Making ISO files

Hey guys, this is Mac Kids 101, and today I'm going to be teaching you how to create your own ISO files.

Basically, ISO files are the same formats that CD files are written in. So, for example, if you downloaded Ubuntu from the internet, which is Linux, it would be in an ISO image file.

You're going to need two things: Disk Utility and Terminal. Both of these are free and they come with your Mac, so there shouldn't be any problems.

The first thing you're going to want to do is you're going to want to have a folder that you want to create into an ISO file. All right? So as you can see, I have a folder on my desktop called "Example" with a couple images inside, and I'm going to be making an ISO image of this folder.

So the first thing I'm going to want to do is I'm going to want to open up this utility. All right? Once Disk Utility is open, you're going to go up to File > New Disk Image from Folder, or you can just press Command + Shift + N.

Then, you're going to want to select the folder that you want to make an ISO of, in my case, "Example." All right? Call it whatever you want. As you can see, it says ".DMG." You do not want it to say DMG.

So to change that, you're going to want to go to Image Format and change it to "DVD/CD Master." It's best to keep it not encrypted because if you want to burn it to a CD, then it's not going to work because you can't have an encrypted CD.

So then just click Save, and this will pop up. Just give it some time; basically, it's just creating the .CDR file. So once that is done, you can just quit this utility; we no longer need it.

Now, the next thing you want to do is you're going to want to open up Terminal, and you're going to want to bring Terminal into the directory where you want to save this file. So I'm just going to save it to my desktop.

You can say cd space desktop, and now you can see on CD it's my desktop. So now, the next thing I'm going to do is I'm going to want to convert the .CDR file to a .ISO file.

So to do this, I'll say hdiutil for HDI utility, and you're going to say makehybrid -o. By the way, I'll have this whole thing in the description of the video, so you can just copy and paste it: -joliet -o, then you're going to want to say the name of the ISO, so the name of the thing—the name of what you want your ISO file to be called.

So, I'll say myISOfile.iso. If it's an ISO file, of course it has to be .iso, and then the name of your current files: I'll say example.cdr.

So you can just press Enter, and pretty much we're done! As you can see, I've got my ISO file, the .iso, and if I open that, I can just burn that to a CD. You can see it has all the pictures that I had in my original "Example."

So that's pretty much it! Thank you for watching Mac Kids 101. Enjoy making your ISO files, subscribe, and goodbye!
