Create a service in the Automator App

The first step is to start the Automator App (search it with cmd + space) and create a new document:

Now select “Service“:

In the first step in the automation process change at “Service receives selected” the “Image Files” option:

Now, on the left side, choose “Files and Folders” then “Get Specified Finder Items” and drag it to the right side:

As the same way add “Photos” -> “Scale Images” as another step in the workflow:

If you want to overwrite the original picture select “Don’t Add“. If you want to copy the original picture, select “Add” to create a copy before to resize it. I selected “Don’t Add“:

Change the desideret output resolution. I set it to 1920 px. This is a Full HD resolution:

Now save it:

And give a name like:

Test it with a single image and a lot of images

I have an image with the size of 4592 x 3056 px. It takes 6.7 MB of disk space:

Now I right click it, select “Services” and “Resize to 1920px“. This is the previously created automation service:

Automator resize it automatically in the background. You only see quickly this icon in the menu bar:

The result is a picture with the size of 1920 x 1277 px and only 626 KB of disk space:

The same can be done also for many pictures. I have a folder containing 75 pictures. The size is 404.9 MB:

Open the folder, select all pictures (cmd + a), right-click, go to “Services” and “Resize to 1920px“:

It takes about 20 seconds to resize all pictures (75). Here is the result (90% less disk space consumption!):

Congratulations! Now you should be able to resize your images

In this short tutorial I use my MacOS Sierra as client and a Ubuntu 10 as server. It will also work on other Linux / Unix versions.

Generate a key pair

The first step is to generate a key pair (private and public key) to use for authentication. The private key will remain on your computer in a safe place. The public key will be imported on the server. Open a terminal and type:

mbpl:~ lucacosta$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/lucacosta/.ssh/id_rsa): luca
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in luca.
Your public key has been saved in luca.pub.
The key fingerprint is:
SHA256:KoTUeuoGwMvHSEsEGy4KzBe09XKLQ+RVZiUbgVucS3s lucacosta@mbpl
The key's randomart image is:
+---[RSA 2048]----+
|+ .o o .+B+. |
|++ .* o.o=+ |
|*+.o.+ o+.o |
|==.o. +..o E |
|* B oo .S . |
|.= * .. |
| .o . . |
| .. . |
| .. |
+----[SHA256]-----+

Copy your public key to the server that you want connect

Replace <user>@<destination_server> with your username and destination server:

mbpl:~ lucacosta$ ssh-copy-id -f -i /Users/lucacosta/luca.pub <user>@<destination_server>
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/lucacosta/luca.pub"
xxxx@xxxxxxxxx's password: 

Number of key(s) added:        1

Move your private key in your .ssh folder

The last thing to do is to move your private key on your computer to a folder named .ssh and rename it with “id_rsa”. In my home directory I have two keys named luca and luca.pub (this is the name that you typed when creating the key pair). With the command “ls” you get the list of the files like this:

mbpl:~ lucacosta$ ls
Applications			Music
Applications (Parallels)	NoSync
Creative Cloud Files		OneDrive
Desktop				Pictures
Documents			Public
Downloads			Synology
Dropbox				luca
Library				luca.pub
Movies

Now copy your private key (in my case “luca”) to the “.ssh” folder with the new name “id_rsa”:

mbpl:~ lucacosta$ cp luca .ssh/id_rsa

Test the connection with the certificate

Now we can test the connection (if you choosed to set a password for your private key you need to enter it when prompt):

mbpl:~ lucacosta$ ssh xxxxx@xxxxxxxx
Enter passphrase for key '/Users/lucacosta/.ssh/id_rsa': 
Linux xxxxxxxxxxxxxxxxxxxxxx 2.6.32-042stab120.5 #1 SMP Tue Oct 25 22:31:12 MSK 2016 x86_64 GNU/Linux
Ubuntu 10.04.4 LTS

Solution

For those that have the same problem there is a solution: You need to open this link and click on “Get the anniversary Update now”:

It will download a setup executable. Run it:

And click on “Update Now”:

Important: For the upgrade you need at least 20 GB free disk space and Windows must be activated. Additionally I suggest to take a full backup (for example with True Image) or a Snapshot if it is virtualized.

The download is staring now:

After the installation (approximately 15-30 min depending on your pc) you will see this screen:

From now it will take another 60-90 minutes to complete the installation (the pc will restart several times):

After the installation check if windows has been upgraded succesfully typing

winver

DONE!

Only for virtualized windows: for performance optimisation don’t forget to delete the snapshot after the upgrade.

New features
