Can anyone help me/direct me on how to do this in a proper manner? It seems that for the image to work correctly, it must come from an identical unit meaning a unit that has the same specs. My actions were actually a practice run to re-image 30 Late model 2015 iMacs (specs seen below). The system on unit 2 runs, but seems to be a bit sluggish. I cloned an image from unit 1 (specs seen below) via Time-Machine and re-imaged unit 2 (specs seen below) using the clone from unit 1. Click on the вЂњRestoreвЂќ and вЂњEraseвЂќ button. Drag the first вЂњMacintosh HDвЂќ into the вЂњDestinationвЂќ box. Double-click on the bottom вЂњMacintosh HDвЂќ. Double-click on your dmg and click вЂњSkipвЂќ. Click on the вЂњImageвЂќ button and choose your dmg file. Choose your hard drive on the left-hand side. Plug in your external hard drive to your computer that contains the dmg file. Hold down the Option key during the restart of your computer.

Plug in your external hard drive and upload the dmg into it. Name your dmg file and save it to your desktop.

Open your Disk Utility application and click on the вЂњNew ImageвЂќ icon. Imaging your computer is also a great way to back-up your important data.ДЄll this could not have been done with the help of Jacob in the IT department. The hard drive I cloned, or imaged, included the specific applications I wanted my students to use, specific OS settings, and numerous Chrome extensions that block inappropriate ads on the browser. This process involved the cloning of a computer hard drive that I customized and reinstalling it to the rest of the computers. I wanted to start the school year with a new clean slate by re-imagingВ my computers in the lab.
