    I'm interested in creating applications for Mac OSX, like a text editor or a web browser. Whats the best method to start learning how to do this? What tools do I need? What languages should I learn?

    First, search this forum for the word 'started' and you'll find that this question has been answered, many times.

    On your DVD (or CDs) that came with your Mac the development tools of choice are available. That would be Xcode. The language of choice is Objective-C.

    Most people suggest the best book is Cocoa Programming for Mac OS X by Aaron Hillegass.

    So you buy that book, install Xcode and start learning. I'm not sure the Mac community needs another text editor or browser though.

    You'll also want to get a free ADC membership on the Apple Developer site. They have tutorials and many mailing lists. www.cocoadevcentral.com has some great tutorials and some 'getting started' type ones too.

    I have an application in the Developer file called 'Xcode', so I'm guessing its already installed...

    Also, I made a simple text editor but when I build it, it says
    "SDK package /Developer/SDKs/MacOSX10.4u.sdk does not exist"

    I dont know how to fix this error! Any ideas?

    Maybe you could subscribe to the Xcode-users Help list?

    Just a side question: Is it possible to create Mac OSX applications with C++?

    I know that you can write C++ code, but I don't know (or care) how well it is integrated with the Cocoa frameworks, but people do what you are speculating.

    Not knowing how, when, or what versions are involved, I personally can't answer this question.

    Do a "ls /Developer/SDKs/" in the terminal to see what is in that directory. I have these two directories;

    MacOSX10.3.9.sdk
    MacOSX10.4u.sdk

    I'm running OS X 10.4.10 and Xcode 2.4.1 which I downloaded from my ADC account. It was a very large download.

    Maybe you can try to just reinstall the developer tools.

    Thanks xstep!
    I did what you said in the terminal but it said "no such files found", or something like that. So, I guess I dont have either one installed.

    Do you know where I can get these?

    If they are not there and you have the dev tools installed, then I don't know the answer. Try removing the dev tools and reinstalling them. I don't know what else to say.

    On my first DVD of the install disks there is a folder called "Xcode Tools". Open that folder and double click on "Xcode Tools.mpkg". You should probably read the PDF in that folder too.

    Based on your Mac specs listed under your username, I'm assuming you have OS X 10.4 DVD install disks.

    You're welcome.

    And now you are on your way to creating that next great editor.
