OSX: Sierra/High Sierra/Mojave: Licecap captures black screen if two monitors connected EXTERNAL MONITOR ERROR

[esaruoho]

If I'm on monitor#2 on macOS Sierra/High Sierra - licecap captures a black screen on monitor#2. if I have monitor#2 connected, monitor#1 records black screen. i have to yank out monitor#2 to be able to get a non-blackscreen version from LiceCap. Detail: I do see my cursor moving in the animated gif, but everything else is black :)

hmmm I don't even have that option... what is you macOS version? I have 10.14.6

[woodyhayday]

Is it under Accessibility?

[dialex]

No :( Neither of the left side options show Licecap on the right side. I tried installing Licecap manually and through brew.

As @luis-admios said, adding to privacy & security seems to have fixed for me:

Perhaps all this bug needs is a prompt to load that mac setting if somehow accidentally dismissed without checking the box.

It seems that Catalina removed the option to manually give an app permission to record your screen. It seems the only time you can give an app that permission now is when it prompts you for it. Since licecap doesn't prompt you cant give it permission under normal circumstances.

I did manage to find a work around though. For some reason manually adding licecap to the Developer Tools list allows it to bring up the screen recording permissions prompt when you start recording.

I should mention that I can only get it working on my main monitor.

@dialex tagging you because I figure you'd be interested if you haven't fixed the issue on your machine yet

[dialex]

Thank you for caring @Meyer-Hallot 😉 I'm using Mojave and I don't that "Developer Tools" option. I manually added Licecap to the "Accessibility" option, but it didn't solve the issue 🤷‍♂️I already accepted this will never work again

This is still happening on Catalina.

I figured out how to get it working for me on both screens, but it's not the most ideal solution.

1. Close licecap
2. Make external display your primary
3. Start licecap
4. You should be able to record on both screens now

Changing my primary display back breaks it for me. I've tried several different combinations but the above is the only one that seemed to work for me.

I'm also only using one external monitor, so I can't confirm that this method will work on other setups.

* I used all the suggestions from the previous comments too

[ninamarina]

@cwalworth thanks! I'll try that :)

[NigelThorne]

I get blank screens unless I start LICEcap from the terminal as sudo.

[beifang721]

Ugh, I also met the same problem. Now I am very upset about what causes it? If the solution is expected to inform.

[stgarf]

I'm hesitant and sad to even suggest this since licecap generated smaller and higher quality gifs (imo) and has been such an excellent go-to for such a long time and I'm sure we'll eventually see some action here but in the meantime there's kap for macOS which works fine enough.

// Get the main screen. I may want to add support for multiple screens later
mainDevice = GetMainDevice();

I was browsing the code out of curiosity and ran into this comment in the code also.

[esaruoho]

closing issue. probably still happens. just bored of being notified about it for years on end. it's been 3 years.

[sanchezg]

Still happening for me.

[chriswoolfe]

Adding it here fixed it for me.

[KarlBaumann]

Broken. None of the fixes mentioned here work. Are there any alternatives to this app?

EDIT: I actually got it working after adding it to the Accessibility list

[anderoonies]

Sorry to the issue creator for another notification, but on Big Sur it appears this is now controlled by the Screen Recording setting in Security & Privacy

[joelPR]

For me worked doing these three things:

• Make the external monitor the primary one
• Mark Elapsed time in LiceCap
• Mark Use .GIF transparency for smaller files in LiceCap

Works for me, Thanks 👍

[sarink]

Licecap was already in my screen recording privacy settings... however, after removing it and re-adding it, the problem is fixed.
