1/ Set the view in the macOS Sierra Finder — The Finder in macOS Sierra offers four ways to view items in a window: List, Columns, Cover Flow and Icon. To choose a view, click your preferred View button at top-left of any Finder window.
In Icon view, each file or folder is represented by an icon (such as the Mac desktop). List view shows details about a file or folder, including its attributes.
Column view provides a visual trail of where you’ve been, and displays a hierarchical view of where a file is stored. Cover Flow is a modified list view that displays a thumbnail view of a file’s contents, which is great for folders of photographs, for example.
2/ Didn’t know what those buttons were? Turn on the descriptions for them. With a Finder window on the desktop, hold down the Control key on your keyboard and click in the grey area at the top of the Finder window just to the left or right of the folders file name at op centre. From the pop-out that appears, choose Icon and Text, and all your buttons get labels (it’s worth trying this in other apps like Apple Mail and Preview).
Choosing ‘Customize Toolbar’ [sic, and shown above] lets you even select which icons appear in the top area of Finder windows at all, and also get rid of any you don’t require.
3/ More view customisation — There are additional ways to customise how your items are displayed: sort items, arrange icons, and resize columns. Settings for sorting and arranging items in a folder apply until you change them. For example, if you sort your Documents folder by Date Added, the next time you view your Documents folder, it will also be sorted by Date Added.
To sort items in any view, from the View menu in Finder select Show View Options. Now click the Sort By pop-up menu and choose the sort order: Date Modified, Name etc.
In List view and Cover Flow, move the pointer over the column name you want to sort by, then click it. Click the column name again to reverse the sort order.
4/ Arrange — To arrange items in Finder windows in any view, click the Item Arrangement button, then choose an option, such as Date Created or Size.
When arranging by name, you can keep folders (in alphabetical order) at the top of the list. Choose Finder>Preferences, click Advanced, then select the “Keep folders on top when sorting by name” checkbox.
5/ Resize columns — In List view, Column view, and Cover Flow, drag the hairline divider between the column headings at the top of the window, i.e. between Name and Date Modified.
To expand a column to show all filenames in their entirety, double-click the column divider.
Control-click (hold down the Control key on your keyboard and click) any column to view all columns available. Choose a column name to display or hide it (visible columns have a checkmark next to their name).
More — You can change the text size of file names and, in some views, change the size of file icons. Open a Finder window, select the folder you want to change, then click a View button: Icon, List, Column, or Cover Flow.
Have the folder always open in this view by selecting the ‘Always open in’ checkbox to set specific preferences for specific folders. To have subfolders also open in this view, select the ‘Browse in’ checkbox.
If a subfolder opens in a different view, select the subfolder, choose View>Show View Options, then deselect the ‘Always open in’ and ‘Browse in’ checkboxes. The checkboxes must be selected for the main folder and deselected for the subfolder.
You can change the icon size, grid spacing, text size, and more by choosing the Select Icon view options.
