<br>
Does anyone here use Apple computers with Alice? I’ve seen crashes happen when certain objects are added - especially when “too many” items are in a scene.<br>
<br>
I can’t quite pen down why it happens. I know a student with a 2010 MacBook Air had to limit the scene to about 3 items otherwise a 4th one would get the “Queen of Hearts Exception”. A student with a 2015 iMac would crash if any bi-pedal object was added. <br>
<br>
My guess is that there is a specific memory limit esp on Apple computers for Alice. The only requirement on Alice’s page is a 1GB ram video card. A 2010 MacBook Air only had 256MB of Video memory, so maybe that’s why?<br>
<br>
Thanks!<br>
<br>
Jeremy<br>
