"Cannot perform this operation."

Question

"Cannot perform this operation."

I didn't have any error until I updated my mac to El Capitan.

However, after I updated it, there were some errors as I said,

And it made me to shut down Final Cut pro.

So I got a reset, downgraded, and reinstall,

but still, there are some errors when I put a new title.

Do you guys have similar problems like this?

Is this just a bug, or is this my mac's problem?

It soooooo annoying:(

I'm repeating once more that I had not have any error like this until I upgraded.

MacBook Pro (Retina, 15-inch, Mid 2015), OS X Yosemite (10.10.5)

You reverted back to an earlier OS version? Or to another version of FCP X? How did you do that?

If I confused you, sorry:(

What version number is your copy of Final Cut?

Can you post a screenshot of the error message you get when you add a title?

How much free space do you have on your boot drive and how big (total capacity) is the drive?

If there is another drive in your editing workflow, how is it formatted and how much free space is on that drive?

I just have reset it, so I don't have any other things.

I'm using 500GB one, and there is just FCP.

Maybe like 490 space?

It just means that I think it's not a problem with the free space.

Just about the main system drive when we press Control + Option + R.

Which named Macintosh HD.

I only have single drive.

WWhat's Control-Option-R? What are you doing? Where is the library you're working on?

ARe you doing a custom speed change?

Sorry for my awkwardness:(

I'm just working on 'library' folder.

Which means all the things are in the main drive.

But not a custom speed change.
