[Users] Mac users, any luck displaying numerous seismic attributes?

[Jim Flocks]

Hi,

In response to an earlier post, OpendTect will operate on a 
Intel/Mac, but is limited.  It appears the Intel Mac has a problem 
displaying large or numerous seismic lines.  I cannot display the 
seismic attributes on more than two 2-D seismic lines at a time. 
However, numerous (14+) seismic lines display just fine on a slower 
non-Intel PowerPC, with less RAM.  Unfortunately the PowerPC cannot 
be used to create horizons.  RAM fills and it crashes.

I tried several Mac configurations, details are below.  Just today 
tried a Dual Core with more memory and a faster graphics card, and 
even tested running Windows XP using Parallels, to no avail. I know 
the project is o.k. because it displayed on a Dell PC running windows 
XP (and on the slower PowerBook).

So, for me, doesn't look like I can take full advantage of OpendTect 
yet: either get full display (PowerPC), or the ability to draw 
interpretations 1 line at a time (Intel-Mac).  Has any other Mac 
users had better luck?  Has anyone tried a 2+ GHz, older PowerPC with 
lots of memory running OpendTect 3.0?

Thanks,

Jim


Test details:
450 MHz Power PC G4 (OS 10.3x, OT 2.4) - OpendTect will not operate

1.25 GHz Power PC G4 PowerBook (OS 10.3x, OT 2.4) - will operate 
nicely, cannot create horizons

2-2.6 GHz Dual Core Intel Mac Pro (OS 10.4, OT 3.0) (1GB memory) - 
will operate, can create horizons, but will not display large or 
numerous seismic lines.

Same config as above but with  more memory and faster graphics card:
(2GB memory, ATI Radeon X1900XT, 512MB VRAM) -  will operate, can 
create horizons, but will not display large seismic lines.

Using the above computer running Windows XP on Parallels has the same effect.
