Hello everyone,
Today I tried updating my macbook pro (13 inch, mid 2012) to High Sierra. But the installation failed.
I get the following message.
"An error occurred while verifying firmware"
I tried downloading a fresh copy & retry the installation but still the same error message pops up.
My hard disk is Samsung EVO 850 500GB SSD.
Thanks in advance.
MacBook Pro (13-inch Mid 2012), macOS Sierra (10.12.6), Mid 2012, 16 GB RAM, 500 GB SSD
My hard disk is Samsung EVO 850 500GB SSD.
That's the reason.
You can see for yourself: "An error occurred while verifying firmware". Apple does not develop firmware for devices they do not incorporate in the products they sell, and they do not consider internal a storage user-replaceable option. In other words you're on your own. Samsung "EVO" SSDs are notorious for that problem and others. It will fail soon enough anyway.
Either replace it with a SSD known to work with macOS, or a conventional hard disk drive. If you want to continue using the Samsung SSD, then restore your Mac from a Time Machine backup and do not upgrade.
Installed Mac OS High Sierra , it was an Archive installation from App Store ... so 😢😟
I have a
Yes i do have Samsung 850 EVO SSD 500 GB.
That’s my guess too. Apple is looking for and expecting a stock config. When they don’t find it they brick the install
My SSD is the original shipped with the macbook pro and I can't install High Sierra!
Obviously this has been the absolute worst release of a major update ever. Front page of Ars is mentioning nothing but issues. I’m still waiting for my new SATA cables to come in.
Same error for me too after todays update... 😟
This has been the absolute worst update from Apple. Shame.
Tried the second method - Sierra unavailable from the app store..
Going into Apple on Monday - they can sort it out! Grrrrr
Tried the first method as well - no problem with the disk....
😟
Did you try to repair it in Terminal anyway? It couldn't hurt.
There didnt seem to be an otion to do so..
I don’t know why my last post wasn’t posted.
I’ll wait a while longer
My MBP has now been running for a week with no problems, so whatever Apple replaced has done the trick. Good luck for everyone else.
i have the same error with Mac Book Pro late 2011
Installation Failed! High Sierra.
