.dmg 10.9.3 to 10.7.5

When copying a .dmg file from 10.9.3 mac to a 10.7.5 mac I always get the warning "There may be a problem with this disk image. Are you sure you want to open it?". I open it and it works fine and don't get the warning again. It just happens the first time it is opened on the 10.7.5 mac. I have no problems with it on the 10.9.3 mac. I need to move it from 10.9 to 10.7 and wonder what the issue is and how to fix it.
Is there a backwards compatibility issue?

It may be a code signature (used for security). In general, Lion supports tagged downloads, but it doesn't support Gatekeeper, so it's possible the 10.7.5 machine is getting confused. When you say it's OK, Lion will write its own code signature indicating it's safe, I believe.

Installation problem on new macbook pro i7 How do I get a DMG or firefox icon on desktop?

I can't see anything but the name label on the DMG file. The blue dialogue box only has the applications folder in it. I tried installing both 3.6 and 4 beta versions with the same result.

Make sure that Firefox gets installed properly. 
Open the DMG file and drag to Firefox program to the application folder on your hard drive. 
You shouldn't double-click the Firefox application to run it from the disk image, but drag it out of the DMG folder instead.

Copy file from mounted DMG to the Applications folder?

I'm wanting to copy file (application) from a mounted DMG to the Applications folder. Something like:
tell application "Finder"
try
copy "Volumes:Dropbox Installer:Dropbox.app" to folder "Volumes:Macintosh HD:Applications"
end try
end tell
(But that doesn't work).
Preferably overwriting the existing application in that folder. Any help would be greatly appreciated.

tell application "Finder"
duplicate file "Volumes:S001TEST:S001-S001c-TEST.zip" to folder "Volumes:Macintosh HD:Applications" with replacing
end tell
I tried this principle in Applescript (Mavericks) and received error...
Finder got an error: Can’t set folder "Volumes:Macintosh HD:Applications" to file "Volumes:S001TEST:S001-S001c-TEST.zip".
"001TEST" is a disk image with filename of "S001TEST.dmg"
Any ideas why this won't work?

In trying to update I received this message: Firefox 3.6.3(2).dmg.part could not be saved, because the source file could not be read.

In trying to download an update I first received: "There were problems checking for, downloading, or installing this update. Firefox could not be updated because: No data was received (please try again)" It also gave a link to download manually. When I tried from the Firefox website I got: /Users/(deleted for privacy)/Desktop/Firefox 3.6.3(2).dmg.part could not be saved, because the source file could not be read.
Try again later, or contact the server administrator. I tried this 3 times.
== This happened ==
Not sure how often
== Mon around 11 am, central time, May 17, 2010

I have tried downloading the file several times and get the same message: "No data received." I have no other system problems, I navigate well to other sites, but I'm unable to download this upgrade. Any suggestions?

30GB of space disappears on External Drive after failed DMG copy via USB

I have a 298.1 GB external Western Digital hard drive connected to my iMac by a USB 2.0 cable. It is formatted in NTFS-3G so I can use it with both my PC and Mac. Yesterday in Disk Utility I created a 50GB 256-bit encrypted DMG and told Disk Utility to save it on a folder in my external drive. It got to about 20GB and then my house's power went out. A few hours later when the power came back on, I turned on my computer, and the available space on my external hard drive went down from about 100GB to 68.21GB.
The first thing I thought was that the DMG transfer ended prematurely so I should just find and delete the incomplete DMG from the hard drive. So I went to the folder I saved it in and it was not there. I checked all the folders and I couldn't find any DMG in there. Then I went to the root of the external drive and used Get Info to find the space each folder took up. It adds up to 194.12 GB. So I subtracted 194.12 from 298.1 and got 103.98. If I'm supposed to have 103.98 GB, why do I only have 68.21 GB available? I double and triple checked the size of everything on the disk and I still should have about 30GB more than I do. The 30GB just disappeared.
I tried verifying the disk in Disk Utility and got:
2009-06-14 11:12:33 -0400: Verifying volume “SHADUSMEDIA”

Can anyone help?

