The wait is finally over: the new QGIS 2.8 “Wien” has finally been released for MacOS as well! Following the (kind of) tradition of my articles showing how to install QGIS 2.6 2.4, and 2.0 on MacOS, I now sat down to write a brief walkthrough for the latest version as well.

Setting up QGIS 2.6 on MacOS X 10.10 Yosemite
It’s been awfully quiet here on the blog recently. This is owed to some major changes in my life, including the successful end of my PhD program, a successful job hunt, a move from Japan to Germany, and an interesting yet challenging start in my new job at a major German research institute.
But the recent release of MacOS 10.10 “Yosemite” together with the even more recent release of the new QGIS 2.6 “Brighton” was a brilliant opportunity to not only bring back some life here, but also to continue my mini-series of articles about installing and running QGIS and other rather scientific software packages on the latest versions of MacOS (see here, here, and here for example).
So I sat down on my freshly delivered sofa between unpacked boxes to try my luck. To make a long story short, in my case the installation ran smoothly and was done in about half an hour – downloading the necessary disk images took most of time. But before I updated my QGIS 2.4 to the new version 2.6 I first tried if 2.4 still runs on my freshly upgraded MacOS Yosemite. And there was a small surprise waiting for me here, as MacOS asked me to update my Java SE 6 runtime!
Luckily this was no big deal, since the error message provided a link to the download page at Apple.
After running this update QGIS 2.4 worked fine like before.
For the download of QGIS itself I decided once again for the packages provided by William Kyngesburye a.k.a KyngChaos – not only did I never have any problems with these, but to my best knowledge they are the only available pre-compiled QGIS packages for MacOS… The installation process follows the steps known from earlier releases:
First is the new
GDAL 1.11. The installation is as easy as downloading the
DMG and installing
GDAL from the respective
PKG therein. Please ignore the
NumPy package also contained in the
GDAL disk image, since it’s an outdated version. Oh ya, and then there’s this thing that’s still annoying me:
Gatekeeper refuses to open applications and packages from “unidentified developers” (that is, developers that can’t afford a certificate by Apple) by double-clicking. Hence you need to right-click it and select
Before we can install
matplotlib we need to install
NumPy. There you can find the most recent version 1.8.0-1. As is stated on the website
NumPy is “included on the
GDAL Framework disk image, though it may not be up to date”. And indeed the
GDAL image mentioned above includes
NumPy 1.6.2-1 from mid-2012…
Now that that’s out of the way we can install
And finally QGIS 2.6.0-1 itself. As in the other cases we open the
DMG file and install from the
PKG file therein. That’s it!
Now that everything was installed it was time to fire it up for the first time. And lo and behold, it works! Just like that. You can’t ask for more. Now it’s time to discover all the great new features QGIS 2.6 brings!
The Short Way to QGIS 2.4 Chugiak on MacOS
Today I finally found some breathing room in my projects to dare updating my MacBook Pro (running MacOS X 10.9.4 Mavericks) from QGIS 2.0 (Dufour) to the recently released version 2.4 (Chugiak). Well, to be honest I also realized that I should update to be able to use the
QgsFeatureRequest.setFilterExpression() method to make use of filtering expressions (introduced in version 2.2).
The first step was to download the installer images for QGIS 2.4 and
GDAL 1.11 from KyngChaos.
GDAL disk image contains not only the complete
GDAL framework (including the
UnixImageIO frameworks), but also
NumPy. Since version
1.6.2-1 is dated from end of August 2012 I decided to skip installing, since I installed my
NumPy later than that and should therefore be up to date already. The
GDAL installation worked without a problem.
Next step was the installation of the actual QGIS 2.4. The readme files recommend to delete any existing
QGIS.app file from the
Applications folder, so that’s what I did. The installer then confronted me with this error message:
"QGIS requires the Matplotlib python module (kyngchaos build)."
matplotlib 1.3.1-2 from early 2014 can also be found on the KyngChaos website, so I installed that from the disk image (root authorization necessary) and went back to the QGIS installer. When the installer presented me the readme file once again I realized that I had apparently just read over the hint that not only
NumPy but also the
matplotlib python module was required – classic user error on my end!
The QGIS installer also requires root authorization, takes few minutes and about half a gigabyte of hard disk space. After the small hickups earlier it finished without a problem, and I was presented first with the beautiful new splash screen and then the GUI itself. Side note: I love the fact that QGIS remembered all my settings regarding toolbars, window locations etc.!
Huge thanks and props have to go to the team behind QGIS – I can’t wait to look for reasons to try out all the new features. For a quick overview I can recommend Nyall Dawsons blog, whose most recent blog articles provide both an overview of and also some details about what’s new in QGIS 2.4.
