The application "DocDown.app" can't be opened

Question

The application "DocDown.app" can't be opened

Closed this issue 4 years ago · 22 comments

I'm not sure what has happened, but I now get that message when I attempt to open DocDown on my Macbook. I am running OS 10.15.2—was it the Catalina update?

Answer 1 · 2020-01-20T22:25:21.000Z

Hi! I've started looking into this and there are a number of issues which have emerged with Catalina which I'm currently looking into, so you'll have to bear with me!

Okay, sorry for the delay - see if the new release here works better for you! https://github.com/lowercasename/docdown/releases/tag/v0.4.0

Let's do some debugging! Could you:

Right click on the DocDown app and click ‘Show Package Contents’
In the folder that opens, go to Contents > MacOS
Double-click the file in that folder called ‘DocDown’

A Terminal window should open. Could you copy whatever output appears in there and paste it for me here?

Answer 5 · 2020-01-24T19:37:58.000Z

When I double click that it opens in TextEdit. Tried to force it to open in terminal but it won't do it. I can navigate into the package from the terminal--is there a command I could use there to try to run DocDown? ❦ ❦ ❦ Ryan Cordell | Associate Professor of English | Northeastern University | r.cordell@northeastern.edu | rccordell@gmail.com | @RyanCordell | http://ryancordell.org

Yes, try: ./DocDown, and when you're done, if it hangs, hit Ctrl+C to quit the app.

It looks like your Mac's security preferences might be preventing you from opening DocDown. Try going into System Preferences > Security, and see if there's a message there about DocDown, or an option to allow opening apps from untrusted providers (I can't afford the fees for an Apple trusted certificate unfortunately!)

Answer 9 · 2020-01-24T22:08:37.000Z

Also try right clicking on DocDown and then clicking 'Open', although if the machine has somehow managed to block DocDown from opening, that may not help.

Answer 10 · 2020-01-24T22:33:30.000Z

I've seen that security message before but it's not coming up now. Terminal says Permission Denied when I try to open the app from the command line, but nothing in security preferences. If I click on the app it opens in TextEdit. If I drag the app to the Terminal nothing happens. Not sure what to do next. ❦ ❦ ❦ Ryan Cordell | Associate Professor of English | Northeastern University | r.cordell@northeastern.edu | rccordell@gmail.com | @RyanCordell | http://ryancordell.org

Also following this thread due to same issue , have tried all of the above too, but getting same results as Ryan

Answer 12 · 2020-01-28T06:19:54.000Z

If I open a Terminal folder within Package Contents > MacOS and then type sudo /.DocDown, it prompts me for password - but says /.DocDown: command not found

Answer 13 · 2020-01-28T08:50:10.000Z

Try without sudo? Was DocDown working for you before?

Answer 14 · 2020-01-28T09:15:25.000Z

I had last version (0.3.2) working fine. Followed the update workflow and now not working. Also tried reinstalling 0.3.2 afterwards, but that's giving same error now

Answer 15 · 2020-01-28T09:19:03.000Z

If there's some way I can generate some useful debugging info to paste here, let me know 👍

Answer 16 · 2020-01-29T21:50:28.000Z

Same as @alistairwilson. Was working before the 0.4.0 install and now neither 0.4.0 nor 0.3.2 will open.

Answer 17 · 2020-02-03T11:28:58.000Z

Okay, let's all try the new version (0.4.1)! I updated electron-builder, and it's working for me on a machine where 0.4.0 was outputting the same error.

Same for me! Have tried right clicking and opening also, but no success

Answer 20 · 2020-02-03T17:04:40.000Z

Okay, never surrender - I've just switched the .zip file in that release with a .dmg file, can y'all see if that one works?

Answer 21 · 2020-02-03T17:32:50.000Z

.zip worked for me after I bypassed the Security setting in Preferences. Can we all gift you a Developer Account/Certificate? Ha!
