Mac OS X 10.6.3 has worked out fairly well and my living room carpet has yet to spontaneously catch fire as a result of installing it, but an ongoing issue with the operating system version seems to corrupt graphics on external displays when you present in full screen with “mirrored” displays. In routine situations, the display will work and show the mirrored desktop in the Finder, but when applications take over use the display to show full-screen presentations, media, or other purposes, the graphics will garble and can only be fixed with a restart.

Per CNET, this problem seems to happen on multiple machines, though MacBooks are more prominently affected. This is probably because they are used more for presentations. Users have tried SMC resets, PRAM resets, and numerous approaches to clearing caches, fixing permissions, running other maintenance routines with no luck.

Over on the Apple Discussion Board, chatter between a number of has indicated that the problem could be a bug in the latest OS release, which updated the drivers, OpenGL, and other graphics technologies.

If you are affected by this problem, you can use one of the following work-arounds to keep your display from corrupting:

Try a different video processor:
For MacBook Pro owners who have multiple GPUs in their systems, the problem may be avoidable by switching the graphics processor being used. To do this, go to the “Energy Saver” system preferences and change the option from “Higher Performance” to “Better Battery Life” or vice versa.

Use extended desktop:
Instead of using the mirroring mode in OS X, change the external display to be in extended desktop mode. Do this by going to the “Displays” system preferences and unchecking the box to “mirror displays.” Once this has been done, to use your presentation, just drag the window to the desired display and activate it (should work in PowerPoint and Keynote).

Make a presentation boot drive:
Make a presentation boot drive if you have an external drive. Install OS X to it and upgrade it to 10.6.2, and install your presentation software to it. Then when you are giving a presentation just copy your presentation to that drive, reboot to it, and run your presentation in mirrored display mode without the display problems.

Move back to 10.6.2:
The last step is to move your system back to OS 10.6.2, which can be done by restoring to a previous Time Machine backup. It can also be done by performing a reinstallation of OS X from the Snow Leopard DVD. The installer will create an “Archive and Install” of the system that should keep as many of your settings and application installations as intact as possible, but do be sure to back up beforehand as an extra precaution.

Rumor has it that Apple has started issuing developer releases of OS 10.6.4 already, so hopefully the update will address these issues.

Sources cite leaked fourth-gen iPhone prototype as close to final product

There could be a reason that Steve Jobs is madder than usual about the leak of the fourth-generation iPhone prototype; it may have been fairly close to the final product.

Citing sources familiar with Apple’s fourth-generation iPhone, Daring Fireball revealed that the barcode affixed to the prototype device obtained by Gizmodo, which read “N90_DVT-GE4X_0493,” gives insight into how far along Apple is in the design of its next-generation phone.

“‘N90′ is Apple’s codename for the fourth-generation GSM iPhone, slated for release this June or July,” Daring Fireball’s John Gruber wrote. “‘DVT’ stands for ‘design verification test,’ an Apple production milestone. The DVT milestone is very late in the game; based on this, I now believe that this unit very closely, if not exactly, resembles what Apple plans to release.”

Gruber went on to say that although Apple is extremely secretive about unreleased products, it simply must let the units be used off of its Cupertino, Calif., campus to be tested. Apple reportedly distributes dozens of near-final units for field testing months in advance. Gruber said this practice is even more widespread with the iPhone than other Apple-developed products, because of the extensive nature of cellular network testing.

“The same was true for the 3GS a year ago, and the 3G the year before that,” he wrote. “The original iPhone was announced six months before it went on sale; in the interim between the January announcement and its debut in stores at the end of June, limited numbers of them were used for field testing.”

Even Apple co-founder Steve Jobs himself was spotted with an iPhone in public before the device was formally released to the masses.

The fact that the next-generation prototype iPhone was smaller and more compact than the current iPhone 3GS handset gave Apple the ability to wrap the prototype with an outer casing that made it appear to look like a current-generation device. The person who allegedly found the handset at a bar didn’t realize it was wrapped in a case until the next day.

The design of the iPhone has been largely unchanged from when it was first introduced in 2007, but the lost prototype and its near-final state would suggest Apple intends to modify the look of its handset. The discovered device abandons the curves of the previous-generation models, instead adopting a flat back made of new material to improve reception. It also sported a more angular look with an aluminum border. The prototype also replaced the volume rocker with two separate buttons.

Even greater changes were found inside the device, where Gizmodo discovered shrunken components to accommodate a battery that was 19% larger than the current-generation model’s power supply. The logic board in particular was drastically reduced in size, just one-third the size of the current model.

Stay tuned for additional details as they become available and let us know what’s on your mind in the comments.
