What should you install on Mac OS X when you need to edit existing PDF file?
Well, you can buy or install a trial some program from App Store. You can also install some programs that provide creation of PDF for free. But I do not recommend Skim or Scribus programs to edit existing PDF. They are hard to use.
If it is about a quick PDF fix or edition I recommend a different solution – an installation of OpenOffice extension.
Be careful about what version of the extension you download and if it matches the version of your previously installed OpenOffice or LibreOffice. It does matter.
To install it on Mac OS X you have to:
1) open Programs folder, find OpenOffice and click on it opening context menu,
2) choose Show Package Contents and navigate to: Contents -> share -> extensions -> install,
3) copy/move your fresh downloaded extension file (.oxt) to “install” folder.
4) restart OpenOffice.
Now you can open PDF to edit by clicking: File -> Open from menu and choose .pdf file. Editing PDF now is extremely easy. It is similar to using Open Office Writer.
OpenOffice/LibreOffice PDF extension works very well (tested by me) also on Ubuntu operating system.
