Passwording a floder using Disk Utility
I'v gone through the recommended way of creating an image from a folder and giving it a password.
All goes well until I go to open it.
I click on the dmg file, the disk mounts on the desktop and then I can open it and see all my files BUT it never asks me for the password.
Any iitial thoughts as to why this might happen?
(I have used my admin password to keep things simple and it's 6 characters long)
When you create an encrypted disk image, there's a checkbox to store/remember the password in your keychain. If checked, the password is stored and not required to access the files (they are still encrypted when you are logged out). You can either create a new disk image and ensure that box is UNchecked, then copy your files there and delete the old disk image, or you can use the Keychain Access utility to manually delete that keychain entry. Note that if the password is not stored in the keychain, the 'remember password' checkbox is present each time you open the disk image, and you should NOT check the box.

The difference between a .dmg file & a .cdr file (using Disk Utility) ?
Hi,
In particular, I created both from a DVD using Disk Utility.
When I chose "read only" a .dmg was created.
When I chose "DVD/CD Master" a .cdr was created.
They are exactly the same size.
Is there any difference ?
Thanks in advance.
Pat De MarcoHI Pat,
From Wikipedia: A file with the extension .dmg (an abbreviation for disk image) uses a disk image format commonly found on Mac OS X. The format allows secure password protection as well as file compression and hence serves both security and file distribution functions. Its most common function is the distribution of software over the Internet. When opened, DMG files are "mounted" as a drive within the Finder.
From: Wikipedia .cdr and ISO
ISO image
Filename extension .iso
Uniform Type Identifier public.iso-image
Type of format Disk image
Standard(s) ISO 9660
An ISO image is an archive file (a.k.a. disk image) of an optical disc using a conventional ISO (International Organization for Standardization) format that is supported by many software vendors. ISO image files typically have a file extension of .ISO but Mac OS X ISO images often have the extension .CDR. The name "ISO" is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain UDF file system because UDF is backward-compatible to ISO 9660.

Does Time Machine utilize the password I created in Disk Utility?
Using Disk Utility, I created a volume (confidential.dmg) which contains personal information. Within Disk Utility, I also elected to require a password to open this volume.
Using Time Machine, I back-up the entire contents of my Mac to a fire wire drive.
If someone had possession of my fire wire drive, would they have to know the password I created in order to open confidential.dmg? Or are there other ways someone else could access the contents of confidential.dmg?
ThanksTime Machine will just back up the encrypted disk image so yes, if somebody had access to your Time Machine they'd still need to know the password if they wanted to open it.

Understanding encryption using Disk Utility
Using Disk Utility, I created an encrypted disk image, into which I have copied files I would like to secure. This works well, but I am trying to understand how things work, so that I can control exposure. Fundamentally, the question is when are files exposed, and when not. Clearly, when a password has been entered, the file is visible and available. But is it being decoded (ie is the underlying file is always encrypted)? If I make a copy of a file (after password entered), is this copy encrypted? If I make a back-up using Time Machine, are the back-up files (of encrypted files) encrypted?
Tony T1 wrote:
What I think he means is, if the Volume is backed up to Time Machine, it won't be encrypted, but a mounted Volume from a Disk Image is not backed up to Time Machine, so I'm not sure what he means. The actual Disk Image (that is backed up to TM) is always encrypted.
Yes, sorry, what I wrote was misleading:
When an encrypted volume (an actual disk partition or a disk image) is backed-up, the data is decrypted. It's only re-encrypted if the destination is encrypted. So if you use FileVault2, your backups of normal items will not be encrypted if they go to an unencrypted disk. But, they will be encrypted if they go to an encrypted disk or disk image.
The contents of a disk image are backed-up only when it's not mounted. If it's mounted, the disk image will appear in the backup, but the contents will not have changed. -
How do you use disk utility to burn a bootable .iso dvd?
Anybody have a clue on how you use disk utility to burn a .iso bootable dvd disk?
I'm trying to install windows 7 rc into virtual box in OS X 10.5.7 and cannot figure out how to do this. I've already installed the windows 7 beta in virtual box and was able to make a bootable dvd disk with the .iso file on it but have no clue how I did this.
I've been searching the web but most tips are for older version of OS X.
Thanks to anybody who answers.It's so easy, You can just burn an .iso file using DVD Creator Std instead of Disk Utility, only 3 steps to finish bur ning your .iso files:

