Before trying other things please make sure you downloaded and installed the latest version of LRTimelapse from http://lrtimelapse.com/download
Make sure you installed the LRTimelapse App into the Applications folder.
Unidentified Developer
If you get "Unidentified Developer" message from the GateKeeper in OS-X Mountain Lion, right click on the App and select "open". This happens because Apple is consequently expanding it's proprietary closed shop approach. You can find details about this here here.
Low Memory
By default LRTimelapse tries to allocate 2GB of RAM. If your machine has only less than 2GB of free RAM LRTimelapse won't start.
On a mac you can easily change the amount of RAM reserved.
Right click on LRTimelapse icon -> show contents. Find the file info.plist and open with the associated editor. Change the parameter -Xmx to a lower value.
Save and close.
Now LRTimelapse reserves less RAM but could as well run into memory problems later when you try to open large sequences.
Nothing helps!
Please open the Console (Utilities), click on "Clear Display", type LRT into the Serch field in the top right, now try launching LRTimelapse again.
Copy the whole output in the console window and send it to support (at) lrtimelapse (dot) com via EMail.
