I also have a color problem when Save For Web

Question

Using Photoshop CS4 and I also have a problem when I use the "Save for Web & Devices" My colors also get bleached. I found a thread with the same problem but on Windows.
As I have a Macbook Pro I can not change my monitor settings. In the SFW I check "Convert to sRGB" but it make no difference. I also tried to convert in the menu before using SFW. So I need some help here.
Here is a screen shot on my screen: http://www.scancyp.com/dump.jpg

Also I was wondering why?
You need to calibrate and profile your monitor regularly and often
First:  Because monitors can and do drift.  In CRTs all kinds of electronic components and the phosphors themselves age; in LEDs and LCDs the back-light illuminants do; etc.
Second:  Monitor profile files can and occasionally do get corrupted.
I validate the calibration of my monitors practically on a daily basis.
If you don't have an accurately profiled monitor at all times, your work is wasted.

But it's a whole science to calibrate the monitor without a hardware calibration kit. I had a look at SuperCal as you suggested, but I am afraid it's gona be too complicated for me as I think it's hard enough to calibrate with the Apple calibration tool.
Even the cheapest hardware calibrator puck will give you superior results than any eyeball calibrator.  That said, SuperCal is a tad better than Apple's  built-in eyeball calibrator, though nowhere as good as a hardware calibrators.
Personally, I detest laptop screens and categorically do not consider a MacBook Pro a suitable machine for serious color work.  For this reason, I cannot in good conscience insist on your buying a hardware calibrator.
Laptop screens can be nearly impossible to calibrate accurately.

I have made a new screen shot with my results so far. Upper left is Photoshop original. To the right the SFW and lower left the preview result. The SFW result still don't give me the colors I want, but as I said: closer then before.
Screen shots from an uncalibrated or inaccurately calibrated monitor are worthless, always.  They do not help at all, especially when they are partial snippets that don't show the whole picture.
This time around they are even worse, as I cannot see whether you rectified your Preview setting in the Save For web dialog box to "Use Document Profile", as I told you earlier:
You have to start by changing that setting in the Save For Web dialog box to "Use Document Profile".
Is your original document in a device independent color space (i.e. was your working colorspace set to such a device-independent color space like Adobe RGB or sRGB when you created the original) and is it properly tagged (does it have such a device independent profile embedded)?  If the answer to any of that is no, all your work is wasted.
If your working space is set to your Monitor Profile, then your work is a useless mess.  If the original is in your Monitor Profile, it's no good either.  Same goes for the Preview setting in the Save For Web dialog box, if it's set to Monitor Profile, it's useless.
If you view any untagged image (any image without a device-independent profile embedded) in any Apple application, be aware that any such Apple application, From the Finder, through Preview, Aperture and iPhoto to Safari, will throw your monitor profile at your image (assuming it's really in your Monitor Profile) and it will display your image in the wrong colors, as all Apple applications stupidly assume that all untagged images were created by some fool who didn't know better.

But now my main questions is:
Why the Original in the Photoshop SFW don't look like the original? And then why the Optimized in the SFW also don't look like the the preview? (Specially look at he shadows of the palm tree that shows in the Optimized but not in the preview)
I have no idea what all your other color settings throughout the whole application and in the Save For Web box are, what else may be messed up on your machine, or how badly inaccurate your monitor profile is.  Again, your  screenshot is not helpful and never will be—unless you had an accurately profiled monitor, which you will never be sure you have on your laptop, ever.

And again, should I invest in SuperCal? It seems also to be very old.
SuperCal is better than Apple's calibrator, regardless of whatever its age may be at this point.  Last time I checked, SuperCal was free.  If they want to charge for it now, don't buy it.  It's not worth it for a laptop screen.
On a side note, if you think SuperCal is "too complicated" for you, I doubt you're ready for Photoshop anyway, even with a better machine.  Sorry, no offense meant, but it wouldn't be fair to you if I didn't tell you exactly how I feel.
