See the note about sandboxed macOS apps in the Flutter tab of https://docs.objectbox.io/getting-started#create-a-store

Note: I labeled this issue with "more info required" so it will auto-close in a few days if there are no follow-up comments.

Hi @greenrobot-team , I did changes according to https://docs.objectbox.io/getting-started#create-a-store
It is running release build in my system.

But when i am uploading to TestFlight. It is giving below error-:

Invalid code signing entitlements. Your application bundle’s signature contains code signing entitlements that aren’t supported on macOS. Specifically, the “[group.XJQAE4L5HQ.mf]” value for the com.apple.security.application-groups key in “com.magic.macfalcon.pkg/Payload/mb_mobile_hybrid_apps.app/Contents/MacOS/mb_mobile_hybrid_apps” isn’t supported. This value should be a string or an array of strings, where each string is the “group” value or your Team ID, followed by a dot (“.”), followed by the group name. If you're using the “group” prefix, verify that the provisioning profile used to sign the app contains the com.apple.security.application-groups entitlement and its associated value(s). (ID: e7524981-8b6c-498d-90d1-da5e897d624a)

My Debug and Release entitlements file as below

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

This value should be a string or an array of strings, where each string is the “group” value or your Team ID, followed by a dot (“.”), followed by the group name.

Sounds like group.XJQAE4L5HQ.mf, specifically .mf, is not a valid value.
