Since the version 1.3.11 does not open on mac 10.11

I use a mac Intel Core 2 Duo from 2007, with version 10.11.6 of mac OS X, and I have tried to install some of the latest versions of Synfig Studio, but all from 1.3.11 do not open and give me a similar error.
The last ones that open without any error are 1.3.10 or 1.2.2.
I copy the application from the dmg to / Applications and when I double click, it jumps into the dock, but it does not show anything and after a few seconds I get an error message with:

I have also tried to open with control / open but the same thing happens. If I try to copy the application to an external disk, the same. Although in this case, some of the versions I don’t remember which one, I got a message first asking if I really wanted to open the program. When confirming, it still gave the same error message.
Looking at the downloaded dmg, I see that since version 1.3.11 the size goes from 106 MB to 69/75 MB.
Are there any changes that modify the application requirements? According to the initial web page you need 10.8 or higher. Which tells me that my 10.11 is compatible or should be, isn’t it?


P.S. Message translated mechanically since I do not speak English, I apologize if I have not expressed myself correctly.

@ice0 do you know anything?


@MacTerrassa just checked latest 1.4.0 ( on MacOS 10.10 and all works fine. So let’s try to understand why it doesn’t work.

Please try to rename folder ~/Library/Synfig to ~/Library/Synfig.old. This folder contains Synfig settings and autorecover files. After that try to run, preferably 1.4.0 just to make sure we are testing the same application.

Hi, I hadn’t been able to test yet, sorry, I apologize.
I have re-downloaded the version linked in your message, deleted the mentioned folder and a .synfig-gdk-loaders file in the first level of my user folder. Doing a search with EasyFind on the internal disk, it does not find any other files named synfig, except my email messages, diagnostic reports or recent files.
I double click on the program once copied to the main applications folder, and it keeps giving me the same message.
By the way, I have not deleted the version that works for me, 1.2.2 and in order to copy the new one, I change the name from the finder, why then does the system work by putting a forbidden symbol on the previous one that previously appeared correctly?
Also, now that previous version, with the name changed to SynfigStudio_1.2.2, it answers me that it cannot open it, which is corrupted or incomplete, is it related to my problem with the new versions?
If I rename version 1.4.0, it doesn’t change the icon, but it gives me the same message of a corrupted or incomplete application.
If the old 1.2.2 deleted the bookmark back to the original name, the forbidden icon still does not disappear, but it still opens perfectly. Is it related to my problem?

Hi! Sorry for a late answer.

There is an error where won’t start if renamed. But this is a different problem.
I made some digging and now I think I found the problem. The fact is that we using precompiled GTK and libpng libraries, and apparently now they do not support processors from 2007. Unfortunately, I don’t know how to fix this yet.

@KonstantinDmitriev any thoughts here?

I can note several things on that matter:

  1. Before version 1.3.11 we used OSX version 10.8 to build binary package.
  2. Since version 1.3.11 we use OSX version 10.9.
  3. Before version 1.3.11 we used MACOSX_DEPLOYMENT_TARGET=10.5 environment variable in our build scripts. After version 1.3.11 it was removed.

I did rebuild of libpng with MACOSX_DEPLOYMENT_TARGET=10.5 environment variable. Building testing package now…

I use a MacBook Pro from middle-2014:

  • Processor 2,2 GHz Intel Core i7 four cores
  • Memory 16 Go 1600 MHz DDR3
  • Mac OS X 11.0.1

I didn’t try all the releases but 1.2.1 is working with my computer. The 1.3.x I tried and 1.4.0 don’t work with my computer: no screen, no error message. Version 1.2.1 has a directory access issue which is described somewhere else in the forum. If I can help to clarify the failing…

I made rebuild of libpng with MACOSX_DEPLOYMENT_TARGET=10.5 environment variable, but it produces identical binary (I have verified by comparing checksums).

I am thinking the error produces on system of @MacTerrassa may be caused by bug in libpng. I can try to update version of libpng…

@treberna Hi! Can you please check version 1.2.2?

I downloaded SynfigStudio-1.2.2-20180914.dmg, uninstalled 1.2.1, deleted ~/Library/Synfig, rebooted and installed 1.2.2. When I ran it, a dialog box asked me if I wanted to open the program and then the program stopped immediately, without any information or error message.

@MacTerrassa Can you please try this testing package? - SynfigStudio-1.4.1-20210125.dmg

@treberna Can you please open Terminal window and then type the following command:


…and press Enter.

I need to see messages in Terminal window after this command.

Note to myself: In this version libpng is updated from version 1.6.34 to 1.6.37.

I have mac 11.1 and I tried synfig 1.4.1. It works but not completely, for example I don’t see the tool panel on the left, I cannot type text, and sometimes it crashes especially when I close it without saving.

Hi @silvershark! Thank you for reporting! Does version 1.4.0 works for you?

No, neither 1.2, 1.3 1.4 … they all have problems, in the first I can see the tool panels, in 1.4.0 no tool panel like 1.4.1. maybe it depends on some conflicts with other programs I have or it depends on the new version of mac os 11.1.

Try to run Synfig in 32-bit mode (Get Info on the app, check “Open in 32 bit Mode”)
It looks like an issue of bitness

Hi, I have not been able to test that version yet since I have been away for a few days and I cannot access the imac with system 10.11.
Right now, I just tested on another imac with Catalina, the original version 1.4.0 (20201114) and it opens perfectly and without any problem on this system.

Just to be confirmed, I have always discussed my problem with a 10.11 El Capitan system and an Intel Core 2 Duo iMac from 2007. I understand your problem is in the new 11 Big Sur system, just launched. Greetings.

Could you post a screenshot of what you get on 1.4.x?
