iPhoto to Photos Library
I have an iPhoto library in old MacBook Pro with MacOs 10 that can't be upgraded anymore. I have backed it up in external drive using Time Machine. So basically my iPhoto library is still in MacOs 10. Now I have a MacBook Air that has macOS Monterey (12.6). How can I import my iPhoto library via Time Machine in my new MacBook Air? I have tried many suggestions that I have read here without success. Many thanks for your help.
MacBook Pro 15″, OS X 10.11
