I have several Macbooks with preinstalled SSD with High Sierra. But they are 2013-2014 models and on them never have been installed High Sierra. So I need to update EFI so they will be able to run these SSDs.
Now what I do is install High Sierra from USB drive and after that they are able to run...
This board wont power. No liquide damage. Boards look good and SMC zone perfect.

Because install higt Sierra this way are 30 minutes. If have DMG are 90 seconds. I always do that for other OS X. So I am asking if there is way to create DMG. I know that with USB is possible.
Is there any way to create DMG file for Higt Sierra formated with APFS? I alwasys use DMG for Sierra and Capitan, but cannot create DMG for Higt Sierra apfs.
Very stranged case. This macbook pro comes to me because sometimes when power on the macbook it goes to boot menu and in OS X appears simbols that normaly appears when press ALT+some key.
Keyboard was durty and I thought it is keyboard issue and I repalced the keyboard. Tested and work ok, but...
Ok, now I understand what you mean. Yes in A1502 is preaty easy. Will tell customers only UK is possible.
And what about just keyboard replacment? Same job as A1502? Remove rivets and put same screws?
When you say to damage the butterfly mechanism you mean if I replace only the keys? I want to replace the full keyboard and pull it out removing rivets and put screws instead.Why butterfly mechanism damage?
I just tried with another battery and also slow charching and sometimes stays in 15% so I am not sure it both batteries has the some problem or could be also board problem.
This macbook has faulty battery and I replaced with "new" chines battery. Sometimes it stays at 15% and later goes to 100%. It is bad battery or could be some mosfet also?
