Hi there and welcome Joel
Is this the disk to install your Pixma MG 2500?
The disk your trying to install may have an issue or be for windows, but you can download and install the installation instead.
Use my link below
Click download now, and once the file has been downloaded, run it and perform the installation which will install the printer on the Mac
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know please how you go.
