OS X :: Disk Image Doesn't Offer Lock Capabilities?
Sep 10, 2010
I have a Disk Image that I've password protected, but have come to find out that even though somebody might not be able to get into it, they can still put it in the trash and delete it.
I've read some forums and everybody keeps saying, "Do a Cmd+I and select 'Locked' and that will prevent it from being deleted."
When I do a Cmd+I on the (mounted) Disk Image, there is no "Locked" option, only "Shared".
There is a "Locked" option on the .sparseimage when I do a Cmd+I on that...however, after I "Locked" it, I tried deleting it and the computer was perfectly happy to let me delete it...which kind of goes against the purpose of locking it in the first place.

Apparently, there are two ways to convert disk images in CDR format to ISO format:
1. Rename diskimage.cdr to diskimage.iso
Or
2. hdiutil makehybrid -iso -joliet -o diskimage.iso diskimage.cdr
The first method is really quick while the second method takes quite a long time. Do the two methods yield the same ISO file? In particular, I would like to convert a bootable CDR disk image to an ISO disk image.

I got my imac in November '09 and my caps lock works but the green led does not light always.
The only way i can fix it is remove the batteries
Or disconnect and reconnect the keyboard by clicking on the bluetooth icon
So if apple is not going to fix this bluetooth bug im going to see if apple will refund my money so i can get a wired one.
My friends keyboard does this also and im fed up with this bs...

I figured out that using disk utility is the best method to create a password protected and hidden folder, but i can't seem to find clear instructions on how to do this. I'd like to be able to have a folder that's password protected and hidden if possible. I'd also like to be able to add files and delete files from that folder in the future as well.

I'm attempting to install several PowerMac G5s with the same image. All the PowerMacs are the same vintage, and two of the four seem to work just fine. The other two have the same issue.
I created a model machine that's suitable for cloning: installed and updated all necessary software, configured system settings, and then used Disk utility to copy the model system to a read-only disk image. I then used the Disk Utility application to prepare the system image for deployment by Scanning the Image for Restore.
I then restored the image to hard drives with Disk Utility. I placed in the four HDs in the PowerMacs. Two of the PowerMacs booted without a problem, the other two won't boot to the restored image. I tried holding down Option key when booting, and option to boot to the drive never shows up. Also tried resetting the PRAM, but that didn't work either.
Info:
MacBook, Xserve G5, PowerMac G5, Mac OS X (10.5.8)

Haven't had any success searching for an answer.
I have an aluminum macbook (April 2009) and when I use a picture as a desk top image, even HD resolution pics it never quite fits well as wallpaper. I have tried all options (stretch, full screen, etc).
When I had windows pics would always fit nicely. With my mac its either too stretched and just doesn't fit well
Anyone else have this issue? Am I missing something?

I'm having trouble printing my images at 100%. For some reason that I haven't been able to troubleshoot, when I try to print an image from iPhoto, I lose a half inch or more of the photo around the edges. It even reflects that this will happen in the preview screen.

I really need to scan some images into my computer and I can't afford the $39 for VueScan. Image Capture used to work, but now what happens is that I open it up, and my printer/scanner Might show up for a second, but then it disappears and image capture tells me that there's no camera or scanner connected.I think it's stopped working ever since I upgraded to 10.6. Any ideas?

My idiot teenage son left his retail disks somewhere two states away in his dorm room. I am upgradings his hard drive from a 40 gig to a 160gig in his ibook. We are visiting family so I don't have acess to my disk either. Can I copy his drive to a dvd, and then copy it over after I install the new hard drive? I've done this before, but never with a dvd or cd.
He is running 10.5.8.

I have downloaded & installed Firefox but can't get rid of the disk image. I've tried dragging it to the bin but every time I use Firefox it re-appears.

