[doublepost=1547995977][/doublepost]This first post MP5,1: What you have to do to upgrade to Mojave have all the steps needed to upgrade your firmware. Please note that is a two step, the first one from your original firmware to MP51.0089.B00 then the second from MP51.0089.B00 to 140.0.0.0.0.

Even if you don't want to upgrade to Mojave or don't have a METAL GPU to do the upgrade, do the first part and upgrade to MP51.0089.B00. This firmware have the Spectre/Meltdown microcode updates.

[doublepost=1547997353][/doublepost]Thank you very much for idea. I'll try it.

Hi!
Now I have MP51.0089.B00, but neither wireless mouse nor keyboard. Fortunately I have an USB mouse, but no more keyboard. Will not change to wired. What should I do to recover them?

Connect a wired keyboard and do a clear PRAM. After that just open macOS and re-pair your Bluetooth devices.

All right now. So I'm protected against Spectre/Meltdown. Is there any more advantages of new firmware (if I just use Snow Leopard, Sierra and Win 7 via Bootcamp)?

138.0.0.0.0 enabled support for 5GT/s PCIe cards and with 140.0.0.0.0 now Apple supports booting from NVMe drives. Read here: MP5,1: BootROM thread | 140.0.0.0.0

To be fully protected against Spectre and Meltdown you need to use a least High Sierra. Snow Leopard don't have any mitigations against Spectre/Meltdown or any threats after July 2011.

Yes, it's true. And is sad. But internet security hardly ever vill be guaranteed.
You may say, I'm too conservative. Yes I am: after so many disappointments, bells and whistles I prefer downgrade to upgrade now.
Anyway, thank you very much one more time. Have joy with Macs!
