Can I mound a disk image as a "CD" or "DVD"?

I have a lot of games that require the DVD or CD to be played, and they cannot be fooled by making the disc into a DMG then mounting it. It's really annoying for me to keep switching out my discs to play games.
I heard that Toast can mount a disk image as if it were a real CD or DVD, which fools the games, but I don't want to buy it (it's basically Disk Utility for $80 with only one extra feature). Is there a trick to mount a disk image as a "real" disc instead of simply a volume?
And for those wondering, I am not a pirate. Otherwise, I would have pirated Toast already! I'm just sick of switching my discs out.

It looks as if you need 3rd party software for this. From this outside thread:
Toast uses a kernel extension to create a fake optical drive that looks to other software like it's a real optical disc in a real optical drive. The most obvious thing that'd immediately appear different to the casual observer would be that Finder shows a CD icon instead of the disk image icon, but on lower levels it behaves in software just like a real CD, as opposed to a mounted DMG.

How can I create a disk image of snow leopard installer disk from my Imac which runs it?

how can I create a disk image of snow leopard installer disk from my Imac which runs it? It came without DVD installer, and I want to make a copy of it's OS installer but can't find out how.

You need to have the disc in order to create disk image of snow leopard installer disc. What did your machine ship with? If something later than SL, then why? If earlier, then you can buy the SL installer disc and make the disk image.

The error that I am getting is this "Time Machine can't use the disk image because it can't be written to." Any ideas on the fix for this?

The error that I am getting is this "Time Machine can't use the disk image because it can't be written to." Any ideas on the fix for this? When I go to the Time Capsule my Macbook Pro shows that it is locked, I think I did something wrong, but can't figure how to unlock it to see if that fixes it.

As far as we know, Time Machine cannot write to a disk image. It needs to write directly to the Time Capsule disk.

I hate to have to tell you this, but backing-up that way is unreliable and not supported by Apple. See: Using Time Machine with an Airport Extreme Air Disk.
Backup failed with error: The target disk image volume is read-only.
Most likely, you got this message before all this started:
What that doesn't explicity say is, the backups failed the verification. When that happens, Time Machine marks the sparse bundle as damaged and won't back up to it anymore (even if Repair Disk can't find the problem). See #C13 in Time Machine - Troubleshooting for details.

Can I make a DISK IMAGE of the installation DVD as BackUP?

Well after a week of continuing problems, I am so glad that I had several Fully Bootable Backups on external FW800 Hard Drives to keep me alive as my internal HD has been freezing and other repairs may be needed.
The ability to restart via the OPTICAL DRIVE with the original Installation DVD was also a BIG HELP. But, what if my optical drive would go? I am wondering if there is a way to make a copy of the installation drive (I'm thinking of a disk image file - believe Disk Utility can do that??) - But will it be recognized and serve to boot / install Snow Leopard on my Mac should I need it? (MBP-13" mid-2010 issue)
I don't want this for any reason other than emergency backup -- I had a DVD that was scratched and could not be read-- hey, maybe I should burn a copy as well?
Please let me know what is technically and legally possible here. I can't use a snow leopard DVD on this Mac - as it is too new. I need some backup(s).
Thanks!
Best regards,

Modifying, no. That use to be possible in the pre-Tiger past.
And with Mac Pro all you really need is to have a small 20GB partition and put OS X there for use when you want to run Disk Utility you would also be able to use other programs like CCC or Disk Warrior.
I honestly never have had to get out the original DVD (SL, Leopard, OEM) except maybe once. But I have cloned my system and even backed up my small 20GB "edrive." I also use CCC to backup system (80GB or less) to sparse disk images. But I also bought OS X DVD 10.5.6 as I wanted something with driver support for new hardware, the same thing happening now if you install the ATI 5770 and won't be able to boot with less than 10.6.4.
BootCD back in 10.3.x days though could be used not just to add other packages and use the current OS to create DVD, but to have a live DVD and be able to run Firefox and utilites.
Installing OS X off FW drive is fast, fast booting, and 5-10 minutes max to do the install.

Can I do a disk image of my old system before installing Leopard?

On my MacBook Pro, I am thinking of doing a disk image of my entire drive on a 500 Mb external drive, then doing an "Erase and Install" of Leopard, and then doing a Migration Assistant from the external drive, to pull my prefs, files and apps over to the new OS.
Is this a good idea, and if so, how do I duplicate my entire system on my external drive?

