You can verify the Unity AcceleratorThe Unity Accelerator is an external tool that provides an asset cache that keeps copies of a team’s imported assets. The goal of the Accelerator is to speed up teamwork and reduce iteration time by coordinating asset sharing so that you don’t need to reimport portions of your project. More info
See in Glossary version from a client machine accessing a remote Unity Accelerator instance and also from the server machine.
From the client, access the API agent health end point by visiting the following page from a browser: http://[AcceleratorIP]:[AcceleratorPort]/api/agent-health
Alternatively, examine the unity-accelerator.log file in the log folder of the Accelerators configuration directory. The sysinfo message displays the currently loaded Unity Accelerator version:
{"level":"info","ts":"2025-03-05T11:10:52.144Z","msg":"sysinfo","agent_id":"john.smith_id","agent_name":"john.smith","component":"agent","pid":91985,"agentversion":"v1.0.941+g6b39b61","goversion":"go1.15.4","os":"darwin","arch":"amd64","compiler":"gc","maxprocs":10,"numcpu":10}
The data is arranged in key-value pairs, and the agentversion key displays the current version "agentversion":"v1.0.941+g6b39b61"
From the Accelerator server you can use the Unity Accelerator application to report the version with unity-accelerator --version, or unity-accelerator.exe --version on Windows
On Windows, the Unity Accelerator application is usually installed under C:\Program Files\Unity\accelerator, and on macOS it is usually installed under /Applications/Unity/accelerator unless a different location was specified during install.
For Unity Accelerator installations on Linux systems, all Linux executables have signature files that you can verify to ensure that no malicious entities have tampered with your downloaded Unity Accelerator version.
You can verify the signature files with a trusted version of GnuPG.
Download and import the Unity Accelerator public key that signs the Linux installer files:
$ wget -qO- https://download-accelerator.unity3d.com/unity-accelerator-pub.asc | gpg --import -
You only need to import the key once.
Check the fingerprint of the imported key:
gpg --fingerprint sst-ops@unity3d.com
You should see:
pub rsa4096 2019-12-02 [SC]
9BC4 B04D F2E8 74E5 64AA 47E7 6D44 3B8B 002C F61F
uid [ unknown] Unity Technologies ApS (Accelerator signing key) <sst-ops@unity3d.com>
If the fingerprint matches, the key is authentic and trustable. For more information about marking a key trustable, refer to https://www.gnupg.org/gph/en/manual/x334.html.
To check the version of Unity Accelerator that you installed is original and unmodified, verify the file’s signature. It’s available in the downloads page.
Then run the following command:
gpg --verify unity-accelerator-v1.5.63+g9672c1c8-linux-x64-installer.run.sig unity-accelerator-v1.5.63+g9672c1c8-linux-x64-installer.run
If everything is correct, you will see:
gpg: Good signature from "Unity Technologies ApS (Accelerator signing key) <sst-ops@unity3d.com>"
This confirms the installer is genuine and unmodified.
You may also see a message like:
WARNING: This key is not certified with a trusted signature!
There is no indication that the signature belongs to the owner.
This does not indicate a problem with the signature.
It means that you have imported the Unity Accelerator public key, but you have not personally marked it as “trusted” in your keyring.
This is normal for public distribution. As long as you see:
Good signature from "Unity Technologies ApS (Accelerator signing key) <sst-ops@unity3d.com>"
the file is verified correctly.
