How to Enable Trackpad Dragging on OS X

Problem:

I have recently updated the OS X to Yosemite on my Mac Air. All was good except that the “double tab on the trackpad to drag an item around the screen” function stopped working. I had a look around in the System Preference but couldn’t find anything. Mainly because I didn’t know that the “double tabbing on the trackpad to drag stuff on the screen” action was actually called “Trackpad Dragging“! Else, it would be so much easier to search the Mac or the Internet for a fix. I tried to live without of it but soon the annoyance was creeping up on me. After a bit of persistent research, I found where Apple hid the option to enable “Trackpad Dragging“. The following explains How to Enable Trackpad Dragging on OS X:

Solution:

  1. Go to System Preference system-preference
  2. Click on Accessibility accessibility-icon
  3. Scroll down to Mouse & Trackpad accessibility
  4. Click on Trackpad Options
  5. Select Enable Dragging
  6. Select option With Drag Lock
  7. Click OK

eBooks: iBooks Author or Pages

I am a big fan of eBooks. I have many eBooks in formats other than .epub so I wanted to convert them into the proper eBook format – ePub. How difficult can it be? It turns out that its easy to make your own eBooks as long as you know the basic rules and tools.

Tools I use:

Notes on the tools:

  • iBooks is an eBook reader. It’s not a perfect software but it enables me to read everywhere and from any of my iOS devices. The main feature that I enjoy the most is that I can read a book on one device and continue reading on another device in anther room, at exactly the page I was on last.
  • TextWrangler to me is equivalent to Notepad++, a text tool that recognise a lot of syntax from programming languages. I even use it to write instead of Word.

iBooks Author vs Pages:

iBooks Author and Pages can be both used to make eBooks. I tired both and found out that there is a Golden Rule – Books made with iBooks do not let users changing the font size. To me, that’s just stupid. 🙂 Because that I read a lot, I have my books all set to certain font size for easy reading. To me, this is the biggest fail for iBooks Author.

In short, if you want to make an eBook with loads of interactive features and multi-touch gestures (e.g. pop-up videos that expand, galleries of images on the same page) use iBooks Author; use one of the preloaded beautiful templates. I think that Apple pushed it out only for professional e-publishing purposes so the teaches can make their own textbooks etc. Click here to see beautiful examples of eBooks published by iBooks Author.

If you want to make an eBook with loads of texts, Pages can do the job for you simply. I had to use this option. You can still include video and audio files in your eBook with Pages but they won’t function as smooth as the ones in iBooks Author.

Apple‘s recommendation is to use the ePub_Best_Practices_EN.pages as a template for producing eBooks. I tried different Pages template and I had to admit that the template is well optimised for eBooks. I used another template, the eBook it produced was much slower to open and the font was not great to read with either.

iMessage Not Showing on Multiple Mac

Problem:

SMS texts messages are received on iPhone fine but is only forwarded to one of the Macs, regardless of the model of Mac.

I have a slick Mac Air that I take with me everywhere and a sexy iMac at home. To keep all my offline data synced, I find it easier sometimes just to restore my Mac Air to the iMac or vice versa. The restoring process is not difficult, just use the Migration Assistant with the connection to a Apple Time Machine.

I soon find out that the SMS text messages that I receive on my iPhone would only be forwarded to one of the Macs, not both. I turned off iMessage on the iPhone then enabled it again but I can only see one of the Macs displayed under the Text Message Forwarding option. For example:

text-message-forwarding

text-forward-iMac

My research online led me to an Apple Support Forum. The poster Macsterguy explained this error as a Keychain issue which made total sense. Because the user on one Mac was restored from another, it would be possible that for the users on both Macs, the restored and original, to have the same user ID (UUID). In that case, the two Macs could be misinterpreted as one to the iPhone. Follow these steps to check the user UUID:

  1. Open System Preferences
  2. Click on Users & Groups
  3. Right click on the user in the current user list
  4. Select Advanced Options (if this does not appear, check that the “Click on the lock to prevent changes” option at the bottom of this window has been turned off.)

I would not advise you to change anything under the Advanced Options.

Solution:

  1. Turn off the iMessages option under Messages on the iPhone (see the image above for the location of the option)
  2. Login to ALL Macs as the restored user
  3. Sign out of iMessage on ALL the Macs via the Messages application
    1. Open Messages application on the Mac
    2. Go to Menu
    3. Click on Messages, then Preferences
    4. Click on Accounts tab
    5. Select the account then click on the Sign Out button
  4. Quit the Message application on ALL the Macs
  5. Open the Keychain application on ALL the Macs
  6. Backup the key “com.apple.ids: localdevice-AuthToken” on ALL the Macs
  7. Delete the key “com.apple.ids: localdevice-AuthToken” on ALL the Macs
  8. Restart ALL the Macs and the iPhone
  9. Sign in to iMessage on ALL the Macs and the iPhone

Now you should see multiple devices listed in the iPhone.
