There are many ways to back back up your Pi’s SD card, but I have found this one the easiest to remember how to do only doing it once or twice a year since it uses Disk Utility.
If you haven’t given Disk Utility “Full Disk Access” You will need to do these steps only once.
- Step 1: In your Preferences go to > Security and Privacy > Privacy
- Step 2: Hit lock button and enter password
- Step 3: Hit the
disk utilityand add, save and close out
Once that is done backing up is easy and can be done with only a few clicks.
- Step 1: Open Disk Utility, hit **
⌘2**so all disks are shown
- Step 2: Right click on the top level volume of the SD card you want to back up and select
Image From ....
- Step 3: Name the file what you want but before you save change the format from
read/writedepending on your needs.
That’s it folks! 3 very quick steps to backing up your Raspberry Pi SD card on a Mac! With the ISO file you can easily use Etcher to deploy the image on other Pi’s or replace a worn out SD card.
I hope you find this helpful!