Hi,
I'm looking to upgrade from Snow Leapord (10.6.8) to the new Mountain Lion. Have a lot of applications and softwares that I would like to back up when installing the new OS, such as MS Office, Adobe Photoshop and Illustrator. Any ideas on what is the best way to do that.
I'm not too tech savvy, so a simple solution would be appreciated.
Thanks,
ShyamIf your not very tech savvy, I would have someone assist you in the upgrade process as your about to inflict major change on your life and computer.
There are some things to consider before you upgrade.
1: The age of your machine:
My advice has been if your Mac is less than two years old and has a dedicated graphics (not all only Intel HD 3000 or 4000 CPU graphics like the 13" has)) then you stand a very good chance of 10.8 (or 10.7) running fine on your machine.
In either case you need to check the specifications of your machine to see if it meets Apple's requirements, and unfortunately those requirements are a bit low, resulting in a slower machine when you upgrade.
https://en.wikipedia.org/wiki/OS_X_Mountain_Lion
https://en.wikipedia.org/wiki/Mac_OS_X_Lion
(note: 10.7 is no longer being sold via the AppStore, you should upgrade to 10.8, however some machines can't, you can call Apple Sales to upgrade to 10.7)
If your machine originally came with 10.5, I would say forget it. Mac's don't last forever and laptops usually have a life of about 4 years with normal use. Desktops last longer of course and can withstand more OS X upgrades if Apple allows it.
2: The age of your software.
10.7 and 10.8 will not run PPC based software of old like 10.6 does, also upgrading to 10.8/10.7 may require expensive software upgrades that can hit you unexpected. Consult this site and your other needed software and hardware drivers/software (for printers/scanners,custom keyboards/mice etc) BEFORE you upgrade the operating system.
http://roaringapps.com/apps:table
3: Carbon Copy Cloner or SuperDuper "clone" (payware)
Your OS X boot partition to a new/reliable, blank powered external drive and use Disk Utility to Repair Permissions on both afterwards. You can hold the option key down and boot from this clone drive to use the computer like before if your OS X upgrade fails and the machine gets bricked. You can also use Disk Utility to erase the entire internal drive and reverse clone if you find out the OS X upgrade is not to your liking.
Make sure all other drives are disconnected, like TimeMachine when cloning or upgrading OS X, thus when you reboot TimeMachine doesn't self update itself, which can lock you out from going back in time to restore from.
Note: If you have Bootcamp, you can clone that with WinClone (payware) to another drive and recreate Bootcamp later and restore it.
4: Some firmware updates can possibly "BRICK" your hardware
Firmware updates progress in a forward manner and can't be downgraded, so what sometimes occurs is a software error by programmers or a hardware glitch on your machine won't 100% cooperate with the firmware update and thus your machine will fail to function. Sometimes even a interruption in the OS X upgrade or firmware update process will cause the problem. When this occurs, a trip to a Apple Repair is in order and if your machine is out of AppleCare (3 years) or the 1 years standard warranty your looking at a very expensive logicboard replacement. At this time you usually consider the cost not worth it and rather spend the money on the newer machine, especially if it's 2-3 years old. This can come as quite a shock as you expected to pay $20 for a OS X upgrade and now have to buy a whole new machine.
You can't not upgrade the operating system for security and bug fixes, however you make sure you have AppleCare that will protect you for three years if such a hardware bricking occurs. If you don't have AppleCare you might want to reconsider taking the chance upgrading the operating system and thus the firmware.
AppleCare can be purchased within one year of the original machine purchase, it gives one 3 years of care from the date of machine purchase, not from the date of AppleCare purchase.
5: Market share of OS x versions (apx)
10.4 4.5% security updates > no
10.5 15% security updates > no
10.6 52% security updates > yes
10.7 30% security updates > yes
10.8 2 million upgraded so far, just released
6: Your decision to upgrade or not
It depends upon your computer technical ability, the age of your machine, your software investment and your budget.
Can you afford to pay for professional assistance if your upgrade doesn't go as expected? Are you in AppleCare?
Can you afford to pay for upgrades to third party software?
Can you afford the downtime while your machine is being repaired?
Can you live without the "new features" newer OS versions provide?
Does your hardware even support the newer features?
You might decide the upgrade is not worth it for your older machine and decide to ease yourself into a new machine gradually. I took this approach with my 2006 MacBook Pro, buying a Early 2011 model. I then upgrade to 10.7 on the older 2006 machine and glad I did, because it got bricked. Turned out 10.7 was a pretty awful upgrade and I was out of AppleCare, however 10.8 seems to be "normal" far as OS X upgrades go, some problems but not mass bricking of machines. -
How do I use Disk Utility to help install Mountain Lion after many failed attempts?
I tried to install Mountain Lion from an App onto my MacBook.
First it said that my disk was damaged to i tried to repair it.
Didn't work.
Then it said I didn't have enough room to install Mountain Lion.
Then I tried to restore Lion.
Didn't work.
Then someone suggested I reset my PRAM.
Tried that, and now I am stuck.
I can't restore any of my backups from timeline.
I can't reinstall OSX because my drive is now locked.
And I don't know how to use Disk Utility to solve this problem!
Any suggestions welcome... I'm in way deeper than I understand and feel like anything I do is making this worse!I gather that your computer is in a less than satisfactory state, so the process below will basically start you from scratch, but you shouldn't lose anything.
Okay, can you inspect the Time Machine Backups with the Finder? About two or so folders down you should start seeing your system files. Assuming all your files are present.
Important^
You probably have an installation disk that came with your macBook. Boot from that CD and install from the CD.
Run the verify disk utilites and repair utilities if necessary.
You may want to erase your disk from the CD's disk utility. This will erase your Hard Drive (make sure you do not erase your backups, as that would be very bad).
Once the installation is complete, run all system updates. Either look through your backup and find the Mountain lion installation app, or download it from the app store again.
Run the ML installtion app.
Once everything is up and running, move all files and folders you want from your TM backups and you should be good to go. -
This message appears every time I try to partition my disk:

