The only CD/DVD burners are in machines that only run OS X. For the most part that does not matter all that much for CDs and DVDs are obsolete as floppies. Of course from time to time I have need of burning a CD/DVD. In particular I am trying to burn a Linux ISO DVD image. OS X has disk burning built in, but it is mostly just for file copy stuff and an ISO image can only be burned if the ISO is mounted.

Long story short does anyone know of software to burn an iso disk image on OS X. And perhaps a bit related does anyone happen to know if SheepShaver/Baslisk can use disk burning software and burner in emulation?

Hah! I'm really glad that for once I'll be able to offer help to wove - and not the other way around ;-)

You may want to look for good ol' Toast over at the Mac Garden. Here is Toast 12. Depending on your version of OS X, you'll find earlier or later versions that should do the trick.

Of course, I'm assuming by OS X you're refering to the older OS versions (Intel days) when it was still called OS X and not re-branded Mac OS (like Big Sur on a M1 Mac or something)

I had thought of Toast, but for whatever peculiarities drive me, I just never liked Toast. I remembered using something on my old PM G5 and looked up what it was. I was using Disco, which is also on the Garden. I had purchased it as part of some bundle.

The Garden lists it as working from 10.4 through 10.6, but I put it on 10.7 and it works just fine. It is a really easy drag and drop utility, I am not sure what if any options it might have, but if you drop and iso file on it, it will reliably burn it to disk. Overall that is all I ever used a burner for anyway.

Back in the early 00s few systems were booting from USB and installing an OS entailed using a CD/DVD. I have a good size pile of Linux install CDs that were burned from an iso. I did use Toast with classic Mac OS, but I switched to Disco with OS X.

The original Intel Macbook Pros were core duo machines and hence 32bit, but 6 months after introduction Apple made a spec boost and went to core2duos which were 64bit. But Apple being Apple they left the efi bootloader as 32bit. That worked fine for Apple, but very few Linux distros used 32bit efi on 64bit systems. The upshot being that to install Linux on the first core2duo Macs you need to use a CD/DVD to install. (You can also create a 32bit efi on your own to boot, but that is well beyond my pay grade.)

Don’t all Mac from 2005 have cd-burners in built, I’m sure my Mac mini did and my intel imac does too. So just drag on to a blank disc in finder, no?

When you do this in via the Finder, it just copies the file to the disc. In the case of an iso or dmg you end up with an iso file copy on the CD. What one generally wants to do with an iso or a dmg, is create a bootable CD/DVD of that iso/dmg. In order to do that one needs to use a software application to do that. Toast is pretty common, but MacOS X's Disk Utility can also create a bootable CD/DVD from an iso/dmg.

@wove: Hi. Use the OS X "Disk Utility" to burn images to CD/DVD in OS X.

Make sure the image to be burned is locked (if it was ever mounted on an OS X desktop unlocked - start again from scratch).

Do not mount the image onto the desktop.

Start Disk Utility.

Drag the locked disk image into the lower left side of the Disk Utility Window. Its name will appear in the lower left portion of the window.

Select to highlight the name of the image you wish to burn and click the "Burn" button (or select Burn from Disk Utility's "Images" menu, or type "Command B").

Follow the prompts that occur and have a CD or DVD blank ready to insert when prompted.

@MTT Just our of curiosity does the same advice hold for "burning" a dmg/iso to a USB thumb drive?

@wove: Only the make sure your image is locked at all times and never allowed to mount onto a Mac's desktop unlocked, part. Oh, and drag image into the lower left side of the Disk Utility window too, of course.

With USB you need to use the "Restore" feature - The Burn option in the Disk Utility relates to CD/DVD media only (Burn expects and only knows about the on-board CD/DVD burner).
