I'm getting "Your disk is almost full Save space by optimizing storage" alert, but I still have 60GB left on my disk according to "About this Mac/storage". I did have my MB Pro lock up recently because of this and I removed additional data from my drive, but am still getting the message. Help!

this happened to me, too. I think if you go to the disk utility you'll see the Data drive is full.

I deleted my bootcamp volume I wasn't using. If you can't do that, I'd contact Apple.

That's weird the disk utility shows it's full. It's maybe the 2nd account on the machine that's throwing it off. It says 62.19GB, 57.78 GB purgeable. What does that mean?

Do you use time machine?
If so, have you checked to see if "local backups" or "local snapshots" are clogging up the drive?
(these are normally invisible).

Download DiskWave from here:
It's small in size and free.

Open DiskWave and go to the preferences.
Put a checkmark in "show invisible files".
Close preferences.

The DiskWave window shows you all your drives in plain English (no ridiculous graphical formats).
Click on any drive or folder on the left.
Now, you'll see what's ON the drive, listed in order of "largest to smallest".
You can easily locate what's eating up your space.
