Downloading and executing the latest build from the official website causes MacOS security to block it by default because of a code signing developer ID change:

Execute the command: codesign -dv --verbose=4 /Applications/BambuStudio.app Against previous versions and the current version This change is developerID leads tot he app being blocked on MacOS by default. Once its blocked I do not know how to unblock it.

When users see this dialog:

they must click "Accept Modification" or BambuStudio will be denied access to any network permanently, unless the user completely removes it, reboots and reinstalls it.

If the user navigates away or closes the app they will not see this message again in order to be able to accept the modification, unless they uninstall the app (drag to trash, empty trash) AND reboot the Mac and reinstall the Bambu Studio app.

I can't get the latest version to run also on my MacOS. I never saw the message in the above screenshot. I'm on a MBP with intel (last model that had Intel chip) and the app will launch but no main screen is presented. I tried going back to older version it has the same problem. I was running the latest version of Sonoma when I had this problem to start with and then updated to the latest beta of MacOS with no difference.

I tired going back to older version, I tried completely removing it and re-installing it .. same problem I can't use the app. On install it starts .. downloads the network plugin and then nothing. No main screen .. no errors.. no nothing.

Try removing entirely, rebooting, reinstalling.

[swheettaos]

I deleted the app (deleted from application folder) and rebooted and then reinstalled.. Same issue.

[swheettaos]

ok.. I was able to get it working .. it was some weird multi screen thing. I was able to the menu and resize it and it appeared.. didn't work from the dock .. had to use the menu item. Weird.

@swheettaos we have tried on lots of Macos laptops, can not meet this issue to help us to debug could you show us your OS and system information?

[JeremyLaurenson]

The solution for this was to remove the app, reboot and re-install the app

Then when you get prompted with the issue:



You MUST click “Accept modification” or it blocks Bambu Studio network access

Hello @JeremyLaurenson do you know any clue on how this issue can be reproduced? we have updated our macos to 14.5 today and still can not reproduce this issue

[JeremyLaurenson]

I would use an Intel Mac then: Remove Bambu Studio, reboot. Install an older version with the older code sign, and enable network. Then download current version, copy over old and launch it

Thats what gives me this error

@JeremyLaurenson The dialog you're seeing is from Little Snitch (a 3rd-party firewall), not from macOS itself. This is only an issue for Little Snitch users.

[JeremyLaurenson]

Aha! Thanks for the info, @Aaron-Rumpler Ill reach out to those guys to make sure they make this more obvious.
