Photos in your System Photo Library are available in apps like iMovie, Pages, and Keynote. You can also sync them to iOS devices and view them on Apple TV. And if you want to use your own images as your desktop picture or screen saver, the images need to be in your System Photo Library before you can select them in System Preferences.

Mar 18, 2020 Your Photos library holds all your photos, albums, slideshows, and print projects. If your library is large, and you want to free up storage space on your Mac, turn on iCloud Photo Library and use Optimize Mac Storage, or move your library to an external drive. Jun 04, 2019  The company confirmed that when Mac users update their software, music currently in your library will transfer to the Apple Music app and TV and movie purchases will migrate to.

If you have only one photo library, then it's the System Photo Library. Otherwise, the first photo library that you create or open in Photos will become the System Photo Library. If you have more than one library, you might need to designate a System Photo Library, so other apps can access the photos and videos you want them to use.

How does your library shelve the Macs and Mcs? Since I've worked at my library, we've shelved all the Macs and Mcs as if they are Mac, regardless of how the author spells their name. So shelving in order would be Maa, Mabery, McDonald, MacMullen, McPherson, Mansell, etc. The network library, /Network/Library would store settings shared by all computers in a network domain - if a network domain admin set one up, which nobody does anymore; The system library, /System/Library, stores the base settings, resources, etc that come with OS.

Follow these steps to designate a System Photo Library:

  1. Quit Photos.
  2. Hold down the Option key and open Photos. One of the photo libraries is already designated as YourLibraryName (System Photo Library).
  3. Choose the library you want to designate as the System Photo Library.
  4. After Photos opens the library, choose Photos > Preferences from the menu bar.
  5. Click the General tab.
  6. Click the Use as System Photo Library button.

What Does Mac Store In The Library Hours

If you open a second or different library in the Photos app, and you haven't designated it as the System Photo Library, other applications will use photos from the original System Photo Library. Hold down the Option key when you open Photos to see which library is set as the System Photo Library.

iCloud and the System Photo Library

You can use iCloud Photos, Shared Albums, and My Photo Stream only with the System Photo Library. If you choose a different library in Photos without designating it as the System Photo Library, the iCloud tab in Photos preferences is disabled:

If you designate a new library as the System Photo Library and then turn on iCloud Photos, the photos and videos in the new library will merge with those already in your iCloud Photos. If you want to keep the contents of your photo libraries separate, don’t turn on iCloud Photos for more than one library in Photos.

As we use desktop and laptop computers, we tend to fill up our hard drives with stuff we've collected over the years. It's like an attic, basement, or garage that slowly fills up over time. Some stuff gets used often, other stuff sits in a box and gets forgotten about. Eventually, though, the clutter becomes too much and you have to start getting rid of things. But how do you sort the import stuff from the trash? That's where Optimized Storage comes in.

Optimized Storage takes files you've been storing in iCloud and moves them off of your computer if your local storage gets too full. It also leaves behind an icon of the item that has been removed so that, when you finally do want to access it again, you don't have to go somewhere different to find it. You can just click on the file and it will download back onto your computer when it's online.

There are four features to Optimized Storage that you can enable separately or all together. You can use Store in iCloud, Optimize Storage, Empty Trash Automatically, and Reduce Clutter.

How to access Optimized Storage

There are two ways to access Optimized Storage. The first is easy. Do nothing until your storage gets full. When it does, you'll get a notification asking if you want to optimize your storage. Click Yes to be directly taken to the Optimized Storage tool window.

To access Optimized Storage manually:

  1. Click on the Apple icon in the upper left corner of your screen.

  2. Select About this Mac from the drop-down menu.

This opens up the four Optimized Storage tools, which are on the right side of the window.

How to use Store in iCloud

Store in iCloud allows you to store older photos, files, and messages in the cloud, freeing up space on your hard drive. Messages stay on your hard drive until your hard drive starts to get full. When you're running out of room, photos, files, and messages will automatically be stored in iCloud and only recent attachments will stay on your Mac for quick and easy access.

It also only keeps recent email attachments on your Mac when your hard drive starts to run out of room.

How to use Empty Trash Automatically

It is pretty common for the average computer user to forget to empty the trash bin regularly. Just like a real garbage can, trash can start to add up. Unfortunately, unlike a garbage can, your Mac's trash bin doesn't get full, so you don't realize you've been stocking up digital waste for months and months. Empty Trash Automatically will enable a tool that will erase items that have been in the Trash for more than 30 days. You don't even have to think about it anymore.

  1. Click on Turn On in the Empty Trash Automatically section of the Optimized Storage window.

  2. Click Turn On again to confirm that you want to enable the feature to automatically erase files that have been in the Trash for more than 30 days.

How to use Reduce Clutter

Reduce Clutter is the one feature in Optimized Storage that requires you to manually clean files on your Mac.

The list of categories on the left side of the Optimized Storage window represents the folders that tend to store files that are older and can be removed from your Mac.

You can either click on Review Files in the Reduce Clutter section of the Optimized Storage window or select a category from the list on the left side of the window.

You can then go through the files individually and decide whether you want to keep or remove them from your Mac.

For example, in the Applications folder, you can view apps on your Mac by type. Older versions of apps you are currently using can sometimes take up dozens of GB of space. You can delete the files right from the Optimized Storage window.

How to optimize your photo storage if you have iCloud Photo Library

Photos on the Mac optimizes storage by letting you store full-resolution photos and videos in iCloud instead of on your internal hard drive. Even if you don't want to store all of your files and documents in iCloud, you can keep your photos safe, while freeing up space on your hard drive.

Your photos will also remain on your Mac's hard drive until it starts to get full, at which point, photos and videos — starting with the oldest — will be removed from your Mac and only stored in iCloud.

What Does Mac Store In The Library Store

Photos and videos tend to take up a lot of space. You may find you don't have enough iCloud storage to keep your entire photo library in iCloud. You can upgrade your iCloud storage to a larger plan if you are running out.
