Before you begin

  • Update your Mac to the latest version of macOS.

Access all of your photos from anywhere

iCloud Photos automatically keeps all your photos in iCloud, so you can access them on your iPhone, iPad, iPod touch, Apple TV, Mac,, or on a PC. When you edit and organize images in the Photos app, your changes are kept up to date and visible everywhere.

Manage your iCloud storage

The photos and videos that you keep in iCloud Photos use your iCloud storage. Before you turn on iCloud Photos, make sure that you have enough space to store your entire collection. You can see how much space you need and then upgrade your storage plan if necessary.

Turn on iCloud Photos

It's easy to get started. Just turn on iCloud Photos in your Settings and make sure that you're signed in with the same Apple ID on all of your devices. On your Mac, go to System Preferences > iCloud and click the Options button next to Photos. Then select iCloud Photos.

Keep your photo library organized

On your Mac, your photo collection is separated into four main categories: Years, Months, Days, and All Photos. The All Photos tab shows all your photos and videos in chronological order. In Years, Months, and Days, you'll find your photos and videos grouped together based on the time and place they were taken.

The Photos app sorts your photos into Memories, Favorites, People, and Places in the sidebar under Library. The sidebar also shows what you and your friends have shared, your photo albums, and projects that you've created.

Learn more about organizing and finding your photos.

Do more with the Photos app

Your Mac is the place that you go to get things done. That’s why the Photos app makes it easier than ever to create a stunning slideshow, share with anyone you like, and quickly find the moment you’re looking for. All with a few clicks.

Play a slideshow or movie

You can prepare a slideshow directly in Photos with a few clicks. Open any album and click Slideshow. Customize the theme and music, then click Play Slideshow.

To play a movie, go to the Months or Days view, click the more button on any collection, then click Play Movie.

You can also view movies in the Memories section. Open a memory, then click the play button . As the movie plays, click the gear button to adjust the movie's mood and length.

Share with friends

Click the share button to share photos in Shared Albums, Mail, and more. Or send photos to your social media accounts, such as Facebook and Twitter.

Search your photos

Find the photo or video you're looking for in no time. Just use the search bar that's built directly into the Photos toolbar. You can search for photos using names of family and friends, locations, or what appears in the photos, like cake or balloons.

Delete photos and videos from your library

If there are photos and videos that you don't want anymore, you can delete one at a time, or several.

Delete one photo

  1. Select the photo that you want to delete.
  2. Press the Delete key.
  3. Confirm that you want to delete the photo.

Delete multiple photos

  1. Press and hold the Command key.
  2. Select the photos that you want to delete.
  3. Press the Delete key.
  4. Confirm that you want to delete the photos.

When you delete a photo, it goes into your Recently Deleted album, where it stays for 30 days. If you use iCloud Photos, the photos that you delete are moved into the Recently Deleted album on your other devices too. After 30 days, Photos deletes the photos permanently. You can permanently delete photos right away when you click Delete All in the Recently Deleted album.

When you delete photos directly from an album by pressing the Delete key, you only remove them from the album and not your entire photo collection. If you want to delete photos from both the album and your collection, press Command-Delete.

Edit your photos

Photos includes powerful, easy-to-use editing tools. You can apply adjustments to your photos and make them look exactly the way you like. Then if you want to start over, you can always revert to the original photo. Here's how to get started:

  1. From the Photos view, or from within an album, double-click the photo you want to edit.
  2. Click Edit in the upper-right corner of Photos.
  3. The editing tools appear along the right side of the window. Click the tool you'd like to use.

After you edit your photo, click Done. Want to start over? Click Revert to Original. If you use iCloud Photos, you'll see the changes on all of your devices.

With Photos for macOS High Sierra and later, you can also send a photo to most third-party photo apps for editing, then save the changes right back into your library. Learn more about editing your photos with third-party apps and extensions.

See and add information about a photo

You can also add details to your photos, like a description, keywords, or a specific location. You can even Add Faces to name your friends and family in each photo.

To view the Info window, double-click a photo to open it and then click the information button in the upper-right corner, or select a photo and use the keyboard shortcut Command-I. Once you add information, you can use the Search bar to find photos by keyword, title, description, faces, or location.

Apple’s built in pdf reader app called ‘Preview’ can merge 2 PDF files and edit PDF files. In macOS Sierra 10.12 all you need to do is drag the thumbnails that you want to merge from one PDF document to the other and then save the document.

