Yosemite won’t boot

Since upgrading our Macs to OS X 10.10 Yosemite, we’ve had an issue where Macs won’t boot up properly. They start up and show the grey loading bar, but it gets to 50% and then gets stuck there. Some hacks and tricks would sometimes help (like resetting the PRAM and repairing the disk and permissions), but not always. I hoped that 10.10.2 would fix things, but alas it has not.

It turns out that the problem was to do to with having the Mac bound to an Active Directory. Thankfully, I found a solution on the JAMF support pages from the contributor Chris Hotte. He suggests editing the rc.server file as follows:

  1. Boot into single user mode
  2. Type ‘mount -uw /’
  3. Type ‘/usr/bin/nano /etc/rc.server’ to edit the file
  4. Type in the following code.

    /bin/echo BootCacheKludge Beta 1.0 – Chris Hotte 2015 – No rights/blame reserved.
    /usr/sbin/BootCacheControl jettison

What’s the point of iPad?

If you go to any sort of Apple in Education event/conference/briefing, they often say that you should be really clear about the aims of any sort of technology deployment. This way you can then evaluate whether your deployment is working well or not.

Here are some of the aims (sometime conscious, sometimes unconscious) for the different stages of our technology rollout in school.


Purpose: provide computers that could do movie-editing and just generally worked (didn’t get viruses/fail to turn on most days).
Success?  Tick!

Teacher Mac Minis

Purpose: extend familiarity of OS X to teachers and therefore children, provide a bit more reliability.  Whilst supporting 4:3 screen ratios and not being too expensive.
Success? Mainly. The fact they had to run with ageing monitors/smartboards/projectors/sound systems made the experience rather less that wonderful.

Teacher 1:1 iPads

Purpose: familiarity with iOS, teacher exploration of new apps.
Success? Yes! Plus the bonus of teachers using email much, much more often.  And we got to try out the Great Smartboard Experiment.

Class sets of iPad minis

Purpose: more provision of computers to enable use of ICT across the curriculum.
Success? Moderate. It is happening, but not as much as it could.

So, how do we take our iPad deployment (for the kids) to the next level?

Some ideas…

  • Work out exactly how can iPad help with learning in English and Maths
  • Do some staff training on that
  • Support teachers

We’ve got a day with Julian Coultas in a week or so (courtesy of Toucan) where I’m hoping we can work out how to best move things forward.  Stay tuned!

GarageBand Pricing

I love this time of year. Not only does the latest release of iOS mean that I have an oodle of iPads to get updated (which takes varying degrees of time depending on how much free space is required to install the update), but a month after the mega IPHONE announcement, Apple calmly release a slew of other updates for the Mac and iLife/iWork. Yay. Last year’s came with quite a few headaches (such as the way iWork didn’t play nicely at all with SMB shares) but hopefully they won’t repeat this year. I’ve already tried saving a file over SMB with newest iWork, and it seems to work fine. The ‘proper’ file format they have finally created I’m sure is to thank for that.

Last year, GarageBand threw in a bit of a curveball by being free but requiring an in-app purchase to unlock all of the functionality. This is a system admin’s worst nightmare, as there is no decent way to do this upgrade on a whole school’s worth of iPads and apps.

Thankfully, it seems that this year Apple have rescinded on the in-app upgrade option and have slapped a price on instead. For new devices, you get the app free and on existing apps you get a free upgrade.

A few questions though:

  • What happens with Apple Configurator? Do we have to have app codes to install the app? Or even just to sync existing iPads with Configurator?
  • If we now need app codes, can we still apply for free ones on iPads bought in the last year?
  • What about codes for Macs?
  • I hope to make some investigations this week to find out more…

iPad Next Steps

So, it’s been about a month since we’ve enforced using an iPad to teach with rather than the use of a ‘Smart’board. Some teachers love and some are not so sure. The keen ones tend to be those new to the school (and so perhaps expecting to have to do things differently than before) and those who hate it tend to be the old hands.

Here are some of the things people miss:

  • On screen timers. I know the iPad has a timer app, but you can’t have a timer in the corner of a screen in Explain Everything.
  • Being able to watch YouTube videos easily. The iPad YouTube app sucks when it comes to AirPlay mirroring, so teachers are having to switch to Safari on the Mac.
  • Having a decent surface to write on. Some classrooms have separate whiteboards (of varying quality) whereas others are using flip charts a lot.
  • AirPlay mirroring isn’t always the most reliable thing in the world.

One solution to some of these problems is to add web browsers to Explain Everything and then add web timers designed for iPad. Handy!

