Leopard ...

Well ... Catalyst works...

On the surface - there are no visual glitches ( apple fixed bugs i reported several months ago )

Since then i haven't seen any specific Leopard problems-

But as usual beneath the surface there are an awful lot of changes in the OS that might affect what we do-

So I have to urge great caution.

But as anyone buying a new mac knows - from Oct 26th - they wont have any choice in the matter.

Performance? I dont know - a little slower than 10.4.x - though not much.

Developers only got access to the release builds yesterday. The same day are everyone else - which is crazy...
So there isnt much time to have tested anything...

The new enhancements do look interesting, especially Core Animation.
It seems that Leopard has media server technology built right into the API... And a pretty formidable one to boot.

Which leads me to ask: Does Catalyst handle Quartz Composer compositions within a QT file?

Catalyst has been able to run Quartz Composer movies for some time now - have a look through the posts on the forum.

with regards to Core Animation - see the thread http://chaldee1.gotadsl.co.uk/~richa...core+animation

quartz composer and 'core animation' sounds fine in theory- but in practise they are performance hogs whichever way you look at them.

fine on 1 layer not much use on more than that.

catalyst has to be optimised for playback on many layers.

Leopard it's very buggy it self , I had it for few days now , probably catalyst application it's ok , but there are too many things going underwood and many are buggy .

To be honest I'm a Big Apple Fan , but I'll not use ( YET 30-10.08 ) the New Os in real Show .

I don't want to panic anyone , but I think the leo it's on "quarantine"

once you buy a new mac now you wont have a choice...

can always disk image it back to tiger...

ive had some BAD issues running an update on a test system - with just the OS - not even tested catalyst yet. Id reccomend a clean new install if anyone is going to update an old system...

beware

Yeah Clean install it's better the update from tiger . I confirm , and I can tell you that if you start from clean install things are not that bad .

I dont think i ever tried upgrading tiger when testing leopard- the developer builds didnt allow this-

But - the system migration assistant seemed to do most of the right things... in preserving settings and such.

Catalyst does work in leopard - and i havent seen any bugs yet.
I have no idea about performance of drivers, etc.

it is unlikely that any new macs will downgrade to tiger.
typically apple prevents this.

new macbook pros - have an exclusive version of the operating system for now- that only works on them...

This scares me. Apple has always tried really hard to release "working" items. The fact that there is a different version for the Macbook Pro indicates to me that there are hardware and driver conflicts with Leo.

I will be interested in seeing feedback from Cat users to see if Leo is causing capture card, video card, or scsi hangups.

It would be nice if Apple just released a scaled down version (sort of like XPe) which gets rid of the crap we don't need.

My suggestion for anyone listening is to create a hard disk with just Catalyst installed on top of Tiger. Then if you decide to use Leo you can have it on a separate partition that doesn't compromise your shows.

I do this anyway since I use my Cat machines as render clusters in post anyway.

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.

Looks like Simon has the right idea. What he did is exactly what anyone else with Leopard should do.

Careful with Leopard and x1900, they don´t go along well. My system started freezing from out of nowhere. Took some time to figure out why, as I´d put in some more RAM etc. But hopefully the machine is cured with clean fans and a clean 10.4... :)

10.5.1
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.

leopard has terrible performance- 10.5.1 is a dog.

only use if you have to. otherwise steer clear for now.

there really is nothing at all worth upgrading for.

some x1900 have heat issues- they have been half documented-
i had a demo machine from apple at LDI trade show which had screen corruption.
I managed to switch to tiger- and problem remained. so its not OS related.

x1900 is a good video card- the 7300 is really lame.

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.

One theory I came across was that Leo generally uses the GPU more than Tiger, so that it will become hotter. I can only speak for myself, but my x1900 worked like a charm for a year with Tiger, and crashed repeatedly with Leopard. Every morning the machine would have frozen from just being idle. And Quartz Composer gave me hourly freezes when running a bit hard.

its not nice to go from rather stable 10.4.11 to the instability and poor performance of 10.5.1-

drives me crazy - every couple of years - the entire system gets broken - and we have to start from scratch-
its nonsense.

i get the feeling there are significant numbers of bugs not resolved in 10.5

for me though the main problem is terrible performance -