Yes you can - in fact it is highly recommended
Most people like either carbon copy cloner (CCC - http://www.bombich.com/software/ccc.html - the one I use) or SuperDuper - http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html - SuperDuper did not have a Leopard version last time I looked although it is not critical since you will do the clone under Tiger
Once I had a good clone, I simply did an upgrade on my external drive (in retrospect it would have made more sense to upgrade the internal drive) and it has been fine
Others have prefered using archive and install
Still Others have done an erase and install and used migration assistant (some have had trouble with that too) and some have moved their data over and reinstalled all their applications (remember iLife is NOT on the Leopard disks so have to be either migrated or reinstalled after an erase and install
My suggestion (certainly NOT universaly agreed to) would be to make your clone, test it and then upgrade your internal drive - after a while (I am still waiting after a month) if all is well you can erase the external and use it for TM - if you have problems then you can either move the clone over to the internal and archive and install or erase and install - and at any time you can boot on the external back to Tiger if you want to or need to

How Can I Transfer My Disk Image to An Identical Macbook Pro?

Hi there,
I'm attempting to make an exact copy of my primary Macbook Pro's Disk Image (we'll call it Computer A) and transfer it to a nearly identical Macbook Pro (Computer B) so that it may function as a backup on the road. I use my computer for musical performance and need to have a backup ready to go in the event of any show-stopping bugs. I need to be able to open Computer B in case my existing one fails.
I've already made a copy of Computer A's entire disk image using SuperDuper! and now need to know what steps I can take to overwrite the hard drive of Computer B with Computer A's disk image, thus making a perfect clone of Computer A.
On Computer A I am running Yosemite 10.10.1 on a 13-inch Mid 2010 Macbook Pro w/ a 2.66 GHz Intel Core 2 Duo and 8 gigs of 1067 MHz DDR3 RAM.
Computer B is a Macbook Pro (Mid 2009) currently running OSX 10.5.8 (as it's old owner fell behind on OS updates) w/ 2.53 GHz Intel Core 2 Duo and 4GB of 1067 MHz DDR3 RAM.
Will the Migration Assistant be able to do what I'm expecting? Are there any potential pitfalls I should look out for? Is Macbook Pro the best community to pitch this question?

You may try SMC and PRAM resets:

If no success, then you have a hardware problem. Make an appointment at an Apple store genius bar for a FREE evaluation.

Disk Utility reports "resource busy" and can't create an disk image

HI,
Just succesfully updated to Mountain Lion on my MBA and iMac. No problems. A very smooth proces.
But, on my iMac the Disk Utility are not able to create new images at all! I'm not sure if this relates directly to the update, as
DU works fine on the MBA.
I have tried to create a simple disk image from a folder, sparse bundle disk images and sparse disk images - with and without encryption.
They al gave this output from DU: "Unable to create "MYDiskImage.sparsebundle." (Resource busy).
I understand from other postings on the web that others have experienced the same message from time to time, but have not seen a fix for it anywhere.
I can see the "disk iamge" in the DU window (left pane) but are not able to locate it with Finder or on the computer anywhere, but are even able to "repair the
disk image with DU, but then there is actually no disk image when trying to locate it. Very strange.
Any help?
The DU log has this info:

Hi Darth,
Thanks for the suggestion. Somehow I managed to solve the issue (the question was posted in July), I think I restarted the computer a couple of times, but it's interesting that you mention Drive Genius and Drive Pulse, as I also had that app running!
Maybe Drive Pulse was also turned of here in my process and helped to solve the issue.
Anyhow, thanks.

I can not open a disk image to install its contents

Disk Image Mounter is missing from my system. Also Disk Utility and Disk Copy both quit in mid start as do a number of third party apps. Also System Preferences tends to lock up when changes are made to certain panes.

Hi PLYNKMac, and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.
May even need to do an Archive and Install if you have room on the HD, but saves all your files and gives a new OS...
http://docs.info.apple.com/article.html?artnum=107120
I only use Software Update to see what is needed, then get them for real via...
http://www.apple.com/support/downloads/
That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing.
If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...
http://docs.info.apple.com/article.html?artnum=107120
Just be sure to select Preserve Users & Settings.