I have an MacBook Pro 10.6, using disk utility I tried to verify my disk, but it came up with the message, please use your start up disk, I tried this, starting the computer up and pressing C, but it ejected the disk, the same thing happened while I running the computer. Is the hard drive damaged as laptop doesn't seem to recognize the start up disk ? If so, I presume I will have to put in a new one.
There haven't been any problems with the computer, apart from a sticky curser,I have run a permissions programme from disk utility, there were a lot of different ones, but it seem to be able to fix them.
Any comments or ideas ?
Thank you in anticipation.First backup your users files off the machine to a external storage drive (not TimeMachine!)
Most commonly used backup methods
Next to startup from the disk, have it inserted, hold c or option/alt (wired or built in keyboard) and then boot the computer and or select the disk when it appears and click the arrow.
Disk Utility is under the Utilities menu on the second screen.
Step by Step to fix your Mac
If you used the wrong 10.6 disk, it will spit it out or have issues, use the one that came with that machine or if it's defective, call Apple for a new one. -
Time machine backups are failing. I've followed the instructions I found on the Time Machine troubleshooting page (http://pondini.org/TM/Troubleshooting.html) but have gotten to where I don't know what to do next.
Sequence of events:
The main error message is always:
An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.
Yesterday, I opened Disk Utility and verified the disk. Got this error:
Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.
I ran Disk Utility and repaired the hard drive. Then I manually started the backup before going to bed, figuring it was going to take a long time to run. When I got up this morning, the backup had failed with the same "could be temporary" error. I checked the log, which says:

Does anyone know what the problem is here and what I should do?
Thanks,
TeryYou have repaired your boot drive (which is good) but have you repaired your time machine drive? I don't own a Time Capsule so I don't know if disk utility can operate on it. If it can, you should repair it as well. You may need to erase it and start a new backup. That happens to time machine volumes from time to time and is why people who are serious about their data never rely on a single source of backup.

