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, USB is available with these ports, depending on your Mac model:
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.
Type USB-C ports are available on Mac as standard USB-C ports, Thunderbolt 3 ports, and Thunderbolt / USB 4 ports. They all 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 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 transferPower deliveryUSB 4Up to 10 GbpsUp to 15W at 5VUSB 3.1 Gen 2

To learn which specification is supported by a type USB-A or type USB-C port on your Mac model:
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:
Nowadays, when you buy a USB drive, you can use it right out of the box with your Mac. However, unless it’s been designed for use with a Mac, it won’t be formatted using macOS’ preferred file system (either Mac OS Extended or APFS, depending on which version of macOS you’re running).
That’s because most of the computers in the world run Windows, and Windows uses a different file system, usually one known as Fat32. Drives formatted as Fat32 can be read from and written to by macOS, but it’s not optimal and you’re more likely to run into problems than if you use macOS’ native format. So, if you’ve bought a USB drive that’s formatted as Fat32, or any other format other than Mac OS Extended (also known as HFS+) or APFS, here’s how to format a USB drive on Mac. It’s exactly the same procedure if you need to reformat a flash drive on a Mac.
1. Plug the drive into a USB socket (if you have a recent MacBook or MacBook Pro that only has USB-C connectors, you’ll need a USB-C to USB-A adaptor).
2. Open a new Finder window and click on the drive. Make sure it has no files on it that you need. The process of reformatting it will wipe all the data from it.
3. Once you’ve copied any files you need from the USB drive to your Mac, go to Applications>Utilities and double-click on Disk Utility.
4. Click on the USB drive in the sidebar and then choose Erase from the toolbar at the top of the window. Best free pdf printer for mac.
5. In the window that drops down type a name for the formatted drive in the box next to Name.
6. Choose a format from the dropdown menu.
7. If you have previously stored sensitive data on the drive, click the Security tab.
8. Choose a security level using the slider. The further to the right you move the slider, the more ‘passes’ the erase tool will make and the more securely files will be deleted. However, it also increases the time it takes to format the drive quite considerably.
9. Click Ok then click Erase.
Tip: You don’t need to erase a whole drive to delete files securely. If you have confidential files or sensitive data you need to remove from your Mac completely, you should use CleanMyMac’s File Shredder. It’s specifically designed to securely delete sensitive data and will render it unrecoverable. Clownfish voice changer mac download. You can download CleanMyMac X for free here.
If your Mac is running macOS High Sierra or later, you have two options for file formats: APFS and Mac OS Extended. Which should you choose? The key point is that disks formatted as APFS won’t be recognized by Macs running versions of macOS older than High Sierra. So if you think you might need to plug the USB drive into a Mac running an older version of macOS, format it as Mac OS Extended.
APFS is optimized for SSD (solid state drive) such as flash drives, so if you reformat a flash drive on a Mac, you should definitely choose APFS (unless you plan to use it with a pre-High Sierra Mac, of course). Even on hard drives, however, APFS is faster and more reliable than Mac OS Extended.

Time Machine can’t currently back up to an APFS disk and if you select one for use with Time Machine, it will offer to reformat it as Mac OS Extended. You can, however, backup an APFS formatted disk to a Mac OS Extended Time Machine drive.
The main reason for formatting a USB drive as Fat32 on a Mac is that you want to be able to use the drive on a Windows PC, as well as a Mac — perhaps to transfer files between the two machines. You may also be preparing the drive for use as, say, a storage device for a media player or to record TV programmes on a TV with a USB port.
The fact that Fat32 can be read from and written to on both Mac and Windows makes it very versatile. However, there is a significant limitation — individual files have a maximum size of 4GB. So, if you’re using the USB drive to store large video files, you may run into trouble. There is a solution, however, exFAT. Unlike FAT32, exFAT doesn’t have a maximum file limit. Better still, it can be read from and written to on any Mac running Mac OS X Snow Leopard or later and on Windows.
To format a USB drive in FAT32 or exFAT:
1. Plug the USB drive into your Mac.
2. Mac not seeing external drive. Go to Applications>Utilities and launch Disk Utility.
3. Click on the USB drive in the sidebar in Disk Utility.
4. Click Erase in the Disk Utility toolbar.
5. Type in a name for the formatted disk.
6. Click on the Format menu and choose either MS-DOS (FAT32) or ExFAT.
7. Click Erase.
Your USB drive will now be erased and re-formatted as either FAT32 or ExFAT, depending on the format you chose in step 6.
