hey everyone this is Michael with camac
here and today I'm going to show you how
you can change the background of your
notification center in os1 Mountain line
so os10 Mountain Li obviously brought
the new notification center to Mac just
like you found on iOS and with it the
same old kind of ugly linen background
but now unlike iOS where you'd have to
jailbreak the change of Notification
Center background you can do it very
easily in M line and I'm going to show
you how to do that today so you only
need a couple things and that would be
an image and uh you know opening up a
finder window so that's first thing
you're going to do open up a finder
window and you're going to want to go to
macinach HD system Library core Services
if I can find it and then from there
there should be an application in core
Services called notification center
right here you can right click on it hit
show package content
open up contents and resources so
resources shows you all the different
files associated with notification
center so technically you could change a
lot of things about notification center
if you really wanted to skin the look of
it uh but what we're going to do today
is just skin just the background of it
which is this file right here called
linen. Tiff so this is a file that is
just exactly what you see in
notification center that's the
background and if you open it up you'll
see see that there is two versions of it
within the file there's a highres
version of it which if you look is 512 x
512 and that's for retina displays and
there's also a lower resolution version
of it which if you look is 256x 256 and
that's for normal resolution displays so
what you'll want to do is find a
background image that's preferably
repeating and or you know a plank color
would work well too uh so find an image
like that that you want to use as your
background if you want it to look the
best in notification center at its
default size and everything you want it
to either be in 256x 256 or 512 x 512
depending on what kind of display you
have Retina or non-retina now you don't
need to do this the image I'm choosing
for this demo is 400x 400 uh but it's
going to look the best if you choose one
of those sizes and the reason why it's
best to choose a repeating background is
because by default notification center
tiles the background and if you have
something that doesn't repeat or is in a
solid color if you don't really make
sure you know how the layout's going to
look it could look kind of messed up so
the first thing you're going to want to
do is back up this linen. Tiff to maybe
your desktop or something so that it's
safe and sound right there in case you
ever want to switch it back next thing
you're want to do is open up the image
you found and in this case I'm using
this really really ugly hounds tooth
image it looks really terrible which is
why I'm going to show it to you in
notification center and you'll want to
go into preview here and go to file
export because you're going to have to
export this as a tiff file and you'll
want to name it
linen and save that to your desktop so
once you have your linen. Tiff file
saved to your desktop making sure you
didn't overwrite the other one what you
want to do is drag that right into the
resources folder It'll ask you to
authenticate it and then you can select
replace once again make sure you have
your roll one backed up obviously and
enter your password hit okay and you're
all done so you can close this window
and then what you're going to have to do
is go into activity monitor so I'm going
to go into applications and then
utilities and then activity monitor and
in here you'll
find uh notification center so you just
want to search for it and here it is and
from here you can just quit the process
hit quit and nothing will happen really
but when you go over to notification
center you can see that now it
is houndtooth background now by default
notification center overlays this kind
of uh black transparent gradient to your
image I think it looks kind of nice uh
but you might not like it so it's kind
of something to be aware of before you
choose like a really dark color
background cuz you have to be aware that
whatever background you put is going to
appear darker than it does by default in
the image that's just something to be
aware of now when you're ready to change
it back to the original it's as simple
as just dragging back in the original
linen. Tiff into the resources folder
and authenticating it hitting enter and
then going back into activity monitor
and repeating the process of killing
notification center and your
notification center should be all back
to normal and you can see it looks just
fine so there you go there's how you can
change the background of notification
center very easily in OS 10 Mountain
line as always if there's anything that
you'd like to see me do a how- to on
whether it's about Mountain LI or iOS
