Yes i see it, but You should know this is EFI for 820-3437-A, then i'm looking for a 820-3437-B, the A revision not working properly with second (B) revision.

Hi.

Dumped, updated to b04, you need to fix locale and ssn.

I'll check tomorow, but much thanks for U Wegeras. / Dzięki Wegeras, jak widzę w Polsce siła :)

Not working correctly, i think it's could be compatipility problem with SMC, becouse working only in safemode in normal mode system is frozen

U need tools: unpkg and maccommander in adminmode (cmd+0) to acces /

1. download smc update from apple website (pkg file), unpack it, find SmcFlasher.efi and YOURSMCNAME.smc and copy it to /
2. download efi update from apple website (pkg file), unpack it, find YOURSMCFILELOCKED.scap copy it to /

W A R N I N G !!!
EXTREMELY CAREFULLY CHECK IF *smc FILE IS 4 YOUR COMPUTER!!! MESSING WITH IT WILL TOTALLY FUCKED UP YOUR BOARD!!!
TO FIX IT THEN U NEED TO REPLACE SMC CHIP FROM SAME WORKING BOARD!!!

3. flash smc via efi shell. Use refit, type: SmcFlasher.efi -LoadApp YOURSMCNAME.smc next reboot to os(safe mode if not working in normal mode)
4. there is 3 possibilities, you can find witch 1 of them will work 4 u.
a) efi update via updates can be found in applemenu/updates, if not found there go to step "b"
b) efi update via package downloaded earlier -just double click on it . After reboot shoiiuld reflash your efi. If this step is either not working for you step "c" will be good.
c) efi update via terminal, open terminal type #bless -mount / -firmware /YOURSMCFILELOCKED.scap

If you do not have root access type $sudo bless -mount / -firmware /YOURSMCFILELOCKED.scap

thats all
