How do I move my photos library to an external drive?

What are the step by step instructions for moving the new Photos Library to an external hard drive in able to free up space on my MacBook's drive?


I searched the forums and did not find anything related to moving the new photos library, not the old iPhoto library. A concern I have after reading through older threads is if videos will transfer over properly. I read that videos will turn into stills. I don't want to lose my videos. I plan on making a back up of my entire MacBook via Time Machine to a separate external hard drive before I even start this process at all but I want to make sure I do all of this correctly.


I have a MacBook Pro running OS X Yosemite version 10.10.3.

I will have 2 separate external hard drives. One for the MacBook back up and one for the photos library to be stored on.


Thanks!

MacBook Pro, OS X Yosemite (10.10.3)

Thank you for your helpful answers. I've been reading through replies trying to find an answer to my question: how do I get rid of files/photos that are preventing me from copying? I have tried to copy Photos to my external hard drive, it's formatted correctly, but then it says some info can't be found. I'll do it again so I can screenshot the image. I've also tried the "select all--> consolidate--> then copy" but in the middle of consolidating the following message pops up:

User uploaded file

I do not have an iPhoto Library folder. So, it seems that I cannot fix it...any help is greatly appreciated.

Ok but iCloud is not a backup as any change made using any connected device is made to all devices - and so far no cloud device has been shown to be successful at providing a usable backup of the Photo library - as Apple states you need a local backup


iCloud Photo Library - Apple Support

Back up your photos and videos

When you turn on iCloud Photo Library, your photos and videos automatically upload to iCloud. They're not duplicated in your iCloud backup. But we always recommend that you keep back up copies of your library. You can download your photos and videos from iCloud.com to your computer and store them as a separate library, transfer them to another computer with Image Capture or Photos, or store them on a separate drive.

Sounds like you actually did have a box that listed the files? Or did you have to click into something else to get a description of the files?

You will see, which files cannot be copied, if you copy the library in parts.

  • Create a new, empty folder "Photos Library Part" on the destination drive.
  • ctrl-click the Photos Library on your old drive and select "Show Package Contents".
  • Now drag each subfolder separately to the folder "Photos Library Part".
  • If a folder fails to copy because of the error message, look how far it copied and skip the files with the name conflicts. Copy them to a different folder, if it are media files you want to save .
  • Once all parts of the library have been copied, rename "Photos Library Part" to "Photos Library New.photoslibrary" and try to open it in Photos.

My situation has a slight twist and I just want to clarify before I dive in. I just bought a new MacBook Pro to ultimately replace my old MacBook. The old MacBook was upgraded to Sierra last fall, and that included moving from iPhoto to Photos. I also at that time enrolled in iCloud. Anyway the new MacBook Pro has a rather small hard drive, so I decided to move my photo library to an external drive (haven't done it yet). Looking in the Pictures folder, there is both an iPhoto library, and a Photos library. My first assumption was that the old iPhoto library had been superseded by the Photos library, but looking at the data, it looks like Photos is using the iPhoto library (iPhoto library is larger and last date of access is last time I used Photos, while the last date on Photos library appears to be when it was created back in October 2016) as its library, even though under Photos/preferences it shows that the Photos library is the current library. So, the question is, why is it doing this, and which of the two libraries do I choose when designating the System Library on the external drive?

You are probably correct. It does make sense that Photos would use the Photos library, not the iPhoto. After taking a second look at the two folders, it seems like I may have misinterpreted what I saw in finder about the new Photos library not having been modified since October. To answer your question, I do have iCloud Photo library enabled, and yes it is set to download originals to this Mac. I'm going to give it a shot tomorrow, as soon as I get the external drive set up.

I just got the EHD, a Toshiba 500 GB. I had planned on partitioning it into two 250 GBs and use one for Photos library and the other for Time machine (Photos library is about 75 GB). Are you saying that won't work? If no, I'll leave it as-is. I'm having difficulty doing even the partition. Disc utility lets me erase, rename and format the drive to Mac OS extended (journaled), but the partition button is always grayed out. Any ideas on that subject?

Of course not as I had no idea what you were have or were planning to do -- what I said was


What format is the EHD? For Photos it can only be Mac OS extended (journaled), not used as a Time Machine backup volume and connected with a fast wired connection

A correctly connected and formatted partition will work just fine

No that probably is a question best posted in the forum for your OS - it has nothing to do with Photos for Mac

'm running a 2009 imac on El Capitan for my 180 gig of images stored on Photos. I'd like to copy all the photos in the albums to an external drive formatted to exFat so they can be accessed by both my Mac and my PC computers, with each album converted to a file folder. Is there any way to do so, other than manually creating a folder for each album and copying the contents?

HI TD,

So i have followed the steps and copied my photos library to an external drive and now that's the default drive.

The question i have is, all the new photos imported will be copied to the external as long as it is connected, but how do I view the photos on my laptop when i am not around the external, as its a desktop drive i copied it to. Since this won't be backup by time machine how do i make sure there is a backup if anything does go wrong to the external. Any suggestions ?

Thank you

S
