Fix Messages’ image pasting by killing its engine

Kirk McElhearn explains how Messages in Yosemite has trouble sending pasted images. These problems typically only occur between people who use AIM accounts in Messages; sending pasted messages when using iMessages' accounts seems to work fine. (I use an AIM account to keep iMessage traffic off my main Mac, and for its great screen sharing.)

Kirk's article details the fix, which is to kill the imagent process, which is what controls Messages. He uses Activity Monitor to do so, which works fine. But I have to kill the stupid imagent many times a day, so I wrote the World's Easiest AppleScript™ to do the work for me.

Send your Retina iMac’s desktop to deep space

Last week, I used the just-released Hubble Space Telescope images of the Andromeda galaxy to create a couple of desktop images for my Retina iMac. I liked the results so much that I spent some time collecting other suitable images from the Hubble site, and then cropping and/or scaling them to create interesting high-res desktop images. (I used Acorn for all the edits; it had no troubles, even with TIF images as large as 20,323x16,259!)

The end result is a collection of 50+ Retina iMac-sized (5120x2880) desktop wallpapers, courtesy of the Hubble Space Telescope. Here's the full collection:

Tip: If you click on the caption below the image, you'll be taken to the source page on the Hubble telescope site where I found the image.

There are at least two versions of nearly every image—one or more where I cropped out an interesting area of the photo at 5120x2880, and one where I scaled down and then cropped as needed to get as much of the full image as possible.

There are three ways to get an image (or all the images):

Method One: One at a time

  1. Command-click on the image (anywhere other than on the navigation arrows) you'd like to download. This will create a new background tab (in Safari, Chrome, and Firefox, at least), loaded with that image's high-resolution page on my OneDrive.
  2. At the top of the page you'll see a Download icon and text; click there to save the file to your Mac.
  3. Repeat for each image you want, and then organize as you wish, and set them up as rotating desktop images.

Method Two: Another way to get one at a time

Open the full folder on OneDrive, and browse/download directly from there. Click on any image, then click the Download icon to download the selected image to your Mac.

Method Three: Gimme the full set!

If you want all 54 images, just download this zip file from OneDrive.

Span one large image across multiple printed pages

I was looking for a way to print a large image across multiple pages, so I could make my own do-it-yourself poster-size printout. By way of background, I wanted to print a huge virtual fire, to cover a piece of insulation we put in front of a drafty fireplace in the winter. (We don't like to burn wood, so the fireplace goes unused, but staring at a piece of shiny foam insulation all winter isn't all that interesting.)

Conceptually, this seemed pretty easy: find a huge image, open it in some app that handles images, and print. What I found is that doesn't work, at least not in the apps I had at hand (Acorn and Preview). After some web searching, I stumbled across an odd but effective solution: use Excel.

Open a new blank Excel workbook, then select Insert > Photo > Picture From File, and select your massive image. Now when you hit Print, you'll see the output spans multiple pages. I used Page Setup to select a borderless US Letter size, and printed out 16 pages of a roaring fire.

After some cut-and-tape operation, the drafty fireplace's insulation became more visually appealing:

Note that this was a "proof of concept" operation, so I printed in draft mode (hence the vertical striping on the printout) and wasn't overly careful about lining up the pages. I had originally planned to print the final version on glossy photo paper, but instead opted to buy a 36x48 poster-size printout from an online vendor. (I haven't yet received the print, but when I do, I'll post about its quality. Until then, though, I don't want to link to the vendor, as I don't yet know what I've bought.)

I knew Excel could do a lot, but I never thought to try it for printing huge images across multiple pages.



Fun with iTunes’ new math

Unlike my previous incidents with iTunes and iOS devices, today's report isn't on a sync problem per se.

It's more like a math problem which then leads to a sync problem. Here's the tl;dr version: I have an iPad with 5GB of free space, and I cannot add a 1.8GB movie to it, as iTunes eventually tells me it needs another 526MB of space in order to do so.

During the attempted sync of this movie, iTunes displays some horridly bad math skills; just watch the video to see.


Here's the video at its full size (1164x1056).

I have no idea how to resolve this, short of restoring the iPad, which I'd rather not do. (I've already unsynced and resynced everything, in an attempt to straighten out the math, but to no avail.)



Use your Marketing department to drive away prospects

I needed to install a demo version of Parallels Desktop for Mac to work on an issue some of our Many Tricks customers are having with Witch.

On Parallels' site, when I clicked the "Try It Free" button, I was greeted not with a download, but with a dreaded email harvester:

Unless I was willing to provide an email address, I was not going to get the demo. To Parallels' Marketing department, I'm sure this is viewed as a huge win: "Look, if we require an email address to get the demo, we'll build a massive mailing list of potential buyers!"

But to a prospective customer, what this harvester says is "we really don't care about your experience, we want to harvest your email address."

An email harvester is only as useful as what it harvests. And from me, and I suspect many others, it harvested a "I only use this for junk mail" email address. So while Marketing is collecting a huge list of email addresses, that list is littered with any number of useless addresses.

Contrast this approach with VMWare's Fusion demo download: Click one button, and the download begins. In the past, VMware also collected email addresses, but it seems they've realized that building a huge list of mainly worthless addresses is, well, worthless.

Unfortunately for Parallels, using the demo is even more annoying than downloading it, "thanks" (again) to the Marketing department.

Revisiting iTunes/iOS sync issues

After getting my iPhone 6 in early October, I was initially excited by all the cool tech in my new phone. Until I tried to sync it, that is. I eventually got so frustrated that I emailed Tim Cook for help. From that email, I wound up talking to Apple's engineers, who eventually solved my sync issues—it turns out they were related to duplicates of long-ago-purchased songs.

