Set Custom Message in Log in Screen

Set Custom Message in Log in Screen

Mac requires a password at several times just like Linux. Although, you can allow automatic log in, which won’t ask any password at startup but if you want to make your Mac secure, this is recommended to disable automatic log in. When you disable automatic log in, you will start getting a log in screen just like Windows and other OS during startup, where you will have to enter your password.

However, you can show custom messages on your log in screen that may be helpful if you have forgotten your MacBook at any public place and someone is trying to log in to your Mac. He/She can easily check your custom message and you will get your Mac back if you have a good luck. To set a custom message in your Mac’s log in screen, just follow the following steps:

Go to System Preferences >> Security & Privacy >> Unlock to Make Change >> Tick on “Show a message when the screen is locked” >> Set Lock Message >> Write down your message

Disable Drop Shadow in Screenshot

Alike Windows, Mac comes with an in-built screen capture tool. You can simply press cmd + shift + 3 or cmd + shift +4 to capture your screen. However, if you have checked your captured screenshots minutely, you might have already seen the huge drop shadow around the screenshot. This default setting/customization might be annoying at some moments.

Nevertheless, don’t worry. You can easily disable this drop shadow within seconds. To do so, just open your Terminal and enter the following command:

defaults write com.apple.screencapture disable-shadow -bool true

Now, you have to restart your Mac to get the change.

Save any Screenshot as PDF

Suppose, you have to send some screenshots to someone in PDF. Generally, most of the Mac users use many Image to PDF converter to convert captured images into PDF file. But, do you know that you can do this conversion without installing any third-party software? To do so, open your Terminal and enter the following command:

defaults write com.apple.screencapture type pdf;killall SystemUIServer

Now, you may have to restart your PC.

Show Hidden Files and Folders

By default, you won’t get any system created files (.DS_Store) or any other self-made hidden files in your Mac. Sometime, we need to show hidden files to do something important. For example, you have hidden some files from your Windows and wanted to use that in your Mac. At such moment, you can simply use this following Terminal command:

defaults write com.apple.finder AppleShowAllFiles YES; killall Dock

Set Any Image as Folder Icon

This is one of the best tricks you can do. Although, Windows does not allow users to do so without having any third-party software but you can set any image as folder icon without installing any software in your Mac. To set any image as folder icon, just right-click on any folder and select Get Info. Then drag and drop the image on the default folder icon that is situated at top left.

How to merge two or more columns in OSX Numbers

There will be occasions where you will want to merge two columns in numbers. Like

  • Merging two columns with base url and image name to get the full image path.
  • Combining first name and last name columns to get the full name.

There can be several other cases. Recently I exported list of emails which had separate columns for first and last names. But my newsletter software wanted them as name,email. So I had to merge the first and last name columns with a space in between them.

Here is my list, which has 3 columns, first name, last name, and email.

Merging columns in MAC Numbers

I want to merge first name and last name into one. Here are the step by step instructions to do it

  1. First create a new column, say D.
  2. Select an empty cell in it and click the fx(formula) button in the menu.

  3. Then enter the formula (It should look like the screenshot below) and hit enter.
  4. Tadaa!!, One row is merged. Now to merge all rows, copy the contents of this cell (cmd+c) and
    and select entire row D and paste(cmd+v)

    Copy the selected cell (cmd+c) and the select entire column by clicking on the column letter and press cmd+v
    Copy the selected cell (cmd+c) and the select entire column by clicking on the column letter and press cmd+v

Now we have the column we want but, what if we don not want the original columns?

You may think that you can simply delete them, but you can not, as our new column D is dependent on A and B. If you make any changes to A and B they will be reflected in D to.

So, export the sheet as CSV, and open this file and now you will be free to delete the source columns in this new file as the columns have no link to others.
