I have a 15 inch mid 2010 Macbook pro, running macOS Sierra 10.12. I still get bus error 10, similar to what I got with the previous release. I have also updated my OS recently - it didn't change a thing.

What happens when I run Monero daemon is this (identifying information omitted with XXXXXXXXX):

BUS error most likely happens when you have a corrupt database, which causes the LMDB code to try to access an invalid memory page, causing the SIGBUS.

Unfortunately, it means you have to delete your data.mdb and resync from the network.

If you're seeing this, it might be prudent to set a "safer" database acccess mode. See Why does my bitmonero fail to load?
