Thank you for helping beta test the SpiderOak ONE application on Apple Silicon Macs. As a reminder, this is only for Mac computers with an M series chip. (Not sure if that's you? Read this.)
You can download the installer here. After downloading, unzip and you'll have a .pkg file to install with.
This is a beta version. Right now, the system Gatekeeper will throw an error like this one when you try to run the installer.
To work around it, please go to Settings -> Privacy and Security, scroll to the bottom of the menu, and press the Open Anyway button next to the warning.
This will allow the installer to launch and installation to complete.
