Hi All,
Having a major issues with the 10.12.5 inplace upgrade roll out.
Getting the following message.
Failed to copy file to the install data folder. Failed to copy /Volumes/OS X Base System/Install macOS Sierra.app/Contents/Resources/brtool to /OS X Install Data/brtool: The file “brtool” couldn’t be opened because there is no such file.
Any ideas?
Thanks
Mitch

brtool is no longer included, so you need to grab a copy from an older OS version (El Capitan)
