macOS 11 Big Sur - "4D" Database access error

adminUTM

Dear Support,

we are using EAP on MacOS Big Sur : all was fine for us. Since two weeks ago we cannot access to our application Database "4D".

To find the options who create the error to access to our 4D DataBase : we created policies to bypass "ALL" security modules and it's running fine!

After that we tried to enable module by module to determine which options could create the error, and we are surprise to discover we have the error as soon as we activate one of them.

For exemple we activate ony the peripheral control "Monitor but do not block" and we are not abble to access to our database

What is the link with the peripheral control...?!

Thanks for your update.

    We are experiencing problems with 4D and Mac OS Big Sur. We have a custom, non-built application. When we open files that are located on our Synology NAS they open as write-protected. We opened a case with 4D and I have a lot of back and forth with them. Too much to share on here. I have another ticket open with Sophos for Adobe InDesign files that open READ-ONLY from our NAS. For the Adobe problem we have a policy that has Cryptoguard disabled. For 4D, we either have to open the file locally or uninstall Sophos. here is the thread I started for InDesign: https://community.sophos.com/intercept-x-endpoint/big-sur-eap/f/discussions/126631/big-sur-11-2-3---intercept-x-10-0-4---adobe-indesign-opening-files-as-read-only/465819#465819. Sophos latest response was about OPLOCK: 

    Hello Jeff,

    This seems like an InDesign issue and should be brought up with their support team.

    Our investigation suggests that InDesign is likely not waiting for OPLOCK to be released on a file before opening it, hence it can only work in read-only mode.

    Cryptoguard may be incidentally adding additional wait time before OPLOCK is released by the system, since we're touching the file, but we're not directly affecting InDesign's file access logic at all.

    Most applications check the OPLOCK status and wait until they have write access before opening a file.