I have been trying to use time machine on a new lacie 2tb usb 2 drive for back up. I continue to get: "unable to complete backup.An error occured while creating backup folder". When I use disk utility to repair I get another error message: unable to repair disk unmountable.
Help me Obie One Canobie you are my last hopeI have confused myself with the facts! Started out keeping track of every step and every variable but have sort of lost it as we progress here. First I quit all applications then swapped connections between mouse port and backup disk port to influence possible bad connections question. Changed power outlet receptacle for the backup disk. Disabled the put-the-HD-to-sleep option. Then powered down the computerator.
Next started up computerator. Turned Time Machine ON and experienced multiple successful backups! Then I started up a few applications, Mail and Text Edit (but not Safari so far). Had a few more successes. After each backup, I used Disk Utility to verify the backup disk is still OK. This because the error about unable to unmount the backup disk seems to go hand in hand with Disk Utility finding the backup disk to be bad.
Put computer to sleep for the night. Upon starting up in the morning, and before doing anything else, I did a backup disk verification... BAD! Did a restart and verified the backup disk... OK.
Did a few Sleep-bad, Restart -OK repetitions.
It seems consistent: Sleeping the computer apparently messes up the backup disk but doing a Restart "repairs" it.
=============================
Now then, I don't understand everything I know here. Methinks that maybe keeping the HD from sleeping during lulls in activity has allowed successful backups through the day but manually putting everything to sleep for the night causes a return to the problem of spinning-back-up-too-slowly (which was explained earlier). Is there any truth in this?
I may abandon this Seagate thing for something more compatible. What's out there that we know works reliably for us? -
Getting medium write error on burning a disc image using Disk utility
Have a MacBrook Pro 15 inch, circa Summer 2007, using OX 10.4.11. up until recently (as in before February) have been able to burn DVD's using Toast (message Medium Writer Error). Started getting problems where the burn failed. Thought maybe it was Toast, so I tried creating an iDVD project and tried to burn the DVD using that, and it stopped in the middle as well and then spit the disk out with no error message.
, this time I tried creating a disc image, and used disk utility to burn. The process looked like it was going to work but then failed with a message that I have a medium write error.
I have no problems burning a regular data disk on my superdrive so I am thinking it's maybe a software glitch rather than hardware. . Any thoughts, as to what could be causing this problem all of a sudden. By the way, there are other users out there, who seems to be having DVD burning problems all of a sudden, but most people suggest other media. I am using the same stack of DVD-R's from before when I had no problem.Well, I had assumed my media was ok, since I had a spindle of DVD-R's and had used many of them successfully (until now!, ha ha).
I went out this afternoon and bought another brand (Memorex) and it successfully recorded.
So hopefully this solves my problem, I had no idea it was the media since I had used several of them before.
Thanks for your help. -

Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation and after having selected both my destination and source drives, the operation begins but soon fails due to input/output error. If I try to create an image of the drive it gives me the same error message. Any help would be much appreciated.
Disk Utility only creates a image of the drive, so it's no help getting exactly what you want, which is your files. If the file structure is messed up or the drive is failing then it's no help.
If you have a external boot drive and you can't access the internal non-booting drive though the typical Finder and windows to transfer your files via drag and drop methods, then you need to install Data Rescue on the external boot drive and it will do as best as it can to recover your files. (works on non-encrypted/non-Filevaulted drives only)
.Create a data recovery/undelete external boot drive
Are you sure you have hard drive failure, or that OS X isn't merely not booting?
Because if the drive is working physically, then there is a host of fixes
