Leopard ...

[samsc]

Have been running catalyst on a 2.6G 8Core Mac Pro, supplied pre-installed with Leopard. All functionality seems to be fine.

However the most up to date version of quicktime didn't seem to include apple intermediate codec. Tried the web installer - but eventually had to find the 'apple intermediate.control' file and copy it from my laptop to the mac pro... - then it worked.

Also disabled: time machine, dashboard, mouse zooming, expose, and desktop views, put all drives in to privacy too.

This Mac was awaiting its proper ATIX1900XT card and was still running on a NVIDIA7300 - the graphics bargraph in catalyst was high and I would expect this to drop significantly with a replacement card.

So good news for leopard so far - but I don't think theres a great need to rush out and upgrade your tiger system - and no need to downgrade your new leopard system.

functionality - yes fine-
but leopard has terrible performance on the machines i tested.
dual g5 , intel mac pro 2007.

not recommended at all.
do not upgrade, only use if you have a new machine which doesnt have an option.

its 50%-100% slower in number of layers than tiger - on exact same hardware-
not dependant on codec or rendering, all movies are much slower.

We got a Mac Pro 2.66 with Leo the week before the newest ones were released, but it worked fine to install a clean Tiger from an older Mac Pro installer I had.
