I am still a bit new to the whole mac world and I have managed through trial and error to install a program for animation. I installed it through mac's homebrew in the terminal. The problem is when it starts up, it crashes with a error. I contacted on the sites forum about this issue and currently there aren't any knowledgeable mac users that can help. That is why I am here. The program I am trying to run is synfig studio, a program for animation. I do have pencil 2D but unfortunately that isn't enough to suffice for the project I am working on. And I am not a fan of flash or toon boom. Honestly I bought the mac for my expert animation needs but I am thinking linux now with all this frustration. If anyone is kind enough to help a student animator in solving this problem, please do, I would be so thankful and the community at synfig would be too. The error I am receiving when I start up in the terminal is : synfig studio -- starting up application... synfig(1378) [13:38:14] info: Loading modules from /usr/local/Cellar/synfig/0.63.03/etc/synfig_modules.cfg (synfigstudio:1378): GLib-GObject-CRITICAL **: Object class gtkmm__CustomObject_N6studio15ValueBase_EntryE doesn't implement property 'editing-canceled' from interface 'GtkCellEditable' synfigstudio(1378,0x7fff7e491960) malloc: *** error for object 0x10bc5b168: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Abort trap: 6 I am running Mac OS 10.7 lion on a macbookpro Thank you all!
