If I understand your question correctly you are trying to resize the volume group or actually one of the volumes within a group. From what I could gather your disk was converted to a CoreStorage Volume. Could you please verify that by issuing the following command in a terminal and check if you get a similar output to the one in the picture: diskutil ...

This is how to fix the bootcamp windows install error: "Windows could not update the computer's boot configuration." Do not try to fix with a workaround - you'll find solutions of people manually selecting their Windows partition during reboot by holding down the OPTION key. This will work, but you are circumventing the way that apple wanted you to install ...

Yes you can repartition without losing data. Using Disk Utility, perform a repair on your drive to make sure the drive is free of errors (even better, use Diskwarrior if you have a copy). Then unmount your drive but don't eject it. Select the drive in the left hand pane, then go to the Partition tab. On the Partition Layout section click on the "+" to create ...

The Mac hardware stores the boot volume in NVRAM so you could power off the computer and then reset things by holding the Command Option P R keys down. Once you've heard two boot chimes you can release things and if the Mac OS X volume is viable it will boot first. If that doesn't work then it's likely that the OS X volume has issues and the system is ...

If your partition turned into Logical Volume Group (you can't resize or delete Yosemite partition), you can revert partition type with few command line. Open Terminal type "diskutil corestorage list" Find Yosemite partition UUID string. type "diskutil corestorage revert " Your Yosemite partition is now revert to default partition type. Now, you can resize ...

I also asked on the developer forums and got an answer there (iOS/OS X dev account required to view). The solution was to boot into a recovery partition (⌘ + R), and change the boot disk from the Apple menu. It needed to be changed to my Mavericks install instead of my Yosemite install.

According to this page: http://support.apple.com/kb/PH11102 If the Encrypt checkbox is available, you can select it to keep your backup disk secure. If the Encrypt checkbox is dimmed, your backup disk doesn’t support encryption. Encryption is available only for Time Capsules and for partitions or disks attached directly to your computer and ...

Have you tried holding down the option key when you reboot? You can also select the default boot disk from the bootcamp GUI in windows.

It is definitely possible to partition a single drive into two partitions and have separate encrypted Time Machine backups on each partition for your two individual Macs. The only downside is a single point of failure since there's a single physical drive used for two machines. If anything goes wrong with that disk, both the Macs would be left without ...

I've struggled for some days with the same problem but now it is solved. The problem was a faulty SATA cable. I've replaced it with a new one and now everything works as expected.

I also have this issue... MacPro, 3TB drive (Seagate). I have to use the terminal: diskutil list diskutil unmount /dev/disk22 diskutil eraseDisk HFS+ "Macintosh HD" /dev/disk22 etc etc to utilize this drive correctly. (Sorry for all the commands. Posting them just in case it helps someone. Though anyone using those commands better know what they do ...

Your partition table does not know about the larger hard drive yet. While Disk Utility also queries the hard disk size and lets you request it to enlarge your partition, it will fail when finally changing the partition size (after doing a file system check). This can be solved on different ways: One is to destroy the GPT (partition table) and recreate it ...

You can use diskutil cs list to show the core storage view of things. Once you have the logical volume UUID for the disk in question, you can use diskutil cs deleteVolume to clean up the reserved space that was allocated to the encrypted data and filesystems. That would allow you to surgically remove the core storage. You could also unmount the filesystems ...

A virtual install of OS X Lion runs without issue on Mavericks. All the popular VM software understand Lion as an OS and should let you install it. I don't see you having any problems with this setup as long as your hardware is Mac.

Yes! As the disk is the correct format, it will show in the disk list in the installer (click Show All Disks). You can install any version of OS X on a partition of the correct format, regardless of where the partition is located. The OS X installer doesn't partition the disk for you though; do this first in Disk Utility.

You can't use filesystem commands (cp, mv, ls, etc.) on devices (/dev/*). If you want to copy everything, bit-for-bit, from volume to volume, you'll need an app like Super Duper or Carbon Copy Cloner.

I highly recommend completely backing up the machine before attempting this, either using TM with no exclusions set, or better yet, cloning the whole drive using a program like Carbon Copy Cloner. Unmount the Logical Volume: sudo diskutil unmount force /dev/disk1 Remove the Logical Volume Group and all of its contents: sudo diskutil cs deleteLVG ...

It seems that i did it using this post Unable to Resize Partitions and your comment. Although it wasn't obvious for me, what I did was this: diskutil corestorage resizeStack LOGICAL_VOLUME_UUID 0G 0G to expand it to the maximum available space that is free. diskutil corestorage resizeStack can provide with info.

The following diskutil cs resizeStack command is vastly undocumented and as such potentially destructive. There might be an easy way outlined first and a long winding, time consuming hard way. Please backup your Mac OS X before proceeding. The not-as-long-as-expected way: A 2nd computer or an iPhone with the stackexchange credentials to enter the site ...

I have never, and I mean never, even back to the "classic" Mac O/S days (going back to system 6) partitioned a drive into smaller chunks. Performance gains were supposedly about different parts of a rotational drive being faster than others (EG quicker seek to sectors near the physical hub). There may also have been some O/S speed gains in some O/S if you ...

Wait, before you do that, you can do this in an easier fashion. Just shrink the Mac partition via Disk Utility and format the new free space as FAT32.

The process for creating an extra partition in Mavericks hasn't changed much since Snow Leopard, so you should be able to create a partition using Disk Utility the same way you did in Snow Leopard.

The recovery partition for OS X 10.7 and above includes the following utility applications: Firmware Password Utility Network Utility Disk Utility Terminal In addition, the recovery partition allows you to use a version of Safari to better help you research and diagnose problems, restore from a Time Machine backup, and install OS X.

The phenomenon derives from a faulty Apple Script mounting a Time Machine sparsebundle image from a smb-share serving as a Time Machine backup volume to /Volumes. The mounted image interferes with (maybe any) other mounted volume(s) there The faulty Apple Script: try mount volume "smb://someserver/DATA" end try do shell script "/usr/bin/perl -Ue ...

I had the same issue since the beta and the official release did not solve this issue. In the terminal I had the following output: diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *251.0 GB disk0 1: EFI EFI ...

sudo bless --folder /Volumes/yourdisk -label "Title here" bless is the command to set startup disk options. --folder specifies the disk and -label assigns it a label.

I would use the terminal to sort things out if you don't see what's happened in Disk Utility. diskutil list From there, you can see all the names and numbers OS X has given to the volumes/partitions. Eject them all (except for the booted OS). diskutil eject disk2s2 etc... At that point, you might need to clean up the bad mount points. ls -l /Volumes ...

I had a similar problem. I created a 30 GB partition and after deleting it there was unused space. I couldn't manually get the original full partition back because of disk errors. So I booted into Recovery (Command + R), repaired the disk with Disk Utility and then the resize to original was no problem. Rebooted and now back to normal. Had no need to ...

You can use the same folder for Mac and Windows versions of iTunes. I would recommend use the exactly same version though. Here is more info on how use it through the network: http://hints.macworld.com/article.php?story=20070424081346722. It's the same logic, but you will be using the same local folder instead a network shared one.

This requires the three partitions between the selected one and the intended one to be moved. Disk Utility can't do this without destructively destroying and recreating the partitions in the intended location, removing all data from the partitions. You will need third-party software such as iPartition. For more information, see Partitioning Software.
