Saving pictures from Facebook to your Mac is pretty simple and straightforward, however many people do not know how to do it (probably including you, since you're reading this).
Below I've set out a tutorial with images that shows you exactly how to save a picture from your Facebook timeline to your Mac's hard drive. The tutorial used a Mac running Google Chrome, however, the process remains the same even if you're browsing on Safari or Firefox.
1. Firstly, navigate to the page where the picture is located that you want to download.
2. Now click on the image, wait for it to load. Once it is loaded, right-click on the picture and navigate to 'Save Image As'
3. Now select the location you wish to save to and a file name, and you're done!
