Boot with Ignore Ownership

I realize you can/should only boot from a disc/volume with Ignore Ownership not selected but....
I clone our second Mac from my Mac to a volume on an external FW drive connected to my Mac. It is set so as to not Ignore Ownership.
However if I then connect that FW drive to the second Mac that same volume shows as set to Ignore Ownership.
I'm concerned that in an emergency that my backup clone will not work because of this change in ownership setting.
Appreciate any advice. Thank you.
Powerbook G4 Ti Mac OS X (10.4.5)

Not if you weren't able to boot before. The behavior of your clone once is indicative of what it will be in the future until the clone is remade. I suggest double-verifying on your next clone that the Ignore Ownership checkbox is unchecked before you make the clone. If it still isn't able to boot after the clone is made, either your cloning software is not able to make a bootable volume, or the Firewire case you have is not able to boot your machine due to the Firewire case's firmware.
The ones by Granite Digital, LaCie, and Otherworld Computing I know are, or at least you can request to have cases that are from them.
The software for cloning that works best of late for me has been Shirt Pocket software's Superduper, and the latest Retrospect Express 6.1. LaCie's Silverkeeper sometimes works. Carbon Copy Cloner is also able to clone, however, it has one significant weakness, and that's if the clone is partial, it leaves behind a huge temporary file in the /Volumes/ folder.

With OSX 10.8.5 The backup can't be copied because the backup volume doesn't have ownership enabled. how do i enable if i dont see the ignore ownership option?

With OSX 10.8.5, there is NO check box to ignore ownership on this volume. What can I do? I can't copy the Backups.backupdb files to a new bigger backup disk.

Anyone know Disk Utility, Ignore Ownership, and disk image DL DVD issues?

I am currently having issues with backup DVD's I burned using Disk Utility. I can put the dual layer DVD's in and the system reads them. When I try to pull a file off the Dual Layer DVD a circle with an X appears notifying me that I cannot copy the files to my desk top.
When I check the DVD's permissions it reads Admin (me) read and write with the ignore ownership checkbox checked...which means I should be able to pull files off the DVD. The only way I can currently get information off the DVD is to duplicate the entire disk to a new folder by selecting the DVD while holding down the Cntrl key and selecting duplicate. I have had other issues with DVD's and disk images in Leopard....including having to eject either through disk utility or by selecting the image with the Cntrl key held down. Finder eject, keyboard eject, and the menu eject selections suddenly report that the disk is in use.
The DVD's were burned by creating a dual layer dvd image through disk utility with the read/write option checked.
After duplicating 2-3 disks, the system itself is unable to mount any more disks from the series of backups. When I look at disk utility it reads that the disk is not mountable. I have to restart my computer so the system can continue to read the backups.
My Itunes disk backups are marked the same way (ignore ownership) with admin read/write privlages....I have no problem pulling files off these disks.
I have tried both logging in as root and booting from an external drive...same problem. Is this some nasty Disk Utility bug? Is anyone else having bizarre permission related issues with Disk Utility and Disk Images.

When you create the image in Disk Utility, did you
change the 'Partitions' setting?
If you leave it to read 'CD/DVD', it will create a ISO9660/UDF image.
To be able to maintain permission and extended file attributes, you
need to select 'GUID Partition Map'.
I assume you used iTunes to create your music backup?
It seems it creates the correct image type for you.
Before sending this message, I actually created a single layer image,
copied some files to it and gave additional permissions to other users on my system.
Afterwards I copied the files to my Desktop, verifying that the attributes are still intact.
Best regards
(It took quite a while to burn this 4x DVD-RW Anyways, I hope I could help)

Set "Ignore ownership on this volume" to be on by default

Hello, I have a MacPro loaded with 10.5 server that I use frequently for backing up customer data via USB or Firewire. The MacPro is in a locked room and is relatively isolated from the network. I am looking for a way to set "Ignore ownership on this volume" to be checked by default for any/all drives I plug into the machine. This would be a huge time save for me. Thank you!

