I, i had the exact same problem with Emote and the update to 1.2.4

I tried both on OSX and PC, tried wireless or cabled options and even a virtual Win10 through parallels.

All option lead to the same crash of Emote after downloading the update (Progresss bar finishes, then it diapperears)

I sent all bug reports to Apple, but i can also send one in here if you like.

But in the end i updated the H9000 from the hardware unit itself and it worked right away.

So, until this is fixed, i suggest you just use the front panel interface ( H9000R not 🙁 ) and innitiate the update there.

Also, why a new Emote can not update and older H9000 is beyond me.

That should be changed…for real
