How to Fix SD Card Reader Not Working M1 MacBook Pro 2021

My SD card reader will not read/show on my M1 MacBook Pro 2021. I've checked the Finder settings to make sure it's showing the SD card. None of my cards are corrupt, but this issue happens on all SD cards. Is there any way to fix this?

Suppose you face the issue of SD card reader not working M1 MacBook Pro 2021. Don't worry. According to the feedback of most Mac users, the SD card not detected on Mac issue mainly affects 128 GB SD cards under numerous brands of SD cards.

But no matter how big the storage space and what the brand of your SD card is, you can refer to the following ways below to fix the problem:

Fix 1. Format your SD card: the SD card not reading on Mac issue may be caused by the formatting glitch, so formatting the unworkable SD card can solve this problem.

Note that if you want to retrieve the essential data/files from the formatted SD card, I'd like to introduce a data recovery tool, EaseUS Data Recovery Wizard for Mac, which can help you make SD card recovery on Mac with a few clicks:

Step 1. Select the formatted SD card partition.

Step 2. Click 'Scan' to view all your lost/deleted data and files.

Step 3. Click 'Recover' and save them in a new location.

Fix 2. Change a USB-C SD card reader: this is an unstable solution: some users use this method to read the SD cards on their Macs successfully. But some users give feedback that this method is not useful.

Fix 3. Use an SD card reader dongle: this is not an ideal solution that exactly solves the SD card not working problem, but it provides a way to access the content on your unreadable SD cards on M1 Mac.

Fix 4. Update your macOS: Apple said they were aware of this issue and will fix it in the following update, and some people reported that installing macOS Monterey had fixed this problem.

Use EaseUS Data Recovery Wizard to recover deleted or lost files easily and quickly.
