Big Sur will allow lightburn to open

LightBurn Software Questions OS Specific
1

Have upgraded my mac to Big Sur 11.5.2. Firstly the installed software did not carry over.

So have downloaded and reinstalled.

Please could you advise as how to instal or where to get an updated link to download.

When i try to open it I get this error message.

“LightBurn.app” can’t be opened because Apple cannot check it for malicious software.

This software needs to be updated. Contact the developer for more information.

This item is on the disk image “LightBurn.V1.0.01.dmg”. Safari downloaded this disk image today at 13:31 from github-releases.githubusercontent.com.

MacOS Installation

  1. Double-click the LightBurn.dmg file to mount the disk image.
  2. Drag the LightBurn application into your applications folder
  3. Eject the LightBurn disk image, or drag it to the trash bin

Please note that at this time, LightBurn for MacOS is not digitally signed. This means that you will need to tell MacOS that you trust us. (Read about this here: Open a Mac app from an unidentified developer - Apple Support)

To launch LightBurn for the first time:

  1. Open a Finder window
  2. Browse to the ‘Applications’ folder
  3. Hold the Option key and click the LightBurn icon, or two-finger tap the icon
  4. Choose ‘Open’ from the menu
  5. When MacOS asks if it should open the program, say yes, and it will be listed as an exception in your launcher. From now on you can just launch the application normally.

I downloaded Lightburn today and was negatively surprised that a paid app won’t open under the default security settings on the Mac. So much so that I logged into the forum to ask when to expect a signed update?

The update is signed, but Apple of course has moved the goalposts and now requires that they scan all apps for malicious code. The new pop up is not “we don’t recognize the developer”, it’s “we weren’t able to scan this”, and they still present it like it’s the end of the world for the user, which is frustrating.

All of the documentation they have is around using their tools (XCode) to perform this automatically, and we don’t use XCode to build LightBurn, but we’re working through the process to try to figure out how to do this.
