High Sierra to Mojave upgrade installs not working
mid-2015 Retina 15" MBP macOS 10.13.3 High Sierra
- attempting macOS upgrade to Mojave 14.6.01 (Installer downloaded from App Store)
When running < Install macOS Mojave > Installer from Applications folder -
it times out, repeatedly for last 3 days, stating - "Recovery server could not be contacted"
When running Terminal to build USB "Bootable Installer/ Mojave"
- sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
(replacing 'MyVolume' with "name of" fresh GUIDpartition/journaled USB 32GB)
as per https://support.apple.com/kb/HT201372) -
Terminal repeatedly concludes with -
" To use this tool, you must download the macOS installer application on a Mac with 10.12.5 or later, or El Capitan 10.11.6. For more information, please see the following: https://support.apple.com/kb/HT201372. "
referring back to the same ApplePage for creating bootable USB Installer -
while, as stated above, the Mojave 14.6.01 Installer is still sitting in the Applications folder.
Thank you for any assistance with this!