I have some files that I occasionally send to my family members. The thing is, because they contain sensitive information (finance records, sometimes they're family videos), I don't like just uploading it to my iDisk.
What I've been doing is going into Disk Utility, creating a password-protected disk image, then zipping up that file. It's a few layers of security, and the 128-bit encryption seems good. The thing is, I'm not sure what settings to use.
Here's a screenshot of the window that comes up when creating a new disk image. What options should I choose from here? I can do a Get Info on all of the files I'm putting in the disk image, but it would be easier to have it auto-fit whatever I put in, eliminating any unused space. I'm not sure of what to put for Format, Partitions, and Image Format, and I'm surprised that I have to choose a size since I've heard there's a way to have it automatically fit the files.
Is there a way to select my files/folders in the Finder and have a disk image created from the selection?

I'm making a "backup" of the first season of House and I came upon the below menu from Disk Utility.
What's the best format to use? I don't really care too much about how long it takes.
Should I use encryption? If so, which form?

I recently was having some problems with iTunes, (it was resetting and erasing the library every time i started it) so i decided to just save my mp3 files to my external hard drive and delete iTunes. My plan was to simply download iTunes again and put all my files back onto it.
However, when i downloaded iTunes, the disk image that apple gives you to set it up failed to mount. The reason, apparently, was because it was "Not Recognized"
I had no idea that an apple computer would not recognize one of the most common apple applications, but there you have it.

I have a belgian azerty keyboard and OS X in english on my white macbook. Is it possible to change the caps lock key's function to shift lock so that it affects the whole keyboard rather than just the letters? I'd like to be able to type numbers without holding shift.

I am currently using OSX 10.5.8 Leopard and have run into a problem. When ever I attempt to mount a .DMG file, Finder goes unresponsive and will not re launch. The .DMG is downloaded from a verified clean source and the default program to open is the Disk Image Mounter Utility. I try going to /System/Library/Core Services, and I see the Disk Image Mounter Utility listed, yet when I attempt to open it, nothing happens and it is not even listed in the activity monitor. I have tried mounting several .DMG files and each time the same problem occurs and can only be solved by rebooting the system. I have just recently tried updating my software to the latest version and still no fix.

I'd like to save individual disc images of the OSX and Win 7 installs on two partitions on my drive so that I can restore the operating systems if I need to. How can I do this since both have different file systems? Do I use Carbon Cloner? How do I restore the Windows partition if I do this?
Also:
I installed Windows 7 32-bit Home edition on a 200gb partition using Bootcamp. I am installing and tweaking the Windows installation and would like to take a snapshot of the system after I have installed all programs and settings.

This is mainly just one of those 'I always wondered' things. How secure really is the 128-bit encryption offered in Disk Utility? Is it virtually impossible to crack? Somewhat difficult? How long would it take someone who really knew what they were doing? If anybody wants to try, I made a sample encrypted disk image. See if you can get into it. Its 2MB and you can download it here. After downloading, you'll have to take the .txt off the end of the filename so its just challenge.sparseimage.

I have all my OS X applications that come with your mac on a seperate .dmg file, that's just how it happened. I'm not sure how it happened, but when I took my computer home, it just installed like that. I bought the iMac ex-display from PC World last august and it didn't come with any documentation, reboot disks or an apple remote. They say they don't have them with them, but they obviously do.
I keep forgetting to mount the .dmg every time I reboot, because I'm a klutz and becoming old at a young age. I was wondering if there's any way to automatically have the mac mount the disk image?

When I download a program or application, can I drag the disk image to the trash and eject the installer. This is an incredibly noob question, I know.
I just always end up with these random duplicate files and I can't figure out what I am doing wrong.

I recently had some issues with my Mac Book Pro and I had to delete my entire Hard Drive. Using Disk Utility I backed it up first by taking a disk image of it all. I fixed my computer and now I am trying to work out how I can re-install my Hard Drive.
I open up the disk image, which takes hours to verify because there is so much stuff on it, and all my stuff is there. However, it doesn't update my computer to be how it was before and also it doesn't stay there, acting more like an external drive, so when I turn off my computer and then on again I need to go through the whole verification process.
How to use this disk image to go back to how my computer was set up?
