Changing a file format on Mac is typically quite easy. Depending on the specific application you are using, there may be slight variations in how to change the format of your file. However, generally speaking, you can use the following steps to convert a file from one format to another:
1. Open the document or image you wish to convert in its native program (e.g., Pages for documents).
2. Go to File > Export as and select your desired output format (e.g., PDF).
3. Click “Save” and select a destination folder where you want the converted version stored; then click “Export” or “OK” depending on which option appears when doing this step with your chosen application.
4. You should now have two versions of that same document saved — one in its original form and one converted into whatever new file type was selected at Step 2 above!