Greetings world.I have created a dmg. of my entire iomega ext HDD via disk utility using a mac book pro. It is currently sitting on the desktop. I have erased the iomega and now I can not understand how to put the dmg back.

It is safe to say that i need help..................
let me start at the beginning.
I have 1 2008 imac. always a pleasure never been a problem. Attached to it i have an iomega 500gb ext drive. also been ok.
until now!!
The HDD would not mount. Disk utility suggested that it was ok so i tested the imac HD. I got error code 4MOT/2/40000004: HDD- 1502. This doesnt worry me at the moment.
I attached iomega to my Mac book pro and again it would not mount. The disk utility did tell me that the iomega needed repair. it advised that i should wipe it and restore.
So I used the MB Pro disk utility to create a DMG. and saved it to the desk top. I then erased the iomega. did a repair and it all seemed ok. So then i try to do a restore.
After a very long time it said internal error with the dmg. using disk utility i did a convert dmg (compressed) and saved it to the iomega. middle of the night job!!
got up this morning and indeed it had sent the DMG to the iomega. But i could not open it. The iomega itself seemed dandy asking me if i wanted to use it as a time machine etc and it mounted ok and i saved a small jpeg to the iomega as well. I then thought that maybe when i did the convert as a compressed file i made a mistake. i'm guessing it should be a read and write so i started all over again.......... wiped iomega (which was quite quick) then tried the convert tool again.....it trys for a while then says there is not enough disk space...........I'm not sure which disk it is refering to.??
I have purchased a 1tb hard drive today incase the iomega is some how full up.
So really my question to the world is .........Help?

well no reply from the community. sniff- do i stink!? - probably a little bit. If i have lost all that data then I'm gonna really really pong.
Any ways i have purchased a 1tb usb HDD and have managed to duplicate the dmg file onto it. however still unable to mount the **** thing. so now i have ordered disk warrior which will be in my possession tomorrow.
fingers toes eyes crossed.

Need help booting from DMG file without DVD drive

okay so i have 6 computers with me right now. i need to use one that has a dvd drive to install it on a comp that doesnt via firewire.
1- macbook with superdrive and os 10.5 (cant even open tiger install because its a new macbook
2-iBook g4 with DVD drive BUT the firewire port is broken
3-iBook g3 (one that needs tiger but only has a cd drive)
4-ibook g3 (without dvd drive)
5-powerbook g4 with dvd drive and firewire (for some reason will not read the tiger discs i just burned, even though ive already used them on the ibook g4
6-mac pro with firewire and dvd drive, but the dvd drive is broken.
so seems to me, every computer i have has a weakness for exactly what i need. what i need to know now is if i can boot the powerbook g4 from a DMG file of tiger install disc 1 and install is to the target ibook through firewire. if you have any suggestions on what i should try with the supplies mentioned above, please inform me. thanks!

what i need to know now is if i can boot the powerbook g4 from a DMG file of tiger install disc 1 and install is to the target ibook through firewire.
You can't unless the PowerBook is running Mac OS X Server, in which case the NetInstall feature can be used.

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 Marco

HI 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.

What is an 'SPL-2.dmg' file and how can I get it (the driver) installed?

