This is  a neat website that allows you to select the apps you want then it generates a bash script so you can download it via the command line.

I’m not a fan of the new Disk Utility in El Capitan.  I had a drive with 3 partitions and I needed to make it a single partition drive. Disk Utility would not allow me to delete one of the partitions no matter what I tried.

So I used the following Terminal command:



diskutil partitionDisk /dev/disk2 GPT JHFS+ New 0b

To break it down:

1.  diskutil - is a command line tool used for formatting disks.

2.  patitionDisk -  is an option that can be used in diskutil.

3.  /dev/disk2 -  is the location of the disk that you want to format.  You can use the diskutil “list” option  to find this information.

4.  GPT -  is the GUID Partition Table.

5.  JHFS+ - is the default filesystem type that OS X uses.

6.  New - This is the name of the partition.  You can name it whatever you like.

7.  0b - This tells the command to use all available free disk space.

For people who are not comfortable configuring their Brocade switches from the Terminal, it is possible to configure it using the GUI interface and Java on your Mac.

You need Java 7 for this to work.  I used Java 7 update 79 on OS X Yosemite and was able to configure a Brocade 6500 switch with no issues.  Java 8 will NOT work.


Step 1.  Go to System Preferences and click on the “Java” pane.  

Step 2.  Go to the “Security” tab and add an entry for your brocade switch to the exceptions list.

Step 3.  Quit System Preferences when done.

Step 4.  Launch “Terminal” and enter the command below.  

NOTE:  Change the IP address to the IP address of your Brocade Switch.

javaws http://192.168.5.10/switchExplorer_installed.html

This will launch the Java runtime environment and you will be able configure the switch from your Mac.

New in El Capitan is the ability to take screen captures of the setup assistant windows.  This is going to be very helpful when writing tutorials that involve the first boot setup assistant screens.

For each screen that you want to capture, press command > shift >3.  Upon login, all of the screenshots will be on the desktop.  

As a bonus, you can take a screen capture of the login window and it works the same way.  The next user that logs in will have the screen capture on their desktop.

The commands below will remove the settings from the Ethernet and Wi-Fi interfaces.  You can lookup more features using the man command for networksetup.  IE.. man networksetup

networksetup -setsearchdomains "Wi-Fi" "Empty"
