Checking SD card integrity/Mac/legacy

This is an add-on section for checking your SD card for errors using F3X.

Depending on the size of your SD card and the speed of your computer, this process can take up to several hours!

This page is for Mac users who are using macOS Sierra (10.12) and earlier. If you are not on macOS, check out the Windows or Linux.

If you're using a Mac on macOS 10.13 (High Sierra) and above, follow this page instead.

2. Insert your SD card into your computer
3. Run the F3X app
4. Select your SD card
