Oct 18, 2019  The first backup may take a long time, depending on how many files you have, but you can continue using your Mac while a backup is underway. Time Machine backs up only the files that changed since the previous backup, so future backups will be faster. To start a backup manually, choose Back Up Now from the Time Machine menu in the menu bar. Mar 22, 2015  I have an iPhone 6 with iOS 8.2 on. I have enabled iCloud photo library (beta) and ticked 'optimise iPhone storage'. However on my iCloud backup storage options on my iPhone you can enable/disable what you want backed up. On my photo library it has 'no. Ever since Lion (OS X 10.7), Apple has hidden your personal Library folder (/Library) by default. In Lion and Mountain Lion (OS X 10.8), you could make the folder visible, but it required some work. You should poke around in /Library and see what's in there that you need. Here's a list of what I backup to get you started: /Library/Application Support and /Library/Preferences are where most of your application settings live. You should go through each of those folders' subfolders and see which ones you need.

An iMovie library holds all the media and data used to make movies in iMovie. If your iMovie library is large and you want to free up storage space on your Mac, you can move your iMovie library to an external drive.

Before you move an iMovie library, it's a good idea to back up your Mac.

Moving your library to an external hard drive doesn’t affect any iMovie Theater content you have moved to iCloud.

Prepare your drive

You can store your library on an external storage device such as a USB Thunderbolt drive formatted as APFS or Mac OS Extended (Journaled). Apple doesn’t recommend storing iMovie libraries on external storage devices like SD cards and USB flash drives, or drives shared on a network.

You can’t store your library on an external drive or other disk used for Time Machine backups.

Move a library to an external storage device

  1. Quit iMovie.
  2. Select your external drive in the Finder, then choose File > Get Info.
  3. If the information in Sharing & Permissions isn’t visible, click the triangle , then make sure the 'Ignore ownership on this volume' checkbox is selected. If it's not selected, click the lock icon to unlock it, enter an administrator name and password, and then select the checkbox.
  4. Click your desktop to make sure that you’re in the Finder, then choose Go > Home from the menu bar at the top of your screen.
  5. Open the Movies folder, then drag the file named iMovie Library to your external hard drive.
  6. When the library file is finished copying to your external drive, double-click the library file on the external drive to open it in iMovie. If an alert appears asking you to give iMovie access to a removable volume, click OK.
    If you clicked Don't Allow, in the Finder choose Apple menu  > System Preferences, click Security and Privacy, then click Privacy. Click Files and Folders in the sidebar, then select 'Removable Volumes' under iMovie.
  7. Make sure the library you moved contains all your media, then drag the original file from your Movies folder on your Mac to the Trash.

If you disconnect the external drive

When your external drive is connected to your Mac, the library you moved to the external drive opens automatically in iMovie. If you disconnect the external drive containing the library, iMovie opens to a new, empty library created in the Movies folder on your Mac. iMovie automatically saves any projects you create and media you import in the new library.

If you want to open the library you moved to an external drive, you can open it after you reconnect the external drive. You can then move clips, events, and projects between libraries.
