deletingdisk-spacemacos
I'm looking for anything that can be deleted and that don't required by system to work properly.
So far I'm delete DVD Player.app, Chess.app, Photo Booth.app, Stickies.app, Dashboard, Launchpad.app and Mission Control.app (still works after reboot with gestures!)
In terminal.app:
sudo rm -rf DVD\ Player.app
What else ?
If you want to free up some disk space: How can I free up some disk space?
I had similar issue where the used disk space shown in Finder was about 20 GB more than what the size of all files should have been.
When I tried verifying the main OS X volume (like Macintosh HD; not the drive) in Disk Utility, there was an error about an invalid free block count. I was able to get rid of the error and free up the disk space by starting up from the recovery partition and repairing the volume.
It's likely in /Volumes/MobileBackups and you can easily delete it by entering Time Machine and navigating to the folder where the file existed. Select the file then command-click (right-click) and delete all backups of that file.
Normally, the system information window shows the backup space, but I have seen this window get hung up and not properly report storage space when Spotlight and/or the disk catalog are wonky.
You can also wipe all local backups by disabling the local store:
sudo tmutil disablelocal
If the above steps doesn't work, you'll want to boot into recovery mode and run Disk Utility to check that the directory structure and file system catalog are correct. A fsck -fy / in single user mode is also equivalent if you are so inclined to fix things from terminal or want to perform a safe boot and have the system clean things up systematically.

Most of the applications you'll delete are going to be restored the next time there is a software update, and even still it'll only save superficial amount of space. For example, the Mission Control, Launchpad, Dashboard, Time Machine, etc. apps are all less than half a meg, and only serve as links to call upon these features via Dock or Finder.
If you want to make a substantial cut on space without making your mac bulimic, i suggest Monolingual, which deletes unused language support (which is usually around 500 MB to 2 GB) and redundant app binaries.
Most Mac apps are "universal," meaning they support both Intel and (the older) PowerPC processor architectures, by having every application contain a binary compiled for each. If you're running an Intel Mac, monolingual can be used to delete the unused app binaries, saving 1-2 GB
