I created a ticket at smithmicro but thought i'd double down here:
In anime studio pro V10.1.3 (but the problem was there in previous versions too), selecting multiple layers and applying a layer setting to them, as a new feature of V10, causes the program to crash in 90% of cases, as soon as the apply button is clicked. It concerns any layer setting offering this option (from 3d to masking and everything else). Therefore I have never been able to truly enjoy this feature and have been forced modifying my layers one by one up to now. I thought it 's time you should know in the hope that you will fix the issue soon.

Re: Multiple layer setting always crashing on Mac
I doubt it will be fixed soon. I reported it as far back as 2012.
