after the first installation of ableton live 8.0.1 on my macbook white series, the audio stream started to go even worst: first the system started to lag and then shut down the audio while working with live8 (i had everytime to plug in again my presonus firebox or to reboot), after it started to do to the same error everytime while using the soundcard with vlc, for example. something very strange happened also: my macbook started to lag and freeze heavely (more than with live and with some kernel panics also) during youtube HD movies playback.
i tried to plug the firebox in macbook pro (now old series) and it didnt get any connection so, thinking about a audio interface problem, i've buy a RME Fireface 400: many people said that it's an high quality board, thanks also to the drivers that never miss. i tried it with live 8.0.3: worst than ever. same lag as the firebox without the final shut up, but with a not so nice "BEEP" (very very loud guys).
i tried to connect a friend's fireface 800: i had kernel panik at the system start of leopard (worst to worst

)
all of this has been tried with 8.0.1, 8.0.2, 8.0.3, 8.0.4b, and with 10.5 10.5.6 10.5.7 (many forums said that 10.5.7 has got core audio bugs)
i have to notive that my equipment has been compromised: i've use live 7.0.1 as long as live 8.0.1 has been release without any error, always fine job. after a month of live 8.0.1 ---> lag, audio crackle, NEW AUDIOBOARD (€870), system check, presonuns support, apple center, ableton support, new swears ( u, users, u know how it is when it's like that, u know), no solution has been find and i cant use a firewire board without having the troubles said first. i've close my macbook and i've buy a new macbook pro 13" BUT im VERY VERY VERY afraid to install live on my new mac. i think that this company should test BETTER this software first than SELL to us. maybe my case is very rare, but it costed me something like €1800, and they very are rare also.
my computer always worked fine first than live 8: i loved live 7 and also live 8 during the little time i reached to use it, and i would like to use it again, but i think that im gonna switch to logic pro.
im not asking for a refund, of course (i dont try neither), it's just to inform other users what COULD HAPPEN with this software that is absolutely NOT STABLE, as a lot of users in this forum and that i know say.
we buy your software. we use it cause it's the best for music creation but be careful with releases. we pay them.
