macOS Mojave is due to be released in the near future. We've been testing with various beta releases of Mojave across multiple Mac systems - we will update this article after the full release version of Mojave is made available for us to test with compatibility information for our current products.
Please check that all other software/hardware you use to make music is also compatible before updating and never update your operating system during the middle of a time-critical project.
Based on past experience we would generally advise waiting for a few months after the release of any new operating system before updating in case there are any initial issues which need to be patched.
If you receive an error message stating 'System Extension Blocked' after installing Focusrite software/drivers then please see this article.
