Losing SSD space for no reason

When I look at my storage space it will randomly drop throughout the day. A few hours ago it was at 76.9 and now it's at 76.82 and I haven't downloaded anything. Just been using Safari.

What could be causing this? Even though it's not a lot of space I'm losing won't it accrue over time and become a problem?

Do you have Time Machine turned on? It creates temporary local backups that use some space.

Also, Safari creates a "cache" of web sites you have browsed, so just normal browsing will eat up some space like that.

Opening a terminal and running the following command will turn off the local backups:

sudo tmutil disablelocal
If you don't do that, your machine will basically fill up all of its free disk space. I'd recommend turning off local backups and using an external disk to make your time machine backups.

Also of note, the amount of space you saw disappearing is pretty minimal. Even if you aren't "doing" much of anything on the machine, programs may be writing to the disk. I wouldn't consider this to be a problem unless the free space decreases more significantly.

There really is no need to turn it off. If the space used by local backups is needed by the user, OS X will shrink the local backup space on its own.

It can be a useful feature for restoring accidentally deleted data when away from a Time Machine drive.

You can turn Time Machine off then back on to zero out the space if you want.

You don't need to watch it that closely - OSX will use small amounts here and there.
