Staff treed Posted October 9, 2019 Staff ID:1339189 Share Posted October 9, 2019 (edited) The issue described below has been fixed in Malwarebytes for Mac 4.0. If you are still seeing the issue where Malwarebytes Protection does not show up under Full Disk Access, make sure that you have upgraded to 4.0. You can download the latest installer from here: https://malwarebytes.com/mac-download Original problem If you have upgraded to macOS Catalina and have installed the corresponding update to Malwarebytes for Mac 3.9.32, you may see a problem where the app will tell you that you need to enable Full Disk Access. However, when you follow the directions provided, you will not see Malwarebytes Protection in the list where the directions say to look for it. We are still unsure exactly what changed, and whether this is a Catalina bug that will be fixed in a future release, or whether we need to change something. We are investigating. In the meantime, you can fix the problem by downloading the Malwarebytes for Mac installer and reinstall it manually. There is no need to uninstall Malwarebytes for Mac first, you can simply install on top of your existing copy. Once you have done this, you should see Malwarebytes Protection on the list of apps to give Full Disk Access to. Download the Malwarebytes for Mac installer here: https://malwarebytes.com/mac-download Technical background It seems that something changed between the Catalina betas and the final release, and it is triggered by installing the Malwarebytes for Mac update via the installer process located at /usr/sbin/installer, as opposed to the Installer app located at /System/Library/CoreServices/Installer.app. When installing via the former, Malwarebytes Protection will not appear on the list. When installing via the latter, it will. We have also observed cases where Malwarebytes Protection will disappear from the list, even though it has already been given Full Disk Access. Despite not appearing on the list, it will nonetheless continue to have Full Disk Access, and will remain capable of detecting and removing threats from locations that are not accessible without Full Disk Access. This is definitely a Catalina bug, which leads us to believe the other problem may also be a related bug.

alvarnell Posted October 9, 2019 ID:1339195 Share Posted October 9, 2019 I'm in Mojave at the moment and looking at my Catalina - Data volume there is no /usr/sbin, so I suspect what you see is actually a hardlink to the System's Installer.app. That could still be a Catalina bug, I suppose.

zyx017 Posted October 19, 2019 ID:1340530 Share Posted October 19, 2019 Hello Thomas, I have installed and re-installed MBAM on macos catalina but the prompt for full disk access still does not appear. I guess I will just wait until the issue is resolved. best wishes zeke Link to post Share on other sites More sharing options...

JRRRRRR Posted November 8, 2019 ID:1343838 Share Posted November 8, 2019 I have an issue with Malwarebytes on my Mac running Catalina. Although I have given Malwarebytes Full Disk Access (see attached screen shot) Malwarebytes continues to warn me to give it Full Disk Access. Is this a bug?

alvarnell Posted November 8, 2019 ID:1343840 Share Posted November 8, 2019 (edited) Start by upgrading to version 4.0. It’s a free update. You normally must restart the app, in any case, so the upgrade will take care of that for you. Edited November 8, 2019 by alvarnell Link to post Share on other sites More sharing options...
JRRRRRR Posted November 8, 2019 ID:1343844 Share Posted November 8, 2019 Did as instructed. Screen capture says it all. Anything else I can do? Link to post Share on other sites More sharing options...
JRRRRRR Posted November 8, 2019 ID:1343845 Share Posted November 8, 2019 Fixed it! Had to reauthorize Full Disk Access for the version 4.0. Thanks! Link to post Share on other sites More sharing options...
