Thanks for your help guys. I guess I've always been reluctant to change things that seem to work OK unless there is some real benefit and I can't see much benefit in changing to Snow Leopard (at present) and giving myself some potential problems with printing using the 3800 or profiling with the ColorMunki. But ... I suppose I will have to take the plunge sometime.
Since Apple (or whoever, whatever) screwed up monitor hardware calibration 10.5.6, I've reverted to 10.5.5. I now therefore have a G5 running 10.5.5, printing to an Epson 3800 from PSCS3, fed by Aperture 2. This works fine, beautifully in fact. Net result:
- i 'm not going to buy a Mac Pro (Apple loses revenue)
- i'm not going to buy Aperture 3, since it needs Intel (Apple loses revenue)
- i'm not going to upgrade from PSCS3 (and until now I always upgraded, since 2.0) (Adobe loses revenue)
- no incentive to upgrade my printer (Epson loses revenue)
All 3 can let me know when they've sorted it out. Until then ... whatEVER.
(Actually, unless Apple readjusts focus a bit away from consumer gadgetry, I can even envisage moving to Windows, where, remarkably, there's less of this nonsense these days)
