How to burn ISO disc images System
Disc images are a fairly common packaging standard for large software programs. If you want to try out a new Linux distribution, for example, chances are you'll need to download a disc image in ISO format and burn it to a blank CD-ROM or DVD.

But ever since I began using Mac OS X, I've been perpetually confused about how to burn ISO images. I'm used to disc burning utilities that have an obvious, explicit command like "Burn ISO Image to CD." To make life even more confusing, OS X's Disk Utility does have a Burn command, but it becomes disabled when you click on the blank disc you'd like to use for the burn.

The problem here is that most Mac disc utilities, including the built-in Disk Utility, take a different approach when it comes to image burning. Instead of telling the program you want to burn an image, then choosing the file, you're supposed to do the reverse: You choose the file, then tell the program you want to burn it. So, to burn an ISO image to disc, here's what to do:
  1. Insert a blank disc.
  2. Start Disk Utility.
  3. From the File menu, choose Open Disk Image and select the ISO to be burned.
  4. In the list of volumes, you will now see an item representing the ISO file. Select it.
  5. Click the Burn button and follow the instructions.
That's it! Sure, it may seem simple enough, but when you've been using Linux and Windows utilities for years, these steps can be a little perplexing and hard to remember.

[robg adds: Yes, for those who've been on the Mac for a long time, this is an obvious hint. However, I've been confused when trying to use Windows and Nero to burn discs, so it seems the opposite would also be true for those new to our platform of choice.]

How to burn ISO disc images
Authored by: t413 on Jun 22, '06 08:20:52AM

Yes, I can confirm this works as I have burned piles of disks using disk utility in this fashion. However, there is an easier way to get the iso you want rather than using File -> Open Disk Image, just drag the image into the left plane and it will show up there with all the other disks mounted or not mounted on your system. You can then highlight it and click burn. If you want to get it out of the sidebar you can drag it out like you do with icons on the dock.

How to burn ISO disc images
Authored by: marroug on Jun 22, '06 08:23:29AM

Thanks for the hint... It's nice to have these "obvious to some, hidden to others" hints. I would just to point out a thought process: If you want to copy/move a file from one folder to another, you select the file, then drag it to the new folder. This is the thought process for burning a CD... you select the file, then "copy" (burn) it to the CD. It would be very strange if you wanted to make acopy of file to another folder, to first select the destination folder then to select the file to copy there. Hopefully this will help others through the mindset....

How to burn ISO disc images
Authored by: tetsuo_ on Jun 22, '06 08:37:33AM

You can do it the other way round, too:

1. Open the ISO image with Disk Utility (e.g. via "Open with" in the finder context menu).

2. Select the image in the drives list in Disk Utility.

3. Hit the "Burn" button and insert a blank CD.

Instead of telling the program you want to burn an image, then choosing the file, you're supposed to do the reverse: You choose the file, then tell the program you want to burn it.

Actually you can do just that. When you first open Disk Utility, none of the disk images will be selected in the disk image list on the left of the screen. As long as none are selected, clicking the burn button causes the 'Open File' pane to come down, you can then select the image you want and it will burn.

One step, exactly what you wanted in the first place.

How to burn ISO disc images
Authored by: peragrin on Jun 22, '06 10:10:45AM

While I agree with you that figuring it how to burn an image the first is tough it's even easier than that.

Say you downloaded an ISO off the web.

1)insert blank disc, exit out of the window that comes up.(I don't remember if you want the disc mounted or not, if no one replies to this I will tell you when I get back to my happy Mac.)

2)Drag ISO to the trash can. For me it becomes the burn button and then burns said ISO.


conversely. create a burn folder copy the items you want burned to it, and repeat the above. When using burn folders the burn button becomes active in finder as well.


i very rarely need to use disk utility. OS X does provide other ways to do some of those tasks. They are not all obvious though.

How to burn bin/cue disc images
Authored by: wm on Jun 23, '06 11:38:01PM
Tiger actually includes the ability to burn .cue/.bin images, although I've never tried to do it. You should be able to do it from the command line with drutil (see the man page for more info--look for the burn verb), and it might also work from the GUI with Disk Utility.

I'm quite curious to know if it works. :-)

Yeah this command line method works. But I always forget command line commands and sometimes you have to tell casual users how to do things. It is a bit counterintuitive how to burn an ISO to a disk.

How [not] to burn ISO disc images
Authored by: n8gray on Jun 22, '06 04:05:47PM

I still can't quite believe it's not:
1. Right-click on .iso file
2. Select "burn image"

That seems like it would be the most obvious way IMHO. I don't know why Apple doesn't make it work like that.

How to modify ISO disc images?
Authored by: lassowitz on Jun 22, '06 07:44:48PM
Does anyone know how to modify a bootable ISO disc image on the Mac? Burning seems fine, but once I try to mount a bootable ISO image to modify its contents, there seems no way to create a new ISO image on the Mac that can then startup a PC.

