The Mac port has a number of layout tests that are skipped because they timeout. The timeout is caused by the context menu not being dismissed during the test. Some tests attempt to dismiss the context menu by trying to process an escape character, but this doesn't seem to reliably trigger the menu to be dismissed. A quick review of mac-wk2 TestExpectations shows several tests suffering from this problem: editing/selection/5354455-1.html editing/selection/5354455-2.html editing/selection/button-right-click.html editing/selection/context-menu-on-text.html editing/selection/context-menu-text-selection-lookup.html editing/selection/context-menu-text-selection.html editing/selection/empty-cell-right-click.html editing/spelling/context-menu-suggestions-multiword-selection.html editing/spelling/context-menu-suggestions-subword-selection.html editing/spelling/context-menu-suggestions.html editing/spelling/spellcheck-input-search-crash.html fast/events/context-no-deselect.html fast/events/context-nodrag.html fast/events/context-onmousedown-event.html fast/events/contextmenu-scrolled-page-with-frame.html fast/events/right-click-focus.html fast/events/selectstart-prevent-selection-on-right-click.html media/controls-right-click-on-timebar.html

Once this patch is landed I will reactivate the failing tests.
Committed r186694: <http://trac.webkit.org/changeset/186694>
It looks like editing/selection/5354455-{1,2}.html still fail due to poor Win/Unix emulation on Mac. I'll leave these skipped.
Two more failures: editing/spelling/context-menu-suggestions-multiword-selection.html editing/spelling/context-menu-suggestions-subword-selection.html These seem to time out due to spelling support problems.
Two last failures: fast/events/right-click-focus.html: This fails because Mac doesn't seem to shift focus when context menu is being driven in DRT/WKTR. fast/events/context-onmousedown-event.html: An actual mouse-down event isn't being emitted by DRT/WKTR.
Unskipped tests in r186699.
