Serial Port Terminal is a perfect tool to ease the routine of developers' everyday work. It features everything a professional developer needs for debugging, testing and troubleshooting serial. After your second Mac/macOS install can see the disk you want to install a recovery partition onto (use either Disk Utility or diskutil list to check its presence), do this: Run this in a terminal after you have downloaded Sierra, or your OS, from the App Store.
Debugging Tools For Windows Vista
- Type tracert command and the network address/domain for which you want run this diagnostic tool. How to Perform a Traceroute on Windows 7 From the Start menu, search for Command or cmd.
- If you're using the latest version of the tool, you must be using the latest version of the Install macOS Sierra App (currently version 12.4.06). Version 4.2.5 of the patch tool and older support older versions of the installer app.
- Mac OS X has a command-line utility for performing an nslookup called 'nslookup'. An nslookup is a network utility used to resolve a name (e.g. Www.unh.edu) to an IP address (e.g. To perform an nslookup on a Mac OS X computer, you must open a Terminal window.
Wi-Fi is essential to most Mac users, but what happens when your network gets sketchy? Apple's hidden Wi-Fi Diagnostics tool should help you improve Wi-Fi performance.

The hidden tool
To access Wi-Fi Diagnostics, Option-click on the Wi-Fi icon in your Menu bar. In the drop-down menu that appears, select 'Open Wireless Diagnostics.' The Wi-Fi Diagnostics app is hidden inside /System/Library/CoreServices/Applications, from where you can drag the app icon to make it easily available in your Dock.
When you launch the app, a screen appears to tell you what the tool does and asks you to let it run tests to determine the state of your current Wi-Fi connection; these can take a few minutes to complete.
While in Wireless Diagnostics, open the Utilities Window via the Menu bar (Command-2). This shows you much information inside: Info, Logging and Performance windows; A Frame Capture mode to sniff network traffic and a Wi-Fi Scan mode that captures useful info about your own and other networks in your area.
Check the channels
The first thing to check is what channel your network is on in comparison with other networks in your area. If you find you are sharing a channel with others nearby, it helps to change the channel on your router to one the other networks aren't using -- a clear channel usually improves reception quality.
Debugging Tool For Mac Sierra Terminal
You can use the information to determine the strength of your Wi-Fi signal (or use the Performance tab in this window to see how the tool sees your network performance in the Quality section to top left).
Assessing signal strength
The Wi-Fi scan pane offers two metrics to help you determine this: Signal (RSSI, Received Signal Strength Indication) and Noise.
The first refers to the strength of the signal between your Mac and your router. Higher numbers are better but because these are rated as minus numbers, it's important to note that an RSSI of -60 is actually much better than an RSSI of -80.
Noise refers to the amount of wireless noise that may be affecting Wi-Fi reception. Neighboring networks, or the usual network interference culprits such as microwaves or some cordless phones, can impact your reception. Like RSSI this is measured in minus numbers, but a lower number is best, so a Noise level of -46 is better than one of -40.
The difference between these numbers is the quality of your network, so if you have an RSSI of -47 and a Noise level of -96 then the difference is 49. This is called the SNR (Signal to Noise Ratio) and the higher this number is the better your Wi-Fi performance will be. An SNR of 25 or above means you should have good performance.
Tips
The Performance pane shows you the quality of your Wi-Fi over time. Given that some electrical devices (including devices situated in neighboring rooms and homes) and other networks can impact your performance, you might want to keep an eye on this while moving your Mac around. You may eventually find a place in your space in which performance is better than anywhere else, or achieve better performance by switching off other computers or electrical devices.
Other terms that may be useful when using this tool:
- BSSID: This is the identifier for your airport hardware.
- Security: The kind of encryption used -- try to use WPA 2. Do not use WEP, as this is compromised.
- Transmit Rate: Data speed.
I hope this short report helps demystify and explain a little of what you can do with Wi-Fi Diagnostics.

I just upgraded to MacOS Sierra, and I realized that I can't seem to run the 'ssh -X' command in the Terminal anymore. It used to launch xterm windows, but now it's like I didn't even put the -X option anymore. It was working absolutely fine right before I updated. Other than going from OS X Yosemite to MacOS Sierra, I didn't change anything else in the setup.
EDIT:
As suggested, this is what I found in the debug logs that might be causing this problem.

