Question: Mojave - "An error occurred installing macOS" error

I am trying to upgrade my 2018 MacBook Pro 15" from High Sierra to Mojave, but it says "An error occurred installing macOS" at the very end of the installation. I got this MacBook Pro about a month ago. How can I update to Mojave successfully?


I am an iOS app developer and know pretty well about Mac.

Finally managed to install it after numerous SMC resets, etc.

What I did is:

1) In network configuration, disable all "automatic proxy detection", custom DNSes, stop dnsmasq service (local dns)

2) Turn off any VPN software

3) Shutdown and SMC reset

4) Before logging into my account, I've logged into Disk Manager and unlocked it (my disk is encrypted)

5) Logged into main account and finally managed to upgrade.

I also had this problem with MacBook Pro (15-inch, 2018) and Intel Core i9 processor. Have already tried rerunning the install several times. Tried install with disk encryption disabled (was encrypted) - no luck. Reencrypted disk and tried again after resetting SMC which *did* seem to make a difference.

MY EXPERIENCE:


Two days of struggling, tried many things such as

- 2 hours phone call with Apple Support (without result)

- 7 times download 5GB file

- deactivate firewall

- reset PRAM

- reset SMC

- turn on VPN, turn off VPN

- DNS change

- Create new Test User on my mac

- Removing files from library


FINALLY INSTALLED. WHAT I DID?

Just download Mac Os via LAN cable. After download, MacOS Mojave pop up will appear.

Close it

Restart

Go to Application and install it.


Now it works.

Thats the shame Apple Inc. and Apple Guys.

I also have the same problem, on an iMac Pro. Tried both ways to reset the SMC, didn't help. Tried safe mode install, clean admin user install, several downloads, etc, no change in behavior.


My install log seems to contain an error message that I haven't seen in other logs users have posted:


Failed to retrieve linkfile:///Applications/Install%20macOS%20Mojave.app/Contents/SharedSupport/In stallESD.dmg


The file it's looking for: /Applications/Install macOS Mojave.app/Contents/SharedSupport/InstallESD.dmg is in fact present there at that location. Maybe the encoding screwed it up or something. Here's a larger snippet from my install log:
