Defold not open in MacOS 10.9


I’m just trying to install defold on my old-fashion Mac with OS version 10.9.5 (cuz I noticed that the minimum requirement is 10.7).

However, the app I installed just exit once I open it. I’ve tried several times without even seeing the user interface.

Any idea?

Btw, I’ve try the unix executable file on app content, here’s how the terminal reports:

ok, i saw the “Unsupported macOS version”

sad day with my old laptop :worried:

It seems like the JavaFX update we did recently bumped minimum supported macOS version. Sorry about that!


So would you tell me the version without the update :joy:

Btw, time to update the page

I think the 1.2.188 editor is the one with the older JavaFX:

Hello everybody,

First of all I hope you are all doing great.

Today I had the same problem. I tried to start defold on my Mac and I couldn’t do it. It was odd. I then downloaded the latest version and still did not open. Then I went into the package files and launched the terminal and I got the terrible news:

`2021-12-18 19:59:35.286 Defold[5559:1185105] ERROR: macOS version is 10.11, which is below the minimum of 10.12`

I then download the version 1.2.188 and it opens ok.

So, do you think there is going to be a way I can overcome this? Or am I doomed to become obsolete?

Thank you very much and Merry Christmas!

We recently updated JavaFX to fix an issue on macOS Monterey and this had the side effect of raising the minimum supported version to 10.12.

If you have the ability to build Defold yourself you can downgrade JavaFX in the build configuration.

My old dev Mac is on 10.13.6 and can’t be (officially) updated. The end is near!

When mine is no longer useful as a Defold dev machine for macOS / iOS, I’m going to turn mine into a dedicated Linux box.


Hello everyone and thank you for your answer.

Oh, ok, so there is a solution, yeeeeeyyy!

Yep, mine is already there, boooo…

Uuuh, maybe you could post a sort of tutorial on that matter. :+1:

Anyway, thanks again, I’ll see if I am able to rebuild Defold with the older JavaFX.

Greetings and Happy Holidays!

This is the change you want to make and then build:
