Downloading pictures to my Mac

Hey there virginiadm, 

If you'd like to learn how to free up space on your Mac, you'll want to follow the guide we've linked below.

Free up storage space on your Mac   

"Free up storage space in other ways

• Delete unneeded media, such as music or movies or podcasts, which can use a lot of storage space.
• Delete unneeded files in the Downloads folder. You can open the Downloads folder from the Dock or by choosing Go > Downloads from the menu bar in the Finder.
• Delete unneeded email in the Mail app. To delete junk mail, open Mail and choose Mailbox > Erase Junk Mail. To delete mail that you've moved to the Trash, choose Mailbox > Erase Deleted Items.
• If your Mac is set up for multiple users, remove users that you no longer want to have access to your Mac, or ask them to follow the steps in this article after logging in to their user account. Also check the Users folder on Macintosh HD for any undeleted data belonging to previously removed users.
• Check the Users folder on Macintosh HD for any shared files that you no longer need to share.
• Move some of your files to external storage, such as iCloud Drive* or an external drive connected to your Mac.
• Uninstall apps that you no longer use. 
• Compress files that you use infrequently."

Have a good one!
