Snow Leopard Compatibility

Dev Programs That Work Fine

Netbeans, Eclipse, Xcode, Simply DB, Ardzip, Viscosity (32 bit kernel mode only)

Installing Java 1.5

Fixing MySQL

The MySQL that was installed for Leopard does not function under Snow Leopard. Here is how to update it:
grab the latest version of macports (if you already have macports, then just run selfupdate):

svn co http://svn.macports.org/repository/macports/trunk/base/ macports

build it

cd macports
./configure
make
sudo make install
sudo /opt/local/bin/port -v selfupdate

Install Mysql5:

sudo port install mysql5
sudo port install mysql5-server
--if this is a fresh install and you need to configure the DB
sudo -u mysql mysql_install_db5

Copy your old MySQL data:

sudo bash
cd /opt/local/var/db/mysql5
rm -rf *
cp -r /usr/local/mysql-5.0.67-osx10.5-x86/data/* .
chown -R _mysql *

Start Mysql5:

cd /opt/local ; sudo /opt/local/lib/mysql5/bin/mysqld_safe &

Set MySQL to launch at system startup:

sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist

Fix MySQL Query Browser and Admin Tool, these both work fine, but need to be told where the new .sock file is (expand the advanced arrow):

/opt/local/var/run/mysql5/mysqld.sock

Fixing Stunnel

The latest openssl and stunnel from macports seems to be a bit broken on snow leopard. You can grab the older version by copying over these files:

openssl, stunnel in /opt/local/bin

libssl.* in /opt/local/lib/
libcrypto.* in /opt/local/lib/

once you've done that if you do an stunnel -version it should have reverted to a previous version

Bugs and Fixes

Get Spotlight to index Thunderbird mail

Show/Hide Hidden Items In Finder

To show and hide hidden items in Finder, run the following commands in Terminal: To show hidden items:

defaults write com.apple.Finder AppleShowAllFiles TRUE
killall Finder

To hide them again:

defaults write com.apple.Finder AppleShowAllFiles FALSE
killall Finder

Automatically get rid of the Print Queue when printing is finished

Symptom: You issue a print job and the print queue for the printer keeps hanging around on your dock
Solution: Right click the print queue and enable "Auto Quit"

Pointers for People Switching From Windows

All the shortcuts are different, deal with it.
Unlike the windows trash can, the mac one has no idea where your files came from, and they can not be automatically restored.
In Windows copying over a folder with another folder of the same names just adds to the existing folder. On the mac it completely replaces it, so be careful when overwriting things.

Terminal Tips

There's a file called '.profile' in your home folder that controls all of your variables etc (like PATH). A typically JAVA configuration might look like this:

alias ll="ls -la"

export MAVEN_HOME=/Applications/maven-1.0.2
export M2_HOME=/Applications/maven-2.0.4
export M2_REPO=~/.m2/repository
export ANT_HOME=/Applications/apache-ant-1.7.0
export PATH=/Applications/TextEdit.app/Contents/MacOS/:$MAVEN_HOME/bin:$M2_HOME/bin:$JAVA_HOME/bin:$ANT_HOME/bin:/usr/local/bin:/usr/local/mysql/bin:$P
ATH
export GWT_HOME=/Applications/gwt-mac-1.4
export GWT_EXTERNAL_BROWSER=firefox
export CATALINA_HOME=/Applications/apache-tomcat-5.5.23
export AXIS_CLASSPATH=/Applications/axis-1_4/lib/axis.jar:/Applications/axis-1_4/lib/commons-discovery-0.2.jar:/Applications/axis-1_4/lib/commons-loggi
ng-1.0.4.jar:/Applications/axis-1_4/lib/jaxrpc.jar:/Applications/axis-1_4/lib/saaj.jar:/Applications/axis-1_4/lib/log4j-1.2.8.jar
test -r /sw/bin/init.sh && . /sw/bin/init.sh

grep for particular files

Just java files in current directory and subdirectories:
grep -r --include="*\.java" "Test" .

Port forward from one local port to another (handy if you want to pretend something like MySQL is running on 3305 and 3306)

sudo ipfw add fwd localhost,3306 tcp from any to any 3305 via lo0

Open a directory in finder

open .

Open a directory in textmate

mate .

