Can someone help me with OChem? I need to propose a mechanism

here you go OP, i colored the sigma bond involved in and adjacent to bond breaking to make it easier to understand

Thanks a lot anon

How does that first mechanism make sense? The carbocation should be at the tertiary centre after rearrangement.

its correct though
If you'd get a tertiary carbocation instead, you wouldn't get the product seen in the OP pic. It works because of ring strain. In reality, some of that 5-membered ring secondary carbocation would still undergo further rearrangement to give the tertiary carbocation (and then tertiary alcohol) though.