Hi Alfredo,
I can't test this at the moment, but I have a theory!
One would think that setting iTunes to a FW Dive would need to change the Permissions to control Sharing of iTunes content.
My iTunes was set to another internal drive and had the same Ignore unchecked and owned by system, I unchecked it and changed it back to my boot drive, the Get Info change Me to owner & kept the Ignore checked... setting it back to the other Drive did not change those settings, but I suspect that a Reboot would... how else could Apple control Sharing of songs?

Ignore ownership box on disk info panel is missing.

I've lost one of my external disks and am using diskwarrior to attempt to rebuild the directory so I can move files off the drive. I'm on a macbook pro with tiger 10.4.8. Diskwarrior is version 4. After installing it when I try to run it errors out with an error about ownership not being sufficient in tiger and requests that I uncheck the ignore ownership box on the drive or the dmg (not sure which). In any case there is no ignore ownership box to uncheck on either device.
The device is a newly formatted boot device on which I freshly installed tiger. Neither the device nor the original disk in the macbook pro have this checkbox available. How can I restore the check box or how can I accomplish the same thing with another utility including chown or chmod?
thanks,
Mike

Thanks, I actually got by the ignore ownership problem. Someone elsewhere said that box shouldn't show up on the root/boot drive so I rebooted under the old boot and then looked at the newly inited boot device and there was the box. That got me past that problem. However now I can run disk warrior from a nonboot drive with the os installed but after agreeing to the license it fails with a message:
"An unserialized copy of Diskwarrior cannot be run from locked media, either restart
from the DiskWarrior disk cd or install disk warrior onto a hard disk."
There are lock checkboxes on the DiskWarrior DMG, the utilities folder and the applications folder in their respective disk info panels but they are all unchecked. There is no checkbox on the drive itself.I have no idea what this means and there are only two incidents of it on google neither of which are helpful. At this point I think I'm going to have to wait for alsoft Tech support.
thanks,
Mike

How to "Ignore Ownership On This Volume" When Saving File to External Hard Drive?

Hello,
I just switched over from Photoshop CS3 pc platform to the MAC version, and it gives me the message that I can't save what I've I've just done - I have my photo files on an external Seagate Free Agent Hard Disk - When I followed the instructions to "Select Disk/Choose File/Get Info/Click Disclosure Triangle next to Sharing & Permissions" - Then after I did all of this, there was no option to select "Ignore ownership on this volume." Instead, the only thing it said was, This is read only."
Surely, I don't have to give permission to save each and every file - This is a very serious hobby for me, but I am doing it out of my home, and no one else at this time uses my computer.
Before submitting this request, I called Apple support first, and they tried doing a Disk scan and repair of the permissions, but this was only for the internal Macintosh HD drive, not the external one that is related to this incident.
Thanks For Your Help ahead of time!
Also, this might should be saved for another separate question, but I had to set change my resolution to 1920 X 1200 - The text, etc, was much too large for especially doing anything in Photoshop. This new iMac has a 3.06/4 GB RAM/1 TB internal HD/NVIDIA GeForce 8800 Graphics Card.

Buko-
To tell you the truth - and I apologize for that statement - I woke up early this morning, and it hit me that I took what Lundberg02 said earlier the wrong way! So, I couldn't wait to get back on and apologize to him and all of you - And I hope that you will forgive me.
When I think about it now, perhaps he is right - This may not have been a pertinent place for me to insert this question. But after spending a long time with Apple about it, and then Seagate - I decided that the only other place I could go was to ask you guys. I thought, perhaps someone here had encountered the same problem when switching from pc to Mac platform. But perhaps I shouldn't have.
Actually, Seagate - I think - solved the problem, at least this erase procedure was working after two hours - until I decided that I'd cancel it, and take it back to Costco for a refund, which I did. And the Seagate rep told me that he didn't blame me, because the drive was getting a little old, and if I used their warranty program, I'd probably gotten a refurbished one, anyway. So, all of this trouble I've put you good people through has gone "for naught".
But hopefully, you'll be acceptable in the future when I ask more applicable questions, when my wheels really start spinning. Otherwise, I probably won't come here that often, anyway. I just enjoy fixing up old black family photos and coloring some of them. And I got the basics down. You know, like cloning, healing, and layering them to death!!
Thanks for understanding - And for forgiving me.

