I was reviewing some training material I put together today related to imaging MacBook Pro and MacBook Air laptops. I wanted to create a simple decision tree for the common scenarios when encountering Mac laptops. The basic breakdown was this:
- Remote imaging (really only used in corporate environment)
- Using SSH/SCP to load and start agent
- Locally imaging
- Target Disk Mode (easiest)
- Booting to external OS (CDROM or external hard drive) Used when device does not support TDM.
The simplest solution seems to be a large external drive that has a bootable OS on a small partition, but then a large second partition (FAT32 or NTFS) that can be used to hold the image.
Boot the MacBook Air by holding down the "option" key and selecting the listed bootable external drive. Once booted, you could use an imaging tool for that OS (OSX or linux) to image the internal drive to the external drive.
This solution only requires a single USB port and seems to be the simplest method. Although I would recommend using a powered external drive, this should work with a bus powered USB external laptop drive as well.
Aside from pulling out the internal drive, I would be interested in hearing what other people are doing or have found to be the quickest/safest/most efficient way?
