From the Apple Support database article regarding network connection priority:
If you connect to the Internet or a network in several different ways
(using Wi-Fi or Ethernet, for example), you can change the order of
the network port configurations your computer tries when connecting to
the Internet or network.
If there are multiple active ...
It's in your Network Preferences. Here's screen shots from 10.7.3.
Access the settings from the gear at the bottom of the network type sidebar.
Choose "Set Service Order..." to drag them into the preferred order.
The answer to your question as asked in the title is it really depends on what ports you have available, personal preference, cost, etc.
I say this because both USB 3.0 and Thunderbolt are faster than ethernet, so it doesn't matter which way you go from a speed point of view.
More specifically (and at the risk of oversimplifying it):
According to Apple Support:
Choose Apple menu > System Preferences, then click Network.
Click the Action pop-up menu , then choose Set Service Order.
Drag a service, such as Ethernet, to the top of the list.
Click OK, then click Apply to make the new settings active.
Full article is here.
It's possible to set network access interface priority order. Go to System Preferences → Network, click on the lock icon to unlock the preference pane. Now click on the gear icon shown towards the bottom of the network interface list, and select Set Service Order... command.
Now, in the new pane that opens, you can drag the priority network interface (...
I recommand you to never use a configuration where you may have at the same
time different interfaces up on the same machine. You won't have any easy knowledge and control of this dual connectivity.
This may lead to huge difficulties to analyse even the simplest network trouble.
This may also cause loops within company or personnal networks very hard to ...
We have a brand new Late 2016 Macbook Pro and 2 Apple/LG 21.5 USB-C 4K monitors. Daisy-chaining/MST does not work. We are using the monitors and nothing else with the original cables.
Only way to get it to work is to connect each to individual USB-C ports on the MBP.
Sad but true.
First of all, connect the adapter and reboot. In many cases, it will solve the problem. You need to reboot because the adapter is not hot-pluggable. For the same reason, if you remove and re-insert the adapter, it won't work until you reboot.
If you still have difficulties, I've found driver information while looking at the Thunderbolt to Gigabit Ethernet ...
The solution is to try and reset as many network related system preferences as possible. To be more specific:
Unplug the Thunderbolt Ethernet adapter.
Create and Apply a new default network location (system preferences).
Remove all older pre-existing network locations.
Remove the following preference files (global and user specific found in /Library/...
When your connections starts timing out, can you do arp -an in Terminal.app and see if you still have all MAC addresses in the ARP table? as in - your router's MAC address, or the host you're trying to ping?
If you do (and you have the time before it starts working again), can you flush the arp table (sudo arp -ad) and then see if your router's MAC address ...
Late to answer but still for those landing here looking for a Ethernet connectivity status icon in menu bar, check this macOS app Ethernet Status - The Missing LAN Status Bar Icon. It shows ethernet interface, IP Address and if interface is active via changing menu bar icon. More here
It does differentiate between WIFI and Wired Ethernet and shows the ...
There may be several different ways to accomplish what you're asking, however, I'll just throw this out there.
I have a MacBook Pro that doesn't have a built-in Ethernet Port so in my examples I'll use Hardware Port: Wi-Fi since I tested this in both examples below and it worked, however you can change it to Hardware Port: Ethernet if that is what the ...
I just installed menumeters.
If you go into the preferences for MenuMeters it is possible to add a network icon to the OSX menu bar.
Clicking on the icon, indicates the current network (i.e., wifi or Ethernet).
This is a reasonable solution, but it still requires you to click on the icon to see whether ethernet is connected.
Here is a step-by-step guide for you:
Temporarily disable any Firewall/Internet Security solution/packet filter on your Mac (like LittleSnitch/Hands Off!/Kaspersky Internet Security etc.)
Connect to the administrative interface of your router with a working Mac.
Make a note of the internal interface (probably 192.168.0.1 in your case)
If your router uses ...
Try System Preferences > Profiles. It listed my 802.1X profiles and I was able to remove them from there.
Alternatively, you can manually edit configuration files in /Library/Preferences/SystemConfiguration (see this post) - grep the files located there for the name of your profile.
(Using OS X Mavericks)
(Profiles is located in the second row from ...
As far as I understand, you can run a lot of generic ones that don't have Apple-signed drivers by disabling "System Integrity Protection" (SIP)
Steps to get your adapter working if you've never used the adapter before in Mac OS 10.11 El ...
An answer from my personal experience: I've used both
original Apple's Thunderbolt to Gigabit Ethernet adapter
Cable Matters DB50 USB 3.0 to Gigabit Ethernet adapter
and noticed no difference when testing for speed nor in daily use.
I would recommend Thunderbolt, as it is essentially external PCI-Express, which is the same bus an internal network card (among other things like graphics cards, etc) is attached to.
PCI-E (and thus Thunderbolt) support DMA, which allows the network card to write packets to the system's memory directly without involving the CPU. USB as far as I know does ...
I had this problem, too, and an Apple Support call and Genius Bar visit later, I had the answer: if you're using Network Locations that preexist your Thunderbolt display, it doesn't seem to auto-add the possibility of "Display Ethernet" to your available network ports. To solve this, either:
Create a new Location in your Network system preferences. It will ...
From Super User: If I have two internet connections on osx, how can I use both to increase my bandwidth?:
Short answer: no. With 2 links, you have 2 IP addresses. It can be done with some specific higher end NICs (e.g. Intel quad cards), but they will appear to the rest of the network as a single IP address in that mode. If the assumption is that you have ...
I fixed this issue by installing my adapter's chipset driver on Mac Os X.
After rebooting, the usual command (e.g. sudo ifconfig en6 ether xx:xx:xx:xx:xx:xx) works as expected.
Below the details.
I had the same problem with a Tecknet UL688G USB 3.0 to 10/100/1000 Gigabit Ethernet adaptor.
On both Mac Os X 10.10.5 (Yosemite) and 10.11.4 (El Capitan) the ...
After inspecting your configuration, it seems two factors might be in play here:
A quick way to confirm a working internet connection but bad DNS is going to a website by using it's IP address rather than it's domain name. For example: http://188.8.131.52 which is a WikiMedia Foundation address. It should say something like "unconfigured ...
I'm not sure if this answers the question but I'm testing this out right now with a new MacBook Pro Touchbar 13" with 4 USB-C ports.
In the testing I'm using the Minix Neo C Hub which has
2x USB3 - Type A ports
SD Card Reader
Another USB-C that you can use for your power adapter
I'm able to get two monitors working, one through HDMI ...
In a default setup, macOS will prefer the ethernet connection over the WiFi connection automatically. You do not need to fear that you're limiting your network speeds by also connecting to WiFi.
You can change the default order by opening System Preferences, select Network, click on the Gear icon below the interface list and select "Set Service Order". ...
The MAC Address is unique and a property of the actual network hardware (although it can be spoofed). So your adapter has its own MAC address, as does the the network interface in a Thunderbolt display, and the Wi-Fi in your MacBook Air.
Different Thunderbolt to Ethernet adapters will have different MAC addresses, but moving one between different ports won'...
After doing a little research on Dell's daisy chaining monitors, I came across this bit of info on their support site:
Multi-Stream Transport (MST), also known as Daisy Chaining, is a new
connection specification that allows multiple monitors to be connected
in series with the video signal being passed from the computer to a
monitor, and then from ...
If you are using VMWare or Parallels you can connect a virtual machine directly to one specific network interface (WiFi in the example)
and use the other interface as the default for OS X:
In the specific situation described in the question it may be too much of a hassle though.