DVDSP3-Can You Make A Disk Image File From DVDSP3?

*Hello again. I'm just finishing up my first go around w/DVDSP3. I was surprised that when I got to the burning options, that there was no option for burning a disk image file. Is it do-able on this program?*
*I burned out one disk and tested it on a couple different players, and "finally" it was good. After the burn, the prompt just said "Formatting finished". There was no option to burn another disk, nor could I find any place to bring up a menu, to tell it that I needed 4 disks. Therefore, it was hours just to get 4-15minute dvds burned, as it started the build all over again each time. Thanks again for the help!*
LarryWest

In the Format - even the Build and Format too - dialog, you have an option to write the disc to the hard drive.
If you need to make a copy at a later date (even after you've nuked everything from your hard drives, you can use Disk Utility in OS X to make a disc image from an existing DVD-R, then burn additional copies.

How can I make a disk image of an unmountable disk?

I have an external La Cie USB 3 disk that refuses to mount. I'd really like to get the data off of it. I recently had another external disk die the clicking death and I found a utility that made a disk image of that disk, but now I cannot find the utility. All I can remember is that it had an odd name.
Any ideas?

Can't create encrypted disk image

With Leopard, I have repeatedly followed the instructions for using Disk Utility to make an encrypted disk. All appears to go well...all fields appropriately filled, including 128 encryption. But when I hit create, either nothing happens, or I get a second Disk Utility starting window. In any case, I am not asked to create a password, and am unable to find any trace of the disk I thought I'd just created. Would welcome your thoughts.

While creating, make sure that it's saved to the desktop so you will know where it is supposed to be, at least.. Was wondering if posssibly you lost them. Look for the named disks in your home folder and in HD on chance they are there somewhere.
I know you went to Help but just making sure you are creating disks this way (below). Everything worked fine for me--
If things still don't work, turn off DU and move to the desktop "com.apple.DiskUtility.plist" in your home folder/library/preferences. A new file will be created when disk utility is turned on again. Deleting plist files don't usually don't solve problems but sometimes they can become corrupted.
Good luck
RM
1 choose File > New > Blank Disk Image.
2 Type a name for the image, and choose where you want to save it.
3 In the Volume Name field, type a name for the volume that appears when you open the disk image.
4 Choose the size of the disk image from the Size pop-up menu.
5 Be sure you choose a size that’s large enough to hold any changes and new documents you might add.
6 Choose an encryption option from the Encryption pop-up menu.
7 Use the default settings for the rest of the options:
8 Choose “Mac OS Extended (Journaled)” from the Volume Format pop-up menu.
9 Choose “Single partition - Apple Partition Map” from the Partitions pop-up menu.
10 Choose “read/write disk image” from the Format pop-up menu.
11 Click Save.
Enter a password, and click OK.
Disk Utility creates the disk image and mounts its volume on your desktop.
Copy the documents you want to protect to the volume.
If you want to erase the original documents so they can’t be recovered, drag them to the Trash and choose Finder > Secure Empty Trash.

Can't create restore disk image

I want to create a restore disk image of my os x hardrive using disk utility. Everytime I try to create the image it says unable to create disk resource busy. Can anyone help me with this?
Thanks,
Matt

Hi carmat06,
first of all: WELCOME TO THE DISCUSSIONS!
How much hard disk space is available? Be aware that MacOS X needs the same amount of hard disk space for a temporary disk image as the final disk image will account for.
You should also create the disk image on a separate drive.
If this answered your question please consider granting some stars: Why reward points?

Can't open .dmg (Disk Images) since 10.4.8

Hi
Since I installed 10.4.8 update I cannot open any .dmg files - including ones that I have previously opened with no problems.
Whenever I try to open one I get a dialogue pop up which says:
"Warning.
The following disk images failed to mount"
It then states the name of the .dmg and says "Reason: Device not configured"
This is exactly the same for every .dmg.
i have repaired permissions, restarted etc.
Any thoughts or fixes?
Thanks
R

Hi guys.
Thanks for the response.
I found the solution on another forum. And everything is working fine now:
Move these files to the Desktop and restart and try a .dmg;
/System/Library/Extension.kextcache
/System/Library/Caches/com.apple.kernalcaches/
I actually had to restart twice as the first restart made a mess of my bluetooth mouse, but after the second everything is fine.
Hope that helps you as well maree
