Yep - exact same issue - got it for xmas - though I guess I was lucky since I had no other unboxing issues whatsoever - actually a complete/finished product out of the box - but when used with a mac and os 10.11.anything it crashes if usb plugged in - also - even with a windows machine with windows 8 or running parallels windows virtual machine and windows 8.1, the scanning software NEVER works - I get a scan but when I go to save the scan or finish the scan in any way past the actual multiple scans or erasing any defects etc, it crashes -- I've even skipped everything past the initial crappy scan and it still crashes - just won't save the point cloud.
I've actually moved past using the xyzware software and have used other free things out there but have decided to pay and get simply3d and it is AWESOME!!! simple to install and does EVERYTHING -- but now I am looking at a substitute for the scanning piece of things - If I am able to replace the scanning software side of things, I will be SET!
So if anyone knows of any replacement/substitute scanning software to drive the scanning portion of the AiO PLEASE let me know -- All we can hope is that XYZ gets their act together and updates the software for all of us that invested in their machine and have been willing to give them their extra profit on the cartridges etc as a subsidy on the inexpensive but 'finished' hardware -- but they need to invest in the software portion of things so it just works - nothing fancy - but just works!
If someone writes a scanning software -- or better yet, gets simply3d to add a scanning add-on -- I think lots of people would be willing to pay for it -- I know I would as then my AiO becomes a GREAT little machine for the price!
