im guessing this is a developer apple macos version causing it to crash as the latest version possibly changes dropdown stuff but it crashes so much and its getting on my nerves!!!!!!

I believe this has already been addressed ... next version testflight nightly.

is their any fixes in place atm or any dev versions i can use for macos?

You would need to be on testflight for mac or sometimes they build in the nightly here https://github.com/xLightsSequencer/xLights/releases
A new version will be next week at earliest..
