With lots of talk about the new 2018 MacBook Pros currently, I thought I'd share some information on keeping older Macs running well.
High Sierra automatically checks EFI versions and will usually prompt at install time if an update is required. However I don't think it does the same for the SMC.
I recently noticed my 2012 MBP was running an old SMC version for some reason, even though High Sierra 10.3.5 had last updated the EFI to the latest version.
Apple have a support page listing EFI and SMC versions for models up to 2014, with links to updaters here: https://support.apple.com/en-us/HT201518
Note that the EFI versions listed will not be the latest available - installing High Sierra should take care of that, as Apple no longer issue separate EFI updates. However the SMC updates may be of use to people.
For more information on the latest EFI updates and which Macs have been updated as of the High Sierra 10.3.6 update please see the following useful webpage: https://eclecticlight.co/2018/06/27/which-efi-firmware-should-your-mac-be-using-version-2/
