GSAK. On a Mac.

You may recall back in 2012 I wrote about running Windoze on my Mac, mainly in order to try running GSAK without the pain of a Windoze PC. I tried Crossover. I tried a VM (Oracle’s VirtualBox). I was unimpressed. The idea of using GSAK died, as I was really, really, not prepared to use Windoze.


Recent conversations with my geocaching buddy, Bob, made me want to give GSAK another try, but how?

Turns out there has been some progress with Wine. Via the GSAK forum I found a very good guide on the subject, so I decided it was worth a try. Some of the detail (around versions) have changed but the basic steps are still the same. To begin with, I installed the beta version of Wine 1.8 (works with El Cap) but when I tried creating the GSAK App it crashed repeatedly, so I installed the latest “stable” release (1.6.1) instead. That worked perfectly.

So here’s proof (if you need it) of GSAK working on my MacBook Air:

GSKA screen shot

The key issue last time I tried running GSAK was that it wouldn’t connect to my Geocaching account. This time, a key step in the process involved installing GSAK on a Windows machine first, exporting a backup of the GSAK database and settings, and restoring these to the Wine version. That done (and my ancient Dell laptop returned to its rightful place in my tech museum), GSAK worked! I am able to connect to my geocaching data on, retrieve cache details, run PQs, etc.

The only function which seems to be missing from my Wine-bottled GSAK so far, seems to be the cache page in split view. I think this issue is linked to GSAK’s historical reliance on IE but I need to do some research on this. Nevertheless, clicking on a cache’s row launches the cache details in a new browser window (in Safari, my default). GSAK “sees” my Garmin GPS when I connect it to my MacBook via USB, so I can download GPX files to the device.

Early days, then, but from what I’ve seen so far it does look promising.



So, the other day I deleted an App from my iPhone in an attempt to fix a bug, with the idea that I would re-install the App thus fixing the bug. I then had a bit of mild panic because I couldn’t find the App in the App Store to download. Fortunately I remembered that the iPhone ‘hides’ purchased Apps so when I looked there, there it was. Phew. Unfortunately re-installing it didn’t fix the bug but that’s a different story.

The point is, whilst I was panicking, I thought I could always restore the iPhone from the iTunes backup on my Mac. Then I remembered how old that backup was. So today I backed up my iPhone and iPad to my Mac. While I was there I backed up some other key data on the iOS devices keeping those backups independent from the catch-all iTunes one.

A word about iOS backups: although you can backup your iOS device to iCloud (and it’s great that it does this automatically if you leave your device on, locked & connected to a power source), it doesn’t  backup everything (e.g. Apps!). It’s certainly worth doing a periodic iTunes backup as well.

Hint: turn on Encryption before hitting that ‘Back Up Now’ button, that way it will save all your logon credentials, saving you loads of time if/when you come to do a restore.


One more thing. Don’t forget to backup your Mac’s HDD (using Time Machine or similar).

Have you tried turning it off and on again?

IT Crowd - Roy

Yosemite has been playing nicely on my MacBook Air so I decided it was time to upgrade the iMac.

After doing all the usual safety procedures and testing the backups it was time to upgrade. The iMac has had a few OS X upgrades since I bought it – it came with 10.6 Snow Leopard – and I did consider doing a clean install. However the “normal” upgrade route has had good reports so I opted for that.

The upgrade proceeded smoothly to begin with and I left it to get on with it, however when I returned some time later it seemed to have stuck on the last install screen at 50% complete. I left it for about half an hour and nothing had changed so I did what any highly trained Mac technician would do.

I powered it off and on again.

That did the trick and the iMac booted happily. I had been pretty sure it had got stuck at the reboot stage of the process so turning it off and on again forced the reboot it should have done by itself. Just to be on the safe side I then restarted it up in Safe (or Single User) Mode (Cmd + S) and ran /sbin/fsck -fy. Next, I booted from the Recovery Partition (Cmd + R) and used Disk Utility to repair permissions on the iMac’s startup disk.

