I can´t update the firmware
now im running MacOS catalina in the MBP mid 2012 and i have an old boot ROM version but when im going to update it says that a i need MacOS 10.9.5 so what can i do?Also the SMC version has the last one updated, so why is this updated but the rom no?
How have you updated your system over the years? Have you been upgrading each OS release in turn?
Also what is your current drive a HDD or SSD?

yes i have been upgrading but when swap to the ssd I install clean Mojave and then update to catalina and im currently using an ssd
the boot rom version that i have is 233.0.0.0.0
also, is necessary to do the SMC and nvram reset even when i have no issue?