Read on for some screenshots of what this looks like.

How to merge 2 pdf files

Apple have made a change in Preview in macOS Sierra so that when you drag a thumbnail from one PDF document to another, that page is automatically merged into the new PDF document, no matter where you drop it. This makes it really easy to merge two PDF files.

  1. Open the first pdf file.
    (Make sure it opens in Preview)
  2. In the View menu select ‘Thumbnails’
  3. Either:
    • Drag the a new pdf file from the desktop into this thumbnails window OR
    • Open the new pdf file then drag a page thumbnail across into this thumbnails window.

Here is a picture of the thumbnails window open, and I am dragging a PDF document into the thumbnails window:

4. Select “Save” from the File menu to save the new merged document.

An Alternate Method of merging pdf files.

Some people are reporting that this method doesn’t work. For some people even Apple’s own instructions do not work. If ‘saving’ the pdf file doesn’t work for you, then after you merge the files, instead of choosing ‘Save’ go to File menu and select ‘Print.’ Then don’t print, but select ‘Save as PDF.’ This will save the merged documents as a new pdf file.

If ‘Save’ doesn’t work, select ‘Print’ then ‘Save as PDF’.

I have tested both methods (Save and Print) on my Mac and they both work. You may have to try both and see which works for you.

Editing a PDF.

You can also edit a PDF document in preview. Read on for how to Edit a pdf file.

In attempting this I find that Preview continues to treat the 2 documents as 2 documents just combined in the one column. Not sure my question makes sense. :)
I’d like them to be treated as 1 document.

ReplyPaulsays:November 17, 2016 at 4:00 pm

I think I just solved this. You have to drag the second thumbnail directly onto the first thumbnail & not just below it.

ReplyWaynesays:December 11, 2016 at 3:10 pm

Paul do you have Sierra? Because the way you describe (dragging on top) is the way it has worked in every OSX so far, but in Sierra, for me anyway, I don’t need to drag on top to merge, I can drag below or anywhere. That’s not how it works for you?

I’m trying to edit a pdf document. i.e., change some words.
I’ve opened the toolbox but none of the new menu items seem to have anything to do with actually editing words and sentences.

ReplyWaynesays:March 29, 2017 at 12:54 pm

That’s right, you can’t edit existing words. You can only add new ones. It’s very limited.

After dragging one pdf to the open previewed pdf, it still treats the pdfs as 2 separate documents once i close preview

ReplyWaynesays:July 14, 2017 at 4:16 pm

Read these instructions more carefully. If that fails try printing the document then select ‘save to pdf’.

ReplyDonsays:August 27, 2017 at 3:46 pm

You are incorrect Wayne. I’ve read this (and many other) articles multiple times and still cannot get it to work properly.

Waynesays:August 27, 2017 at 7:13 pm

I just tried it and it works.
Are you sure you are using Mac OS Sierra (10.12)?
Do you get a little green plus sign when you drag one page into the other document?
What is not working?

The only way I got this to work on OS Sierra was to click Print and then in the bottom left corner selected “Save as PDF”

Thank you, thank you, thank you!!

Thank you for this sharing, really helpful. I used to merge multiple PDF files with Acethinker PDF Converter, it works pretty well. You just need to launch the app and Go to “Other Tools” tab to choose the “Merge” button. Then, click the files that you want to combine together or simply drop them into the selection box. Click “Convert” will start the combine process, once it’s done, you can save it to your computer. Share it here as an alternative solution.

Thank you–the first method did not work, but the alternate method of “printing” did.

Really nice post: very powerful tools in Previewer. If you had to merge lots and lots of files (e.g. 10+) you can always try Automator which comes with the OS. This allows you to set up a workflow to first ask Finder for items (i.e. your PDFs), then merge them (Combine PDF Pages) before finally moving them (Move Finder Items) to the desktop or some other place where you can find them. Over kill for most applications but sometimes useful to know.

Maybe the author can amend the article. As one of the posters said, you have to drag the second (and/or subsequent files) ON TOP of the existing file in the thumbnail window, not just underneath. If it’s underneath, it’s treated as a separate document.

Otherwise the Print/Save as PDF works fine as well.

The behaviour changes with pretty much every OS that Apple releases. Some you drag on top of and some you drag underneath. So you need to pick the exact article for the OSX version that you have! This article is for Sierra.
