Hi. I would like to install Apple Mac OS X 10.8 Developer Preview 4 into VMWare Workstation 8. I have the official .dmg file. I would like to convert it into .iso file. Any suggestions.

And now for my brilliant college educated plan... Google how to convert a .dmg to .iso.

A .dmg isn't really a disk image, it is more of a "virtual disk", like an .img. If you want to convert it to an .iso or .cdr, a better method is to figure out a way to create a .iso image with the contents of the .dmg. Assuming there are no hidden files or such, there shouldn't be a problem doing so.

You're not supposed to tell him, he's supposed to google it.

Why would someone ask on the forums for help if they already failed to google it?
If someone didn't have any luck googling, it's just as good as telling someone who is struggling on a test to re-read the directions. Maybe they even came here from google!

Also, for .dmg files, you could try either renaming the extension (Which might not work), or, extracting it, and using Folder2Iso to create an .iso file from those images. That might also fail, but it's worth trying.

Le, I'm going to help you, sorry for my le accent. Jk.

WINDOWS:

Okay, go download the free trial of MacDrive: http://www.mediafour.com/products/macdrive
Install it (Obviously >.> <.<)

Open your DMG file through MacDrive (you may need to restart before you can open the DMG file through it.)

Download and install IMGBurn: http://www.imgburn.com/

Open IMGBurn (Obviously)

Click "Create ISO from Disk"

At the top where it says "Host" click and select the DMG you have open in MacDrive.

Change any other preferences, where you want the image, what you want the ISO to be called, etc.

Press the big button at the bottom that says "Start."

Wait for it to rip the image.



Do whatever you want with the image file.

MAC OS X:

Download a program called Burn: http://burn-osx.sourceforge.net/Pages/English/home.html

Right click your DMG file, go to Open With and click Burn.

When burn opens you have 4 Options at the bottom: Mount, Scan..., Save..., and Burn.

Click Save.

It'll bring up a box. Tell Burn to put the ISO where you want it, then, rename it from "PoopFile.dmg" to "PoopFile.iso" and click "Save."

It will turn the DMG file into an ISO file.

Actually, .dmg is usually a compressed ISO. In most scenarios, renaming from .dmg to .iso is enough.

dmg2img.

blech, img. Personal tastes I suppose.

Just use VirtualBox. It can directly mount a .dmg file to the VM.

Actually, in OSX all you need to do is use Disk Utility:

1. Start Disk Utility
2. hit Convert
3. select your DMG
4. click the Convert button
5. in the Image Format selection choose "DVD/CD master"
6. hit Save

It will create a CDR file which is a fully unpacked and raw ISO file, all using the tool that comes with OS X. You can even do it straight from the installation disc if needed. For the purpose of not having to deal with foreign and cross-platform unsupported formats I always do this with DMG files before putting Mac stuff on the FTP. Your method may work just as well, but this is a way without the need to download a third party tool.

Agreed, no need for external programs when it's all built in.

Isn't there a way to do it all in Terminal? Disk Utility is mainly a front end GUI terminal...

Turs out, there could be: http://hints.macworld.com/article.php?s ... 1216314856

No. I would like to do the process in Windows 8 Release Preview as host. I can also have Linux Ubuntu 12.10 Alpha 2 converting the .dmg. However, I don't like VirtualBox, I like VMWare Workstation 8, but then you must have an .iso. Don't know how to use dmg2iso.

Let him get his helpful posts up, especially aas that was a good post, IMO. Althought there are better ways to do it, as told by others already.



Hmm. First of all, I don't think VMWare can run MacOS as host on Windows, but I've never tried. Converting it could be done in many programs, have you tried dmg2iso?

I don't know how to use it! Tried many times and failed!

Not in Mac OS X, but Windows!

UltraISO -> Open DMG -> Find convert somewhere ->Enjoy

It says it is invalid!

MagicISO can do it, I'm not sure if it will install though. OS X has a different way of booting than to "legacy" (or so they say) OSes, depends if VMWare can handle it.

Doesn't work...

Would it be possible to borrow a Mac for this job?

Or...should I assume you've already used that straw...

Considering you've been at this for over two weeks now, isn't it time to just download it from BA? . In ISO and all...
