thecliffhanger Posted January 8, 2017 Share Posted January 8, 2017 Hello folks, i recently purchased a macbook pro 9,2 (mid 2012) from Sweden. Everything is ok changing language and text from preferences panel, the only swedish texts still remain are in login menu (multiple accounts) and in boot + option keyIs there a way to change the boot rom/efi language, maybe flashing it? I've found this article in apple's support https://support.apple.com/en-us/HT201518, where the latest boot rom MBP91.00D3.B0C is actually different from the one on my mac MBP91.00D3.B0E. In order to change boot rom i have to downgrade my os 10.12.2 to 10.9.5 (.pkg require)Otherwise something here http://apple.stackexchange.com/questions/103720/how-to-downgrade-efi-firmware-back-to-version-1-6 and https://it.ifixit.com/Answers/View/337306/EFI+and+Firmware+update+from+4,1+to+5,1+for+Sierra+Upgrade+SolvedAny idea and help?

smolderas Posted January 8, 2017 Share Posted January 8, 2017 Ehm, you don't need to flash anything IMHO. You just need to change the language system wide. Just let me find the command you need. Edit: It was the first google result: sudo languagesetup 1 Link to comment Share on other sites More sharing options...
thecliffhanger Posted January 8, 2017 Author Share Posted January 8, 2017 thank you for your answeri did what you said, i didn't know that command... but it didn't work 100%, look at photos (boot + option key) Link to comment Share on other sites More sharing options...
smolderas Posted January 8, 2017 Share Posted January 8, 2017 Try resetting PRAM and SMC (look for each on apple support site for your model) and try it again. Link to comment Share on other sites More sharing options...
thecliffhanger Posted January 8, 2017 Author Share Posted January 8, 2017 I've done the PRAM reset and SMC reset, same thing, always swedish text in those screens Link to comment Share on other sites More sharing options...
smolderas Posted January 8, 2017 Share Posted January 8, 2017 Hmm. Well if you don't want to downgrade and are brave enough to flash your computer with an unsupported OS, here is how you could remove the OS checking restriction: 1. Download the file from here: (or whatever one you want to flash) 2. Type following in the terminal.app: cd ~/Downloads mkdir efi_tmp && cd efi_tmp xar -xf ../Mac2015002EFIUpdate.pkg 3. Now edit the file `Distribution` with your favourite text editor and remove the lines 649, 650 and 651 (you could search for "10.9.5") and save the file. 4. Now compress the file again with following: xar -cf ../new.pkg * You have now new.pkg in your Downloads. Try with it. Edit: Don't hold me responsible if your machine explodes or won't boot again.

thecliffhanger Posted January 8, 2017 Author Share Posted January 8, 2017 Thanks for the advice You are talking about downgrade, so it could be possible flashing boot rom will resolve the swedish text? Link to comment Share on other sites More sharing options...
smolderas Posted January 8, 2017 Share Posted January 8, 2017 Probably. Maybe try reinstalling the system again from scratch before flashing EFI. Link to comment Share on other sites More sharing options...
LouCioccio Posted January 8, 2017 Share Posted January 8, 2017 You should have restore partition which would be pressing command + R and turn on the computer. Keep the two keys depressed; the Apple logo and line starts to go then release. If you have nothing on the computer thats important do an erase and reinstall like it was first new. You do need a wireless connecting (not sure about wired) as it will access the latest build for re-installing. It will come up about what language so select the one you want. I am thinking about the multiple users may be causing the problem. If you have something important than back up. Hope this helps.

thecliffhanger Posted January 8, 2017 Author Share Posted January 8, 2017 ok, before updating the boot rom i'll try a fresh install with recovery methodthank you, i'll post the answer Link to comment Share on other sites More sharing options...
owbp Posted January 9, 2017 Share Posted January 9, 2017 Probably. Maybe try reinstalling the system again from scratch before flashing EFI. I don't know what efi flashing are you mentioning, but the thing that works 100% is - make installation USB; - while rebooting reset PRAM; - boot into installation USB and you will be asked what language would you like for your OS to be in (you'll have to reinstall OS btw). Not 100% sure, but the same thing should apply using Recovery HD instead of installation USB. P.S. Zapping PRAM is crucial for Mac to ask you to choose a language.

With the way in the first post from in this thread you could set that variable in the PRAM without resetting anything Link to comment Share on other sites More sharing options...
