Freezing/Crashing on MacOS

1) DS crashes when I either try to create new project or open the one I made before.
 
2) Choosing a folder for a project (using this option freezes whole computer for couple of seconds, then it works for about 2 seconds and again freezes, so it's difficult to do that. Happens also when adding new Assets using "Add new Assets" button)