Since then it has been fine and I’m now in the process of reorganising my data files to take advantage of iCloud Drive.

Moving Time Machine files – Deja Vu

Having got myself a new external hard drive I decided to move my MacBook Air’s Time Machine backup from the old disk (which was full) to the new one. It was at this point that I remembered that I’d done this before and, what’s more, I’d written a post about it. Anyway, that was over 18 months ago so I thought I’d try Apple’s official method again. Ha Ha. Last time Apple’s method didn’t work, maybe it’s been fixed…

Apple’s official method goes like this:

  1. In Disk Utility, partition your new HDD as “Mac OS Extended (Journaled)” with a GUID partition
  2. Open the File Info window and make sure that “Ignore ownership on this volume” at the bottom of the “Sharing & Permissions” section is not checked.
  3. Turn Time Machine off
  4. Using Finder, copy the file “Backups.backupdb” from the old disk volume to the new one.

So I did this and, after an hour or so of happy copying, it failed. More accurately, it failed on specific files which it claimed could not be copied. To be honest I wasn’t surprised, given previous experience, so this attempt was made more as an experiment than with any expectation that it would work. Thing is, why does Apple continue to push this method when it has a reputation for not working? (You can look at the Apple Discussion Forums)

Last time I copied my Time Machine files, I used Carbon Copy Cloner to do a block-by-block copy but this time, I thought, Apple’s Disk Utility could provide the solution.

First off, I used Disk Utility to perform a repair of the old backup disk, to ensure that any file corruptions or permission errors were resolved prior to copying, as this could have been a reason for the Apple method failing. I did a Partition-level repair then a File-level repair. Interestingly, neither of these found anything to repair which sort of squashed that little theory. Ah well, on to the important bit. After formatting the new volume as per Apple’s instruction (above) I was all set. Here’s the method:

  • In System Preferences, turn Time Machine off
  • Connect both the old and new HDDs
  • Open Disk Utility
  • Select the original backup disk from the list in the left column and click the “Restore” Tab.
  • Drag the original backup disk volume (i.e. the one to be copied) to the “Source” field.
  • Drag the new backup disk volume to the “Destination” field.


  • Click the “Restore” Button.
  • The copy will take some time to complete. Once it has finished, the name of the destination volume will have changed to be the same as that of the original. This could be a bit confusing so eject the original volume.
  • You could change the name of the new volume but there is a risk (call that bitter experience!) that Time Machine will see this as a different disk and instead of carrying on as before, start a fresh backup and discard the backup history you were trying to retain in the first place. My preference was to simply eject the original volume before resuming Time Machine. After all, if the copy has been successful, the old one will no longer be required and after a decent period of mourning (just to be on the safe side) the old disk can be repurposed.
  • Back in System Preferences, turn Time Machine on. Enter Time Machine and check that you can browse the backup history. Do a sample file restore to check everything is working as it should. If that checks out, let it perform a backup cycle, afterwards checking that the backup history can still be accessed and restored from.

And that’s it. I won’t pretend this is a quick procedure. For some people it won’t even be necessary. You’ll need to consider whether you really need to keep a long range of backups stretching back a year or more. You could always keep the original disk somewhere safe for a while and allow Time Machine to start afresh with the new disk.

Lastly, if you do try either of the above methods, you do so at your own risk. What worked for me might not work for someone else. Before you undertake any file management activities make sure you have a robust backup of any important data.

Battery drain

Today my MacBook Air’s battery went from fully charged to 27% in a matter of a few hours, most of which was spent in sleep mode. Not good!

So I launched Activity Monitor and had a look at the Energy Impact readings. Wow! It reported Google Drive running at over 100. That was definitely not a good thing. So I closed the App down and re-launched it. This time Google Drive’s energy impact was at around 2.5. Much better!

I found that this issue has been reported in Mac discussion forums but not in any great numbers. So for now I’ll keep an eye on it, if the issue persists then I can always bin GD. Anyway, when Yosemite drops I will be able to try out the full iDrive experience. And if that’s as good as it’s cracked up to be, GD’s days will be numbered for me anyway.

