If you have old Powershot software on your Mac OS 10.6 and want to upgrade the software to the latest and greatest, you don’t have to uninstall anything! The Canon software is neat because it will just update all your older software to the new software! It’s quick and easy.
So I then just put the CD in that came with the camera and it will upgrade the software that is already installed from my last Cannon?
That is correct! You would just want to pop the disc into your CD/DVD drive on your computer and then install! Hope that helps and if you have any other questions or issues you can always Contact Us
