It's fun that you put that up, because I experienced the same problem. I have an iMac with i5 processor and spec way higher than recommended and the screensaver freeze when I go into my screensaver configuration and I select this browser. It's not working. And now I can't download back the file since I closed my Mac and they ask to pay again on the nintendo club when it's written that I paid for the product.

Please someone, help

Ditto. Brand new mac mini with a 4G ram upgrade. Should handle this fine, but it goes all white. From activity  monitor it almost seems like it's a conflict with the flash player. Hard to really pinpoint though since it basically kills everything.

Same exact problem here.  I'm using a brand new Macbook, everything on it is completely up to date.  It's obviously not our problem, the screensaver just doesn't work period on the Mac.  Here's hoping they fix it but I won't get my hopes up.

I have a mid-2010 MacBook Pro that is maxed out and this screensaver doesn't work for me either.  I get the white screens and then have to wait quite a long time to get my system back.  It also locks up System Preferences when trying to access options.

It has to be a Snow Leopard compatibility issue.  Has anybody tried the screensaver on Leopard or Tiger?

I am in the same boat, no clue why I can't get it to work but it just will not work, I am running a i5 iMac 27" Which is more then enough in the specs to get this working.

I'm having the same issue using a 3 month old MacBook Pro running on an i7 with 4GB of RAM.  However, if I switch over to Windows 7 on Bootcamp the screensaver works just fine.  So, the system itself isn't the issue, it just seems to be incompatible with the OS (running Windows and Mac OS on the same system).  Just seems like another PC to Mac compatibility issue.

ROBMC1: Flash isn't the prob because I have flash 10 installed and its still not working properly.

I just downloaded the SMG2 screensaver for Mac on my 27" iMac. I don't have a freezing issue, it's just REALLY slow loading/playing it (it's like a slide show maybe 1-2 frames every five seconds). When I go to the screensaver panel and let it load/play the preview, it seems to be fine but when it kicks in the screensaver full screen... slideshow time. Not too pleased right now.

I have a solution but it isn't trivial.  If you are afraid of the guts of your system turn back now.

For those of you still here:

The screentime screensaver creator this is based on doesn't work well with Snow Leopard 64 bit.  But you can run the screensaver in 32bit mode which will allow you to run it without any issues.

Step 1: This will rename your screensaver application from Apple. Open terminal and type:

cd /System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/ScreenSaverEngine.app/Contents/MacOS/

sudo mv ScreenSaverEngine ScreenSaverEngine-orig

Step 2: You need to execute the screensaver using arch -i386 to tell it to run in 32bit mode.  This script does that:

In terminal type:

sudo nano ScreenSaverEngine

Put the following text in the text window:

Press ctrl+x and when prompted type Y to save the new file.

Step 3: Change permissions on the new file you created so it will run for all users:

sudo chmod 755 ScreenSaverEngine

Thats it, it should now just magically work.

You can also run the preferences panel in 32bit mode which will let you select and test this screensaver.

I'll add my two cents also. I'm running a MacBook, Snow Leopard (10.6.4), plenty of memory and hard drive space for the specs of the screen saver, and I get the same issues as others who have posted here. I ran Disk Utility to verify the hard drive, and it tells me that my hard drive is corrupt and I need to boot from the original disk. Has this screen saver really screwed up my entire computer???

You might have to re-download it or call nintendo about your problem.

I'm another mac user that this doesn't work for.  I'm running Snow Leopard on a 2009 macbook pro.  I've purchased both the Super Mario Galaxy 2 screensaver and the history of Mario one.  Both play fine in the preview screen, but go white when activated.  I have to push the volume up/down or the screen dim/brighten buttons on my comp in order to exit the white screen.  Nintendo really needs to solve this problem.  Especially since it's affecting so many people.

I would sure love to see Nintendo acknowledge this problem and offer us a fix.  I've had this screensaver for a while now and have yet to get it to run on a Mac that's only about 6 months old.

I would assume now that the Dragon Quest IX screensaver has the same problem on Mac. I wish someone would see these posts and do something about it, I'm still patiently waiting.

Yes me too i just downloaded it today! This is bad

Hey guys, I recently upgraded my mac OS X to LION and the screensaver appears to be working fine now