The Washknight Tapes

Ha ha, well not tapes exactly but an interrogation nonetheless.

This chap I know, who caches under the pseudonym Washknight, has been pestering inviting the blogging cachers (or should that be caching bloggers?) he knows to post a response to a set of 20 questions. So I have, finally, managed to sit down in front of my Mac, roll my sleeves up in a purely figurative way, open a bottle of my favourite “thinking mixture” and, cracking my finger joints in the manner of the best piano virtuoso, peck out this missive on my keyboard.

1. When and how did you first get into geocaching?

A few years ago at work, the topic of geocaching came up a couple of times; finally one of my geocaching friends (you know who you are!) pulled up the map and it turned out there was a cache very close to my house. I went and had a look but didn’t do anything about it. Some weeks later another friend (The Bongtwashes) arranged an off-roading day in Berkshire. We stopped for lunch on our way to the off-road site and it “just so happened” that there was a cache nearby, so we set off to look for it. What I didn’t realise at the time (but  subsequently discovered) was that it is standard practice to arrange routes, lunch stops etc. so that they pass near to geocaches! Anyway after that I went back to find that local one near my home and that, as they say, was that.

So, David and Bob, I blame you for infecting me with this bug for which there appears to be no cure. 😀

2. Do you remember your first find?

Certainly do! It was the one I found with The Bongtwashes. It was “A Different Approach to Recycling” . What was extra special was that when Bob read out the hint I immediately knew where to look and I found the cache before he did! I think that is the last time that has happened (LOL)

3. What device(s) do you use for locating caches?

When I started out I used my iPhone running the Groundspeak App but, being a clumsy sort of fellow, I quickly became concerned that I would drop it into a puddle (or worse). At this point I bought a Garmin Dakota which is still my main device. This is backed up by my iPhone which I use mainly for mapping (more screen real estate so I can see the map and caches in a wider context) and for interrogating the web while I’m out and about. The GPS on the newer models of iPhone is generally excellent and I sometimes use it solo for urban caching, the ocassional ad hoc cache or the increasingly rare FTF attempt. Oh, and I always put my iPhone in an “All Terrain” case.

4. Where do you live and what is your local area like for geocaching? (density / quality / setting etc)

I live in Hertfordshire, and the borders with Bedfordshire and Buckinghamshire are only a few miles away; there are thousands of geocaches as far as the eye can see. The nearest (my second find) was less that 0.1 mile from my house. There’s a good mixture of easy trads, naughty nanos and tricky puzzles plus some really good rings.

5. What has been your most memorable geocache to date, and why?

This has to be the Virtual cache “The Empire Strikes Back”. A cache in New York. What’s not to like? It also scores as my “Farthest from Home” and “Farthest West”.

We visited the ESB on the night of September 11th, 2012. To say the views were spectacular would be putting it midly. To top an amazing evening we were able to see the memorial twin towers of light which were beamed up from the site of the World Trade Centre towers on every anniversary night. Stunning and moving. Just wish we didn’t have to see it.

6. List 3 essential things you take on a geocaching adventure excluding GPS, pen and swaps.

Just 3? Hmmm. Leatherman. Torch(es). Hat.

7. Other than geocaches and their contents, What is the weirdest thing you have discovered whilst out caching?

Other geocachers. 😛

Seriously, and perhaps a little disappointingly,  I haven’t found anything really weird. I have however found some unexpected things, some beautiful countryside and spectacular views. The strangest thing I can recall finding was an old-fashioned “Tanoy” loudspeaker high up in a tree, in a wood miles from any building of any sort. Very puzzling.

8. On a scale of 1 to 10 where 1 is I am obsessed by numbers and 10 is I am all about the experience and the quality of each individual cache. Where do you put yourself?

“I’m not a number, I’m a free man!” 🙂

If you look at my yearly stats you’d realise it isn’t all about the numbers for me. I have always enjoyed walking and so being out in the countryside, (preferrably with Skye our West Highland Terrier) is something I really do enjoy, so I guess it’s about the journey as well as the geocaching.

