Q: Memory Usage not Updating After Deleting Photos

How did you backup your photos?

If you used Time Machine and the deleted the original files then your photos are now candidates for deletion from the Time Machine backup.

It appears your guess about what is using your disk space, by the way memory is usually used to refer to RAM, my suggestion is to download and install OmniDiskSweeper to find out the names of the files and folders which are using the disk space on your Mac. If they are not files and folders you created ask here before deleting anything.

Is Time Machine backing up to an external disk drive?

Don't bother with deleting them from Time Machine.

Please download and install EtreCheck from http://etrecheck.com/

Run it and post the report here.

You are getting a little low on hard drive space.

Have you tried emptying your Trash?

Try downloading and installing OmniDiskSweeper:

OmniDiskSweeper will sort your files by size and show you where they are located. This should allow you to determine exactly what you have on your MBP.

You may also be able to move some of these larger files such as videos, etc. to an external drive to free up space on your startup drive.

See the following video on OmniDiskSweeper.

I'm not sure what you mean by this.

From the bottom dock, right click on Trash, and click Empty Trash.

Is that what you are doing?
