Kako mene to muči od izlaska tog apdejta, naišao na jednom forumu na to:Okay, last week my screen freezes have become literally unbearable (that is as in about six times per day). I then happened to activate the guest account in order to get at least some urgent things done uninterruptedly. Well, and guess what, no crash while working as a "guest".

That made me wonder whether there could maybe be a single setting within my default user account that is causing the crashes. So in the end, I decided to bite the bullet, backed up my personal data to an external HDD and completely erased my user account.

I then created a blank one - making certain NOT to copy over any of the old preference files (I had to be pretty careful with that as I am syncing via MobileMe) - and in the end putting my data back in all the right places.

Anyway, to cut a long story short, I have been working with this new old user account of mine for about a week now and did not experience a single crash ... and that's without making any changes to the system underneath.

At least in my case, the cause for the screen freezes I experienced every since 10.6.3 seems to have been some sort of corrupt file within my preferences, cache files or whatever. Looking back, it was definitely worth going through the entire process of rebuilding my user from scratch.

Maybe this is an option for some of you, too?!
Meni od kad sam tako napravio, još se nije zamrznuo. Pa možda još nekome može pomoći. Kako sam s engleskim dosta tanak, može i mišljenje ili komentar.
Bok !

Jedna od prvih stvari koje ćeš dobiti kao savjet u slučaju problematičnog updatea sistema je da kreiraš novog korisnika i usporediš ponašanje računala na novom i starom korisniku.
Svatko od nas koristi računalo na sebi svojstven način: instalira, piše/briše fajlove, ugrađuje i nadograđuje kako mu paše.
Zato nekima, kod nekih updatea, računalo malo zagrca. Ne mora biti nešto veliko, dosta je neka sitnica da uzrokuje problem, kao što si ti imao.

Zato, uvijek imaj još jedan korisnički račun, pa kad se pojavi problem, vidi kako stvar radi na drugom korisničkom računu.

@ josko... hvala na poduci, vidjet ću jesam li pogodio zrno, ko ćorava koka. Samo, kad idem u preferense na account, uvijek je admin u plavom, a guest ili drugi moram kliknut na lokot i uključit. Tj kako znam s kojim radim ? Da i ispod drugog piša admin kao i kod prvog. Tu sam u vukoj....i pa nemam s kime razmijenjivat iskustva, ili učit. Uglavnom, ako se više neće zamrzavat, ja na konju.
