Switching between Nvidia GPUs in new MacBook Pros requires log out

“The MacBook Pro (15-inch, Late 2008) includes a new feature in the Energy Saver system preference pane for adjusting graphics performance,” Apple’s Support Doc #HT3207 explains.

You can select Better battery life or Higher performance:
• Select Better battery life for situations where heavy, graphic-intensive applications are not being used or use of the MagSafe adaptor is limited.
• Select Higher performance if playing games or carrying out other tasks which involve heavy graphics processing.

When choosing a different graphics setting in the Energy Saver system preference pane, you will be required to log out for the new settings to take effect. After choosing Log Out (shown in the message below), you will have an opportunity to save any open documents or other work.

By default, the MacBook Pro (15-inch, Late 2008) uses the Better battery life option.

  1. Apple has offered up an option that’s never been available before and crybabies are whining about the implementation even before they’ve used it. I agree there’s better ways to do this from a user’s standpoint, but it’s also likely that people will seldom make the switch and it won’t be too taxing.

    This is a great forum to offer your suggestions for improvement and demonstrate your insight and intelligence. Don’t spoil it with a senseless bluster and pathetic whining. If you can build a better laptop, go for it. I’ll even buy one. If not, try to be at least civil to those who are trying to build better computers.

  2. Poor, sad little The Great Apple Fanboy Massacre;

    Not like Vista, which is now nearly two years old and STILL doesn’t work correctly with our company’s vPro boxes…

    From HP;

    Some functionality of this technology, such as Intel Active management technology and Intel Virtualization technology, requires additional 3rd party software in order to run. Availability of future “virtual appliances” applications for Intel vPro technology is dependant on 3rd party software providers. Compatibility of this generation of Intel vPro technology-based hardware with future “virtual appliances” and Microsoft Windows Vista operating system is yet to be determined.

    “yet to be determined” is as good a euphemism as I’ve heard for “It doesn’t work” to date!

  3. @ Reality Check re:

    “C’mon Apple, get this right. When the power cord is connected it should automatically go to the more powerful GPU. Leave it up to the user to change to the lower power GPU when on battery power alone.”

    I gather you know how to accomplish it right now? Perhaps you should apply to Apple for a job. Or at least sell them your technical expertise.
