Apple Issues Fix for MacBook Pro Vertical Line Problem

Apple has issued a firmware update for its new 17-inch MacBook Pro which, supposedly, addresses a problem of vertical lines appearing on the display. The problem is apparently being experienced by a portion of owners of Apple’s new 17-inch unibody MacBook Pros: some displays show green vertical lines and other display anomalies when using the integrated Nvidia 9600GT discrete graphics processor.

Apple’s svelte (770K) update appears to fix the problem; however, it is not the first time Apple has had issued with the Nvidia graphics controllers used in its MacBook Pro systems. Some users reported the vertical lines problem only happened when the laptop was running hot; others reported the problem even when the 17-inch system was running cool.

Apple introduced the new unibody 17-inch MacBook Pro in February, rolling out design features from its unibody 15-inch models to the high end of its notebook product line. Among the 17-incher’s controversial features is a new battery technology that claims to offer up to 8 hours of use: however, the battery cannot be removed by the user, making swapping or replacing impossible.

Owners can download the firmware update from Apple directly, or pick it up automatically via Mac OS X’s built-in Software Update feature.

Best Apple deals: Save on AirPods, Apple Watch, iPad, MacBook

Apple has been a big player in the tech space for a long time, and it has pioneered some of the technology we use today, such as best wireless earbuds and the best smartwatches. If that wasn't enough, it even makes some of the best best laptops and best tablets on the market, so pretty much whatever tech you're looking for, Apple has an excellent version of it. Not only that, but Apple's ecosystem is also easily one of the best available, with only Samsung really competing in that space, and if you're already in the Apple ecosystem, then it makes sense to continue buying stuff from Apple.

Of course, Apple tech can be quite pricey, which is why we've gone out and searched through various big retailers to find you some of the best deals we can find. That includes everything from the MacBook to the AirTag, so hopefully, you can find the perfect deal that fits your needs and budget.

How to customize mouse gestures on Mac

Did you know that you can still pull off gestures and haptic tricks with a Mac computer, even without a touchscreen? Such feats are possible, just as long as you own an Apple Magic Mouse. Far more than a sleek-looking desk accessory, the Magic Mouse functions much like a MacBook trackpad. Taps, long presses, swipes, and pinches (among other actions) deliver a number of results, and you’ll be able to customize these commands, too.

There are plenty of great 13-inch and 14-inch laptops out there, but none that can defeat the M3 MacBook Air head-to-head. That notebook is the complete package when it comes to ultra-portable laptops.