I didn't need to reinstall XQuartz, but, based on Matt Widjaja's answer, I came up with a refinement.
sudo vi /etc/ssh/ssh_config
(This is ssh client config, not sshd_config)- Under the
Host *
entry add (or add where appropriate per-host)XAuthLocation /usr/X11/bin/xauth
(The location of xauth changed in Sierra)ServerAliveInterval 60
(Pings the server every 60 seconds to keep your ssh connection alive)ForwardX11Timeout 596h
(Allows untrusted X11 connections beyond the 20 minute default)
- Under the
No need to restart ssh, except, of course, existing ssh client connections. https://treetext510.weebly.com/pandora-files-recovery-tool-free-for-mac.html.
It sounds like -Y (trusted X11) would be preferable to untrusted. If you switch over to trusted, the ForwardX11Timeout line can probably be removed.
The ServerAliveInterval line is also an optional preference.
It may also be possible to make these changes in
~/.ssh/config
(the user's config file) but the permissions have to be correct.EDIT: I removed ForwardX11 and ForwardX11Trusted. They aren't needed and ForwardX11 is less secure and causes problems for git (or other tools using ssh).

I noticed macOS Sierra resetted my X11 settings so that it disabled my xAuth program. To re-enable xAuth on macOS Sierra:
- Reinstall X11/xQuartz to presumably reset any changes macOS Sierra made. I made the following changes below too although it sounds like this might be enough.
- Load up a Terminal
sudo <text editor of your choice> /etc/ssh/sshd_config
- In that file, uncomment the following lines, and set it to these values:
X11Forwarding yes
X11DisplayOffset 10
- [Update on 10/07/2017] When you reinstall X11/XQuartz, above all else, it should add an:
XAuthLocation <path_to_your_xauth>
where mine was in /opt/X11/bin/xauth. This was probably the golden step that explained why reinstalling worked.
- Restart ssh via the terminal. I did this by running:
sudo launchctl unload /System/Library/LaunchDaemons/ssh.plist
sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist

I'm having the same issues with X11 forwarding with the
-X
option after upgrading to Mac OS X Sierra.Have a look at the ssh option
-Y
(trusted X11 forwarding). While using ssh -Y <host>
things work for me. ebnerebner
Just adding the one line
XAuthLocation /usr/X11/bin/xauth
to /etc/ssh/ssh_config
works on my Mac, running MacOS Sierra, to ssh into a Linux host and be able to run X Windows programs remotely and have them display under XQuartz on my Mac.Peter EdwardsPeter Edwards
My solution to this was the following.
(1) Launch
xquartz
before trying the ssh -X
. In the xquartz options, I just enabled 'Open at login', and then it is always running in the background.(2) Go to the
xquartz
Preferences menu, and on the Security window, click the box that says 'Allow connections from clients'.After doing these things, everything works fine.

It's an old question but I recently ran into the same issue on my Mac running 10.12.6. The
DISPLAY
variable is not set in the terminal and ssh -X
doesn't work. This is what I did that solved the problem:- Reinstall XQuartz using Homebrew:
brew cask install xquartz
(the option--forced
may be necessary) - Add the XQuartz launcher to the system default (following the solution in this Reddit post:
launchctl load -w /Library/LaunchAgents/org.macosforge.xquartz.startx.plist
- Restart the system.
After doing these, my
DISPLAY
variable is set properly:$ echo $DISPLAY/private/tmp/com.apple.launchd.mfXFpzZ0gC/org.macosforge.xquartz:0

And X11 forwarding in ssh works as well.

Just upgraded my macbook from El Capitan to Sierra. Simply reinstalling Xquartz has done the trick for me, using ssh -X [linux server]

I spent the whole day looking for solution only to realize that the recent Sierra does not ship with XQuartz installed https://support.apple.com/en-gb/HT201341. Upon install (https://www.xquartz.org/) all works.
user8552682user8552682
If Quartz is installed, all that is needed is to add the line 'X11Trusted yes' under 'Host *' in the /etc/ssh/ssh_config file.
