Not interested in attracting mosquitoes? Keen to save battery and power? Find out here how to quickly turn off the screen on a Mac at any time using the mouse or the keyboard.
Inspired by Apple's Automator application, Fake looks like a combination of Safari and Automator that allows you to run (and re-run) 'fake' interactions with the web. Power Users will love Fake for automating tedious web tasks like filling out lengthy forms and capturing screenshots. Preview is the vendor-supplied image viewer and PDF viewer of the macOS operating system. In addition to viewing and printing digital images and Portable Document Format (PDF) files, it can also edit these media types. You can use Apple's built-in app Automator or third-party macro recorders. First, let's learn about Mac's Automator. You can use it to record various workflows like workflow in the print dialogue, set quick actions in Finder windows, Touch Bar, or when calendar events occur, and beyond. Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen.

of the known earth had an important function in Ancient Egypt: Nut swallowed the sun at night to end the day and, in the morning, gave birth to it so a new day could begin.
Now, how about having your Mac screen's bright light swallowed at will and any time (without putting the whole computer to sleep)?

How to Turn Off the Screen on a Mac: FAQ
How can I make sure my Mac does not go to sleep with the display off?
Of the countless ways to keep a Mac awake, one is particularly easy and typically at hand:
- Open Music on Mac (or iTunes).
- Pick a random song.
Tip: I'm partial to Telemann, Paul Desmond, and Silvius Weiss; and a few precious birds' songs, of course. - Play it on repeat.
Be safe: Do not play a radio station; iTunes may automatically stop playback after some 2 hours or when it runs out of things to play deemed interesting enough.
Tip: You can set up a keyboard shortcut for looping one song.

Preview is the vendor-supplied image viewer and PDF viewer of the macOS operating system. In addition to viewing and printing digital images and Portable Document Format (PDF) files, it can also edit these media types. It employs the Aqua graphical user interface, the Quartz graphics layer, and the ImageIO and Core Image frameworks.
History[edit]
Like macOS, Preview originated in the NeXTSTEP operating system by NeXT,[1][2] where it was part of every release since 1989.
Supported file types[edit]
Preview can open the following file types:
- AI – Adobe Illustrator Artwork files (if PDF content included in file)
- BMP – Windows Bitmap files
- CR2 – RAW Image file used by Canon Cameras
- DAE – Collada 3D files
- DNG – Digital Negative files
- EPS – Encapsulated PostScript files (after an automatic conversion to PDF)
- FAX – faxes
- FPX – FlashPix files
- GIF – Graphics Interchange Format files
- HDR – High Dynamic Range Image files
- ICNS – Apple Icon Image files
- ICO – Windows icon files
- JPEG – Joint Photographic Experts Group files
- JPEG 2000 – JPEG 2000 files
- OBJ – Wavefront 3D file
- OpenEXR – OpenEXR files
- PDF – Portable Document Format version 1.5 + some additional features
- PICT – QuickDraw image files
- PNG – Portable Network Graphics files
- PPM – Netpbm Color Image files
- PNTG – MacPaint Bitmap Graphic files
- PPT – PowerPoint files
- PS – Adobe PostScript files (after an automatic conversion to PDF)
- PSD – Adobe Photoshop files
- QTIF – QuickTime image files
- RAD – Radiance 3D Scene Description files
- RAW – Raw image files

The version of Preview included with OS X 10.3 (Panther) could play animated GIF images, for which an optional button could be added to the toolbar. As of OS X 10.4 (Tiger), Preview lost playback functionality and animated GIF files are display as individual frames in a numbered sequence.[3][4]
Features[edit]
Editing PDF documents[edit]
Preview can encrypt PDF documents, and restrict their use; for example, it is possible to save an encrypted PDF so that a password is required to copy data from the document, or to print it. However, encrypted PDFs cannot be edited further, so the original author should always keep an unencrypted version.
Some features which are otherwise only available in professional PDF editing software are provided by Preview: It is possible to extract single pages out of multi-page documents (e.g. PDF files), sort pages, and drag & drop single or multiple pages between several opened multi-page documents, or into other applications, such as attaching to an opened email message.
Editing images[edit]
Preview offers basic image correction tools using Core Image processing technology implemented in macOS, and other features like shape extraction, color extraction, cropping, and rotation tools. When annotating images, Preview uses vector shapes and text until the image is rasterized to JPEG, PNG or another bitmap format. PDF and image documents can also be supplied with keywords, and are then automatically indexed using macOS's system-wide Spotlight search engine.
Import and export[edit]
Automator Mac App
Preview can directly access image scanners supported by macOS and import images from the scanner. Preview can convert between image formats; it can export to BMP, JP2, JPEG, PDF, PICT, PNG, SGI, TGA, and TIFF. Using macOS's print engine (based on CUPS) it is also possible to 'print into' a Postscript file, a PDF-X file or directly save the file in iPhoto, for example scanned photos.
Beginning with Mac OS X 10.7 Lion, Preview restricts the Format option popup menu in the Save As dialog to commonly used types. It is possible to access the full format list by holding down the Option key when clicking the Format popup menu.[5] (GIF, ICNS, JPEG, JPEG-2000, Microsoft BMP, Microsoft Icon, OpenEXR, PDF, Photoshop, PNG, SGI, TGA, TIFF)
New features in Version 7[edit]
A new 'edit button' where the picture can be edited is introduced in Version 7. The 'edit button' allows options to insert shapes, lines, do cropping, and among other things.
