To save screenshots in JPG, execute the following commands in the terminal:
defaults write com.apple.screencapture type jpg;killall SystemUIServer
macOS also support: tiff, pdf, bmp & pict.
These instructions assume you’re using the Terminal app out of the box, without ZSH or any fancy prompts like that. I trust you will be able to adapt these instructions yourself if you do.
Step 1 : Create a symlink called sublime
sudo ln -s "/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl" /usr/local/bin/sublime
Step 2 : Check that your system profile can find the symlink you just created.
open ~/.bash_profile
Step 3 : Add both these lines & then save the file :
alias subl="open -a /Applications/Sublime\ Text.app" export PATH=/usr/local/bin:$PATH
Step 4 : Reload your bash_profile :
source ~/.bash_profile
Done ! You can now navigate to any of your code/script folders in Terminal and open them in Sublime with the following commands :
subl . subl .zshrc
To disable the creation of .ds_store files, launch the Terminal application from /Applications/Utilities/ and enter the following command string exactly:

The login screen on your Mac is perfectly functional as it is, but if you want to spice it up a little bit, blogger Jacob Salmela shows you how to customize the login screen with a logo of your choosing.
If you don't want to install a whole program just for a simple tweak it's easy to do manually. All you need is a PNG that's 428 X 248. Then, you'll need to save it as four different files.
Here's instructions:
You need four copies of this file, and they need to be named:
- apple.png
- apple@2x.png
- apple_s1.png
- apple_s1@2x.png
Once they are named correctly, just drag them into the following path:
/System/Library/PrivateFrameworks/LoginUIKit.framework/Versions/A/Frameworks/LoginUICore.framework/Resources/
and then choose to replace all of them.
That's it, log out, and you should see your new logo. Head over to Salmela's site for a few sample images and instructions for making your own.
