One of the aspects where Macs differ from Windows PCs the most is when it comes to installing applications. On Macs, you need mount a disk image and then unmount it and delete once the installation is finished, which can be a bit of a hassle, especially if you have to test many apps in a short amount of time.

Aug 09, 2019  Securely Delete Files Using an Encrypted Disk Image. A lot of software for the Mac is distributed in disk images or.dmg files. Disk images are also a. Can I delete.dmg files from Downloads folder? Doing so will simply free up space. Since the applications were downloaded from internet sources you can always redownload should you lose one. Drag the.dmg files to the Trashcan on the Dock or select all of them and press COMMAND-DELETE to move all of them to the Trash.

Thinking of that, this time we’ll share a couple of neat little workflows that you can implement on your Mac using Automator. With any of them, every time you are done with an app installation on your Mac, you’ll be able to eject/unmount and delete the disk image in just a couple of clicks.

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.

Delete that code and instead copy and paste the following one in the script box:

tell application 'Finder'
set selection_list to selection
if (count selection_list) < 1 then
display dialog ¬
'Please select a volume mounted from a disk image.' with title ¬
'No Selection Found' with icon stop ¬
buttons ['OK'] default button 1
return
end if
set my_selection to item 1 of selection_list
set my_kind to kind of my_selection
set my_name to name of my_selection
if my_kind is not 'Volume' then
display dialog ¬
'Please select a volume mounted from a disk image file.' with title ¬
'Selection is not a Disk Image' with icon stop ¬
buttons ['OK'] default button 1
return
end if
set volume_list to paragraphs of (do shell script 'hdiutil info | grep ^/dev/disk | grep -o '/Volumes/.*')
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
else
set my_source to POSIX file (item v of source_list) as alias
move my_source to the trash
eject my_selection
--reveal my_source
end if
end tell

Step 4: Now save this Automator service and give it a name that is easy to remember.

Step 5: Once this is done, every time you have a disk image mounted, all you have to do is select it and on the Finder menu select Services and then Eject and Delete (or whatever you named the service you just created) and the disk image file will be both unmounted and deleted with one click.

Now, let’s take a look at another Automator workflow that achieves the same objective doing exactly the opposite.

Eject DMG Files Automatically When You Drag Them To the Trash

As you can see from the title, this Automator workflow allows you to achieve the same purpose, except that in reverse, so you can avoid this message every time you drag to the trash a mounted DMG file.

Here are the steps to create it.

Step 1: Create a new document in Automator and select Folder Action from the available document types.

Step 2: At the top of the right panel, select Other… from the dropdown menu. Then, on the dialog box that pops over, type ~/.Trash to work with that folder.

Step 3: Next, on the left panel, drag the Run Shell Script action to the right panel. On the two dropdown menus that show up, select /usr/bin/python and as arguments respectively.

Step 4: Replace the placeholder script in the script box with the following one:

import string, os, sys
lines = os.popen('hdiutil info').readlines()
should_eject = False
for line in lines:
if line.startswith('image-alias'):
path = line.split(':')[1]
image_path = path.lstrip().rstrip()
if image_path in sys.argv:
should_eject = True
elif line.startswith('/dev/') and should_eject is True:
os.popen('hdiutil eject %s' % line.split()[0])
should_eject = False
elif line.startswith('###'):
should_eject = False

Once done, save the Folder Action and quit Automator. Now, whenever a DMG file is mounted, all you’ll have to do is drag it to the Trash and it will be unmounted at the same time.

Cool Tip: You can also create keyboard shortcuts for these actions by following the instructions at the end of this tutorial.

And there you go. Two different workflows to enable a very convenient feature on your Mac. Now all left to do is just choose which one you find more convenient. And the best of all? In both cases you’ll learn a bit more about Automator. Enjoy!

How to Fix Mac Folder With Question Mark

Audio Transcript

If you’ve got a lot of files and folders on your Mac, you want to clean up every once in a while to stay organized and make it easier to find specific items.

• First, locate any files or folders that you want to delete. You just click to highlight file and drag it into the handy trash can at the dock at the bottom of the screen. If you change your mind or make a mistake, you can type Command + Z at the same time to undo the last action. Select the file you’d like to get rid of and to drag it down into the trash.

• Now before you empty all the items in the trash permanently, it’s always smart to take a look at the contents of the trash bin and make sure you didn’t accidentally toss in something important. Just double click on the trash icon at the dock to open the finder window that shows the contents. If there’s something in there that you don’t want to delete, you can click on it and drag it back to a safe location. Otherwise, to empty the trash, press the Command + shift + delete at the same time or you can go up to the finder option, in the top navigation and select empty trash.

• Now you can only empty the trash when the focus in on the finder. If you’re at another application and you try to use command + shift + delete, it won’t work. You’ll get quick confirmation warning to keep you from doing something. Maybe your cat walked across the keyboard and hit Command + shift + delete. If you’re sure it’s safe to get rid of the files for good, click ok and everything in the trash will be permanently deleted.

• If you don’t want to confirm “yes” every single time you delete files from the trash, just go back to the finder menu and select preferences. Then in the preferences window, choose advanced and uncheck the box to show warning before emptying the trash. Now you won’t get that prompt any more when you empty the trash bin.
