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:
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 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.

Get the best performance from your USB devices
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.

There are several ways to update your JunOS software but one of the common and safe method is doing through the CLI and a USB memory stick.
First, get your software from Juniper.net first and save it to a MSDOS formatted USB stick.
Then, follow those steps (as root, through serial console is highly recommended) :
1. Connect the USB stick to your Juniper device (you should have an output on the console after connecting the device letting you know the device name). Note that you need to be into the Unix shell to perform the following step, the prompt will be displayed as ” % “.
Try to locate your device and his volume doing the following command :
(in this example the device and volume will be “da1” and “da1s1“)
2. Mount your USB drive using the following commands :
Install Mac Os From Usb
request system software addjinstall-Your-Package-Name.tgzno-validate no-copy |
5. You will now receive a message once the installation will be completed. Then you need to reboot your device to load the new software :
NOTE : If the software update failed, the device should boot to the rescue image on your previous JunOS version. If this is happening, probably your jPackage was corrupted. Download again and make sure you copy the image on the flash instead of executing the installation directly from your USB stick.
