This supports newer cameras and some other devices.<\/p>\n<ul>\n<li>MS-DOS ( FAT)<\/li>\n<\/ul>\n<p>MS-DOS (FAT) is the common name used and it can be useful for smaller SD cards and some older devices.<\/p>\n<ul>\n<li>Mac OS extended<\/li>\n<\/ul>\n<p>Mac OS Extended is used when the memory card is mainly used with Mac and it is not compatible with camera, game or other devices.<\/p>\n<ul>\n<li>APFS<\/li>\n<\/ul>\n<p>APFS is designed mainly for Apple devices and if you want to use an SD card for other devices then it is not suitable.<\/p>\n<h2><strong>SanDisk Memory Card Not Showing on Mac: What to Do<\/strong><\/h2>\n<ol>\n<li>Remove your SD card<\/li>\n<li>Insert again<\/li>\n<li>Try other USB port on Mac<\/li>\n<li>Use other card reader<\/li>\n<li>Check if Show All Devices is enabled in disk utility<\/li>\n<li>Test your SD memory card on other compatible devices<\/li>\n<\/ol>\n<p>If you follow all the steps but the SD card is not detected then it might be a hardware issue.<\/p>\n<h2><strong>How to Erase SanDisk Memory Card on Mac Using Terminal<\/strong><\/h2>\n<p>The Terminal process gives more control than Disk Utility, but you have to focus more because selecting the wrong disk can erase data from another drive also.<\/p>\n<p><strong>1. Open Terminal<\/strong><\/p>\n<p>Go to <strong>Applications &gt; Utilities &gt; Terminal<\/strong>.<\/p>\n<p>You can also open Terminal by pressing <strong>Command + Space<\/strong> and searching for Terminal.<\/p>\n<p><strong>2. Find the Memory Card<\/strong><\/p>\n<p>Type the following command in Terminal:<\/p>\n<pre><code>diskutil list<\/code><\/pre>\n<p>Then press <strong>Return<\/strong> and find your SanDisk memory card by checking its size and name. Make sure you select the correct disk before running the erase command.<\/p>\n<p><strong>3. Erase and Format the Card<\/strong><\/p>\n<p>For example, you can use the following command:<\/p>\n<pre><code>diskutil eraseDisk ExFAT SANDISK MBR disk4<\/code><\/pre>\n<p>You can replace <strong>SANDISK<\/strong> with any name you want to give the memory card.<\/p>\n<p>If you need a compatible smaller card using FAT32, you can use the appropriate FAT format supported by your macOS version.<\/p>\n<p>This Terminal method can be a good option when you want to erase a SanDisk memory card on Mac.<\/p>\n<h2><strong>Problems With the Manual Method<\/strong><\/h2>\n<p>Mac built-in method is useful but it has some issues and these are some common issues with manual methods<\/p>\n<ul>\n<li><strong>Secure erase option may be limited<\/strong><\/li>\n<\/ul>\n<p>The erase option in Disk utility may depend on your Mac OS version and storage type.
