Hi! I’m in the midst of some confusing computer issues.
I’m new to mac, and I’ve put a huge number of pictures into iPhoto. Now all of my old and new jpeg files exist in the iPhoto Library in Finder.
If a few years down the road I get a Windows laptop, will I be able to transfer my iPhoto Library to my Windows “My Pictures” and still be able to access the files? The Windows computer wouldn’t have iPhoto, so does that mean it wouldn’t be able to view them? I’m really nervous about losing the ability to access my pictures.
Would it be safer not to use iPhoto? I really like the program, but I don’t want to lose accessibility if I need to use Windows. I have two external hard drives that I frequently use to back up my files, and both are Mac/Windows compatible. The issue is just if the iPhoto Library will be transferable or not.
Thank you SO much in advance for any help! Sorry if I was repetitive – I’m trying to wrap my head around this!

iPhoto is a bit tricky. You will find iPhoto Library in your pictures folder. You need to get the pictures out of that. Right click (Command click) on it and select “Show Package Contents” In there you will see a folder with the originals. From there you can drag them to a external drive. They will open without a problem on a Windows machine.

@thisisfun Thank you for your help!! I love the idea of being able to get the pictures out of iPhoto. I followed through and did the Show Package Contents, then clicked on the Originals folder. However, the Originals folder was only 4KB big (and I have about 200GB of pictures) – and didn’t contain pictures. Does this mean iPhoto doesn’t have the originals?
Thank you, again!!

@hellolulu No, it doesn’t nessesarily mean that. If you’ve edited a photo, it puts the original version of it in the original folder. If you haven’t touched it up or anything, it wouldn’t be in the original folder.

Back up your library

Before following any of these steps, it's a good idea to create a backup of your photo library, even if you use iCloud Photos. You can use Time Machine, use a third-party backup solution or copy the library to an external drive. By default, your photo library is stored in the Pictures folder within your home folder.

Make sure your software is up to date

Photos is part of the Mac operating system. You can avoid or fix many issues by running the most up-to-date version of macOS.Learn more about updating the software on your Mac.

If you have trouble migrating an existing iPhoto or Aperture library to Photos

You might see an alert message when you first open Photos or migrate an existing iPhoto or Aperture library. Learn what to do if Photos can’t copy or create a library.

If the Media Browser isn't showing your photos and videos

Use the Media Browser to make images from your photo library available in other apps, such as Pages and iMovie. The Media Browser shows only the contents of the Photos library designated as the System Photo Library. If you have more than one Photos library – and the one you're using isn't set as the System Photo Library – the Media Browser won't show its contents.

Follow these steps to designate the current library as the System Photo Library:

  1. Choose Photos > Preferences.
  2. Click the General button at the top of the Preferences window.
  3. Click Use as System Photo Library.

If you're having other issues with Photos

If you're experiencing other issues – such as missing or blank photo thumbnails, unexpected behaviour or if Photos won’t open – try to see if it's an issue with your library by following these steps.

Create a new Photos library and see if your issues persist:

  1. Quit Photos.
  2. Press and hold the Option key while you open Photos.
  3. In the dialogue that appears, click Create New.
  4. Give your new library a name, then click OK. Note whether Photos opens successfully with this new library.

How To Open Another Photo Library On Mac

To return to your main Photos library, quit Photos. Then open it again while holding the Option key, select your main library, and click Choose Library.

Cannot Open Photos On Mac

Alternatively, you can open Photos in another user account on your Mac and note whether Photos opens successfully.
