I don't understand why this patch (from Jasch) works fine on my macbook pro and doesn't display anything on an iMac i5 ....

The pwindow remains empty. Exactly same patch.

iMac is :
 Model Name:	iMac
  Model Identifier:	iMac12,2
  Processor Name:	Intel Core i5
  Processor Speed:	3.1 GHz

Well i just updated to 6.0.7 on the iMac, full of hope ... Doesn't change anything.

Update : the same patch on the same iMacs work in Max5.

Search paths? Are there any error messages in the Max window?

I opened your patch. It seems that it's using a couple of third-party externals, namely, 

. Are you sure that you installed these externals on your iMac as well?

I opened your patch. It seems that it's using a couple of third-party externals, namely, [attrui] and [jit.grab]. Are you sure that you installed these externals on your iMac as well?

[attrui] and [jit.grab] are standard objects in max 6. So if you are opening both patches with 6 that should not be the problem. Best to look at the max window (cmd+m) and see if there are any errors coming up.

No errors in the Max window John ... It really looks like a bug :

it works on the iMac 12.2 i5 with a Max 5.1.8

Ok on both versions on my Macbook Pro dualcore

(actually i suppose it would rather have something to do with openGL rather than processors ...) ?

I looked at the patch and the jit.window didn't display anything on my machine until I plugged the outlet of the jit.matrix below it into it's input.

This worked but after about 2min my machine became unresponsive and I had to do a hard shut down.

Sounds like it might be a bug, I had a jitter patch that produced very different results on different machines.

Josh was quick to diagnose and fix the problem.
