practically everyone has files or
folders they keep on their Mac that they
don't want anyone else to access hey
guys it's max with Apple insider and
today I'll show you how to keep your
files secure by turning a folder into an
encrypted and password-protected disk
image
people are generally okay with having
various important documents stored on
their Mac using file vault to encrypt
your drives and even just having a
password to access the user account in
the first place however some users like
myself feel that some folders are just
too important or private not to have an
extra level of security especially if
you share a user account or a computer
when traveling like I am right now a
solution of this is to use Disk Utility
to create a disk image that is encrypted
and password protected open up Disk
Utility which can be found in
Applications folder under utilities
alternately use the search function and
finder to search this Mac for Disk
Utility in the disk utility menu select
file new image then image from folder a
new dialog box will appear with a number
of options available for creating a disk
image at the top you could change the
name of the disk image just something
more appropriate to its contents instead
of using the folder name by default and
where you want it to be initially saved
under encryption select either 128-bit
or 256 bit AES encryption selecting 256
bit will be more secure but will be
slower to access than the 128-bit under
the image format drop-down box select
read and write to be able to change
files held within the image once it's
created if you don't want any changes
made to the files in the folder at all
or new files to be added select
read-only now into your desired password
twice once the settings are entered
click Save then done at the location
defined in the settings you will find a
new dmg file with the name entered
during the process your new secure image
is used in a similar way to other images
to access your files the image needs to
be mounted double click the image to
mount it a dialog box will appear asking
for the password which needs to be
filled out followed by clicking ok a
tick box below the password entry offers
to save the password to keychain if
anyone else has access to the same
keychain it's probably not a good idea
once the right password is entered the
image will mount and the files will be
accessible the folder will not need the
password again when it's mounted but
will require it when it's unmounted to
unmount right-click the mounted image
and select eject after creating the
image it's tempting to delete the source
folder and its contents before doing so
make sure the image functions as planned
in
