Please note that I am not responsible for Macuim’s development, it is a separate project that uses m17n-lib which I made a script(si-singlish.mim) for supporting RSinglish scheme on Linux, the latest package that I tested(MacUIM-0.6.15-2) have si-singlish.mim packaged with it. I only bear the maintainence of si-singlish.mim.
Lets get started!
1. Download Macuim from their google project page. You should look for the lastest stable version and should only use a deprecated version if your OS version does not support it; i.e. if you are using Mac OS X 10.4 you’ll have to use MacUIM-0.5.3-1 or otherwise upgrade your OS version and install the latest package. This older package dates back to April of 2009, there’s no way this package will contain si-singlish.mim by default so you’ll have to add it after installation. The information for this will be listed below.

2. Install the dmg like you’d normally do, logout and login.
For Mac OS X 10.5 and higher: Just continue to step 4.
For Mac OS X 10.4: We have to install si-singlish.mim, grab it from here open Finder, goto Computer > Macintosh > Library > M17NLib > share > m17n and paste singlish.mim there.
And run this command on the terminal,
sudo /Library/Frameworks/UIM.framework/Versions//bin/uim-module-manager --register m17nlib
More information about installing a new mim script is here.
4. Go to System Preferences > Language and Text (might be International in 10.4) go to Input Sources tab and select MacUIM and select MacUIM(Roman). Use the shortcut keys or the Input menu in the menu bar to switch in to MacUIM Roman.
5. Go to MacUIM Roman’s preferences as shown below. Make the helper applet display and set hot keys as needed, in my setup ctrl+space is the input method switcher this switches input method inside MacUIM and you have to set alternative input method to another input method(such as direct) to use it.