Welcome to
Sync Hell

And for a while, things were great in iPhone 6 land. Then I ripped a few new CDs, and noticed that they didn't show up on the phone. Uh oh. Even worse, when I looked at my iPhone in iTunes, the Music section contained hundreds, if not thousands, of the dreaded gray dotted circles.

This seemingly innocent symbol means that the indicated song did not sync—the information about the song made the journey to the phone, but the song itself did not. Argh! Read on to see how I muddled through this issue, with some advice that may, or may not, help you with your own sync issues.

If you don't want to read everything, here's a tl;dr version:

  • My iPhone sync issues returned, along with a huge-fake-but-limiting amount of data shown in Other.
  • There's a known-to-Apple "very slow performance" issue in iOS/iTunes that can make some iPhones sync very slowly (fixes have been made, but not yet released).
  • A factory restore failed to complete until I rebooted the iMac.
  • After the restore, the sync worked, but I still had a huge Other category.
  • After the iOS 8.1.1 update, the huge Other category vanished.
  • I had to manually unsync/resync a number of songs to clear their gray dotted circles.
  • It may help to do a voodoo dance, sacrifice three Nokia phones, and rub your stomach while patting your head before syncing.

Read on for the gory details…except maybe for that last item, which I totally made up.

Seeking clarity in Retina iMac desktop images

I'll admit it: I'm a desktop image (nee wallpaper) addict. I love to use a wide variety of images, and change them often throughout the day, just to keep my work environment fresh. On my two external displays, I use iPhoto images—general photos on one, kid pictures on the other. But for the main iMac screen, I prefer to use photos taken by others—typically stunning landscapes and cityscapes from all over the world.

With the arrival of my 5K iMac, however, my existing collection was no longer sufficient. Yes, they were all 2560x1440 images, which matches the "apparent" resolution of the Retina iMac. But in order to make that image fill the Retina iMac's screen, it's first scaled up to 5120x2880, then displayed by OS X at 2560x1440. As a result, my desktop images aren't nearly as sharp looking as they were on my old 27" iMac's display.

As an example, here's a segment of two versions (2560x1440 and 5120x2880) of the Sydney Skyline, as screen-captured when set as my Retina iMac's desktop picture. As you move the divider bar right, you're revealing more of the 2560px version; move it left, and the 5120px version takes over.

After scrolling back and forth a bit, you might be thinking these pictures are identical, and I'm just seeing things. While I may be seeing things, the pictures are not identical. (Compare some closely-spaced lights and the crispness of vertical lines in each image to spot the differences.)

Read on for a closer look at the image, which really shows what you're losing by using a 2560x1440px desktop image on a Retina Mac…as well as a list of places I've found that have 5120x2880px images available.

Yosemite’s constant clattering clutters Console

For those who aren't familiar, Console (found in Applications > Utilities) is an application that shows you what's happening beneath the lovely skin of OS X. Open the application, and you'll see a combination of status and error messages from any number of sources.

If you've never looked at Console before, you might be surprised by just how much stuff gets written there. But with the release of Yosemite, things have really taken a turn for the worse—the amount of stuff written to Console is greater than I recall for prior OS X releases.

As a test, I set up a new Yosemite virtual machine, installed ScreenFlow (and nothing else), then launched and interacted with a number of Apple's apps for two minutes while recording the screen. The results are quite sobering; here's what two minutes of Console logging looks like, reduced to a 10-second movie:

As you can see, there are a lot of Console entries in just two minutes.

Encrypt files then backup to a cloud service via script

Most cloud services tell you that their data stores are safe, that your data is encrypted in transit and on their drives, that employees don't have access, etc. For the vast majority of the stuff I store in the cloud, this is more than good enough for me—the data isn't overly sensitive, and if someone were to hack their way in, all they'd get are a bunch of work and personal writing files and some family photos.

For other files—primarily financial and family related—those assurances just aren't enough for me. But I still want the flexibility and security that comes from having a copy of these files in the cloud. So what's a paranoid user to do to take advantage of the cloud, with added security, but with a minimum of hassle?

The solution I came up with involves using local encrypted disk images and a shell script. Using this script (and some means of scheduling it), you can automatically encrypt and back up whatever files you like to a cloud service.

Use two CD drives to import multiple CDs into iTunes

I happen to have two external drives connected to my iMac—one that reads and writes the usual mix of CDs, DVDs, etc., and another that includes Blu-Ray playback (but not writing). Today I discovered that you can use both drives at once (sort of) to speed up multiple CD rips. Here's how it works.

When you have two drives in iTunes, you'll see one CD icon in the iTunes 12 bozo bar—that's my name for the row of device controller buttons seen at right.

Click on the CD icon, though, and you'll see both inserted discs are available:

There really isn't a trick to using two drives at once in iTunes, other than saying "Yes" when this dialog appears onscreen:

iTunes won't actually rip both CDs at once, but it will queue the second CD up, and start ripping it automatically when the first one finishes. As soon as you see that changeover, click on the CD icon and switch to the just-imported CD.

Eject the just-imported CD, insert the next CD to rip, and say "Yes" again when iTunes asks if you'd like to import it. Repeat as necessary, until you're done. I imagine that if you had three CD drives, this would work just as well—I can't test that assumption, though.

While not fully automated batch ripping, this process does let you make relatively quick work of a stack of CDs—for those of you who (like me) still prefer such relics of a prior age.