Specifically, I am trying to create a modified version of the MFS Tools CD (a Linux CD to modify TiVo hard drives) to include my TiVo backup file: "http://mfstools.sourceforge.net/";

Anyone know of a solution?

How to burn ISO disc images
Authored by: megagram on Jun 22, '06 11:44:12PM

I'm sorry but I do believe there is a much simpler method for doing this. Someone please correct me if I'm wrong or if I missed someone else's comment dealing with this:

1: Open Disk Utility
2: Images menu -> Burn.. (or command-B)
3: Select the .iso image in the ensuing dialog (or .dmg file or whatever)
4: Your tray will open. Insert a blank disc. Click "Burn".

If you already have a blank disc in there, it should still work from step 2. Don't know why that option is greyed out for the poster of this hint. Perhaps they shouldn't be selecting the blank disc in the list of discs/images. Just make sure NOTHING is selected prior to step 2. Or, if your .iso file is selected in the sidebar, that's a good start for sure.

As for .bin files. Yeah, Toast, or maybe DiscBlaze?

Hope this helps!

Another hint:
A ISO image is the exact same thing as a Toast image. If you ever have to burn an image created with Toast on Windows, just change the file extension from .toast to .iso.

You, sir, are a lifesaver! Was looking for a way to burn latest Ubuntu distro so that I can finally kill off XP on my Dell laptop (all in a good cause) -- yay, we're now a Linux/OSX household!

Anyway, wasn't obvious to me. Found it helpful and signed up to Hints.

Great forum!

How to burn ISO disc images
Authored by: shmavis on Jan 25, '07 08:36:44AM

I switched to Mac about three years ago now. Obviously it was a different version of OSX, therefore the disk utility was different from what it is now. I also struggled with being able to burn iso disc images with disk utility. I was unable to locate any help at that time and after many hours attempting on my own, I gave up and bought Toast. It is a great program and works great. But it is expensive and the new version of disk utility works just fine for burning image files and its free!:)...well you know what I mean, included. One of the many things I love about OSX is the drag and drop ability. So, with that said you can also opt to keep the disk utility icon in your dock. Then just drag your iso file onto the disk utility icon, it will launch utility and there on the left will be your iso, select it, and click burn, throw your disc in and hit enter.

converting .bin and .cue files to .iso
Authored by: neveragain on Apr 14, '07 03:41:25PM
I couldn't find a burn option on the drutil page. But I did find another application you can download -- bchunk (see http://he.fi/bchunk/) -- which will convert .bin and .cue files to .iso.

Burning from .bin and .cue files directly
Authored by: improbable on Jul 21, '07 11:14:20AM

To burn files in .bin + .cue format, this page pointed me to a free application called simply Burn which can burn them to CD. After dragging it into Applications, just double-click the .cue file of the pair.

I know this isn't quite what this hint is about, but I landed here via google and thought others might too.

How to burn ISO disc images
Authored by: JM Lee on Apr 25, '07 08:04:32PM

Please clarify one thing that I didn't quite get.

I have some files to burn in an ISO CD so that both PC and MAC users can use it.

What I don't quite get from your instruction is: Do I name the folder of the files as .ISO before I click to burn it? If this is wrong, how do I end up getting a .ISO to be selected to burn?

Thanks for any help.

How to burn ISO disc images
Authored by: deeproy on Jan 12, '08 12:10:34PM
I found this at slashdotdash. It is really useful for creating iso files in 10.4 - especially stubborn ones that won't build through disk util:

1. Insert CD/DVD source

2. From the terminal you need to discover the location of your CD-ROM:

$ drutil status

You are looking for the following - Name: /dev/disk1

3. Umount the disk with the following command:

$ diskutil unmountDisk /dev/disk1

4. Create the ISO file with the dd utility:

$ dd if=/dev/disk1 of=file.iso bs=2048

5. Test the ISO image by mounting the iso:

$ hdid file.iso

6. Burn or store the ISO.

To remount the CD, use

$ diskutil mountDisk /dev/disk1

If you need to burn a bootable disk (or one with hidden sectors like say a Windows install disk), replace the command:

$ dd if=/dev/disk1 of=file.iso bs=2048

With

$ dd if=/dev/disk1s0 of=file.iso bs=2048

I've never had this fail on me. But be warned, you can hose a lot with the dd command.

if you don't have Toast then use firestarterFX. It's pretty useful anyway to convert ISO's etc. I followed a link from another forum somewhere so thanks to whoever that was!

How to burn ISO disc images
Authored by: roystonlodge on Feb 09, '08 09:30:08AM
Two points.

  1. Remember, until the Mighty Mouse, standard Mac mice only had one button. The "right click" convention is very new to olde-tyme mac users (and I would wager, Mac developers as well). The olde-type mac convention is the good ol' "click-and-drag".

    Now, correct me if I'm wrong, but can you not simply download the iso, pop in your blank CDR, drag the iso image to the CDR icon, and click "burn"?

