macbook air

Due to a recent surgery, I've been recovering at a location outside my home for a few weeks. I brought all my media with me on a spare hard drive, but one movie I had ripped but never transcoded wouldn't play on the 'Smart' TV here.

It seems to do okay with some H.264 profiles, but not the one for this 4K Blu-Ray rip. Therefore, I thought I'd transcode the file so it would play.

I also wanted to do other work on my laptop—in my lap. And unfortunately for Apple's latest M2 MacBook Air, there's no fan or heat sink to keep the M2 SoC cool.

And that meant the temperature around the top middle of the keyboard—and the bottom middle of the laptop—got quite uncomfortably hot with Handbrake's default settings, which would max out the CPU during the transcoding process.

I could encode anywhere between 10-18 fps at 4K resolution with x264, but the SoC temperature rose to 105°C and was uncomfortably hot within a minute or so.

Ah, the feeling of unpacking a brand new computer:

In my case, I'm actually selling the 16" MacBook Pro pictured above and replacing it with a 13" MacBook Air and 10 Gigabit Mac mini.

Once you turn on the new Mac, what's next? Do you:

(With a caveat: I'm compiling the ARMv8 64-bit Pi OS kernel.)

It seems every week or so on Hacker News, a story hits the front page showing some new benchmark and how one of the new M1-based Macs matches or beats the higher-priced competition in some specific benchmark—be it GeekBench, X86-specific code, or building Emacs.

Well, here's my quick story.

I've been doing a lot of work with Raspberry Pis lately—more specifically, work which often requires recompiling the Pi OS Linux kernel for the aarch64 architecture. I recompile the kernel enough I made my own shirt for it!

I recently migrated around ~50,000 photos and videos from Aperture to Photos (see my blog post on the process), and have also in a short amount of time upgraded my personal and work Mac laptops (both from older MacBook Airs to newer MacBook Pros).

On both of my new laptops—which were at least 3x faster than my older Airs—I noticed that Photos started completely fresh in its photo analysis for the 'People' album that shows everyone's faces. And after three weeks of seeing one of my CPUs stick around 100% all day every day (while plugged in), I started getting sick of this.

I would leave the Mac on all night, and check in the morning, and only 20-30 new faces would be recognized.

Some days it seemed it would take forever...

I like putting stickers on my laptops, to make them a little more personal. But I hate removing the inevitable sticker residue after peeling off stickers before I sell or pass on my old laptop.

In this video, I'll show you my current best technique for getting residue off most metal and hard plastic surfaces:

Let me know if you know of any better ways that won't mar the surface or take hours!

Yesterday UPS delivered a BTO 2016 MacBook Pro 13" with Touch Bar (to replace my 2013 11" MacBook Air), and a set of AirPods (to replace three different headsets I use daily in my work as a remote employee).

The two products tell a different story about the company that makes them:

MacBook Pro with Touch Bar

The MacBook Pro fails to 'thrill' in a way that no other Apple device I've made the conscious decision to purchase has.

Upgrading from a 2013 MacBook Air 11" (portability is king to me, but I needed more performance), the only major external difference is the retina display—something most other 'pro' Mac users have been enjoying since 2012. The Touch Bar itself is mostly useless to me for two reasons:

Update (3/4/14): Mac OS X 10.9.2 seems to fix at least the latency issue—and possibly dropped connections as well, at least for most users I've spoken with... We'll see!

Update 2 (11/25/14): If you're having trouble with iOS 8 and/or Yosemite, it could be related to AirDrop services over WiFi. Please see WiFried: iOS 8 WiFi Issue

For the past few months, I've been battling my 2013 11" MacBook Air's WiFi problems. I've taken the MacBook to the Genius Bar twice, and have attempted dozens of fixes. Judging by the number of individuals who have posted to this thread on Apple's Support Communities forum, among many other similar threads, I'm not the only MacBook Air owner suffering from WiFi issues like high latency, slow throughput, connection dropouts, and other random problems.

Here are some of the symptoms I and others have encountered:

I was migrating all the data from a friend's old MacBook (which was running Mac OS X Tiger) to her new MacBook Air (running Mac OS X Mountain Lion), and besides a WiFi hiccup, everything went smoothly (I had to clone the old MacBook's drive to a USB disk, then use Setup Assistant to migrate the data from that disk to the new MacBook Air).

During the Setup Assistant, I could easily connect to my WiFi network, but after the migration was complete, I couldn't connect anymore. I kept getting a pesky error: "Could not join [network]. A connection timeout has occurred." (see picture of error dialog here). Looking through Apple's forums and elsewhere was not much help, because this message seems to be a very generic 'something weird happened' error, happening in many different circumstances.

However, knowing that the keychain and old WiFi connection data from the old Mac had transferred over to the new Mac, and knowing that something might've gone screwy with the network information, I decided to do the following:

[Update: It looks like Mountain Lion finally restored this functionality—you can press Shift + Control + Power key, and the screen will immediately go to sleep.]

The 2010/2011 MacBook Air models are all amazing, and I believe Apple will eventually convert all their Mac laptops to the same basic design (just different sizes), forgoing the optical drives.

The only downside to this new design is the lack of an eject key—of course, most people probably only knew the key could eject discs, so it's no big loss for them. I, however, use that key in a standard Shift + Control + Eject combination to instantly turn off my Mac's display to conserve power and prevent any pixel ghosting. I've used the combo for a few years, and it took me some time to find out a way to reliably do something similar on my new 11" MacBook Air.

There are a few ways you can get this functionality back:

I was having tons of trouble getting my brand new 11" MacBook Air to get MobileMe Sync set up, and it kept getting stuck with 'Registering computer...' either when I checked the 'Synchronize with MobileMe' checkbox or when I clicked 'Advanced...' and then 'Register Computer'.

Since I've subscribed to iTools, then .Mac, and now MobileMe (soon iCloud) since 2000, I figured this may have something to do with the fact that, after all these years, my default AppleID would change to @me.com (rather than @mac.com, as it has been for years).

The steps you should try before giving up are as follows:
