How can I convert my CV to PDF on my MacBook?

"I am trying to convert my CV into a PDF file: I have tried to change the CV by using Command and I but that did not work, I tried using adobe but found it confusing and was not sure on which one to pick. I kept getting messages that the file was an invalid extension on MacBook when I tried to convert it, also when I tried adobe I kept getting error messages. Please can someone help me?"

Safe a File in PDF:

To save a file as a PDF document, you'd print this as a PDF document. As and example, here is how to do so in Safari.

1. Go to: File Menu
2. Select: Print...
3. Click: "V" at PDF on the bottom left corner of the window
4. Select: Save to DPF
5. Choose: the location
6. Click: Save button
7. Open the Document.

You cannot change a file's format to PDF simply by changing the file extension.

Normally the way you would generate a PDF file is by doing a print to PDF, or, in some programs by doing an export to PDF.

I am not certain what you mean by "my CV". Assuming it is a document of some kind, what program did you use to create it? If you don't know, open that document as though you were going to edit it and describe what is adjacent to the  (Apple) menu at the upper left of your Mac's menu bar.

I believe that by CV, the OP means a curriculum vitae – which is just a fancy name for a long version of a resume.

Thought so... in other words, "a document."
