A huge chunk of the fun that you’ll find on the web is the ability to download images and other files to your MacBook. If you’ve visited a site that offers files for downloading, typically you just click the Download button or the download file link, and Safari takes care of the rest.
Jan 19, 2018 Most.pkg files will do all the work for you, but sometimes with.dmg files, you will need to drag the app to the applications folder. Your application is now installed. Apple and app developers use core services to enhance an application's capabilities. For example, Mac Mail uses the Archive Utility to compress and decompress attachments, while Safari uses it to decompress files you download. Most users never need the modify the settings for the Archive Utility. Try the utility as configured in its default state. You can modifying what Safari considers a 'safe' file using a local file that will override the global file-type security assessments. If there's a file named com.apple.DownloadAssessment.plist in.
While the file is downloading, feel free to continue browsing or even download additional files; the Downloads status list helps you keep track of what’s going on and when everything will be finished transferring. To display the Download status list from the keyboard, press cmd+Option+L. You can also click the Download button at the upper-right corner of the window to display the Download list.
By default, Safari saves any downloaded files to the Downloads folder that appears in your Dock. To change the specified location where downloaded files are stored — for example, if you’d like to save them directly to the desktop or scan them automatically with an antivirus application — follow these steps:

To download a specific image that appears on a web page, move your pointer over the image, right-click, and choose Save Image As from the pop-up menu that appears. Safari prompts you for the location where you want to store the file.
You can choose to automatically open files that Safari considers safe — things such as movies, text files, and PDF files that are unlikely to store a virus or a damaging macro. By default, the Open “Safe” Files after Downloading check box is selected. If you’re interested in preventing anything you download from running until you’ve manually checked it with your antivirus application, you can deselect the check box.
Luckily, Safari has matured to the point where it can seamlessly handle most multimedia file types that it encounters. However, if you’ve downloaded a multimedia file and Safari doesn’t seem to be able to play or display it, try loading the file in QuickTime Player. QuickTime Player can recognize a huge number of audio, video, and image formats. (Also, consider the freeware Perian QuickTime plug-in.)
A Mac App I've been working on downloads files to ~/Library/Application Support/<app>/. These can be opened and saved, and are removed after a specified amount of time.
However, with Sierra, all files in the Application Support folder don't seem to be modifiable. Each time we try and save, the message 'The original document can't be changed, so a duplicate with your changes has been created'. Since the App needs the files to persist, this breaks the App totally.
I've noticed actually copying and pasting files into the Application Support folder provides the file with the same limitation. If we paste to ~/Library/ it's fine, the files can be saved directly on modification, but if we paste to ~/Library/Application Support, the file is unwritable.
Even if, after we paste in a file, in Terminal we run:

And then clarify that the permissions are '-rwxrwxrwx', it's still unwritable.
