MAC-OS cloning23 May 2017
Recently I had a task to clone the Mac OS operating system with some pre-installed software to other Mac Pro computers with almost same hardware configuration. To do it directly (Install OS, Install all necessary software) to every unit takes a lot of time. So, I have decided to install one unit and after clone it to other ones. Here I will describe the methods I have used.
The Windows platform has the own utilities which helps to clone and backup the system to other hard drives. As for me I prefer don’t use the third party utilities for system administration if native system tools exists. The other words I don’t trust the third party tools for such type of tasks. The Mac OS has such tools also, but they are command line. ;)
As I wrote above I prefer to use native command line tools. Here is HOW.
First check the disk identifier by
Then create the DMG image by:
mySystemImage.dmg- the name of image I try to create
disk0s1- the device name I try to clone
Later if I want to restore the image this command will help:
mySystemImage.dmg- the name of image I try to restore
/Volumes/MacOS- the name of fresh formatted hard drive
noverify- skips verification after restoring
erase- erase the target volume before continuing
That’s all for today.
If any questions let me know in the comments below. Have a good day…