To fix the other issues will probably involve getting decent whiteboards everywhere and installing new wifi.we shall see…

Early Doors

Kids have only been back in school for three days, but things seem to be going ok with the Great Smartboard Experiment.

Here are some things I’ve noticed:

  • There have been no complaints from teachers (well to me anyway…!) about the lack of Smart Notebook. There was a lot of  murmuring before the change about how it would be such a disaster etc., but now we’ve begun, it seems that teachers have found that using Explain Everything and a mirrored iPad isn’t so bad after all.
  • Some of the die-hard naysayers of Explain Everything have even told me that they love it!  Things like the laser pointer are really handy.
  • Nearly all teachers are giving Explain Everything a go.  I noticed that one teacher was using their own MacBook and Notebook on the first day, but it turned out that they had just forgotten to bring in their iPad that day…
  • Continuing staff training is still needed, such as with getting the hand of AirPlay mirroring or making use of how Explain Everything stops the iPad display from going to sleep.
  • Sometimes just using the Mac and PowerPoint or Safari and YouTube does the job fine.

I probably should do some more in-depth enquiries into what’s working for teachers, and what could work even better.  In many ways this is quite a seismic change to classroom practice and I think it will need continuing vision-casting and support.

Explaining Explain Everything

Today, as part of some INSET, I did some training with staff on how to use their iPads instead of their SMARTboards. It started off with some explanation of the reasons for the nice away from Notebook, and then some time exploring features of Explain Everything. We had two streams: one for those completely new to the app and those with a bit more experience.

I took the group who’d already had some training. These were the teachers who weren’t new to the school and so there was potentially resistance to this change. But I think people were reasonably open, particularly when fears were assuaged with cool things like importing/exporting to our school shared drive via WebDAV and “triple tap to overlap”. Oh, and capacitive styluses!

We shall see how it all goes as term begins…

Erasing SMARTboards

As my fun treat for finishing term, I got to go back into school the next day and begin the great SMARTboard revolution.  This involved going round to every Mac in the school and unplugging the USB cable (and in some cases, the USB-serial cable…these are seriously old boards), taking away the pens and completely uninstalling any SMART software on the computer (drivers, extras, Notebook software etc.).  It felt good!

Reflecting on my passionate dislike for ‘smart’ boards (what an ironically misnamed product: I wonder how they’d take my preferred moniker of STUPIDboard?), I think it comes down to the fact that they’ve never really worked that well and have never really gotten any better:

  • endless aligning to try and make the pens write as they should
  • really quite horrible software for the Mac (although it has improved in recent years)
  • glare and shadow from the projectors
  • projectors!  Projectors are great in a darkened room (e.g. a cinema), but not in a bright classroom.  Plus the image quality degrades steadily but inevitably over time until you can barely see anything.
  • trying to make a mouse and keyboard user interface work with touch.  Apple have explicitly sworn off this idea (hence the iPad), but SMART seem to blithely carry on regardless.  I cannot count the amount of times I’ve tried to tap on some element of the user interface, but then for it to not quite be aligned correctly and so I give up and use the mouse instead.
  • really fragile board surface that results in areas of the board that just don’t work properly
  • have I ever mentioned the cost?  £2000 for a glorified trackpad is expensive in anyone’s book.

But I cannot sit back and bask in my delight for too long, as the challenge of communicating/demonstrating/inspiring teachers about how an iPad can be the smart man’s smart board still stands.

Thoughts on Notebook

As I’ve mentioned before, from September we are getting rid of SMART Notebook in our school and unplugging all the the SMARTboards. This is not a move without controversy and so there is a certain amount of vision-casting that will need to be done with staff to explain why this happening.  To help me get my thinking straightened out with it all, I thought I would do a preemptive response to possible/probably questions about it all.

I don’t see what’s wrong with Notebook

In our school, about a quarter of the installed boards are so old that they are no longer supported by SMART and so don’t work.  Another quarter are non-SMART interactive LCD displays that can’t be touch enabled and still use Notebook (due to licensing issues). Of the other half of boards that are reasonably new and should (in theory) work, a good proportion of them suffer from some damage to the surface which means they are pretty unusable on a day-to-day basis.

