After formatting, none of the files are left on the SD card. So it is recommended to take back up before initiating the formatting of memory card. This helps in restoring essential files to the SD card.
Part 2- How to Format Memory Card on Mac Safely
Some of the Mac systems have an in-built SD card slot; here you can directly insert an SD card to access it from Mac. If the SD card slot is missing in your Mac, then you can also use a USB card reader. For micro SD cards use SD adapter cartridge to put the card into the slot of Mac. Once you are ready with your SD card for formatting, follow these easy steps to format and make it reusable.
Step 1- Connect SD card with Mac
Insert the card into the SD card slot or connect it with a USB card reader.
Step 2- Open Disk Utility
Disk utility is in-built in Mac. Use the spotlight or follow the following path to reach “Disk Utility” Applications > Utilities > Disk Utility
Step 3- Locate SD Card
Find your SD card from the left sidebar of Disk Utility. It shows the Mac’s internal as well as external drives. You can see your SD card in the external section. If your card is never formatted before it shows up as “Untitled” or “No Name.”
While selecting the memory card, double-check it that you are choosing the right Drive from the list. Click on it to view the storage space and ensure that your inserted SD card’s memory matches the one that is showing up. If you see some mismatch then probably you have selected the wrong drive. Carefully make the selection again in this case.
Step 4- Click on Erase Tab
Select the “Erase” label located at the top in the menu bar of Disk Utility. When you click on it a pop-up will appear to warn you that you are going to delete all the files saved on your card.
Step 5- Write SD Card Name
Name the SD card as shown in the image below and select the format of the file system. The ExFat format is generally compatible with SD cards.
It’s not mandatory to name the SD card here; you can leave it as “No Name” or “Untitled.” Naming it will only act as a convenience to you at a later stage when you view it in “Finder” or while importing things.
The file system here is dependent on the size of the card. Like if its storage capacity is 64GB or more than that, select ExFat and if it’s 32 GB or lesser than select FAT32.
Step 6- Click Erase
After naming and selecting the format of the SD card, click on the button displaying “Erase.”
Step 7: Click Done When “Erase” Completes
When the formatting completes a message saying the process is complete, display on the screen.
Once the format completes, the SD card is visible in the Disk Utility drive list and also in the Finder menu. Eject the SD card and use it in your device.

Part 4- Tips for Formatting and Format Recovery on Mac

- Keep your SD cards healthy to avoid formatting. To maintain them, start using the SD card after formatting it once and never let them completely filled. Prefer using only branded cards and don’t turn off the device while it is writing data; this can damage the card.
- Go for reformatting the card over deleting the content from the card. If you go with reformatting, it keeps SD card in good working conditions for extended times. It is advisable to erase or format unwanted files by using Mac.

USB port types and names
USB (Universal Serial Bus) is an industry standard for connecting computers and other devices. It's available with many types of ports, and each type has a unique shape. On Mac computers, USB is available with these ports, depending on your Mac model:
USB-A
Type USB-A ports are commonly called USB, USB 2, or USB 3 ports, depending on the USB specification they support. They aren't reversible, so a USB-A connector plugs into the port only when oriented correctly.
USB-C
Type USB-C ports are available as either standard USB-C ports or Thunderbolt 3 ports that also support USB-C connections. They both look the same, and the connector plugs into the port in either orientation.
Learn more about identifying the ports on your Mac, as well as the adapters and cables you can use to connect older devices to type USB-C ports.

USB specifications
USB specifications are important primarily when you want the most speed and power for your USB device, or your device needs more power or is using too much power. Every USB port supports a particular USB specification, which determines the port's maximum>USB specifications on MacData transferPowerUSB 3.1 Gen 2

Get the best performance from your USB devices
Usb For Mac And Pc
USB specifications all work with each other, but speed and power are limited by the cable or device that uses the earliest specification. For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it can't draw more power from the port than can be delivered over USB 2. In other words, to get the best performance, make sure that the USB port on your Mac and the USB cable to your device meet or exceed the USB specification of the device itself.
If your Mac doesn't recognize a USB device after you plug it into your Mac:
- Check all connections: Unplug the device from your Mac, then plug it back in, and make sure that all cables and adapters are securely connected at both ends. Test with another cable or adapter, if available.
- Plug the device directly into your Mac instead of a USB hub or other device, and if necessary test with a different USB port on your Mac or device.
- Some devices need their own software, such as drivers or firmware. Others work without additional software. Check with the maker of your device, and install all available Apple software updates as well.
- If your device came with an AC power adapter, use it. Some devices can be powered by the USB port on your Mac. Others need more power than your Mac can provide.
- Restart your Mac.
