By default, iPhoto is a photo management program which comes standard on every Mac computer. But if you want change your Mac computer to Windows PC, then you need to transfer you all data from Mac to Windows PC. The most important thing is your photos and videos. You can transfer all your photos from iPhoto to Windows with simple steps. To do so, open 'iPhoto' on your Mac and select all your photos to transfer. Click 'File' menu and select 'Export' option. A 'File Export' window opens up. Select 'Original' option in 'Kind' and 'Event Name' option in the 'Subfolder Format' and then click 'Export' button. This will give you the photos in folder which represents the 'Events' in your iPhoto Library. Now you must export the entire event to Windows PC. Go to 'Events' view and select the event which you want to export. You may have to export all photos by year to make file management easier on the Windows PC. Make sure that you have enough storage space on your hard drive before doing this procedure. If you don't have enough storage space, then hust export a few albums from iPhoto and then delete them. If you choose 'Original' in 'File Type', iPhoto will not embed the keywords and GPS data in your exported photos.
Quick Tip to ensure your Photos never go missing
Photos are precious memories and all of us never want to ever lose them to hard disk crashes or missing drives. PicBackMan is the easiest and simplest way to keep your photos safely backed up in one or more online accounts. Simply download PicBackMan (it's free!), register your account, connect to your online store and tell PicBackMan where your photos are - PicBackMan does the rest, automatically. It bulk uploads all photos and keeps looking for new ones and uploads those too. You don't have to ever touch it.
Prepare your external drive
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). However, you can't move your library to a disk that's used for Time Machine backups.

I, too, am having trouble importing my old iPhoto Library to my new iMac. I used Migration Assistant and the iPhoto Library from my old iMac is now on my new iMac. But I cannot get it to import into the iPhoto 09 that is on my new Mac. (I have iPhoto 08 on my old iMac.) (1) There are no photos in the iPhoto 09. If you go to your home directory, there is a folder called ‘Pictures’ where Apple stores all your photos. If you have used iPhoto, then in the ‘Pictures’ folder there will be a file called ‘iPhoto Library’. It appears as one file. Don’t do this, but if you were to click it then it would try to open in iPhoto, or Photos.

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
- Quit Photos.
- In the Finder, go to the external drive where you want to store your library.
- In another Finder window, find your library. The default location is Users > [username] > Pictures, and it's named Photos Library.
- 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 the triangle , then make sure the 'Ignore ownership on this volume' checkbox is selected. If it's not selected, click the lock button to unlock it, enter an administrator name and password, then select the checkbox.*
- After the move is finished, double-click Photos Library in its new location to open it.
- If you use iCloud Photo Library, designate this library as the System Photo Library.
Delete original library to save space
After you open your library from its new location and make sure that it works as expected, you can delete the library from its original location.
In a Finder window, go back to your Pictures folder (or whichever folder you copied your library from) and move Photos Library to the trash. Then choose Finder > Empty Trash to delete the library and reclaim disk space.

Open another Photos library
If you have multiple libraries, here's how to open a different one:
- Quit Photos.
- Press and hold the Option key while you open Photos.
- Select the library that you want to open, then click Choose Library.