Dual boot with Ubuntu 13.0 using bootable USB problem (Y410P)

Hi I recently bought Lenovo Y410P and have been since trying for hours to dual boot with Ubuntu but I was unsuccessful.
I formatted by USB drive in FAT format, and created a bootable usb using Pendrive. Then I changed the Boot Mode to Legacy Support and the boot order so it boots from the flash storage first.
Then it hung on a purple screen like this: http://img829.imageshack.us/img829/3509/dgfdgrunningoraclevmvir.png
and the keyboard doesn't work and I couldn't go any further from here.
So I tried to use a different program called Unetbootin, and the problem got worse and it just stopped working at the option screen where you select whether to just try Ubuntu or install it, etc.
I read it somewhere the recent version of Unetbootin doesn't work, so I got the 474 version of it, and finally I was able to select from the option menu and it didn't hang. However when I clicked on Install Ubuntu, it just stopped there for a while, and then the boot failed and moved onto Windows 8 again.
I looked at the USB drive, and I realized the folder and some config files are names isolinux instead of syslinux, so I changed them, and now I'm getting the "SYSLINUX 3.86 2010..." words on the black screen and it hangs there.
I saw a similar message before using Pendrive and it was like "SYSLINUX 4.10 2012...". That was because the flash drive wasn't formatted in FAT (it was FAT32). So I re-checked the drive, but it is indeed formatted in FAT so I'm not sure why now I'm getting a similar message.
It will be much appreciated if you could give me some suggestions as to how to solve this problem.
Thanks

Something else you could try. Not sure it will make any difference.
Skip the boot creation tools and just boot the thing in UEFI mode.
Use the latest (12.10 or later will work, IIRC) 64-bit Ubuntu ISO. Format your flash drive as a single FAT32 partition. Extract the contents of the ISO to the flash drive. Use 7zip for Windows, or your favorite Linux de-archiving tool. That's it.
[edit] I don't believe the partition needs to be set active, but haven't tested that.
Set BIOS boot mode to UEFI. Even secure boot mode should work withe a new enough Ubuntu - but isn't necessary.
Give that a try. If it still barfs at the same place, mess around with the start-up graphics options.

System won't boot with incorrect date/time

Hey, I setup a computer back home for VNC, however there was a power outage and now the BIOS has reset. Unfortunately it defaults the date to 2099 for some reason, anyway now the computer won't boot (I can't remember the exact error). Anyway the trouble is I can't access that computer now, and it has no monitor hooked up, is there anyway I can force a boot with just keyboard and without setting the correct date in the BIOS (no one with access to the computer could do this).
Appreciate any help.

You can try to just press F1.
I have a similar issue with my home server, the battery on the motherboard is dead so when the pc is powered off for a while it will not remember the clock. When trying to boot the system in such a case it spits out an error where it offers to "ignore" the error if you press F1.
In my case I need to wait until my pc beeps before pressing F1, basically you need to get past the BIOS stage.
With a bit of luck it might work for you too.
Also I hope you have some ntp service running on your system to make sure the date gets set correctly on your system on bootup.

Old Macmini ignores ownership on external HD's, new Macmini does not.

Hi - my old Mac mini has a couple of external HD's set to "ignore ownership on this volume", as they are just storing personal files, one backing up the other nightly. I transferred them to a new Macmini, only to find my backup software won't update from one external to the other (permissions type error messages), and the "ignore ownership on this volume" checkboxes on each are not checked, and greyed out.
I've tranferred the HD's back to the old Macmini, and presto the "ignore ownership on this volume" boxes are now checked again. How can I make this behaviour transfer safely to the new comp?

