You can store your library on an external storage device, such as a USB or Thunderbolt drive formatted as APFS or Mac OS Extended (Journaled).1 Find out how to check the format of your external storage device.

To prevent data loss, Apple doesn't recommend storing photo libraries on external storage devices like SD cards and USB flash drives, or drives that are shared on a network.

Move your Photos library to an external storage device

  2. In the Finder, go to the external drive where you want to store your library.
  3. In another Finder window, find your library. The default location is Users > [username] > Pictures, and it's named Photos Library.
  4. Drag your library to its new location on the external drive. If you see an error, select your external drive's icon in the Finder, then choose File > Get Info. If the information under Sharing & Permissions isn't visible, click , then make sure the 'Ignore ownership on this volume' checkbox is selected. If it's not selected, click to unlock it, enter an administrator name and password, then select the checkbox.2

What are log files and what do they do?

Log files are a journal of system parameters and entries describing everything that takes place on your Mac. Any operation that is being performed at any time is noted down in the form of logs, much like a “black box” on an airplane.

For the most part, logs contain crash reports and app errors. To us, regular users, this information bears no sense because it’s unreadable. But when you need to diagnose a problem, log files are an indispensable invention.

How to clear log files on a Mac manually

  1. Open Finder and select 'Go to Folder' in the Go menu.
  2. Type in ~/Library/Logs and hit Enter to proceed to this folder (pay attention to the use of “~” — this will ensure that you’re cleaning user log files, not the system log files).
  3. Optional step: You can highlight & copy everything to a different folder in case anything goes wrong.
  4. Select all files and press Command+backspace.
  5. Restart your Mac.
    Note: We recommend that you remove the insides of these folders, but not the folders themselves. Also note that some system applications, like Mail, have their own logs stored elsewhere.

Remember, if you want the additional space from cleaning these log files, be sure to empty your Trash. To do this, Control+click on the Trash icon in the dock and select “Empty Trash.”

In addition, some log files can be found in the /var/log folder, but not all the items contained therein are safe to remove. That’s why it is safer to remove log files using a Mac cleaning utility like CleanMyMac X.

Make sure that once you have finished clearing out these logs for additional hard drive space, you empty out your Trash. To do this, Control-click on the Trash icon in the dock and select “Empty Trash.” Restart your Mac afterward so your Mac can begin to create new log files.

Many experienced users prefer to clean their user logs as part of their Mac cleaning routine on Mac. Though it doesn’t directly translate into speed, there is some benefit in keeping your disk clean. Some apps have notoriously large log files, especially media apps. For example, writing this article I’ve found a single log file by Elmedia player that weighted 325 MB.
