Screen Capture Mac Os Big Sur

admin

You may already know how to take screen or a portion of the screen in Mac OS X. You can press ⌘,Shift,3 keys to capture the entire screen or ⌘,Shift,4 to capture a rectangular portion of the screen. By default the screenshots will be stored as .png files. But you can easily change the default settings anytime and can save the screenshots as .jpg, .pdf, .gif or .tiff file format. Here, first we have changed the default settings to save the screenshots as .pdf files later we have changed it to .jpg.

MacOS Big Sur elevates the most advanced desktop operating system in the world to a new level of power and beauty. Experience Mac to the fullest with a refined new design. Enjoy the biggest Safari update ever. Discover new features for Maps and Messages. Record the entire screen Click in the onscreen controls. Your pointer changes to a camera. Click any screen to start recording that screen, or click Record in the onscreen controls. Prior to Big Sur, one could change the macOS window screenshot default to hide shadows by setting defaults write com.apple.screencapture -bool disable-shadow. That no longer seems to work. Holding ⌥ while taking a window screenshot in Big Sur still hides the shadow, so it appears the capability is still present.

As per your requirements you may change the default format anytime:

.jpg/.png: Suitable for web uploads or for using in blog posts.
.gif: Because of the lowest size on disk, it’s suitable as resources of .css files (as it can reduce the loading time of a website).
.tiff: Suitable for Printing.
.pdf: Suitable when you are capturing Web pages, rich-documents, Capturing applications like Numbers, Pages.

Steps capture screenshot as PDF or JPEG in Mac OS X

1. Open Terminal: While you are in Finder press Shift,⌘,A to open Applications and then click on Terminal. You can also open Launchpad and search for Terminal.

2. Now in terminal run below commands to change the screen-capture format to .pdf.

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

Now take screenshot by pressing ⌘,Shift,3 or ⌘,Shift,4, you will find that the screenshot has been saved as a .pdf file.

run below commands to change the screen-capture format to JPEG.
defaults write com.apple.screencapture type jpg;
killall SystemUIServer;

The process is same for .gif, .tiff or to revert back to default .png. That’s it.

It is always a bit of fraught process upgrading a computer OS, especially for a development machine with loads of tools and libraries installed. So I try to do it as infrequently as I can get away with. On Windows I generally buy a new PC rather than upgrade OS. However glitches had been reported in Easy Data Transform on macOS 11.0 (Big Sur) and I wasn’t ready to abandon my 2017 iMac, so I decided to bite the bullet and upgrade it from macOS 10.13 to 11.0.

The initial upgrade of OS was straightforward enough. But when I tried to run Qt Creator the CPU shot to 99% and stayed there, making the machine unusable. A glance at Activity Monitor showed that several XCode related processes were going crazy. After a bit a Googling I managed to find this magic incantation to type into the terminal on a forum post:

I was then able to rebuild my Qt-based products: Easy Data Transform, PerfectTablePlan and Hyper Plan using the existing installs of Qt 5.13.1 and Qt Creator 4.8.0.

I had to update some of the software I use:

  • DropDMG
  • Beyond Compare
  • SnagIt

Annoyingly, I had to buy an upgrade of SnagIt as the 2018 version doesn’t work on Big Sur. Even more annoyingly the upgrade costs nearly as much as a new licence, which feels predatory.

The Subversion command line no longer worked from the terminal, but that was easily fixed by adding /Applications/XCode.app/Developer/usr/bin to PATH in my .profile.

So far I haven’t been able to get the following to work:

  • XCode
  • Hammer4Mac

XCode 10.1 falls over if I try to start it. It says that it requires additional components and then fails to install them. I may upgrade XCode at some point. But I only use the compiler from the command line via QtCreator, so it doesn’t really matter at present.

Hammer4Mac is a static website builder I use to build the PerfectTablePlan website and a couple of other mini sites. I upgraded to the latest version. It starts, but returns ‘Build failed’ for all 3 websites. No clue as to why. I Tweeted the creator, but got no reply. It appears to be abandonware. If so they should really take down the Hammer4Mac website. I guess I will use it from my macOS 10.14 laptop and then eventually do the tedious job of porting those websites to Jekyll.

Hopefully I won’t have to do another major upgrade of macOS any time soon (I may buy a new Mac next time).
