MS office, remote desktop and Toast cannot be open suddenly, if it is cause by virus, does one can recommend any anti virus software for mac

[TETENAL]

It's not caused by a virus.

Open the program "Console" from Applications->Utilities, try to launch one of those apps and then tell us what the console says.

[Nivag]

When you say they don't open, what happens?

Which OS are you running and what version are the Apps?

Have you installed/updated anything lately?

I doubt it's a virus, as far as I know there aren't any in the wild, yet....

[Gee4orce]

Likely a corrupted font.

[isomet]

just checked and it seems all powerpc application on my intel macbook doesn't work, what have missing suddenly?

[TETENAL]

Did you run Monolingual?

[Sherman Homan]

If your Intel native programs are running and your PowerPC programs are not, then you have a problem with Rosetta. Rosetta runs "behind the scenes" to allow PPC programs to run on your MacBook. Reinstall the system (Archive & Install), do the updates and all will be well. As TETENAL alludes, do not do a custom install that eliminates language support.

[Visualize]

You can try and use an app like OnyX to Optimize the system. It's also called prebinding. Do a full Optimization and reboot the computer. I don't know if it will work but I heard that the latest QuickTime will break PPC programs under some circumstances. And the fix is to Optimize the system also called prebinding.

But if you have used that dreadful app called Monolingual to remove PPC code, then ... reinstall OS X.

[isomet]

Dear everyone, could you tell me how specifically I can reinstall the system, where i can find the application to optimize the system. I have never heard fo monoligual and don't found anything related in spotlight

[TETENAL]

If you didn't run Monolingual, then maybe the QuickTime issue causes your problems.

MacNN | Apple to investigate QuickTime 7.2 flaw

To reinstall the system follow these instructions:

Mac OS X: About the Archive and Install feature

[isomet]

Hi teltenal, i just can't find my apple disc, anywhere i can make the download , it seems to taught me to reinstall the whole os and any shortcut by just run the archive and install feature

[Rorzabal]

Before you perform a reinstall, I recommend you try following these instructions from Apple:

Mac OS X: Some applications may not open after QuickTime 7.2 Update

[isomet]

I did try, still not working, following is the command msg
felixs-computer:~ Felix$ sudo update_prebinding -root / -force
Password:
update_prebinding: error 11 running update_prebinding_core

[kennedy]

Thanks for this info.

I have to ask....

WTF does Apple still have that QT 7.2 update up for unsuspecting people to trash their systems?!?

[brentm]

Most of the systems I've seen with this problem are fixed with the 10.4.10 combo update. However I have one that gives the

error 11 running update_prebinding_core

error. I've since installed the QT 7.3.2 update as well as all other current updates with no success. Any other suggestions?
