El Capitan - File Open Dialog Problem

When uploading a file, for example attaching a file in Mail, the finder-type Open Dialog does not allow files to be viewed in Cover Flow View, as in previous versions of OS X.

Is there any way round this or has cover flow now been dropped for the file upload window?

Cover Flow View works fine in normal Finder windows.

Cover Flow - workaround El Capitan

In reply to: El Capitan - File Open Dialog Problem

You are correct - seems that Apple has removed cover flow from the file open dialogue. A few pointers. First - if you do NOT change the view - cover flow is there when you first execute the file open dialogue procedure. If you change the view - i.e.: icon view - it goes away - never to return. I have replicated this on a number of my OS X machines. So - don't change the view. Second - here is a workaround - while NOT cover flow - it allows you to change the icon sizing in the file open dialogue procedure. This cannot be changed via menus and must be done by dropping into terminal.

/usr/libexec/PlistBuddy -c 'set FK_DefaultIconViewSettings:iconSize 220’ ~/Library/Preferences/

Copy and paste the above after executing terminal. This allows you to at least see images larger than standard icon view when uploading.

I suspect cover flow is fading away after the lawsuit Apple was faced with for copyright infringement. Google to find more on that.

Strangely enough - cover flow still exists in El Cap for file browsing - but has gone away for the open dialogue proc. Maybe it was an oversight - perhaps a deliberate release 'functionality'.... Hopefully we see the return in the next maintenance release.

Cover Flow - further thoughts

In reply to: Cover Flow - workaround El Capitan

Thank you for your helpful reply CDeSanno. At least you have confirmed that I am not being too stupid or missing a setting.

I am not aware of changing the View but I may well have done.

This does seem to imply that it is a bug as the behaviour is inconsistent? If Cover flow view can be seen in the File Open dialog then it must be possible. In this case it should be possible to edit a plist file or similar to restore the function?

The 'Column' View does give the option of image preview (selected in View Options) and does provide a similar image preview, it is not quite as good as Cover Flow though for quickly locating an image in a directory.

My best guess is that it is an unintentional omission. A very similar thing happened with Yosemite, Cover Flow in dialogs was not present in the Betas but was restored in the final release.

I don't think it can be connected with the copyright issue since, as you point out, Cover Flow is present in normal Finder use.

It is very odd though as the File Open dialog is obviously using Finder code.

I have reported this to Apple as a bug.

I listened in on a panel about the legal issue.

And it's too complex for me to write here. But it's true. The only good news is a recent patent troll got 130 cases thown out. But cover flow wasn't in that batch.

I know folk that are in denial about the trouble our patent system is in. They scream about feature losses like this and do not want to know why.

Does this code still work?

In reply to: Cover Flow - workaround El Capitan

I've been looking for a solution to increase the icon size for the file open boxes and tried this code and nothing happened. Does this still work with the current version of El Capitan? Thanks!

I have just spoken to apple as Coverflow was removed from the email attachment on the last software update. This was removed in the last software update they don't know why it was removed and said the only way to get it back is for people to complain to

So if you want coverflow back please complain it is still in the finder just not the email attachment part.
