Any suggestions?

Ed, I don’t have an Intel Mac running Sequoia to test with. I do build successfully on Apple Silicon Macs running Sequoia, following the directions at: https://www.mbari.org/technology/mb-system/installation/ Your build is failing on the TRN component of the software, which is not important for most users. You can skip building the TRN tools by adding --DbuildTRN=OFF to your cmake call: cmake --DbuildTRN=OFF .. We need to update the website build instructions as we’ve worked out a way build MB-System on MacOs Tahoe. The short story is to use Homebrew rather than MacPorts to install the prerequisites. However, MacPorts still needs to be used to install on MacOs Sequoia and prior. I hope this helps.
