A new tutorial titled how to open a file with a different program on your mac was added by Lawrence Abrams. Please use this topic to discuss any aspect of this tutorial.
A brief excerpt of the tutorial can be found here:
When you double-click a file on your Mac, the operating system will automatically open the file using the program assigned to that type of file. It is possible, though, to open the file using another program if you wish. To open a file on your Mac using a different program, navigate to the file you wish to open and right-click on it to see the file menu as shown below.
We hope you find this tutorial helpful.
