-[20191213] This did not work for me: I'd downloaded the Win10 ISO and followed instructions to create a boot USB stick.  The USB stick wouldn't boot. However I was able to use [[https://www.microsoft.com/en-gb/software-download/]] on a Windows machine to create a bootable USB stick. +
- +
-You have an ISO file and you want to make a bootable USB stick from it.  You will need a USB stick larger than the ISO file (e.g., ISO is 6GB, you can use a 8GB or larger USB drive.  When done, the drive is completely full.) +
-  - Run terminal <code>diskutil list</code> +
-  - Find name of the USB stick (e.g., /dev/disk4; we'll use /dev/diskX here) +
-  - <code>diskutil unmount /dev/diskX</code> or if that doesn't work do <code>diskutil unmountDisk /dev/diskX</code> you should see a message saying unmount was successful. +
-  - Now go to finder and locate the ISO file.  Right-click, and Copy <filename> as Pathname. +
-  - Back to terminal, enter part of command (don't press enter yet)<code>sudo dd bs=1m if=</code> and then paste the pathname of the ISO file to the command and then add of=/dev/rdiskX +
-  - For ISO file in smi's download directory with name silly.iso the command will look something like<code>sudo dd bs=1m if=/Users/smi/Downloads/silly.iso of=/dev/rdiskX</code> +
-  - When it completes, type <code>diskutil eject /dev/diskX</code> see ”ejected” message and unplug the USB stick. +

-====Burn an ISO file to Bootable CD/DVD==== +
-From [[https://www.online-tech-tips.com/mac-os-x/burn-an-iso-file-using-mac-os-x/]] +
- +
-  - Open Finder window, navigate to your ISO file, single-click to select it +
-  - File > Burn Disk Image +
-  - Insert disk if you haven't already; click Burn +
-//Alternatively you can right-click on the ISO file and Burn Disk Image// +
- +
-(For OS X 10.10 and earlier) From [[https://www.umass.edu/it/support/computer-classrooms/burn-a-dmg-or-iso-file-disk-macintosh|Umass link]] +
-  - Applications > Utilities > Disk Utility +
-  - Insert blank CD/DVD +
-  - Drag the *.iso file from a //Finder// window to the //Disk Utility// window, drop in left pane in the empty area below the Mac drive names. +
-  - Select the .iso file name in the left pane of //Disk Utility//, and click **Burn** (top left).   +
-  - The //Burn Disk In:// window opens and shows your CD/DVD as destination +
-  - Click **Burn** +
-  - When done the disk will eject +

-====Create an ISO file from a DVD==== +
-You have a DVD and you want to put it into an ISO file for later use. +
- +
-from [[https://superuser.com/questions/85987/mac-os-x-best-way-to-make-an-iso-from-a-cd-or-dvd]] +
- +
-===Using Terminal=== +
-For the DVD, I used /dev/disk2. I verified this with diskutil list and unmounted it first. +
- +
-<code> +
-$ sudo unmount /dev/disk2 +
-$ dd if=/dev/disk2 of=mydisk.iso +
-</code> +
- +
-Another user suggests +
-<code> +
-sudo diskutil unmount /dev/disk2 +
-dd if=/dev/disk2 of=~/myCD.iso bs=2048 conv=sync,notrunc +
-</code> +
- +
-===Using Disk Utility=== +
-Disk Utility - The on-screen prompts will guide you, but it will by default create a .dmg, which is an OS X-specific file format. Disk Utility will also create an ISO (.cdr extension) if you select the ”CD/DVD Master” option before creating the image. You can rename the extension (to .iso) after creation if desired. +

 +  * Locate these three files and rename them (like add XXX to beginning of file name -- ''preferences.plist'' to ''XXX preferences.plist'')
 +    * <ff serif>com.apple.airport.preferences.plist</ff>

 +
 +====Eject USB Stick/drive Issues====
 +If you try to eject a USB drive and get message “drive wasn't ejected because one or more programs may be using it” here's some things you can try. 
 +
 +Suppose drive is called DD1.\\ (You would run these commands in Terminal.)
 +
 +===What processes are using the drive?===
 +
 +''sudo fuser -u /Volumes/DD1''
 +
 +===Info about the process===
 +Suppose the command above returns process ID 129.\\ 
 +''ps -fp 129''\\ 
 +A process with /System/Library/ in the path is a system process.  If it's in /Applications/ then it's likely a third-party app.
 +
 +===Command that started the process===
 +''ps aux | grep 129''
 +
 +===Parent of the process===
 +''ps -o ppid= -p 129''
 +
 +===If the process is something 'mds'===
 +A process with ''mds'' in it means it's a Spotlight app.  To temporarily exclude the drive from Spotlight,\\ 
 +''sudo mdutil -i off /Volumes/DD1''\\
 +or\\ 
 +System Settings > Spotlight > Spotlight Privacy\\ 
 +Click + and select DD1, and add it to the list.
 +
 +----
 +
 +====Rename Files====
 +You have many files with similar names that you want to rename at one time.
 +
 +===Files starting with numbers===
 +You have files like “01 something” and “02 something else” etc and you want to remove the numbers in front of each of the file names; meaning you want ”something” instead of “01 something”, etc.  Here's what you do.
 +
 +  - Go into Terminal.
 +  - Go to the directory with the files: ''cd directory''
 +  - Type command: ''for file in [0-9][0-9]\ *; mv ”$file” ”${file:3}”; done''
 +The file:3 means skip the first 3 characters.
 +
 +===Files with word(s) to remove or replace===
 +Suppose you have files named like “my music song 1”, “his music orchestral 13”, “our music guitar solo” and you want to remove the word ”music” from them (so you would end up with “my song 1”, “his orchestral 13”, etc.  You use Finder for this.
 +
 +  - Open the directory holding the files in Finder.
 +  - Select the files you want to rename.
 +  - Right-click and choose ''Rename''.
 +  - In the dialog, choose ''Replace Text''
 +  - Find: put the text you want to remove or replace (e.g., ''music'')
 +  - Replace with: leave as blank to remove the text (or put the text you want to replace it with)
 +  - Click ''Rename''
 +
 +The file names will be changed.

 +You have a DVD and you want to put it into an ISO file for later use.

 +
 +===Creating ISO file Using Terminal===
 +For the DVD, I used /dev/disk2. I verified this with diskutil list and unmounted it first.
 +
 +<code>
 +$ sudo unmount /dev/disk2
 +$ dd if=/dev/disk2 of=mydisk.iso
 +</code>
 +
 +Another user suggests
 +<code>
 +sudo diskutil unmount /dev/disk2
 +dd if=/dev/disk2 of=~/myCD.iso bs=2048 conv=sync,notrunc
 +</code>
 +
 +===Creating ISO File Using Disk Utility===
 +Disk Utility - The on-screen prompts will guide you, but it will by default create a .dmg, which is an OS X-specific file format. Disk Utility will also create an ISO (.cdr extension) if you select the ”CD/DVD Master” option before creating the image. You can rename the extension (.cdr to .iso) after creation if desired.

 +You can also press Control-Command-Spacebar to open the Character Viewer.  Scroll down to find the math and other symbols, like command (⌘) and option (⌥) and a host of others.
 +
 +These symbols can be used with the standard keyboard.  Consult Webnots for what you have to do so you can use other codes that require four digit hexadecimal Unicode points (or use ^⌘spacebar).
