100+ new features in macOS High Sierra

Say hello to macOS High Sierra, Apple's newest operating system update for Macs. Whether you're on an iMac or one of the Touch Bar-outfitted MacBook Pro models, there is a lot to love in this latest release of Apple's desktop operating system.

Apple’s new 21.5″ iMac with 4K Retina screen has user replaceable RAM and modular CPU

Apple during the Worldwide Developers Conference refreshed the iMac lineup with faster Intel chips and updated internal architecture. Good folks over at iFixit have now taken Apple's new $1,299 21.5-inch iMac model that has a 4K Retina display, discovering something really interesting.

The machine features both removable RAM (via a pair of removable SO-DIMM slots) and Intel's Kaby Lake processor that—surprisingly—sits in a standard LGA 1151 CPU socket rather than being soldered onto the logic board.

The modular CPU design suggests owners of the all-in-one desktop might be able to replace or upgrade the CPU in the future without a reflow station. The last time the 21.5-inch iMac had user-replaceable RAM was back in 2013. 2012 models of the 21.5-inch iMac also came with a modular CPU.

The stock configuration they tore apart had Intel's SR32W Core i5-7400 Kaby Lake chip, 8GB of 2400MHz DDR4 memory, a Radeon Pro 555 graphics card with 2GB of VRAM and a 1TB 5400-RPM hard drive.

According to iFixit:

Our teardown confirms that the new 21.5-inch iMac with 4K display has both removable RAM and a modular CPU. Of course, Apple would say neither is user-replaceable. Accessing and replacing these components isn't exactly easy, but we’re saying it’s possible. Maybe even probable.

A tinker-happy user (armed with the right tools and guide) could at least double the base 8 GB of memory, turning their new iMac with Retina Display into an iMac Semi-Pro.

Here's the machine's socketed CPU.

Other teardown highlights:

A warranty void sticker on the heat sink discourages users from removing the modular CPU underneath. The Retina display is manufactured by LG Display. There's a single microphone below the display vs. dual microphones on previous models CMOS battery is replaceable A built-in 3.5-inch SATA hard drive is upgradeable There's no SSD connector on the board

And here's the user-replaceable RAM module.

Despite the upgradable RAM and CPU, iFixit gave the machine a 3/10 for repairability.

That's because the computer is difficult to open as everything is buried under “a finicky glass panel,” in iFixit's own words. A speciality pizza-cutter-like tool is required to breach the adhesive before any repair.

And because the cover glass and the Retina display itself are fused together, the cost of a display replacement will be high.

At any rate, this is still good news for anyone in the market for a new iMac. Upgradability is paramount with all-in-one designs like iMac's. And with replaceable RAM and CPU, customers will be able to get more use and more years out of their computer.

New Surface ad wants you to think that your Mac “ain’t fast enough”

It's been only three days since Microsoft's advertising department unleashed a new ad salvo at Apple's direction in the form of a commercial for its Surface Pro 4 tablet/laptop hybrid and now it's posted yet another video to conveniently reiterate its message ahead of iPhone 7's launch tomorrow. Titled “Power of Touch”, the 30-second commercial doubles down on the ”the Mac lacks a touchscreen” theme.

Not only does Microsoft poke fun of the fact that Macs are long overdue for a refresh (yours supposedly “ain't fast enough” lately), but also disses the Mac for not shipping with a detachable keyboard or a stylus.

Weight, size, and battery life: iPhone 7 vs iPhone 6s

Apple's iPhone lineup just got even better as of Wednesday's product unveiling. Not only are the devices super fast, more power-efficient, and available in new finishes, but they also come with a slew of new finishes that owners of previous-generations of iPhone will drool over.

In this piece, we'll compare the iPhone 7 to the iPhone 6s so you have an idea of the differences in size, weight, and even their expected battery life.

iPhone 7 could provide at least 33 percent faster CPU performance than iPhone 6s

Alleged GeekBench CPU scores posted back in the summer suggested modest performance gains for the iPhone 7’s A10 chip versus the iPad Pro's A9X processor, but were debunked as fake soon after.

Today, genuine-looking results of the GeekBench 4 synthetic benchmark of the iPhone 7's CPU were posted on the website of PrimateLabs, the company that makes and sells the GeekBench suite.

According to the published data, the iPhone 7 could have its CPU performance boosted by at least one third, or about 33 percent, versus the iPhone 6s.
