I need to flash my image from sd card to sd card (using an usb adapter). The problem is my cards full and I have a bigger card but can’t back up to the Mac as I’m out of storage on the hard drive
Hello @Chilli - welcome to the forums. Yes, there is a clone mode in balenaEtcher that can clone a smaller drive (e.g. Micro SD Card) to a bigger medium. Smaller to bigger is not an issue, the other way around is problematic. You will probably need to resize the partition on the cloned drive afterwards with other tooling to make the whole space available / useable. However, you will really need to take care that you do not write the SD card content to e.g. your Macs storage/do not accidently overwrite it.
