Nov 26, 2013 App Store Preview for Mac provides a snapshot of the App Store right from your OS X Dashboard. An easy-to-use widget, it lets you sort and search for apps based on cost and popularity. Nov 18, 2013 Users who are comfortable with the command line can use a better solution, which utilizes the ping tool to detect an active internet connection and the text-to-speech say command to verbally announce when things are live again. Be sure to have the volume turned up on the Mac.

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.

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]

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.

Issues[edit]

As of OS X 10.9.2, Preview does not support ISO-standardized PDF (ISO 32000), and when saving, destroys aspects of PDF files without warning to the user.^[6]