9. Describe one incident that best demonstrates the level of your geocaching obsession.

That’s difficult to answer because I’m not obsessed. There was a time when I would dash out for a FTF and I did get extremely wet completing a series of FTFs with The Bongtwashes in the pouring rain once. Note emphasis on the “once”.

10. Have you picked up any caching injuries along the way?

Only the usual scratches and dents from thorns, brambles and barbed wire. Usually on my head, which is why nowadays I always put my hat on when I have to burrow into anywhere and I always carry a simple first aid kit.

11. What annoys you most about other geocachers?

Hmmm. I don’t want to offend anyone. Some of them seem to take it a bit too seriously.

12. What is the dumbest thing you have done whilst out caching?

Trying to walk on something slippery such as sheet ice. That always ends badly in my experience.

13. What do your non caching family and friends think of your hobby?

In my house it’s called “Nerding”. They think I’m slightly mad. I’m not sure I have any non-caching friends…

14. What is your default excuse you give to muggles who ask what you are up to or if you need help?

My favourite is “I lost my dog” or variations of that. This excuse works even when I don’t actually have Skye with me.

15. What is your current geocaching goal, if you have one?

To complete the Chiltern Hundreds. Because it is there.

16. Do you have a nemesis cache that despite multiple attempts you have been unable to find?

There’s a micro in Pinner which I’ve never been able to find, mainly because of the muggle traffic. It has recently had a spate of found logs so maybe I’ll go back for another go soon.

17. What 3 words or phrases best sum up what geocaching means to you.

Challenging. Outdoor fun. Mud!

18. What prompted you to start blogging about geocaching?

I started my first blog in October 2005 as an evolution from MySpace (remember that one?). On my blog I write about whatever interests or (sometimes) annoys me, not just about geocaching.

After I found my first cache I posted a short item about it, it’s only recently that I have been writing about my geocaching adventures on a more frequent basis.

19. Which of your own blog entries are you most proud of.

I’m not sure I’m proud of any of my writing but I quite like this one  because it describes my best caching day (for numbers) and combines geocaching with another of my favourite pastimes – Green Laning.

20. Which other geocaching blogs do you enjoy reading?

To be honest I’m only just discovering the geocaching blogs, with two exceptions.

Washknight’s Geocaching Blind  which I’ve been following for a while now. His posts are entertaining and I like the fact that he is happy to take the p*ss out of the fact that he can’t see jack. Yes, I know he triggered this post but no, that’s not why I’ve singled him out for a mention in dispatches.

The other blog of note has to be Dr Solly’s.  It’s not just about caching, his technical tales appeal to my techie side. I’m not going to elaborate here, as he says; you either know him or you don’t.

Well, that’s the 20 questions answered, Paul. That was an interesting challenge which gave me pause to think, and travel back in time in order to research a response to some of the questions. I hope you (and anyone else daft enough to read to the end) enjoys reading my answers. 😀


There’s been a disturbance in the (Apple) force recently, due to Apple’s current Ad which seems to go against everything they’ve stood for in the past. Namely, giving owners “permission” to decorate their Apple products. For some, it seems a sacrilege to adorn one’s Mac with stickers, now here is Apple acknowledging that people like to personalise their Macs.

I love my MacBook Air, it’s my favourite bit of Apple kit after my iPhone. I like its clean lines, the unadulterated curve of the aluminium and would never adorn it with a sticker or (worse) a neon wrap. Still, plenty of people do. It’s a free country.

I just wonder if Steve Jobs is turning in his grave.


Website update

I’ve written a couple of geocaching/GPS guides from the Mac-user perspective. Most guides on the web seem to be for Windows users so I thought maybe something for MacIntosh users would prove useful for Apple geocachers. I may write some more. 😉

This gave me the excuse to rejig the site navigation so I’ve spent a while re-writing it with CSS-based menus, I’ve even gone so far as to develop a drop-down menu for the user guide pages. It took me a while but I think it works well and looks quite pretty too.

Anyway, have a look if you are interested:
