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?
