If you're willing to send us some additional information, run the attached script. It will create a file on the desktop called MalwarebytesInfo.zip. Please send that to me via a direct message.

Get Malwarebytes Info.zip

I downloaded and installed your "get malwarebytes info" utility and ran it. The result is attached. I have uninstalled and reinstalled Malwarebytes for Mac, Premium, and still do not get the scan date to update. Still saying "never happened".  Previously it was stuck on October 20, 2017. I have Malwarebytes for Mac installed on another iMac and a MacBookPro and this doe not occur. What can I do to remedy this?
