How do I create a bootable drive from and existing OS intallation
re this thread: How do I create a bootable clone of OS on… - Apple Community
The volume on device "/dev/disk0" is not of type Apple_HFS or Apple_UFS
Could not validate source - Device not configured
The operation couldn’t be completed. (OSStatus error 6.)
I have tried this in the past and also have received this error message.
In the posting to the community that I am referencing the error was not
addressed.
So what is the problem and how do I fix it?
I have an older (ca 2008) Macbook Pro 15" that has Yosemite installed.
The internal drive has started making rattling noises that sound like
it is about to die.
SO;
I want to copy the system to an new drive, probably an SSD drive that
can replace the internal drive. It has Mac software with features that
were removed in later versions.
Yes I have done lots of work on Macs including Powerbooks and Macbook Pros.
They were user serviceable, unlike many newer models.
Thank you for time and attention
MacBook Pro 16″, macOS 26.0
