Press the Spotlight keyboard shortcut (by default this is Command-Space) and type the first couple of letters of an appâs name. For example, if you want to launch Safari, type SAF. One way Mac OS X differs from Windows is that when you close the last window, the app itself stays open. If you look at the Dock, you will still see a small dot underneath the app icon to indicate. Jul 02, 2014 Most Mac users know that hitting the Command+W keyboard shortcut will close the currently active window, but with a slight modification and by adding an additional key press, you can close all windows in just about any Mac OS X app or the Mac Finder.
@darksteel: Command-Q is the proper way to close an app on the Mac. Doing a killall is probably OK as well since the app is told to terminate cleanly. â tomlogic Apr 6 '11 at 0:59 2. May 22, 2020 If an app on your Mac stops responding and you canât quit the app normally, use Force Quit to close the app. Follow these steps to force quit an app on your Mac.
Your Mac is probably pretty much trouble free, at least most of the time. But occasionally you may experience a system, process, or app crash that stops you in your tracks, and prevents you from continuing to work. These crashes are usually fleeting in nature, and resolved by simply relaunching the app or restarting your Mac.
And while an occasional crash can be frustrating, itâs generally not something to worry too much about. Stuff happens, and you can think of it as one of the many reasons you have a good backup system in place. (You do, donât you?)
Now, when a crash starts occurring on a more regular basis, or you notice it always happens when x event occurs, it may be time to start delving into the crash and discover what may be causing the problem.
In this Rocket Yard Guide, weâre going to take a look at using the Console app to track down the cause of a system or app crash. With any luck, the Console app will be able to help you resolve the problem thatâs causing the crash, or at least give you a good idea of whatâs going on.
What is the Console App? (The Console app from macOS High Sierra. The sidebar shows devices reporting to the Console, as well as reports organized by category.)
Back in the early years of computing, the console was a terminal that was attached to a computer to monitor the status of the system. If you go back even further, the console may have been a bank of meters, lights, and switches that indicated how well the computer was operating.
The Console app included with the Mac is a modern-day version of the old computer console; its primary job is to help you monitor how well your Mac is operating. It can do this because of its ability to display logs, status, and error files your Macâs operating system and individual apps generate as theyâre running.
Log Files
There are a number of different types of files that apps, processes, and the system generate as they work; you can think of them as a journal or diary of whatâs going on at any point in time. While there are diagnostic files, crash files, log files, and a few other types, weâre going to refer to them collectively as log files. And for the most part, they can all be read by the Console app. Mac Command To Close An Application(OS X Yosemiteâs Console app displaying the crash log from when a system preference terminated unexpectedly. Turns out the preference pane is from an old version of an app, and is no longer supported).
The Console app can also look at process messages, and a few other real-time events, but weâre going to concentrate on looking at log files to discover what happened in the past, such as when the system or an app crashed.
Introduction to Console
Even if you havenât experienced a recent system or app crash, or an unexpected restart, go ahead and launch the Console app, so you can become familiar with the interface.
Launch Console, located at /Applications/Utilities.
Console may look a bit different, depending on the version of the Mac operating system youâre using. Most changes from system to system are cosmetic, such as a few name changes here and there, although there was a significant change going from OS X El Capitan to macOS Sierra. The primary change was the removal or relocation of some troubleshooting tools used when looking at real-time events. Since weâre not developers trying to track down bugs, that shouldnât have much effect on our use of Console to review log files.
With the Console app open, youâll see a multi-pane interface, with a sidebar used to select either real-time messages or log files for display, a toolbar across the top, and in new versions of Console, a search bar and tab bar just below the toolbar.
Accessing Log Files
Log files you may be interested in reviewing for information about what caused a crash are found in the Console sidebar under the heading: Download macos high sierra.app.
To access a log file, select the category in the sidebar youâre interested in. If the category has a chevron next to its name, expand the chevron by clicking or tapping on it.
Blackmagic Converters 7.3.4 Update â This software update adds Mac notarization support for Catalina onwards to all Blackmagic Design Mini and Micro Converters. Blue Cat Audio New. They are currently checking compatibility with Catalina. Blue Cat published The macOS Catalina Survival Guide on their blog with tips to help you with the update. Mac os catalina application compatibility list. Do not upgrade until compatibility is officially announced. While some 64-bit plug-ins may be considered compatible with macOS 10.15 Catalina, they may not be supported by the manufacturer or have problems with installation or saving. Go to the About The Mac OS Catalina 10.15 Upgrade page for more information. About The Mac OS Catalina 10.15.
A list of log files will be displayed, either within the sidebar or in the main viewing pane, depending on the Console version youâre using.
(The /var/log category contains some interesting logs, including the results of all the automatic maintenance scripts that are run in the background by your Mac.)
Select one of the listed files to view its content.
The log file names usually contain the process or app name that generated the file, the date, the name of the Mac, and finally, the file type, such as crash, diag, or analytics.
For the most part, the crash logs will be the ones youâll be interested in for troubleshooting system or app crashes, but the diag ones are also interesting to review, since they may contain information about unusual memory usage or high levels of CPU usage.
Understanding Reports
Crash reports are broken into multiple sections, with the first section containing all the information about what process crashed:
![]()
The next section tells you when the app or process crashed:
And finally, the meat of the problem: what caused the crash.
The next long section of the report lists what led to the crash in reverse chronological order, starting with the thread listed as the cause. This may seem like a goldmine for discovering what caused your crash, and it is. This section and the next, which is called a backtrace, can be very helpful for the developer to troubleshoot a system or app crash. However, itâs usually not very helpful for most users.

What Can I Do With This Information?
One of the best things you can do is contact the developer, open a support ticket, and send in this crash report. Developers need this type of information to troubleshoot and refine their apps or code. Mac Terminal Command Close Application
Depending on the version of Console youâre using, you can either:
Use the Save As command under the File menu to save a copy of the crash report, which you can then send to the developer. Or, if youâre using a later version of Console, you can use the Share button in the toolbar to attach the crash report to an email.
Mac Command Line
You can also right-click on the crash report name and select Reveal in Finder from the popup menu. You can then use the Finder to make a copy to send along to the developer.
(An app crash will display a message indicating a crash occurred. You can select the Report button to display the crash report without having to wade through the Console app to find it.)
If youâre trying to resolve the crash on your own, pay attention to the exact time the crash occurred, then check the diagnostic logs and analytics logs for unusual events that may have occurred at or near the same time. Youâre looking for excessive memory or CPU usage, as an example. You may find, for example, that WebKit, a core component of Safari, was using a great deal of RAM when the crash occurred, something you may be able to correct by adding more RAM. Or, perhaps CPU usage was so high that on a hot summer day, your Mac couldnât cope with the high temperatures.
Close All Open Apps
Another thing to look at is the app version that was crashing. Many times an app crash can be caused by an out-of-date version. Check with the app developer to see what the current version is, and which version, if any, is recommended to run on your version of the Mac OS.
For more information about using the Console app, you can find details on advanced usage at Appleâs support site for Console Help.
