Use K3b. If it still doesn't work, there's most likely something wrong with the image. Did the checksum check out?

Was the downloaded file corrupted? Check it like this. For example, if it was this one: https://macintoshgarden.org/apps/os-904-us with this md5sum: MD5: 4f26f27ffd15f8eec95db9191b7b3a9e then: 1. Open up the folder it was downloaded to. Right-click > Create Document > Empty File. Name it "correct" without quotes. 2. Then paste whatever the Garden says the MD5 sum should be. In this case, it says 4f26f27ffd15f8eec95db9191b7b3a9e, so paste 4f26f27ffd15f8eec95db9191b7b3a9e in the file. 3. Then save and exit it. I'm using MATE as my desktop environment. So if I right-click in an empty area of the folder, and click "Open in Terminal". It brings up a command prompt. Say the file is "691-2684-A-Mac-OS-904.iso". Then: 1. Type the command: md5sum 691-2684-A-Mac-OS-904.iso 2. It will output something like this: 4f26f27ffd15f8eec95db9191b7b3a9e 691-2684-A-Mac-OS-904.iso 3. Double-click "4f26f27ffd15f8eec95db9191b7b3a9e" and then copy it. The keyboard shortcut to copy it from the terminal window is CTRL+SHIFT+C. Or you could just right-click it and copy the selection. 4. Now that you have the ACTUAL md5 sum, go back to the folder. Make a new file the same way you did before, and name this one "actual" without quotes. Paste your copied md5 sum into the file. Save and exit. 5. Now go back to that command window. Hopefully you left it open. If not, bring it up again the same way you did before. Then type: diff actual correct 6. If there is no output from that command, then that means the file was verified to be intact and not corrupted. If it says something like: 1c1 < 4f26f27ffd15f8eec95db9191b7b3a9e --- > 26a0239aaee8ee6e8383c90928819d2e then that means it was corrupted, and you should download it again from a mirror download.

If the file was good, and it still doesn't boot, then maybe the lens is dirty, or maybe that Mac doesn't recognize ISO 9660 or UDF file systems. When I burned my most recent CD-RW (the Mac OS 7.6.1 version RossDarker made), my Linux computer didn't recognize the image type, but I told it to burn it anyway. It worked on my iMac. Out of curiosity, I looked at what filesystem type was used on the burned CD-RW, and it was ISO 9660. I put the burned CD-RW into my Linux computer's optical drive, and started K3b. I right-clicked on where it says "Complete CD-RW" in the top left, and clicked on Media info.

Some old optical drives seem to have trouble reading disks burned at too high speeds made on modern machines. I've heard this a lot, so I never burn at the highest speeds.

I also try to do that. But the optical drive in my main computer will only burn at 10x for CD-RWs.

What was the result of verifying the checksum for the image? Not much we can help with if it's corrupted. That should be the first thing to check, tbh. Otherwise it doesn't matter how many coasters you burn through, if it's corrupted and the integrity wasn't checked, you're just gonna waste your CD-Rs. It's more than just a ritual. I have downloaded images from the Garden that were corrupted; it happens.
