Help and insight needed. To much HD being used for apps

[JWorld127]

Hello.

I have a serious concern. when I open my about mac and look at how much HD is being dedicated to the certain areas on my computer I see now 89 gb being used under apps. I know for a FACT i do not have any where near 89gb of apps on my computer. When I perform "control I" on apps in finder it says only 8gb so there goes that theory. About two weeks ago before i did the latest OSx update i had about 98 gb free on my hard drive ( computer is a 15'' MBPR with 256gb) and now it says only 82.57 gb available.

Does anyone else have this problem? Is there a solution? I do all my time machine backups on an external HD. Any ideas as to where all this hard drive space is being used?

Thank you.

You can use an application like OmniDiskSweeper which will show you exactly what and where takes the space on your drive.

Thanks dude! i just downloaded it and found 56gb in a back up file. Any way to know why it does this? When I click on TM settings it shows my External hard drive as the back up location. Why would it save back up to the lap tops hard drive? Also I turn off TM after i do my back ups so there is no way it does it on its own.

Thanks again.

For Time Machine users on notebooks running Lion or later, space may being consumed by Time Machine local snapshots, which can be disabled by entering the following command in Terminal: sudo tmutil disablelocal.

About Time Machine's "local snapshots" on portable Macs​

While you can disable local snapshots, it's not really necessary, as Time Machine manages space automatically:

Do local snapshots take up disk space?

Time Machine is designed to store local snapshots only when there is plenty of free disk space on the startup disk. This means that you can keep using your available disk space when you need it.

If your disk is low on space, Time Machine stops creating new snapshots. Some or all snapshots may be removed to make space available for applications to use. If sufficient disk space becomes available again, Time Machine resumes creating local snapshots. This means your disk has the same amount of available usable space as it would if Time Machine were not enabled. Time Machine uses the rules below to determine whether to stop creating snapshots, or to remove existing snapshots.
