Hi.
The 'similar issues' are not similar to your issue (only the last one might)
I do not have mac so i can't test, but you can give some more information.
What Playmaker Version are you using (find the exact version : PlayMaker/Help/About PlayMaker...)
How do you know that 'GuiText / GuiTexture' is the issues, as i can't see any clear indication on your pictures.
Also can you please use direct link to images and use the 'insert Image' (top left of text box above the smileys)
as we can see the images directly in the post then.
Have you tried building on mac or other platforms if you get errors?
What actions have you used.
If you think that the gui actions are the issue and you are not using them, you can try to remove them.
IF You Do, make a Backup of your project.
If it did not work maybe you can show some more errors that might narrow the issue.