Thank you! I haven't yet dared try this, but I've found the following info that explains those commands in a fashion even I could understand - I take it this will work for all enclosed folders too? -
chmod stands for "Change Mode".
The numbers part is a little more complicated.... "777" is three numbers..to be nerdy and specific.. it is three 3 digit binary (base 2) numbers converted into three 1 digit octal (base 8) numbers.
The first number stands for "user", the second group stands for "group" and the final number stands for "other". There are three possible things that can be done with a file: read, write, and execute.. Here is a little reference:
execute = 001 in binary = 1 in octal
write = 010 in binary = 2 in octal
read = 100 in binary = 4 in octal
So where does the 7 come from?
7 in binary = 111 in decimal = read, write, execute
So you get:
read write execute = 111 = 1 + 2 + 4 = 7
read write no execute = 110 = 4 + 2 = 6
read no write execute = 101 = 4 + 1 = 5
read no write no execute = 100 = 4
no read write execute = 011 = 2 + 1 = 3
no read write no execute = 010 = 2
no read no write execute = 001 = 1
no read no write no execute = 000 = 0
<http://www.websitebabble.com/uploading-files-ftp/1667-what-chmod-777-a.html>
I'll have a go in the next few days (will need to switch the HD's back to the new comp first etc) when I'm feeling brave.

Finder get info ignore ownership on volume vs wgm sharing perms

if I check "ignore ownership on volume" (finder > file > get info), how does this affect wgm sharing settings?
i.e. Is it ignored if WGM handles the share?
does it override wgm's settings?
just wondering how they interact with each other, if at all....
thanks in advance

The "ignore ownership" box in the Finder's Info window completely disables local POSIX and ACL permissions, making the affected volume act like a removable disk. (Any user assumes POSIX ownership of the volume with full control.)
If you want to use a volume to house a share point, do NOT check the ignore ownership box. Yes, you can share a volume with it checked, but with very unexpected results.
Often people have trouble sharing FireWire disks because they don't check to see if the "ignore ownership" box is unchecked before attempting to share them.

Problem moving Time Machine backup in Mavericks (missing "Ignore ownership on this volume")

In order to move Time Machine backup it is necessary to Make sure "Ignore ownership on this volume" at the bottom of the "Sharing & Permissions:" section is not checked.
However, this option has disappeared from Volume info window after upgrading to Mavericks 10.9.
Any idea how I can find this?
Thank you.

Once you're in the TM interface you will see a basically normal Finder window (with a lot of weird graphics, hence its other name The Star Wars interface )
On the right of the screen is the timeline allowing you to move backward and forward in time. Once you find what you want you can select the files or folders and restore.
As in the normal Finder multiple selections are allowed. I suggest you play around with it a bit at first and try restoring a file or a few files or folders just to get a feel for it.
good luck
regards

"Ignore Ownership" when backing-up CDs and DVDs

Dear members:
While in the process of making back-up copies of my applications' CDs and DVDs I was surprised by a message from Retrospect stating that if I proceeded to duplicate the disk with the option "Ignore Ownership" checked important files would not be copied that allowed the duplicate to be bootable.
Do any of you have experience with using Retrospect to duplicate CDs and DVDs ? Is this just a standard warning meant for duplicates of drives that have the operating system installed and that should be bootable copies ? Or could this affect my back-up copies ?
I would prefer to leave the option "Ignore Ownership" checked as it is my understanding that it would allow the disk to be read by other computers instead of only mine. Is this right ? Could my back-up copies become corrupted or unusable if I leave the "Ignore Ownership" box checked ?
Thank you in advance for your help,
Joseph Chamberlain

