Unity keeps force quitting on Mac no matter how small my action is?

It’s fine when I open the scene and play it, however sometimes when I zoom in or attempt to add something, fix the terrain a bit, the spinning wheel of death comes up and the application just disappears. My Mac is from 2011 and I feel it may just be my laptop being old, and quite possibly full, but is there any way to prevent Unity from force quitting? I’m willing to delete a few things from my computer, however I won’t if it’s necessary.

Thanks in advance.

Try repairing permissions in Disk Utility inside your Utilities folder.

Otherwise, how much memory do you have? Removing files from your hard drive won’t help unless it’s absolutely full.

The ‘spinning cursor of death’ is usually a system issue rather than [insert name of program], and requires more RAM.
