Currently Being ModeratedMay 18, 2009 5:25 PM (in response to davidovitch)It sounds to me that something is causing a reset when the MacBook is attempting to shut down. You should check your system, console, and panic logs to see if anything is entered related to same. You can check these logs using either the Console application or with the System Profiler utility (both are in /Applications/Utilities).
I'd also try starting in the so-called "safe mode" to see if the problem happens there. If it does _not_ then you most likely have a software issue and not bad hardware. Here is an Apple Support article on safe mode.

I tried starting up in safe mode but that didn't change anything (macbook still restarted on shutdown). I also checked the logs you mentioned but I can't really read them (computer-language is not my strongest point).
I'll just take it back to the store. I bought it new so it's supposed to work perfectly; I don't want to have to go through a lot of trouble just to get the machine to function the way it is supposed to (I've done that plenty of times with pc's already ;))Macbook, Mac OS X (10.5.7)

Take it back and get another Mac. Don't mess around and drive yourself crazy. You just unlucky. I got a lemon refub MacBook Pro Unibody that was randomly waking up from sleep and starting back up after shutdown. The fans were also ramping up to 6K RPM for no real reason.
I "downgraded" to the same MacBook you have now. This is a refurb too. It has been perfect.
If you have an Apple Store near you, first call AppleCare on the phone and open a case. Then make an appointment with a Genius at the bar and take it in. Most likely they are going to give you a replacement Mac on the spot.

Somehow the problem seems to have disappeared now. I was going to take it back to the store tomorrow, but today and yesterday the macbook has been shutting down properly, without restarting. I think I have two weeks (by law) to return the device and get my money back or the macbook replaced, no questions asked. So I will probably give it another few days and see how it goes.
BTW When I called apple customer service they hadn't heard of the problem before.

Currently Being ModeratedMay 22, 2009 4:21 AM (in response to davidovitch)If this problem comes and goes you _may_ have defective DRAM (memory). Don't panic yet, it's only one possibility. However, if shutdown fails again immediately after it restarts go into the System Profiler (under /Applications/Utilities) and check the state of your DRAM (left column in System Profiler window -> Hardware -> Memory). The memory status should show "OK."
You may also want to run the hard disk and extended hardware tests.
First, run the verify disk and verify permissions checks using Apple's Disk Utility (located in /Applications/Utilities). If you find any problems make certain that you have backups of any important data and then run the repair options within Disk Utility. Also make certain that the disk's S.M.A.R.T. status is shown as "Verified" (look at lower right side of window in Disk Utility).
If the disk checks okay then you should run Apple's Hardware diagnostics. To do that, shutdown the computer, hold down the "D" key and restart the MacBook (while still holding down on the "D" key). Continue to hold the "D" key down and after a while a window should appear with instructions on how to run the diagnostics (at this time you may, of course, release the "D" key). The extended hardware tests take a good while to run, so you may want to run them after you've finished using the computer for the day (just plug the computer into the power supply and let it run overnight).
You also want to make certain that an external peripheral isn't causing this problem. If the problem occurs again then try disconnecting all of your external peripherals and try the shutdown again (several times to verify working or not).
You could also have a defective Mac OS X system installation. You might be able to eliminate that possibility by booting from your Mac OS X installation DVD (you can use that DVD to boot and shutdown your computer as a test, you don't need to re-install the system software). After you boot into the installer screen (from the DVD) look under the Utilities menu and select the startup disk option, select your internal drive, then select from the menu Startup Disk -> Shut Down). Then when you restart the MacBook hold down on the mouse/trackpad button while the system boots (this should eject the DVD before the system restarts).Mac Pro 2.66GHz 2GB RAM, Mac OS X (10.4.11), MacBook 2.0GHz 2GB SDRAM on Mac OS X 10.5.6
