How to re-enable missing Disclosure arrows? OS: Sierra (10.12.6)
I view my folders as List in Finder, but in a recent attempt to refresh my app icon file, I somehow messed up my View settings. From what I've gathered online, I had to set &quot;Arrange by&quot; to &quot;None&quot; (Cmd+Option+0) and &quot;Sort By&quot; to &quot;List&quot; (Cmd+2) if I wanted to return to my previous settings.
However, the usual Disclosure arrow found beside one particular folder is now missing and its sub-folders and files are permanently open and displayed instead of collapsed. How do I return the said Disclosure arrow? I'd like to have the ability to control when to expand/collapse it back if possible. This folder was open, by the way, when I was refreshing Finder, if that has any bearing. Thanks in advance
Weird little things like this can almost always be resolved by relaunching Finder. There's a number of different ways to do this, but I usually ctrl⌥-click the Finder icon and select &quot;Relaunch&quot;.
When that doesn't work, the next step is to turn the computer off and on again. Basic, I know, but there's a reason they're always mentioned.
