Having trouble installing and running Second Life on your Mac? You're not alone!
Depending on the version of the OS X that your Mac uses, you may encounter an error when attempting to install or start Second Life for the first time after an update. In late 2019, Apple added an additional step for developers working on Mac OS X apps that requires special validation signatures as a new security feature. Any application (like Second Life) which does not have one of these validation signatures will display an error message:
Is Second Life malicious software?
We haven't changed how Second Life works on a Mac, or added any extra software to it, but at this time we're still in the process of updating to Apple's validation system. The official Second Life Viewer is as safe to use on a Mac as it's ever been.
How do I run the Second Life Viewer on my Mac if I'm receiving this error?
The good news is that it's relatively simple to tell your Mac to run Second Life when you receive this error.
- When the error message appears, click Show in Finder; this will open the folder where the Second Life Viewer is installed on your Mac.
- In the new Finder window, Control-Click (right-click) on the viewer (Second Life Viewer.app) and select Open.
- The Second Life Viewer will open and be ready for use.
Using the Control-Click > Open method from within Finder will tell OS X to open the file regardless of the validation error, and you should be able to use the Second Life Viewer without further errors. Updating to a new version of the Second Life Viewer might cause the validation error to appear again, but repeating these steps will allow you to use the Viewer.
For more information on allowing an application to run without Apple's validation check, please see the Apple Support article on how to Safely open apps on your Mac.
Note: You may need to attempt to Control-Click > Open twice. If the first attempt fails, please try again.
We apologize for the inconvenience that these extra steps cause, and are working on a permanent fix to integrate Apple's validation requirements into our viewer. If you have any questions or further problems opening or running Second Life on your Mac, please contact our Support team and we'd be happy to help.
I'm still having trouble. Is there something else I can try?
If the above method does not work for you, you can also visit the System Preferences window to allow your Second Life installation to proceed manually.
