+## MacOS/Finder context menu entry: Convert to CD image
+
+Transforms arbitrary files and folders into an ISO 9660 joliet image
+from the MacOS Finder file/folder context menu.
+
+### How to install?
+
+1. Click on the green button "Clone or Download" -> "Download ZIP".
+2. Extract the ZIP and double-click: "Convert to CD image".
+3. Click "Install" (prompts if system service should be installed)
+
+### How to use?
+
+1. Open Finder
+2. Select an arbitrary file or folder
+3. Right-click -> "Convert to CD image"
+
+Use the .iso file of the file/folder created as ISO 9660 joliet image.
+
+### How it works
+
+The whole process is using the Automator capabilities of Mac OS.
+Automator is a scripting subsystem available since OS X 10.4 (Tiger).
+It is set up as a "Service" which takes selected files/folders of
+Finder as arguments and registeres as a context menu.
+
+The command executed (in bash) is:
+
+ handle_error() {
+ osascript -e 'tell app "System Events" to display dialog "Select a single directory (not a file) and make sure the output ISO file does not exist already."'
+ }
+
+ trap 'handle_error $LINENO' ERR
+
+ for f in "$@"
+ do
+ hdiutil makehybrid -o "$f.iso" "$f" -iso -joliet 2>> /dev/null
+ done
+
+ exit 0
+
+#### Motivation
+
+Helping PCem, an emulator to run on MacOS brought up the issue how
+to transfer files/folders from the host to the guest OS. This works
+using CD ROM image mounts but the process wasn't quite elegant and
+involved complex terminal interactions. This solution feels better.
