I have a brand-new 2021 M1 MacBook Pro running macOS Ventura. However, my computer can’t read or recognize any SD card, regardless of whether I use an adapter or an external card reader. How can I fix it?
You can try disconnecting the SD card and restarting your Mac. If the issue is related to system software or hardware connection problems (such as a driver not loading correctly or a minor system glitch), restarting your Mac may reset the USB or SD card reader connection, allowing the SD card to be recognized properly.
You can do it by removing the SD card > restarting your Mac > reinserting the SD card. After that, check if your Mac can now recognize the SD card.

The fastest way to fix your unreadable SD card is to format it. However, you should know that formatting will erase all data on your SD card. Therefore, it is recommended to recover your data first using iBoysoft Data Recovery for Mac before proceeding with formatting.
I have used this software before, and it recovers data quickly with a high success rate. Download iBoysoft Data Recovery for Mac, simply connect your SD card to your Mac, follow a few easy steps, and your lost data can be recovered.
Once you have recovered your SD card data, you can go to Finder > Applications > Utilities > Disk Utility to format your disk.
