This should be one way to regain your unused space. There might be a better (or more elegant) solution, but since i don't have a spare Mac at the moment (and it doesn't work in a virtual environment) i can't figure that out. The solution outlined here removes any partition which obstructs the expansion of the CoreStorage Volume Group. Then the physical ...

I agree with your assessment of the situation. There is rampant inconsistency in dual-boot installation instructions, all of which contain glaring errors. Careful notes are not being recorded or the procedures are just being made up out of thin air or recollections from work done months ago. The confusion is not being caused by anything Apple is doing but ...

If you've installed Yosemite it will automatically have created an invisible recovery partition and so you may as well delete the recovery partition you created. Keeping a copy of the Yosemite installer on a USB stick is definitely a good idea though in case your drive ever dies or you need to perform a clean install (on an SSD for example). Alternatively, ...

go to the partition, mine was named disks03, i then went to the ERASE tab, then select security options, here i raised it to the max option which said something about the standards of U.S department of defence. once you've set the security option to max, hit erase, and it begins the purge! Worked fine for me

The problem turned out to be the PMBR. My first attempt was to copy sector 0 off a GPT formatted memory stick. Examined that with fdisk and it had partition of type EE, but start and end cylinders were the same. I edited partition 1 and accepted defaults. fdisk on mac will report "can't get exclusive access to write sector back, reboot required" It ...

I tried everything from apple.stackexchange and other blogs but none worked. But this method worked like charm: Make a bootable Windows USB using bootcamp. Do not partition or download support files. Restart your comp holding "option" key. Open Windows partition and keep clicking next until you have to choose to format a disk. Choose the block with the ...

I recieved "Partition map check failed because no slices were found.” from Disk Utility but perhaps for different reasons. I had to reMOUNT (either it's a "right-click" or a button) the partition from Disk Utility and then Repair the partition. Then it worked - heart attack / data loss averted.

I had the same problem as you, and i searched all the forums and i found that if you turn off FileVault it should work.

I remember having this issue as well when I tried using bootcamp. I seem to remember that it was due to a fragmented drive that didn't have enough contiguous space to create the partition of the size I was requesting. From memory, it was a bit of a pain and I think I ended up partitioning the drive first, then reinstalling OS X on one partition and using ...

You will need to create an installable USB drive which you can boot from, follow these steps carefully to achieve that: Download the Mac OS (Yosemite) from the App Store Format a USB in Disk Utility and name it Untitled (very Important) You should format your USB to Mac OS X Extended (Journaled) launch Terminal and type or copy and paste this command ...

As mentioned by the other comments, Apple's default partition scheme is to have everything on ONE partition. While not recommended (potentially due to not being easy to do), it is possible to move a home folder to a different partition. Here is how: Create a partition to use for the home folder (Disk Utility is the built-in choice to do so) enable the ...

To delete CoreStorage volumes you have to use the CLI: please backup your volume "mainHD" boot to Internet Recovery Mode (hit altcmdR immediately after the start-up chime) open Disk Utility and check/repair mainHD quit Disk Utility , open in the menubar Utilities/Terminal.app and enter diskutil cs deleteVolume LVUUID to delete the Logical Volume in your ...

You can't move the start block (=380677208 for LVG2 or "Macintosh HD 2" in your case) of a CoreStorage Volume (Group) non-destructively. The same is valid for non-CoreStorage partitions with on-board tools. AFAIK for the latter only iPartition and gparted work. Therefore you can't easily reclaim empty space with a lower start block and an arbitrary size and ...

Probably your Boot Camp partition is hosed and couldn't be removed simply. So i would try to reinstall Windows 7 with your pre-made (Microsoft's bootable USB creation tool!) thumb drive. Attach the Windows 7 installer thumb drive to your Windows server, format it if necessary (FAT32) and create the bootable Win7 install thumb drive again with the ...

If you're asking what I think you are, simply click and drag the bottom right hand corner of the blue 'Macintosh HD' partition downwards to reclaim the space you've free'd by removing the Ubuntu partition. You don't need to reinstall OS X.

There is nothing that you do about this other than try to hide them. It occurs because one file system doesn't support extended attributes. There have been quite a few posts on the dropbox forum and I suggest you file a bug report with dropbox. They'll claim it is normal behavior but they still need to find a fix.

As for the Yosemite bootable disk, it should be possible to make one from the Yosemite installer app - Be sure that you have downloaded it, not installed it. I think 8Gb should be enough actually. For the stubborn Partition, I like to use Linux for this. Any Linux Distro should be suitable, because it has GParted most of the time. Format the stubborn ...

If the machine still boots, go to the App store and "purchase" Yosemite (its free). Now boot the machine holding COMMAND R and boot to internet recovery. If you see a poorly animated spinning globe instead of an Apple logo then you are on the right track. Now you have can reformat the whole drive and do a clean install of Yosemite.

UPDATE: There are three partitioning schemes used by both Windows and OS X. The first is MBR, which has been around since the 1980’s. The second is GPT, which is fairly new. The third is a hybrid scheme which combines the first two. OS X’s Disk Utility application allows you to select either MBR or GPT. If MBR is selected, then you get the traditional MBR ...

You cannot resize the active partition. You need to boot into Recovery Mode which will let you and resize the main partition. Select the whole drive then the Partition tab. http://support.apple.com/en-us/HT4718 PS Make sure you have a Time Machine backup before doing anything.

Update 2: I assume OS X is installed on partition 2 of disk 0. If you want me to check this, then post the output of the next three commands and I will verify. Otherwise proceed and attempt the resize. diskutil list sudo gpt -r -vvv show -l /dev/disk0 sudo fdisk /dev/disk0 To resize to a smaller size, you will have to boot using OS X Internet Recovery. ...

Can you select the free space partition then hit the minus (-) button to delete it? You'll probably need to try that, then see if you can drag the border of the main partition to resize, then hit the plus (+) to create a new partition. Nothing can use the free partition, so it won't hurt to try deleting it.

It looks like you manged to delete a Hidden partitions. One is Called EFI and it is about 200mb. The second one is called RecoveryHD and it is about 600mb. There was a reason for them to be hidden, but if you have the Debug menu show all on, they will show. The good news is your data is still there, if you did not do further damage. If you have a ...