    Don't get me wrong here, I'm not trying to mock the "switchers" out there who assume it's more complicated than that because the OS they're used to (Windows) makes it more complicated. After all, the whole reason I found this thread is because I too assumed it would be more complicated (I switched from Mac to PC a few years back due to work requirements, and am only now switching back. I'm having to "re-learn" some of the intuitive functions of the Mac).

    In fact, I haven't tested the "click-and-drag" approach yet because I followed the disk utility method in the first post of this thread.

    Still, I'd be very surprised if the "click-and-drag" method doesn't get the job done. After all, it's the way Macs have worked since 1984.

  2. There's no real such thing as a "bootable cd" in Mac terms. If your CD (or floppy) has a full version of the OS on it, it'll boot. To boot from CD, you have to hold down the "C" key on your keyboard at startup. That's been the convention since at least OS 7.6.1 (that was the first OS I used with a CD rom. Booting from floppy in OS 6 on my Mac Classic didn't even require holding down the "C" key).

ASIDE: Not until this year have I had the opportunity to explain olde-tyme Mac conventions to PC "switchers". I have to say, it feels really nice to be explaining the quirks of my OS to them for a change, rather than having to ask them how to perform the same tasks in Windows.

How to burn ISO disc images
Authored by: toucannyc on Apr 05, '08 01:06:19PM

This hint was a really life saver for me, because I was just dragging and dropping the .iso on the blank CD and clicking burn. (life long mac user) It didn't work and now a have a whole bunch of FreeBSD installer CDs that windows won't boot from... But the cd that was burned using Disk Utility works and a windows boot from it! Now I can remove all Microsoft from my house and make it unix!

How to burn ISO disc images
Authored by: Hadleigh on Jul 20, '08 03:09:38AM

I have an .iso file that I'm trying to burn so I can install the app on another computer. I'm using disk utility as mentioned above however after the disk finishes burning and is inserted into the other other computer all that comes up is an ejectable image containing sub-folders housing a bunch of .rsd files. i am therefore unable to run the program. I'm assuming that the burner is writing all the files as data? Any help would be appreciated.

How to burn ISO disc images
Authored by: bluewater13 on Sep 18, '08 12:21:24AM

Hi..

Very helpful info on using disk utilities to burn the .ISO - and this went swimmingly until the end of the burn when the dialogue box says 'closing session'. The disk util program has now hung at this point for some hours... and no indication that it will ever finish. This also happened earlier today and (again) after some hours I quit from the burn program, but then found I couldn't eject the DVD I had in the drive. Eventually I had to reboot, and the DVD could be ejected during start-up but could not be read when I tried reading it.

Anyone got some idea what might be going wrong, and what I can do to sort this out?

I'm running OSX10.3.9 on an old iMac 1GHz PowerPC with 1.25 GB memory (if this helps).

..or do I copy the .ISO onto an external HDD and move the file to a PC and use MagicISO or somesuch?

Thanks in advance...

Authored by: free99boy on May 10, '09 06:48:01AM

I would like to say "Thanks" to Vocaro for the giving me the answer to the ISO file mystery. I have about 5 DVD's with Linux and Solaris in an ISO form. And they are pretty much worth less than the DVD I wasted on them. Not the OS's on them but the fact that if you don't burn the DVD correctly all you get is the same disk image that you had on your hard drive but now it's burned into a DVD or CD
and totally useless other than for pulling the .jpegs for wallpaper.
I was going to use these disks for ninja stars until I read your post. I don't know why all these links on Google are so run around the answer? You get links for a "Mac ISO burner freeware", I go to it and it's all for Windows!! WTF!!
Anyway thanks. Now just tell me how to install the stuff..d8^{))>

How to burn ISO disc images
Authored by: jcurtis1806 on Mar 05, '10 10:15:33AM

I have found that the easiest way to do this is to use two programs: Disc Utility (DU) and Hand Brake (HB). If you have a collection of .iso files, simply open DU and from the "File" tab, select Open Disk Image. Locate the folder your .iso file is located in and select it. A new Finder window will pop up and provide that .iso in a folder containing usually two sub folders: AUDIO_TS and VIDEO_TS. Now open HB and click the "Source" tab. It will ask you for video files. Find the Finder window containing your .iso sub folders and select the VIDEO_TS folder. Then create a destination you would like your output video file placed. Select the format of video you desire, found on the right column in HB, and select "Start" at the top left.

the best way to burn .ts files ( or to make an original DVD copy of YOUR PERSONNEL DVD's) is to copy them with "mac the ripper" and burn them to dvd with "burn" ( the software called "burn"), it is fast and easy! just make sure you change the format to dvd master, you can also do data and audio cd's and dvd's.

Hi!

Unfortunately this does not work for me (I'm using Lion, 10.7.5). I want to mount an .iso as CD/DVD, which doesn't work, it is always mounted as hard drive (I tried using DAEMON Tools Lite and Disk Utility).
Then i tried to burn it so it would hopefully be recognized as CD/DVD but my Mac only found the CD with the as hard drive mountable .iso on it. Like a visious circle...

Any ideas what else i could/should try? Thanks in advance!

Nicky
