Apple Service Diagnostic Dmg External Hdd

Aug 20, 2019  After isolating an issue on your Mac to a possible hardware issue, you can use Apple Diagnostics to help determine which hardware component might be causing the issue. Apple Diagnostics also suggests solutions and helps you contact Apple Support for assistance. If your Mac was introduced before June 2013, it uses Apple Hardware Test instead. Transforming the failing Macintosh start-up drive to an external hard drive for recovering inaccessible files could possibly be an alternative solution of the Target Disk Mode. Note: The conversion of Macintosh HD to an external hard drive is also useful for recovering its.

Data conversion from.IMG to.DMG is the conversion of computer data from Cd/Dvd Image File to Apple Mac Os X Disk Image. Throughout a computer environment, data is encoded in a variety of ways. Dmg to iso converter. Disk images in CloneCD format (.img files) can be converted to basic macOS / Mac OS X images (.dmg files) with programs like AnyToISO or similar dedicated disk image conversion programs, some of the good picks capable of img to dmg conversion are listed below. Updated: March 14, 2019. Apr 02, 2019  To convert DMG to ISO, first open the PowerISO application on Windows and then select the tools option from the top ribbon. From the dropdown list, select the option labeled as convert. Now you will see a dialog box titled convert image file. You can use this to convert image files from one file format to another.

On the one hand Apple now recommends you simply use the disks that came with your Mac on the other hand Apple says 'discs are dead' and removes optical drives from Macs. How crazy is this?
But great hint :-)

Had our esteemed moderator tested this hint, he would have found it doesn't work as described. System/Library/Core Services is only writable by the user when preceded by 'sudo'. Thus, the correct syntax should be

Yeah, you're quite correct! Sorry for the mistake.
Somehow I forgot to add that in when writing the hint (or I was using the root account at the time….)
Anyway, yes, sudo must be used. (It would be nice if the original hint could be modified. :))

Fixed it. Thanks for the catch.

1) Try restarting your mac, and trying to open the.DMG again. 2) Hold down the Control key when you click on the.dmg then select Open from the context menu. Theis should give you a window to 'allow anyway'. If neither of these options solves the probelm for.

Sep 21, 2007  How to Install Software from DMG Files on a Mac 21 September, 2007 by Tom Harrison in mac os x A.DMG file is a container file commonly used to distribute applications for Mac OS X. Installing software from one of these requires you to mount the image and move its contents to your computer’s “Applications” directory.

Had out esteemed smarta$$ looked, he'd have seen that Baltutis below posted the correct command.
If you're gonna call someone out, be smarter.
sudo cp -R /Volumes/[your INSTALL DISK name]/System/Library/CoreServices/.diagnostics /System/Library/CoreServices

If you use the discs that came with your Mac, you can also simply install the 'CPUHelpFiles.mpkg' metapackage, usually on the Applications Install Disc (part of 'Install Bundled Software': select only 'CPU Help Files' and deselect everything else): this will install AHT and also the documentation files for your machine.

I forgot about the CPUHelpFiles package because other utilities in there (such as the processor pref pane seem to be broken now), but that does work if you would prefer not to use terminal.

Well, rather, the 'Processor' preference pane was an optional part of the Developer Tools (up to version 3.x for Snow Leopard), while 'CPUHelpFiles.mpkg' installs only AHT and the machine-specific documentation stuff inside '/Library/Documentation/User Guides And Information': so, it should be quite safe too install, as there are no extra utilities there.

Of course, *to* install (not 'too')..

I'm pretty sure this doesn't work if your boot volume is encrypted. You'd need to create a separate unencrypted boot disk/partition, boot to that, install AHT, then boot into AHT.

You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. You can create a disk image that contains the contents of a folder or connected device, such as a USB device. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. Create dmg from dvd. This method doesn’t copy a device’s free space to the disk image. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 10 GB in size and include only data, not free space.

On encrypted systems, there is a small booter partition which contains the EFI application that asks for your password, loads the kernel from the booter partition and once the kernel found and unlocked your encrypted volume, system startup continues as usual.
If your system has the recovery system (and most Lion installs should have), it and the booter share a partition after your root volume. diskutil list will confirm there is this hidden partition called 'Recovery HD'. If your system for some reason does not have the recovery system, but you encrypted the root volume, the partition will be named 'Boot OS X'.
Either way, just mount this hidden partition ('diskutil mount Recovery HD' or 'diskutil mount Boot OS X') and then copy the .diagnostics folder to /Volumes/{Recovery HD|Boot OS X}/System/Library/CoreServices.
After that, you can boot to AHT by holding D, like on unencrypted systems.
It is probably a good idea to copy AHT to the Recovery HD, regardless of the encryption status of your root volume, but I haven't tested if the firmware finds AHT there when the partition is not the first HFS+ volume on your primary disk.
Curiously, one can boot the recovery system, but not AHT, when the firmware password is set..

