Mac OSX Yosemite and Pentaho Kettle 5.2

yosemiteThe last two weeks has seen a couple of new software releases, and as always, not everything plays well together out of the box. Apple released Max OS X Yosemite (10.10) as a free upgrade, and Pentaho released Kettle (aka Pentaho Data Integration- PDI) community version 5.2.0. Upgrading both apps on my Mac went very smoothly (the Apple update does take several hours).

However, once I tried to run Kettle, I first got a message that Java was not available. After several security issues with Java, Apple removed it from OS X earlier this year. Apparently during the Yosemite update, Java gets removed again. Its an easy fix to get it back and the message that appears when trying to run a Java based app points to where to download an updated version for OS X. Download and install that.

Try and run PDI again, and an error message about the file being damaged is displayed.  Sigh. Continue reading “Mac OSX Yosemite and Pentaho Kettle 5.2”

Pentaho Kettle Spoon – Damaged message on Mac OSX Mavericks

AppDamagedSpoon is the graphical front end for designing ETL workflows for Pentaho Data Integration also known as Kettle. The latest community edition (5.01) was released in November of 2013, with versions for Windows, Linux and Macs. On the first two platforms it works very well as soon as you extract the archive, but unfortunately on Mac OS X 10.9 (Mavericks) there are some issues. It is possible to get it run, but its not easy.

I’ll assume that you have Data Integration downloaded, and extracted on your system and Java 1.6 installed.  The instructions from Pentaho say you can run the Data to launch Kettle, but on the systems I’ve tried this on, I get an error message that the App is damaged. If you are experiencing this, don’t click “Move to Trash!” There is a couple of ways to get it working. 🙂

The first method is pretty straightforward.

  1. While you are clicking on the Data Integration application, hold down the Control key on your keyboard. A menu will appear and you can then click on Open near the top. You’ll then see an Are You Sure warning window, where you can click Open again. The application will then start. Simple!

Install GIMP – Mac OSX

The official GIMP website does not provide installation media for Mac OSX, but thanks to the efforts of Simone Karin Lehmann, an executable is available with a fairly straightforward and simple installation. You can download the install files from

The GIMP on OSX website. The current version is 2.8.0

Before you can install GIMP though, you need to install XQuartz, which is a Mac version of the open source XWindows system. (Basically it provides many of the libraries that GIMP uses to communicate with your hardware.) You’ll get this message if you try to install GIMP without first installing XQuartz. You have been warned. 🙂

  1. Download XQuartz from At the time of this writing, the version was 2.7.2. It’s a 70MB file so the download should be fairly quick.
  2. Once you have it on your Mac, open the DMG file and click on the XQuartz.pkg file. Answer the prompts to install it and take a short breather. It doesn’t take long, and when it’s complete you’ll need to restart your Mac for it to run.
  3. Go to to find the most recent GIMP for Mac install files (2.8.0 at this time). Currently Tiger (10.4), Leopard (10.5), Snow Leopard (10.7) and Lion (10.8) are all supported. At almost 87MB, the download will probably take longer than the installation.
  4. Now that you have the Gimp.dmg file, open it up. You should see a window like this.
  5. Just drag the GIMP icon over to the Program folder and you’re done installing!

Be sure to read the Important Notes document, and if you have time the License and ChangeLog files as well.

GIMP system folder on Mac

If you are running GIMP on a Mac with OS X Snow Leopard or OS X Lion, you may run into this problem sooner or later.

By default, these versions of the Apple operating system hide the user’s Library directory. This is the folder area where different applications store preference files, plugins, etc. The rationale I’ve heard is that this is probably to keep people from accidentally deleting or damaging files that are necessary for OS X Lion to function properly. Fair enough.

But if you want to add plugins or brushes to GIMP, you’ll probably want to make that folder visible in the GUI so you can access it through the Finder. That is much easier than going to the command shell in Terminal every time.

Show User ~/Library in OS X Lion


Start up the Terminal application from Spotlight by opening it up (click the little magnifying glass in the upper right of your screen) or in Finder click on GO and choose Utilities.When the Utilities window opens, double click on Terminal.

In the terminal window enter the following command to show the Library folder:
chflags nohidden ~/Library/

The users Library folder will immediately become visible again. Now you can drag all of those GIMP add-on files to your Library!