So the options are:

  1. Carry on as we are, with a few pioneers using Explain Everything on a mirrored iPad to give true interactivity, with everyone else using Notebook as a glorified slide deck
  2. Replace all of the boards with new SMARTboards
  3. Ditch SMART Notebook and unplug SMARTboards and move over to mirroring iPads using Explain Everything
Option Pros Cons
1 Teachers already know what they’re doing. Previous years’ resources can be reused. No or limited interactivity. Costs involved with updating Notebook software (which will inevitably need to be done following OSX upgrades) – an unknown, but could potentially be £kkk.
2 Teachers already know what they’re doing. Interactivity is restored. Very expensive and means budget cannot be spent on other stuff, like more class sets of iPads.
3 Reliable interactive surface is the iPad. Can make use of all the power of the iPad in the classroom, through camera, microphone etc. Taking the school forward rather than sticking with a fading and disrupted technology that is the SMARTboard. Teachers have to learn a new tool. Previous years’ resources cannot easily be reused. Potential opposition from staff!

Ok, so I can see that we need to make a change. But can’t we just keep Notebook anyway?

What is interesting is that we’ve had a year of this situation, and only a few teachers have taken up using an iPad instead of Notebook on the Mac.  Teachers are busy people who have got plenty of other things to think about, and I guess tweaking your pedagogy to incorporate new technology isn’t high on the list of priorities.  But if we don’t make a move, we may suddenly hit a brick wall in the future.  Say, for example, Notebook 11 doesn’t work on OSX Yosemite come Autumn.  Do we hold back our Macs to keep Notebook working?  Or pay lots of money for licensing the newer Notebook?

What’s so great about using a mirrored iPad and Explain Everything?

  • Cameras = visualiser anywhere in the classroom
  • You can teach from any point in the classroom – no wires!
  • You can teach facing your class
  • No need to align your interactive display on a daily/hourly basis ;-D
  • Cool screen recording stuff
  • Multi-touch interaction of onscreen elements
  • Using a user interface that is designed for touch

How can I write?

Classrooms have all got some other form of whiteboard/flipchart if you want to do some proper modelled writing.  But for scribing stuff, we’re investing in some proper capacitive styluses for teachers to use.

How can I share files across my year group?

We have a webDAV server that is accessible in and outside of school using the normal secure logins.  This allows you to open Explain Everything files from the shared drive and export them back there again.

What if I desperately need to open a Notebook file from previous years?

SMART have an online version of Notebook at http://express.smarttech.com where you can open files from your computer.

Giving up on Profile Manager (Again)

Today I was busy setting up some new iPad minis for school.  Apple Configurator is getting increasingly reliable and stable, so didn’t hit too many issues with that.  However, I then hit a problem that I couldn’t get the devices to enrol on Profile Manager.

Now, I’ve spent several years trying my best to get Profile Manager to work.  On Lion, it was basically broken. By Mavericks, it had improved quite a lot.  But it was never fully reliable, with odd quirks coming up every now and again.  There were some cool features, such as the use of variables when setting up things such as email accounts.  But the downside to this was that when the Mac server decided to lose the link to our Active Directory, this resulted in all of the teachers’ email settings being removed from their iPads. Not fun.

Now, I have used Meraki before, which has a free MDM solution.  It doesn’t do everything and can be a bit confusing to use, but it is certainly reliable.  And free.  So today I decided that I would use Profile Manager to actually build all of my profiles (which it is really good at, e.g. email settings, restrictions etc.) and then use Meraki to deploy them.

And so far, this seems to be working fine!  The only downside is that I have to remove every device from Profile Manager and enrol them onto Meraki instead, but I’m having to do a bit a refresh anyway, so it shouldn’t be too much work as well.

Keynote takes on SMART Notebook

As I have mentioned before, our school is ditching SMART Notebook from September.

But since that decision was made, we discovered a cool new feature in the iOS version of Keynote.  The feature is officially called ‘highlighter’, which basically adds the ability to write with your finger when you are presenting mode. There has always been a laser pointer when you tap and hold, but now a set of coloured pens appear as well.  You choose the colour you want and can then write where you wish.  Instead of swiping between slides, you now get some arrow buttons on the left and right of the screen to change slide.  All of you annotations stay even if you change slide, but they disappear when the slideshow ends.

The particularly cool thing about this is that there is now another alternative to Notebook on iPad if all you want is slides and the ability to write on them.  The other cool thing is that, because of iWork file compatibility, you can make your Keynote slides on your Mac (or even on iCloud on a PC) and then use them for teaching on your iPad.  This is good for those teachers who don’t feel they will be as fast making slides on ExplainEverything because they have to be created on the iPad itself.  (I personally don’t think it’s any slower, but I guess it makes the transition easier.)  And with iCloud, the slides should ‘just’ be there (in theory!).

Here’s a slightly provocative screenshot:
