OS X "arrange by" in column view

I usually have the OS X Finder set to display folders and files in alphabetical order by setting the view mode to arrange the display of files and folder by name. But sometimes I switch to view by size, etc. However, when I then switch back to view the files and folders in column mode arranged by name, Finder doesn't actually display them in alphabetical order, which is annoying.

I finally got to the point where the issue was so annoying that I felt I had to find a solution. I found Brett Taylor's HOWTO: Fix file sorting in Finder‘s column view on Mac OS X Lion article which provided a means to address the issue. Though the title for his article, which acknowledges Barney-15E's post at In OS X Lion, Finder will not "Arrange By > Name" in "Column view", references OS X Lion, I found the solution worked for OS X El Capitan (10.11.6) on my MacBook Pro.

Losing Internet connectivity via Wi-Fi on an OS X system

On my MacBook Pro laptop running OS X El Capitan (10.11.6), I've been losing Internet connectivity periodically. Though it appears I still have Wi-Fi connectivity, when I attempt to access websites through a browser I find that I can't access sites at times, though a moment before I had no issues browsing the Web. Firefox will display a "Server not found" message. If I go to a Terminal window and try to ping any IP address, I see "request timeout" messages.

$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
^C
--- 8.8.8.8 ping statistics ---
3 packets transmitted, 0 packets received, 100.0% packet loss

If I check the status of the WiFi connection using the airport command, I see that it is very noisy, though the signal stength is good, which I would expect, since the laptop is only a few feet from the wireless router.

$ /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I

Installing MySQL on OS X El Capitan

The steps below can be taken to install the MySQL relational database management system software on an Apple OS X/macOS system. The steps were taken for MySQL version 5.7.17 on a MacBook Pro laptop running OS X El Capitan, but should be similar, if not exactly the same for other versions of MySQL and on other versions of OS X.

Using Python scripts with Apache on OS X El Capitan

If you've got the Apache web server software working under OS X El Capitan, but want to use Python scripts with Apache, the following steps will allow you to run Python scripts from a cgi-bin directory.

First, ensure that the hash sign (#) is removed from the LoadModule cgi_module libexec/apache2/mod_cgi.so in /etc/apache2/httpd.conf. If you need to remove the hash/pound sign, restart Apache after modifying the file, which you can do with sudo apachectl restart. You will also need to use the sudo command to edit the file, if you edit it with a text editor such as GNU nano or vi.

Using Perl with Apache under OS X El Capitan

If you've got Apache running on your Mac OS X system and want to be able to display the output of Perl programs, you need to remove the hash sign (#) from the following line in /etc/apache2/httpd.conf.

#LoadModule cgi_module libexec/apache2/mod_cgi.so

You will neeed to edit the file with a text editor, such as the TextEdit app found in the Applications directory, or GNU nano or vi. And you will need to run the editor with root, i.e., administrator privileges by using the sudo command in order to be able to save modifications to the file. E.g.:

sudo nano /etc/apache2/httpd.conf

PHP for Apache on OS X El Capitan

If you are running an Apache web server under OS X El Capitan and want to use PHP with Apache, you will need to take some additional steps after you've got Apache running on OS X/macOS. Once you've got Apache working on the system, you can create a .php file, e.g. phptest.php and have the page displayed by your browser if you visit the page, but PHP code within the page won't be executed. E.g., suppose the phptest.php page contains the following code:

<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>PHP Test</title>
</head>

<body>

<h2>A test page</h2>

<?php phpinfo(); ?>

</body>
</html>

If I visit the page using a browser, the HyperText Markup Language (HTML) code on the page will be displayed, e.g. the "A test page" heading will be displayed, but the information that the phpinfo() command would display regarding the PHP settings for a system on which PHP is working won't be displayed. You could also try a simple PHP echo command, e.g. <?php echo "This is the output from a PHP echo command."; ?>, but the output from that command would not be displayed, either.

Running an Apache web server under OS X El Capitan

Apple's OS X/macOS operating system (OS) comes with the Apache webserver software, which I decided to enable on my MacBook Pro laptop running OS X El Capitan, version 10.11.6 on the laptop.

The Apache web server software isn't running by default and you can no longer enable it through the Sharing option under System Preferences as in some earlier versions of OS X, but you can start it from a command line interface (CLI) by opening a Terminal window (Terminal is found in the Applications/Utilities folder), with the command sudo apachectl start. Once you start the software, you will see the system is listening on the well-known port for Hypertext Transfer Protocol (HTTP) connections, port 80, by using the netstat command.

$ sudo apachectl start
Password:
$ netstat -a | grep http | grep LISTEN
tcp46      0      0  *.http                 *.*                    LISTEN

You can't open the application "Firefox.app" because it is not responding

I killed Firefox on my MacBook Pro laptop running OS X Yosemite (10.10.5) by clicking on the Apple icon at the upper, left-hand corner of the screen then selecting Force Quit and then selecting Firefox and clicking on the Force Click button. But when I tried to reopen Firefox, I saw the message 'You can't open the application "Firefox.app" because it is not responding.'

I clicked on OK and used Force Quit Applications again. I saw Firefox in the list and again forced it to quit. I then clicked on the Firefox icon in the Dock at the bottom of the screen again, but Firefox didn't appear to open. I double-clicked on it again, but it still didn't appear to open, though it appeared in the Force Quit Applications list again with "not responding" appearing next to its entry in the list of open apps. I tried clicking on the Firefox icon in the Dock a third time and this time saw the 'You can't open the application "Firefox.app" because it is not responding' message again, though reopening Force Quit Applications again did not show "not responding" next to the Firefox entry in its list. Nor was any other application listed as being unresponsive. I tried the Force Quit step again. Firefox remained in the list until I closed and reopened Force Quit Applications. Though Firefox wasn't in the Force Quit Applications list, I did see a process associated with Firefox when I used the ps command to view processes running on the system.

$ ps -ef | grep -i Firefox | grep -v grep

Locating an OS X window that is no longer visible

I started the installation of a program on a MacBook Pro laptop running OS X Yosemite (10.10.5), but then switched to a Terminal window. When I wanted to switch back to the installation window I could no longer find it in the OS X dock at the bottom of the screen, nor could I see it by cycling through open windows with the Command-Tab keys, nor did I see it when I clicked on the Apple icon at the upper, left-hand corner of the screen and looked for it under Force Quit. When I tried to restart the installation by clicking on the Apple Disk Image .dmg file, nothing appeared to happen. I was able to find the invisible window by hitting the F3 function key on the keyboard, though. I could then see the hidden DiskImages UI Agent window that I hadn't been able to locate previously. I was able to click on it and bring it to the foreground where I could proceed with the installation.