Hi, Joseph.
1. The "Ignore Ownership" warning is to ensure that you get a 100% accurate backup of the data you are backing up, including the privileges (Ownership and Permissions) associated with that data. Part of creating a 100% accurate backup includes backing up the filesystem information, such as the privileges associated with those files, not just the data files themselves.
This is covered in the Retrospect User's Guide: see the information concerning the "Privileges Warning" on page 162. You can also find this by searching Retrospect Help for "Privileges Warning" and selecting the topic "OS X Preference" from the search results. This warning can be disabled in Retrospect's OS X Preferences, but one should leave it enabled for the reasons stated above.
2. You wrote: "I would prefer to leave the option "Ignore Ownership" checked as it is my understanding that it would allow the disk to be read by other computers instead of only mine. Is this right?"No. For example, if you used Retrospect to Duplicate your Home folder to another folder on a FireWire drive, then connected that FireWire drive to a second Mac, you could simply select "Ignore Ownership..." in the Get Info window for the FireWire drive when its connected to the second Mac to have access to all the files in the duplicated folder on the FireWire drive. The "Ignore Ownership" setting is specific to the Mac using the disk/disc, not the disk/disc itself.
3. Retrospect is generally not the right tool for backing up CDs and DVDs of the type you describe. Retrospect is designed primarily for backing up data on hard drives. This is generally the case with all Backup and Recovery utilities. You could use it to backup CDs or DVDs that contain only data.
When backing up commercial CDs or DVDs there are a variety of other important issues to consider:
- The first are legal issues, such as "Does the software license permit this?" or "Is this activity legal in my country?" If the answer to either question is "No" then you should not engage in that activity.
- The second are formatting issues: while you may be able to backup the data and permissions bits off an optical disc, you may not be able to recreate a usable disc by burning the backup to another optical disc. For example, commercial DVDs generally employ some form of copy protection or encryption to prohibit or deter piracy. One can search MacUpdate or Version Tracker for specialized utilities for backing up various kinds of optical media so that one can create a usable disc, but one should not engage in these activities if they are illegal, either by license or by statute.
- In some cases, there are no legal restrictions, e.g. a home movie of your family that you filmed with your video camera and from which you created a DVD with iDVD or DVD Studio Pro. In this case you're the copyright holder. For that case, there are instructions in the AppleCare Knowledge Base: see "How to copy previously-burned DVD-R video discs."
Please note that all questions concerning Retrospect should be posted to the EMC Dantz Support Forums. These are like the Apple Discussions. Questions posted there are often answered by Dantz tech support personnel. Searching or posting to the Dantz forums are the best ways to find Retrospect answers quickly.
Good luck!

Give your previous partition layout, you cannot install Windows via Bootcamp, unless you are willing to give up all your extra partitions and go back to EFI, OS X and RecoveryHD only configuration.

1. Windows installer will not work and you will end up with driver issues.
2. No.
3. You cannot, but if you could, the Apple Bootmanager would be your Boot Manager/Loader.

K8N Neo fails to boot with more than one DIMM

I have been searching the forums for a while now, and will continue, but I am really hoping for a quick resolution. My system was running fine for over a year with a pair of PC3200 512MB DIMMs. I normally leave my computer on all the time. Recently I updated my BIOS to 2.10, and the system performed a soft boot afterwards. Christmas Eve day I knew I was going to be gone the whole day and probably not need my computer until late on Christmas day. I received a very unpleasant surprise.
I attempted to boot the computer up, and I got nothing but a repeating single long beep. I did a lot of troubleshooting and discovered that the system will boot and run fine with ONE DIMM, either DIMM. My system will no longer boot with a second DIMM in either the 2 or 3 DIMM slots. This is a major bummer for me, please help.
I have not played around much with memory timings and such as of yet. It is quite a pain to put in a single DIMM, and boot the system to make a BIOS change then shut it down again and install the second DIMM to see if it works.
Thanks in advance for any help.
Scott

Go back to your previous BIOS.
