Also: (this issue has been for every version of OSX) copying and pasting text does not seem to work at all, it seems that the clipboard interface is broken.
Since i have upgraded to mavericks, I have also experianced TPT acting up in strage ways.
1. It hasn't been able to load stamps/saves
2. It doesn't let you save a new game
3. I get a message everytime i open the game stating that "you don't need to install powdertoy on mac osx"
btw, great work on creating virus/protons.
When I downloaded Powder and opened it...... It said that it couldnt be opened because it was from an unknown developer. And btw I'm on OS X Mavericks because it's more important than an unrealistic physics game
If you are going to update to mavericks right now, then you really have no room to complain about things not working. It is a new release, Apple is legendary for their lack of any sort of API stability, so it is not exactly surprising that the update would break some software. Just give the devs some time to work out the issues.
The developers are trying to address the issue, what more do you want?
Go into System Preferences and change the setting in System preferences>Security and Privacy
and check the box that says "allow apps downloaded from Anywhere"
He's/She's an utter waste to the TPT community, how dare he say it is a unrealistic physics game? Probably because he failed the class.....meh.
