Hi John, and welcome to the Debian community! I assume you have a broadband Internet connection where you will be doing this installation? If so:
You’ll want the Mac specific “netinst” installer image[1] that gets most of its software packages from the Debian mirrors on the Web. [1] https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/> Take a look at this wiki page[2] for instructions on making a dual-boot MacOS/Debian setup. The wiki page is aimed at the mac mini but it should mostly carry over for your iMac. Also, you’ll want to read the wiki page[3] for burning an installer CD under MacOS. [2] https://wiki.debian.org/MacMiniIntel [3] https://www.debian.org/CD/faq/#record-mac And, of course, you’ll want to RTFM[4] [4] https://www.debian.org/doc/ If you’re not already signed up, you will want to join the debian-user mailing list[5]. That’s where you’ll find lots of friendly, helpful and knowledgeable folks. [5] https://lists.debian.org/debian-user/ Enjoy!