subject line is question

*My question to Samsung:*
"SCX-4200 driver for Mac OSX.5.5
After downloading the driver from
http://www.samsung.com/us/support/download/supportDownDetail.do?group=&type=&sub type=&modelnm=SCX-4200&language=&cate_type=all&mType=DR&dType=D&vType=L&cttID=2047002&prd_i a_cd=06010300&dispnm=SCX-4200,
the following error message is displayed: 'The following disc images failed to mount - image: SPL2.dmg; reason: not recognised.'
Please advise."
*The reply from Samsung:*
Thank you for contacting us regarding your SCX-4200 and the recent issue you have experienced.
It is difficult to say why this error may have occurred, it may be that the file has been corrupted during transfer. You should try deleting this file again and re-downloading it or possibly even try downloading the file from an alternate location such as below -
http://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=uk&C ttFileID=2047002&CDCttType=DR&ModelType=N&ModelName=SCX-4200&VPath=DR/200810/200 81028145509765/SPL2.dmg
Should you wish to discuss this issue further, please feel free to call our IT Helpdesk on 0845 726 7864 quoting your reference number."
*Having tried all that, I did phone them, only to be fobbed off, +'Try re-installing from the CD you got with your printer. If that doesn't work it must be their ([Apple's]) problem.'+*
My MacBook is trying to mount it, according to right-click 'Get Info', using DiscImageMounter, which only returns the error message (above), 'The following disc images failed to mount - image: SPL2.dmg; reason: not recognised.' Disc Utility doesn't tell me much more. What should I do with it?
My printer (Samsung SCX-4200) clicks and warms up when it's sent a command to print, but that's the end of it - it won't do anything else, which is why I went looking for the driver in the first place. Note the Samsung Download Centre site at _http://www.samsung.com/uk/support/download/supportDownDetail.do?group=printsolut ions&type=printsolutions&subtype=monomultifunctionproducts&modelnm=SCX-4200&disp_nm=SCX-4200&language=&cate_type=all&mType=DR&dType=D&vType=L&ct tID=2047002&prd_ia_cd=06010300 says this driver was updated/uploaded 28/10/2008, but I can't get the **** thing to install. Any idea what I'm doing wrong?
Probably also worth noting: the printer works fine with Windows on my MacBook's BootCamp partition.

The dmg files have downloaded to the wrong folder - not finished with the install process

The dmg files have downloaded to the wrong folder - I am at the part of the download/install process where the "Welcome" screen appears asking for me to agree to the license agreement. Somewhere on your site, I read that they should NOT go to the applications folder but to the "Users" folder. Can/should I move/drag the folder with the dmg files into the "Users" folder"? If so, before or after I complete the install? I am running MAC OSX 10.7.4 on a MAC Mini.
Also, when the trial period is over, I will use the license number for the purchased software disks, should the dmg's/folders then be moved to the application folder or stay in the "users" section? I have Purvhased Adobe Photoshop Elements 10 and Adobe Premiere Elements 10, but somewhere on your site it was suggested to download them instead and use the license code at the appropiate time. If someone can help with these questions, I would appreciate it. Thank you

Hi,
In the Welcome screen, you can accept the license agreement and can go ahead with the installation. You will be asked for the serial number. If you don't have one, install it as a trial application. By default, it's installed in the Applications folder. However, you can change the installation folder in the third screen, if you have a reason. Please see the screenshot below:
After installing, you can't move application to a different directory by dragging. You need to uninstall and install it again in the folder of your choice.
Thanks,
Sunil

HELP! Creating symbolic link to home folder for installer DMG

Guys,
I'm in a bit of a bind. I need to create a symbolic link for an installer DMG to distribute a communal Bookmarks.plist to all the computers in my department. Unfortunately 'ln -s ~/Library/Safari /Volumes/Bookmarks/.' doesn't do the trick! While it creates an alias that functions on my machine, when that DMG is compiled and distributed from the original sparse image, the alias fails to link to that location on whoever attempts to mount the DMG. Any ideas?? Thanks!

Symbolic links break when you change the machine on which they were created. Use an standard Mac alias instead as I believe they will work as expected.

Can't copy files from mounted DMG. What's up??

