I have tried both Leap and Tumbleweed.

I am attempting to install on an older iMac. This was the 32-bit Intel version, with which I have installed other distros of Linux on before. I have tried creating a USB boot stick with Rufus, which I use all the time to create boot sticks from ISOs, so I think I am good there. When I insert the USB stick, it refuses to boot from it after selecting it. I tried burning the ISO to DVD, and even used that DVD to install on another computer. I tried booting with the DVD on the iMac, and I'm presented with a menu with 2 choices. One is UEFI and the other is BIOS (if I remember correctly, I'm at a different computer currently). The screen doesn't appear to be locked up, as there is a cursor flashing. I am however unable to select either menu option 1 or 2 from the keys at the top of the keyboard or the number pad on the right. All other presses of keys have no response either.

Has anyone installed OpenSuSE specifically on one of these computers, and have any tips for how I can go about successfully getting it on there?

Might help or not. I don't own a imac.

I checked those out, but none seem to match the issue I'm encountering. I know I've installed Slackware and Ubuntu on the same model, but I've previously had issues with Fedora and OpenSuSE if I remember correctly.

Maybe there's a keyboard driver issue - do you have any wired PC keyboards on hand?

Also note Leap won't run on anything 32-bit, it's 64-bit only. Tumbleweed still supports 32-bit though.
