5. Mount SD Card in Disk Utility
Mounting an SD card or external hard drive in macOS makes the storage device available for read and write operations. This process is usually automatic when inserting the device, but if not working properly, you can manually mount it using Disk Utility. To do this, follow the steps to make the storage device recognizable.
Step 1. Open Disk Utility, select SD card on the left pane.
Step 2. Click the Mount button on the top.
Step 3. Close the window, check if your SD card shows up.
6. Reset NVRAM/PRAM
If your Mac experiences an unexplained issue, you may be advised by Apple's customer service to reset NVRAM or PRAM. These terms refer to two types of memory that store settings and data on your Mac. NVRAM (Non-Volatile RAM) is a small amount of memory that retains settings even when the power is turned off, while PRAM (Parameter RAM) is a type of memory that stores settings that are specific to the hardware and are lost when the power is turned off. Resetting either of these can sometimes resolve issues with your Mac's performance or functionality.
NVRAM, short for 'nonvolatile random-access memory', is a small amount of memory that your Mac uses to store certain settings and access them quickly, storing similar information as PRAM, which is also called Parameter RAM. The steps for resetting NVRAM and PRAM are the same.
Step 1.To reset your Mac, shut it down, then turn it back on and press and hold the Option, Command, P, and R keys simultaneously. This will initiate the recovery process and allow you to restore your Mac to its factory settings.
Step 2. Hold the keys for about 20 seconds, and your Mac might appear to restart.
- On Mac computers that play a startup sound, you can release the keys after the second startup sound.
- On Mac computers with the Apple T2 Security Chip, release the keys after the Apple logo appears and disappears for the second time.
