Jeremy,

<div class="">I think you are seeing two different problems. The 2015 iMac should not have any problem with Alice 3. (Are you using Alice 3?) I currently use a 2014 MacBook Pro for Alice 3 all the time. There are occasional crashes but nothing that severe.
I guess there must be something wrong with the installation.</div>
<div class=""><br class="">
</div>
<div class="">I don’t know about the 2010 MacBook Air. I don’t have any Macs that old to try. I had a 2012 MacBook Air a long time ago. I wasn’t using Alice 3 in those days in class, but I’m sure I tried it out at some point with that computer and didn’t see
any problems.</div>

Hi Alice 3D instructors,<br class="">
<br class="">
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 class="">
<br class="">
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 class="">
<br class="">
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 class="">
<br class="">
Thanks!<br class="">
<br class="">
Jeremy<br class="">
