I want to know if my MacBookPro can be find with the app "Seach" on my iPhone

Do you mean can you use the Find My iPhone app on an iOS device can be used to see the location of your MacBook Pro?

If you have the find my mac setting enabled on your MBP (requires an iCloud account be active on it) then yes. The find my iPhone app should show all your devices - all the devices you have your iCloud account installed on and with find my device enabled. So not just mobile devices, but also all computers linked to your iCloud account.

No, sorry. Apple's system is tied to the iCloud account and that iCloud account ID. That is the only way to track it with Apple.
