When using the fast user switching feature of Mac OS X 10.4.x (x == 1 to 8 at least) there is a nasty bug which screws up the color profile settings (if you use a custom color profile, which is very likely if you use a LCD screen).
The bug appears like this:
- you log in: color profile OK
- you switch to another user: color profile OK
- you switch back to the original user: color profile screwed up and can not be reset by the obvious means in the system settings
I found a workaround here which works pretty well:

Thanks a lot for sharing this!
In short:
- to fix the problem temporarily (e.g. fix the color profile) start
/System/Library/Frameworks/ApplicationServices.framework/Versions/
A/Frameworks/CoreGraphics.framework/Versions/A/Resources/DMProxy
- to fix it permanently add this to the startup objects for all users
Have a colorful day!

Flash player screwed up on Mac OS X
Today I tried to watch youtube.com on my Mac Mini running Mac OS X Tiger 1.4.8 but I was hearing no sound. The video is played using some flash plugin (which sucks). The sound setting on my machine seemed ok since all other apps were playing sound fine.
Google found some hints here:

But none of the hints would solve my problem exactly. The key seems to be the Audio MIDI Setting application. Open a shell and type:
Twiddling with the volumes at the bottom of the first pane and setting the output device correctly solved the problem for me. Others reported that they needed to (re-) set the sampling rate to 44100.
This is of course only a workaround. This Flash stuff is real crap as always. You always need the newest version to be able to do stuff you could easily do without it. And it prevents you from doing useful stuff which you could do without it, all for commercial reasons. It does not play fullsreen fluently on my 1.25 GHz iBook while this plays DVD with much higher bitrate and framerate fine, i.e. it does not use the hardware scaler. This crap sucks.
By the way: This is exactly the type of behavior I expect from Windows machines: Install something and something completely unrelated breaks. Apple: Please make this more robust!
So long ... happy youtubing! :-)
