Issues with Prusaslicer on Mac with voiceover

Hi,

Long shot, anyone had any experience with the 3D object slicer Prusaslicer on Mac? I've got it on my 2018 MacBook Air and it's either hanging with the dreaded 'busy' report or simply crashing out. Looking at the forums no other users seem to be experiencing this so I can only assume the differential is VoiceOver, but can't for the life of me understand how it could conflict so much as to cause a crash.
