Downloading the latest kdenlive version on a MacBook with MacOS 11.7.10, it fails at startup with a huge stack trace, the main error being:
“Symbol not found: _kIOMainPortDefault”
I guess this is because macOS11is too old as kIOMainPortDefault was introduced in macOS12: (link rejected)
Probably as a replacement of the now deprecated kIOMasterPortDefault (link rejected)
However the download page suggests the version should work on MacOS 11:
“Requires macOS 11 (Big Sur) or newer.”
I tried installing the older version (Qt5) and it fails too because “Apple cannot check it for malicious software” (which I suppose actually means it’s not compatible with MacOS 11?)
