Capella 7.0 can't be launched on my MacBook Pro

Hi all,

I have just installed Capella 7.0.0 on my MacBook Pro. It has an M2 chip, so it’s an ARM system. My macOS version is Sequoia 15.0.1 (24A348). I downloaded the “aarch” version. I can remove the tar.gz compression and get the capella.app executable. But when I launch it, I get an error message reading it is damaged and I should trash it!

Can anyone help on this? Did I miss something in the installation process?

Thank you.

You’ll need to disable the macOS extended attribute for the Capella.app folder.
Run the following command in a console terminal.

sudo xattr -d com.apple.quarantine /path/to/Capella.app

Obviously change the path to whatever location you unzipped the Capella.app to.

Hi woodkse,

Thank you very much! Seems to work fine now.
