I think the Linux one should work on mac, but I haven't been able to test it...my sister wont let me install ff on her mac and test it.
I am currently working on adding icon support for apps, but I haven't been able to add it yet to windows, just the launcher.

EDIT: actually new version, this one lets people toggle/hide/unhide the launcher. I also added a functon to allow someone to hide any object, same with unhiding it. randomInt(a,b) was added from the jBasic library, same with rand() which returns false or true randomly.
Icons are supported now, on both versions, if you make your own app you should make a icon.png that is square and 10x10 or bigger and place it in your apps main folder.

w00t made a program for this that lets you open/close the start menu by pressing `.  Not bad for never using java until now
function KeyHook_open(){
KeyHook_hold = null;
if (TASKER_TASK_LIST.name.indexOf("KeyHook")!=-1){
event_notify('Task already exists');
}else{
tasker_create_task('KeyHook','KeyHook_hook()',null,2);
}
}
function KeyHook_hook(){
if ( keyboard_getKey(192) && KeyHook_hold == null ){
if (launcher.childNodes[1].style.visibility == 'hidden'){
desktop_launcher_open();
}else{
desktop_launcher_close();
}
setTimeout('KeyHook_Off();',10);
KeyHook_hold = 1;
}

}
function KeyHook_Off(){
if(!keyboard_getKey(192)){
  KeyHook_hold = null;
}else{
  setTimeout('KeyHook_Off();',100);
}
}

I wrote a few (1 or 2) more apps for this, and made the MouseHook automaticly loaded at startup.  I also added a feature where when you hover of the clock (or the launcher icon) it opens it (for the launcher icon, it toggles the menu being open).  Check it out if you have time

note: this will not probably not work just taking the apps over, I added a lot of stuff to it (added, modded, same thing

Edit: this is  the linux version btw, will not work in windows

well...I've made:
AB-press Enter and it makes over 9000 buttons...well it continues to make buttons.
KeyHook-press ` to open/close the main menu
JBasicA-a demo of how to use JBasic with jBOS
gui-an app I was working on to make a gui similar to gedit
MouseHook-an app I made to where you hover over the main menu icon, and it opens it, closes it when you rehover it.  It also used to be incharge of the clock thing (where you hover over it and it shows the system time/date) but I've fixed that now because it was messing up on larger resolutions

I've also modded the kernal app (or maybe the window.js one) to include a startup routine, and threw a few folders for testing purposes in the root/home folder.  Oh and I changed the main menu icon, as well as the alert icon

If you have left it running long enough, you will notice that it will have updated! you will have a system clock

I was thinking of going in and adding that.  Eeems, you want to get this one, or can I try it?

here are some routines, file_wline and file_rline (write/read line).  They will write/read to a specific line in jBOS of a file.  Thanks to KermM for the main code for each   Now its time to write some programs to add in my mods to jBOS    jk.  Anyways, here ya go.
function file_rline(path,line){
    file = file_read(path);
    lines = file.replace(/(\r\n|\r|\n)/g, '\n').split('\n');
    return lines[line];
}function file_wline(path,line,content){
    file = file_read(path);
    lines = file.replace(/(\r\n|\r|\n)/g, '\n').split('\n');
    lines[line] = content;
    file = lines.join("\n");
    file_create(path,file);
}(btw, I threw these in at the bottom of file.js)