So all of a sudden, I can't copy files from mounted DMG files. It's strange because if there is one file and I drag it to another location, like desktop, it won't copy. If I drag 2 files from the mounted DMG to the desktop one of them copies. If I drag 3, then 2 copy... it's always all but one of the files... never all of them.
I've tried repairing permissions but nothing works. I'm at a loss...
thanks

Try holding option when you drag the files. This tells the mac to move the files to the desktop of your computer not the desktop folder of the DMG (usually a hidden folder)
If that doesn't work it may be that you need administrative privileges to move the files. Make sure you are logged on as as an administrator by selecting the account tab in system preferences and making sure it says "admin" under your user name. Log on to or create an administration account then try moving the file.
Hope this helps, let me know

Copying a file from a .DMG to Desktop causes MBP to reboot?!?!

Here's a good one. I was installing my apps on my new MBP 2.16 and I'm being very careful, only installing apps that are universal or works well with Rosetta.
I installed Toast 7.0.1, downloaded 7.0.2 (Roxio says they have some of the interal components in universal form) so while moving the new Toast.app from the DMG, the MBP would reboot when 80 of 114 MB are transfered. Just a quick reboot, no messages or anything. I was able to do this 3 times straight. The copy from the DMG to the Applications folder caused the reboot, but when I copied it to the Desktop, it worked.
Here's one possibly contributing issue, my MBP battery was DOA. It won't hold a charge but the MBP works well when connected to AC. I verified that the MagSafe connector was clean and had a good connection (MBP owners would attest that it's nearly impossible to not get a good connection).
The only other issue that I could think of is heat. Could heat cause a reboot? I had it on for about an hour installing apps, but it was sitting on a roadtools riser.
thanks...Lee

Lee,
Quite wierd that it seems to be happening when copying that file and you were able reproduce it three times. Has this happened at other times?
Since you stated your battery was DOA, I wonder if this somehow corrupted the PRAM and/or Power Manager Unit? Try resetting both to see if this takes care of the issue. Below is the link with instructions on how to do this:

I am having trouble with replacing my old Firefox version 3.6.3 with the new 9.0 version on my Macbook. I have it downloaded as a dmg file, but I keep getting a message that the opertion cannot be completed because the item Firefox is in use...HELP!

After having the issue with my photos being blocked on Facebook, I was told I needed to upgrade to the newest version of Firefox and that the version I am currently using (3.6.3) is no longer supported with security updates. I have tried to follow the steps in the upgrade process through Firefox itself, but have been unable to do it...I would love step by step instructions to walk me through it as I don't know what I am doing wrong.'''bold text'''

If there are problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the disk image (dmg) file to the desktop
*Firefox 9.0.x: http://www.mozilla.org/en-US/firefox/all.html
*Trash the current Firefox application to do a clean (re-)install
*Install the new version that you have downloaded
Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data if you uninstall and (re)install Firefox.

Files disappearing from mounted .DMG files

Hi, I've had this issue occur a few times in Tiger and I'd like to know if anyone else has experienced this and if there's a known workaround. Sometimes, when browsing a disk image, or, less commonly, a physical disc like a CD, files in the Finder will seem to disappear from the image/disk when clicked on. First the filenames will go, then the files themselves, and evidently those files then become unreadable in general as applications can't access them. I don't get any error messages; it's just like the filesystem on that disk eats itself away and vanishes. I can unmount the disk without any issue.
I'm having this problem right now with any disk image I mount on my XServe -- it goes through the "Verify" step just fine, shows up on my desktop, I can browse and even open files, but inevitably within a very short period of time the above occurs, and it becomes useless. I KNOW it can't be the .dmg file that's the problem, because if I share the .dmg over Personal File Sharing and mount it from another Mac, this problem does NOT occur. It's just on the one Mac hosting the files. Any idea what this could mean, and what could solve it?
Also, I know a lot of times a restart will cure this weird little glitches, but I would really like a solution, if you know what I mean... particularly on a server, I cannot afford to restart whenever I have a problem.

Sounds like you have run into a very strange, and unfortunately no uncommon, bug involving file systems from either servers or FAT 32 mounted external drives. See this discussion:
http://discussions.apple.com/thread.jspa?messageID=5310151
Read on down away to see some replies from people who did some pretty thorough investigations of the problem.
