Eclipse sandboxed by Mac OS X Gatekeeper.
After I recently reinstalled my MacBook Air with Mac OS X Mavericks, I encountered for the first time Gatekeeper – the sandbox, that won’t allow to run applications from unverified sources to improve Mac OS X security. However that also excludes the commonly used IDE Eclipse.
Problem: Eclipse (or other application) won’t launch in Mac OS X Mavericks.
Solution: delete extended quarantine attribute – which probably Safari or Finder added after the download. Enter the following command in the Terminal to allow Eclipse to launch.
$ xattr -d com.apple.quarantine eclipse.app
This way you can leave the sandbox in place and only add exceptions for applications, that you cannot live without. For further information on and graphical configuration options of Gatekeeper check out this Ars Technica article.
Apple’s annual Worldwide Developers Conference is an exciting event providing an in-depth and inside look at the latest in iOS and OS X. Tickets are always high in demand and have sold out within two hours this year. In addition to the regular tickets, which sold for $1599, Apple accepted applications for one of 150 scholarships.
I have been very excited all day when I received an email from Apple granting me a scholarship to attend WWDC 2012. Thank you, Apple!

iChem is a case study to bring aquatic chemistry calculations on the iPhone to the classroom. The computational nature of aquatic chemistry lends itself well to the iPhone platform and by providing students with a simple means of performing laborious calculations, the underlying chemistry of the problem being studied can be the primary focus rather than the calculations.
The application features Activity Coefficient, Ionization Fraction and Equilibrium Constant computations. The goal is to provide a user friendly tool for chemistry students, which enables them to quickly solve standard computations on their fingertips. The tool will be made available to the public, soon.

My favourite presentation during this event was “Sal on Automation” with system wide services. His website contains very valuable resources on automation Tasks with Mac OS X. Check out:
Recently my SonyEricsson cellphone broke and I wanted to replace it by my Bluetooth enabled Motorola C390. Apple’s iSync is really great to keep your address book and calendar in sync with your cellphone. Unfortunately the C390 is not supported by default. Your Mac can pair with the phone and use it for data connections but iSync does not support it, see .
There seem to be some commercial solutions which may help, though I didn’t test one of them, just search the web for iSync and C390 and you will find them.
Luckily I also found this guy’s Howto in a forum about adding Motorola C390 support to iSync for free just by modifying a xml file . However, since I am running Mac OS X 10.4.9, I recognized slight changes in the xml tag names. That’s why I noted the instructions below.
Enabling Motorola C390 for iSync
- Right click on the iSync Application
- Show Package Contents
- Goto Contents/Plugins/ApplePhoneConduit.syncdevice/Contents/ Plugins/PhoneModelsSync.phoneplugin/Contents/ Resources
- Backup and modify the MetaClasses.plist file to make it look like below in the beginning
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<string>"Motorola CE, Copyright 2000"+C390</string>
- You will need a tiff file, with the name you entered under ModelIcon, but you can just copy it from another one in the same folder as the MetaClasses.plist file
- Start iSync
- Select Devices->Add Device from the menu
- et voilà, your Motorola C390 should show up as a supported phone
I synced my address book and calendar successfully with it, so I don’t know, why the phone is not supported by default. Anyways, use at your own risk.
I have this 2005 12″ PowerBook G4 with Mac OS X Tiger 10.4.9 and was jealous of the new MacBooks’ Remote Controls. One day I found a movie on youtube about someone controlling Front Row with a Wiimote. I just didn’t find all the links in one place. Maybe this is of help for you. It should work on other Bluetooth enabled Macintosh computers as well.
1. Get Front Row to work on a Mac without Remote Control
2. Install DarwiinRemote
- Get DarwiinRemote
- The key mapping matches the one of Front Row by default, though, you might want to change the Wiimote’s + and – buttons to change volume control as well
Works like a charme.
You can also use the Wiimote with DarwiinRemote to go through your PowerPoint Presentations 🙂
When I tried to compile Xerces-C++ Version 2.6.0 from source on Mac OS X Tiger 10.4.2 with gcc-4.0.0 the compiler complained:
MacOSUnicodeConverter.cpp:78: error: 'static' may not be used when defining
(as opposed to declaring) a static data member
MacOSUnicodeConverter.cpp:84: error: 'static' may not be used when defining
(as opposed to declaring) a static data member
make: *** [MacOSUnicodeConverter.o] Error 1
make: *** [transcoders] Error 2
make: *** [Util] Error 2
The solution is easy, just delete the word static in the source code manually and build again or use this patch:
Download the Xerces-C++ source distribution from .
The sources contained in my case version 2.6.0.
Extract sources and apply patch:
tar xzf xerces-c-current.tar.gz
patch -p1 <../xerces-c-src_2_6_0-tiger.diff
Please make sure that the paths are adjusted to your system. Follow the official build instructions Building Xerces-C++ from the Mac OS X command line at  afterwards.