Open a file in the application that normally opens it

open test.pdf

Set title to user@hostname: directory. Add the following to your .profile or .bashrc file

PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'

How to slow your internet speed for testing

Tips

To resize a sparse image, make sure it's unmounted then run:

hdiutil resize -size 10g

10g = 10 Gigabytes, but you can specify whatever size you want

To include the Date in your time on the top menu bar. Follow these instructions.
My CD/DVD won't eject. Restart your Mac, and when it starts up again, hold down the mouse key.
Add colour to your ls in terminal by adding this line in your .bashrc file.

alias l='ls -lG'
alias ll='ls -alG'

Add colour to your vi (everybody loves vi) with this .vimrc file. The .vimrc file should exist in your home directory. If it doesn't, create one.
To set the default application that opens for a particular kind of file (eg: open .doc in NeoOffice), right click on a file with the extension and choose 'Get Info'. Under the Open with section choose the program you want to open all files of this type with, then press the Change All button to update this setting.

How to copy a CD or DVD

File Sharing

Click on System Preferences
Click on Sharing
Click on File Sharing
Press the + button under the Shared Folders list and select the folder you want to share
Select Users and Permissions
Close System Preferences screen. This will share folder BUT only for that folder NOT subfolders.
Open Finder and find folder you shared above
Right Click folder and Press "Get Info"
Open Sharing & Permissions
Click Padlock and enter your system password
Make sure privileges are correct
Click on Gear button at bottom and select "Apply to enclosed items"

Screen Sharing

The Screen Sharing application is found under /System/ Library/CoreServices. Do not start yet.
Open up Terminal and run the following command

defaults write com.apple.ScreenSharing 'NSToolbar Configuration ControlToolbar' -dict-add 
'TB Item Identifiers' '(Scale,Control,Share,Curtain,Capture,FullScreen,GetClipboard,SendClipboard,Quality)'

Now when you open up Screen Sharing you will have a few extra buttons on your toolbar.

Developing For The Mac

General

Build a disk image (just like most commercial apps have): instructions

Java

To add your application's menu in the Macintosh Menu Bar, add the following in the VM Options in the Jar Bundler tool.

-Dapple.laf.useScreenMenuBar=true

To set the types of files that your application can handle, edit the Info.plist file (right click on your application, choose show package contents, then go down one directory to where the file is). For example, to set your application to allow any file to be dropped onto it:

<key>CFBundleDocumentTypes</key>
<array>
	<dict>
		<key>CFBundleTypeExtensions</key>
		<array>
			<string>*</string>
		</array>
		<key>CFBundleTypeName</key>
		<string>Generic Document</string>
		<key>CFBundleTypeOSTypes</key>
		<array>
			<string>****</string>
		</array>
		<key>CFBundleTypeRole</key>
		<string>Viewer</string>
	</dict>
</array>

The easiest way to handle mac specific events in your code, is to use the macify library: [1]
To detect whether you're in OS X in JAVA:

public static boolean isOSX(){
    return System.getProperty("os.name").toUpperCase().indexOf("OS X") >=0;
}

If your code needs to run in Java 1.6, you can package it use 'Jar Bundler' for the mac. You may need to add this parameter to your info.plist file to make it work with the preview build of Java 1.6 for the mac:

<key>JVMArchs</key>
<string>x86_64</string>

Making your Java app shine on OS X [2]
Apple Java Extensions API [3]
Using Locales on your Mac. When you want to get the default Locale on your Mac, eg:

System.out.println("Locale="+Locale.getDefault());

You must ensure you select your Language correctly:

- Open System Preferences > International > Language.
- Click 'Edit List' > Check 'Australian English' > OK
- Ensure that 'Australian English' appears at the top of your list of Languages.

Automation

Ruby OSA

RubyOSA is a ruby library that lets you access AppleScript functionality on your mac. This comes in handy when you want to automate systems tasks or interact with applications in a friendly object orientated way, instead of in the weird pseudo code language that is AppleScript.
It's as simple as:

sudo gem install rubyosa

And then you can do things like:

require 'rbosa'
itunes = OSA.app('iTunes')

track = itunes.current_track
p track                     # <OSA::Itunes::FileTrack:0x1495e20>
p track.name                # "Over The Rainbow" 
p track.artist              # "Keith Jarrett" 
p track.duration            # 362.368988037109 
p track.date_added.to_s     # "2006-06-30" 
p track.enabled?            # true

# Play the selected track.
itunes.play                    

# Fade the volume.
100.times { |i| itunes.sound_volume = i; sleep 0.1 }  

# Set iChat's status message to the current track.
OSA.app('iChat').status_message = "Playing: #{track.name}"

To find out what functions a given application has available:

rdoc-osa --name "iTunes" --op DirectoryToStoreDocIn

or for system level things:

rdoc-osa --name "System Events" --op DirectoryToStoreDocIn
