Hello @srdjan_djurdjevic
You are right that these are two separate issues, and the second one has an answer already.
What you are seeing on the 2015 MacBook Pro is a known bug in 2.71 build 1680 that prevented Roon Server from starting on macOS 12 and 13. Macs on macOS 14 and later were not affected. Your crash report matches it exactly, down to the assertion in the headless manager, so there is nothing wrong with your installation and nothing further you need to test.
We released a hotfix yesterday, Roon 2.71 build 1683, which fixes this specifically. Details are here:
Please download it from
and install it on the 2015 MacBook Pro.
Once Roon Server is running again, please confirm the build number under Settings, then About, and we will pick the original stuttering issue on the M3 back up from where we left it.