I just tried doing this, but there isn't enough space on the recovery volume to copy all of the files in the .diagnostics folder. : (

Maybe I'm wrong, but the command should be:
sudo cp -R /Volumes/[your INSTALL disc's name]/System/Library/CoreServices/.diagnostics /System/Library/CoreServices/

You are correct, BT! Slight difference, but then that's what makes things work or not!

For Older Windows Operating SystemsIn older Windows OS’s the conventional approach should be the effective one:1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.2: After the search window appears, choose More Advanced Options from the search assistant box. We recommend to wait for the green loading bar in the navination box to fill up in case the PC is looking for the file and hasn’t found it yet. https://tianineslu.tistory.com/15.

FYI, I couldn't get 'D' to work on a 2011 MacBook Air. My drive is encrypted and I had a firmware password turned on. Once I disabled the firmware password, 'D' worked. That's a bit unfortunate, as what if my drive has died? How can I reach the recovery partition to disable the firmware password to get to the hardware test.

great hint but AHT is pretty worthless and no longer really used. If you want to run diags on your computer that will actually do something, use apple service diagnostics (ASD) for your model instead

I could not find my original disks, but was able to restore the .diagnostics folder from a pre Lion upgrade time machine backup. Had to show hidden files first, but then just went back far enough and restored that one folder. Boot while holding D worked fine.

HELP! Can't do ANY diagnosing on Late-2011 MBP w/ 16GB RAM! :-(((

Alright, I still don't understand how to find either the 'Holding the D' function and/or some other utility (3rd party or Apple) for those of us who have a (Late-2011) MacBook Pro!? No disks, just a useless SuperDrive and no USB stick either. I did make myself my own USB restore flash drive, however, and I also have the Recovery HD partition unhidden, mounted, but I just cannot seem to locate this '.diagnostics'..folder(is it?) or is it a pkg or a file? :-( System files are also visible, so I did some manual searching for the elusive diagnostic 'something-or-other'. No dice across the board. :(
I would really like to check my 2x8GB RAM chips, which, thus far, work perfectly fine and show up correctly everywhere they should, including System Info/Profiler, 'About this Mac', iStat Menus, Activity Monitor, and a few others. I just want to make sure, as I had not heard of that memory company before and the price was incredible ($139 shipped, no tax for BOTH from a seller on Amazon).
Thanks for helping! ;-)

I've got MacBook Pro (15-inch, Late 2011) with Apple Hardware Test originally accessed by holding D at startup.
However after restoring Mac OS X Lion by the Internet using Lion Recovery D-key stopped working. I've followed the tip and copied .diagnostics folder:
ls -al /Volumes/Macintosh HD/System/Library/CoreServices/.diagnostics/
total 48
drwxr-xr-x 3 root wheel 102 Feb 13 16:06 .
drwxr-xr-x 125 root wheel 4250 Feb 13 16:06 .
-rwxr-xr-x 1 root wheel 22590 Feb 13 16:06 diags.efi
and
ls -al /Volumes/Recovery HD/System/Library/CoreServices/.diagnostics/
total 48
drwxr-xr-x 3 User staff 102 Jun 27 2011 .
drwxr-xr-x 4 User staff 136 Jun 27 2011 .
-rwxr-xr-x 1 User staff 22590 Jun 27 2011 diags.efi
However the D-key still doesn't call AHT as expected.
What else should I try?

Apple Service Diagnostic Dmg External Hdd Windows 7

On newer Macs (which shipped with Mavericks), Apple Diagnostics initially is on the Recovery HD; so, after mounting it with:
$ diskutil mount Recovery HD
.. Apple Diagnostics is in the folder:
/Volumes/Recovery HD/com.apple.recovery.boot/.diagnostics
So, the best thing to do would be to make a copy of this invisible folder (personally, I zipped it and stored it on an external hard drive), in order to be able to restore it if you reinstall OS X (which also updates the recovery partition, removing the '.diagnostics' folder); when restoring it, also remember to restore the original permissions for the '.diagnostics' folder and its contents: i.e., essentially, root read-write, wheel read-only and everyone read-only.
Sadly, presently there seems to be no way to re-download Apple Diagnostics from Apple and reinstall it: so, if you didn't make the backup copy from your initial, out-of-the-box setup, the only option remaining is the Internet-based one, as also explained here:
http://support.apple.com/kb/HT5781
(Probably, the situation is similar also for Macs which shipped with Lion and Mountain Lion (with AHT)..)
