No space left on Startup Disc! HELP

[sstevens]

I have a 256GB SSD for startup and applications and a 1TB HD for all my documents, music, etc.

I have <700MB available to me now.

I recently began editing a video in Final Cut and so "imported Media" of about 70GB and I saw it was using that on my SSD, "Macintosh HD". Why?

What is it that's using so much space? I have almost no extra Apps installed:

What Can I do? When I imported the media into Final Cut I "copied" the files which I assume is what sucked up so much space this last time. But in reality, I should have over 100GB available. wtf? please help!!! Can provide screenshots as needed. I really need to fix this, my computer is running so slow.

Get yourself a copy of Daisydisk from the Mac App Store. That will show you graphically what is taking space on your SSD.

Another app to try is "Grand Perspective".

Another app to try is "Grand Perspective".

Which is free.

Presumably that's where you imported it to. Does Final Cut give the option to import it to your external drive?

you can import it, final cut should give u an option

This will help and is way better than the garbage app above:

Thanks, sickboy.

Of all the "disk space" apps I've seen, DiskWave is the most useful...

Download and use OmniDiskSweeper. It will provide a sorted list of what's consuming your space.

If you run it with sudo (As shown below), it will include some system files that it woud not normally have access to scan. That is a more accurate representation of what's consuming your drive.

sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper

Another option is to use this terminal command
sudo du -d 1 -x -c -g /

I prefer to redirect it to a text file (this puts it in your Documents folder
sudo du -d 1 -x -c -g / > ~/Documents/du.txt

Like the sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper command, it will scan all directories, but produce a text file as opposed to showing the results in a window
