One of the aspects where Macs differ from Windows PCs the most is when it comes to installing applications.

Let’s get started with how to set up these nice Automator workflows.
Delete DMG Files Automatically When You Eject Them
Step 1: Open Automator and choose to create a new document. From the available document types that show up on the dialog box, select Service.
Step 2: At the top of the right panel, make sure to choose from the dropdown menus the options ‘no input’ and ‘Finder’ respectively so that the end result is as the one pictured below.
Step 3: Next, on the left panel of Automator, search for the Run AppleScript action and drag it to the right panel. An AppleScript window will show up with some placeholder code in it.

end if
set my_selection to item 1 of selection_list

set source_list to paragraphs of (do shell script 'hdiutil info | grep ^image'-'alias | grep -o '/.*')
set match_found to false
repeat with v from 1 to (count volume_list)
if '/Volumes/' & my_name = item v of volume_list then
set match_found to true
exit repeat
end if
end repeat
if match_found is not equal to true then
display dialog ¬
'The selected volume does not appear to be a Disk Image.' with title ¬
'Could not find Disk Image' with icon stop ¬
buttons ['OK'] default button 1
return

if line.startswith('image-alias'):
path = line.split(':')[1]
