There’s good news and there’s somewhat annoying news.

The good news is that the new 2015 21.5-inch 4K Retina iMac supports up to 64GB of Ram, an impressive jump from the previous model’s cap of 32GB of RAM.

The bad news is that this RAM is soldered into the logic board and that 64GB of RAM will have to be built to order from Apple.


Apple supplier advantage studied, analyzed

There’s been some astonishment as to the new iPhone and its A9 processor that people are trying to get to the bottom of.

Namely, the iPhone 6s and its 3D Touch screen, which has been commented as feeling “like magic” and outsiders realizing that Apple as a platform company is so far above the competition it’s hard to fully grasp.

That being said, one wonders why pushing down on a 3D Touch screen feels so responsive and whether the hardware or the software is to credit for this? Following up on this is the question as to how Samsung and TSMC, which both produce A9 processor variants for Apple, were able to optimize the chip using a different process and library, were able to get this exactly right?

Just as there are many misunderstood reasons for Apple’s overall success, justification as to how Apple produces superior products isn’t superficially visible.

These could smack of the nifty.

In the wake of the controversy surrounding the iPhone 6s and 6s Plus’ battery life and how this might change depending on whether the battery was sourced from Samsung or TSMC, some research has been done that has discovered the battery life difference in “real-world usage” to be about 2 to 3 percent.

The cool cats at Ars Technica ran two iPhone 6s models, one with a Samsung chip and one with a TSMC chip, through their paces, to find the following results:

It wasn’t in the release notes, but Facebook quietly added it anyway.

The Facebook iOS app, which just hit version 41.0, added full 3D Touch features this morning.

The new version allows you to use a long, sustained tap on any iOS device with a 3D Touch screen to perform functions like writing a post of uploading photos or videos.


Some users report email-based issues after iOS 9 update

A bug fix may be in order.

Since its release on September 16th, a number of iOS 9 users have reported having trouble opening emails with attachments. There’s currently a 22 page thread on the Apple discussion forums covering the issue, which currently has more than 200 replies from users who are all experiencing the same problem.

The issues, which cover a wide range of devices, often report a “Message not yet downloaded from server” error whenever they attempt to open an email message with an attachment. The problem appears to be affecting Apple customers who have POP email accounts and is causing issues with both new and old emails.

Deleting email accounts and adding them back in does not fix the issue, but downloading an alternate email program from the App Store seems to have worked for many users as a temporary fix. Turning off Wi-Fi also allows some users to read their previously downloaded emails and access attachments, but images are not viewable.

It’s not unexpected by any means.

And it’s a cool bell and whistle.

Apple has published changes to its tech specs following its September 9th announcement of the 2015 iPhone 6s, iPhone 6s Plus, iPad Pro and iPad mini 4. With these changes, Apple quietly modified the tech specs and comparison pages for 2014’s iPhone 6, iPhone 6 Plus, and iPad Air 2 to bump them all from Bluetooth 4.0 to Bluetooth 4.2, the latest version of the increasingly popular wireless standard. While the sixth-generation iPod touch shipped with Bluetooth 4.1, the original iPad Air, iPad mini 2, and iPhone 5s all remain on Bluetooth 4.0.

AT&T activates Wi-Fi calling feature for iPhone 6, 6 Plus, 6s and 6s Plus handsets running iOS 9

At long last, AT&T has activated Wi-Fi calling.

The carrier has apparently activated this feature, assorted customers having stated they were able to activate Wi-Fi calling on their iPhones.

Wi-Fi calling is a feature that lets calls be placed over a wireless connection when cellular connectivity is poor, functioning much like an AT&T M-Cell does now. It’s similar to Apple’s own FaceTime Audio feature, which also routes calls over a Wi-Fi connection.

The feature can be activated by going into Settings, then the Phone section, then toggling on the Wi-Fi calling feature. From there, there are a set of steps to walk through, including entering an emergency 911 address. Wi-Fi calling is available on the iPhone 6, 6s, 6 Plus, and 6s Plus running iOS 9.

The expensive, unlocked, SIM-free iPhone 6s and 6s Plus handset you’ve been waiting for has arrived.

Two weeks after the launch of the iPhone 6s and 6s Plus handsets, Apple has added a new purchasing option for the devices to its online store. As of yesterday, customers can now buy an iPhone 6s or 6s Plus SIM-free, unlocked, and without a carrier.

The units arrive without a commitment to a carrier or carrier financing. Apple has also noted that the device does not come with a nano-SIM, meaning that customers can go to a carrier of their choice and get a SIM, assuming the carrier supports the wireless bands the iPhone has. The entire cost of the iPhone must be paid upfront.
