Ultimaker 4.8 installed and runs fine on MacOS 10.11.6, El Capitan, which is the newest version of MacOS that my old 2009 Mac supports.
But Ultimaker 4.9 refuses to run, saying MacOS 10.13 or higher is required. See attached dialog image.
Since 4.9 only consists of bug fixes to 4.8, I don't see why 4.9 shouldn't be able to run on 10.11.6.
Please fix this.
