To recover pictures from a formatted SD on Mac:
You have two options for recovering deleted files from a Micro SD card for free. The first is to check the device that contained the card for a Recently Deleted folder. Many devices include this feature to minimize the damage of accidental deletion. The other option is to recover the files from a previous backup of the card’s data.
In this kind of situation, you need to find a way to get the microSD card recognized by your system so you can use data recovery software. Try accessing the card in a reader or alternate device. If that fails, you may need to use Disk Management and format the card to make it readable. Your data may be lost.
