Stolen Macbook Pro, how easy is it for thieves to break into it?

First have to get by the Apple lock.

¿Was the drive encrypted?

If yes, then cracking a strong password by brute force takes longer than a decade of supercomputer time. Unless you do both, the data remain encrypted, and when read are gibberish, unless you used "password" or "123456", where no cracking is needed..

Hello ashli44,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you have questions about how to protect your data on a stolen MacBook. To start, check out the information listed in this article for what to do if your Mac is lost or stolen to protect your data: If your Mac is lost or stolen

Please note the section titled "If you can't find your Mac or didn't set up Find My" for more steps to protect your data.

We hope this helps.

Cheers!

No one is going to tell you if it is easy to outsmart the password. Ask any hacker and they'll tell you. And no one would know how likely it is that the thief will try to boot up and the Find my is activated. Those are statistics which everyday users would have no access to. And, lastly, if a hacker manages to outsmart the technology and get in, they will change the Apple ID and password and, no, they will not return it to you. They wanted a device - that is why they stole it.

I would erase it as soon as it is possible and report the theft to not only police, but my homeowner insurance carrier to see if it is covered.

Unfortunately, Apple does not have such a database.

And, "anecdotal" implies personal experience - on a site owned by Apple, it would not be wise for anyone to proclaim that they've hacked into a device they stole. You may or may not find such information elsewhere online, but certainly not here.
