I have heard rumor that Deploy Studio can act as a BSDP server (Apple’s netboot protocol), but it is also a bit overkill for what I need. We have a number of NetInstall images and a single “thin-client” image for System Diagnostics (has a few helpful utilities).

Open Restore From Time Machine Backup and restore your data.So in my continuing deletion of all things Apple Server, I am tasking myself with also getting rid of our BSDP NetBoot server for Mac clients. To revert to the old-style volume delete the Logical Volume Group instead of modifying the CoreStorage stack:Įnter diskutil cs delete LVGUUID with LVGUUID = UUID of the Logical Volume Group found in one of the previous steps.

You need a full Time Machine backup of your main volume though. I recommend to revert to the old-style partition scheme before installing Linux with Grub/rEFInd.

Now you have ~(250 GB - size) GB of unallocated space and may install Linux.

Open Disk Utility and check your shrinked CoreStorage volume for errors.

Your Recovery HD should be moved automatically - regardless of whether shrinking or expanding the CS volume - to the very end of it (right after the CoreStorage volume). To expand it to the full available size (0g is a magic number here). With LVUUID: UUID of the logical volume and size: the final size of your CoreStorage volume.Įxamples: diskutil cs resizeStack 86417B41-6400-4F81-8F7C-43AA243CDAEE 200g Resize the CoreStorage volume with diskutil cs resizeStack LVUUID size belong to the OS X Base System (your recovery system you booted to previously)ĭisk0 is your main internal disk device (SSD) containing an EFI-partition (dis0s1), one CoreStorage partition (disk0s2) and Boot OS X (disk0s3).ĭisk1 is a logical disk created by booting to the netboot image which contains a recovery system (OS X Base System = disk1s2) similar to the Recovery HD.ĭisk2 is also a logical disk residing in disk0s2 and it contains the CoreStorage stack.Įxample listing: CoreStorage logical volume groups (1 found) So check the human readable names and sizes and change the commands below accordingly.įirst you should get an overview of your disks and the partition layout:Įxample listing (but I took the list provided by you in your question and included the netboot device): /dev/disk0Ģ: Apple_CoreStorage Macintosh HD 249.1 GB disk0s2ģ: Apple_Boot Recovery HD 650.1 MB disk0s3Ģ: Apple_HFS OS X Base System *1.3 GB disk1s2Ġ: Apple_HFS Macintosh HD *249.1 GB disk2 If you are restricted to WIFI and the boot process fails, just restart your Mac until you succeed booting.Īlternatively you may start from a bootable installer thumb drive (Mavericks or Yosemite) or a thumb drive containing a full system (Mavericks or Yosemite). I recommend ethernet because it's more reliable. On a 50 Mbps-line it takes about 4 min (presenting a small animated globe) to boot to a recovery netboot image which usually is loaded from an apple/akamai server.

#HOW TO NETBOOT A MAC YOSEMITE UPDATE#

The prerequisites are the latest firmware update installed, either ethernet or WLAN (WPA/WPA2) and a router with DHCP activated. Restart to Internet Recovery Mode by pressing alt cmd R at startup.

Detach any external drive (especially your external Time Machine backup drive).

The command expands or shrinks the whole CoreStorage Volume Group including the physical volume(s), the logical volume family and the logical volume in one step to the desired size.īeware: The command is vastly undocumented and as such potentially destructive.

To shrink your CoreStorage Volume Group to get some unallocated space to install Linux or EFI-Windows just use an undocumented diskutil command: diskutil cs resizeStack LVUUID size You shouldn't use Disk Utility to modify the CSVG. Essentially you have a CoreStorage Volume Group instead of an old-style partition scheme.
