Migrating from 10.5 to a new Mac 10.11
I am helping a neighbor to purchase a new MacBook. I will need to migrate their accounts, email, etc. from their old Mac to the new one. They have an old PowerPC iMac running 10.5.8 . From my research so far, I know that PowerPc Macs can't be upgraded past 10.5.8 .
What steps do I need to take to migrate their old data from 10.5.8 to a new MacBook running 10.11 El Capitan ?
iMac, Mac OS X (10.5.8), Not my Mac
