Freeing Up Space on The Hard Drive

1. See Lion/Mountain Lion/Mavericks' Storage Display.

2. You can remove data from your Home folder except for the /Home/Library/ folder.

3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.

4. Also see Freeing space on your Mac OS X startup disk.

You must Empty the Trash in order to recover the space they occupied on the hard drive.

You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.

Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

I have a MacBook Pro (< 1 year old) with a 1 TB boot drive running Mac OS X 10.10.5 and over the last few months I watched its available space run right down to 55 GB !!!! All of my own files are on external drives, so I have no idea what was filling it up. To avoid the dreaded *disk full* error, I reinstalled Mac OS X using the command-R reinstall procedure without erasing the disk beforehand,. The reinstall was not very graceful, but when I was finally able to login again, all of my applications were still there and operational AND my available free space on the 1 TB boot drive was 915.68 GB.

Hopefully others can solve this dilemma in the same way.
