Problems upgrading to macOS Mojave on MacBook Pro 2018

Hi all,

After more than 25 downloads it finally worked for me. Below step by step guide that I followed and its hopefully easy to follow for non technical people.

1. Disable Wi-Fi during the complete installation
   1. System Preferences -> Network
   2. Select Wi-Fi and click "Turn Wi-Fi off"
2. Plug in USB LAN Port to connect to your router (you need a special adapter to support USB-C)
3. I had the "AdBlocker Pro" software installed which uses Proxies (you need to clear the proxies)
   1. To disable the Proxies go to System Preferences -> Network -> USB 10/100 ....
   2. Select Advanced -> Proxies
   3. Un-click all protocols
   4. Click Ok and then Apply
   5. Close network
4. In Finder: Open Applications and delete "Install macOS Mojave" and other versions as well
5. Restart your MBP - it is essential that you reboot AFTER you have removed the Proxies - Proxies are still enabled even if you have done as described above until you have done the reboot.
6. In App Store search for "MacOS Mojave" and download
7. Install Mojave (30 min or more)
8. When done re-enable Wi-FI and the proxies you need

I hope it works for you - it did for me. It is all about sequence

Hey people. I might have a solution for ya. I've been really struggling with the so called error 602 (readed out of the installer log) when the installer stopped at around the end before restarting preventing the computer to reboot and install.

Not sure if it has anything to with this, but the secure boot is on low security for me (set it in recovery OS) and after doing everything I could find anywhere (even a clean install), the solution turned out to be the SMC reset but make sure you follow these steps on the 2018 MacBook Pro with the mentioned T2 chips:

(check it in the System Report/Controller)

1. Choose Apple menu > Shut Down.
2. After your Mac shuts down, press and hold the right Shift key, the left Option key, and the left Control key for 7 seconds. Then keep holding those keys while you press and hold the power button for another 7 seconds.
3. Release all three keys and the power button, then wait a few seconds.
4. Press the power button again to turn on your Mac.

After resetting the SMC with these steps the installer managed to pass through where it always stopped. The auto proxy was turned off for me by default, it could never be a problem but everybody was assuming that.

I hope this solves it for more people!

I am having the same problem on a 13" 2018 MacBook pro. I downloaded the installer, and then the install fails after a few minutes with the message "An error occurred installing macOS". I haven't been able to find any more detail about why it's failing.

Hello,

I've got a MacBook Pro 2018 and I'm having the exact same problem. I tried deleting the original download and downloading it again, but in vain.

I've spoken to Apple Care and they are investigating and will get back to me later, so let's see.

I haven't tried resetting the SMC yet, but I might give it a shot.

I have a MacBook Pro 2017 and the install freezes after almost completing. I have tried all the suggested resets. Have tried a clean installs with same results. Tried without using my Time Machine backup as if a new computer and Mojave installed but when I tried to migrate it all went for crap after 3 hours of download to just freeze on boot up.This is the worst piece of software produced by Apple. I have always upgraded without issues an 6 Macs over the years and this is absolute crap software.

Looks like it’s a problem with the new MacBook Pro. I had this problem last night, I tried installing and redownloadig the installer multiple times and none of it worked. Contacted Apple support and they had nothing too. Has to do something with the new T2 chip.

2018 27” iMac - upgrade from High Sierra to Mojave - a complete bust! No internet connection, no bluetooth, completely inoperable computer, no My Passport connectivity....on phone with Apple tech support now reinstalling and trying again. Have owne Mac’s for over 30 years - never have seen anything even close to this mess.

I was able to upgrade my 2016 MacBook and my 2018 15 inch MacBook Pro to Mojave but I had four failed attempts to upgrade my mid 2012, 15 inch, MacBook Pro. IK downloaded the installer file from the Apple Store banner. I stayed up most of last night trying to get that installer to work. After a few minutes the installer could not find the the hard drive. Even in disk utility I could not find it. I had to remove the installer and reselect the main hard drive in Preferences in High Sierra to get it to work without using the reboot with the options key.

There is definitely something wrong with the installer that slipped through beta testing with respect to the latest MacBook Pro (mine is about a month old).

In retrospect, seeing the issues others have reported, I'm glad the installer failed. 😉

I left my iMac overnight to do the install, next morning iMac is waiting for me to LogIn. Mouse won't move, spinning beachball every couple of seconds. Plug in an old fashioned USB mouse, pointer moves. Try to key in password, keystrokes only register every couple of seconds. Rebooted, cleared the NVR, no change. Only option, restore from a TimeMachine Backup to High Sierra. Good effort Mr Cook, wouldn't have happened in Steves day.

Mohave Upgrade - WARNING!!! Not ready for prime time on my iMac - OS Version 10.13.6, Retina 5K, 27-inch, 2017, Processor 3.4 GHz Intel Core i5, Memory 8GB 2400 MHz DDR4. Following first download from the App Store, complete corruption losing all connectivity - bluetooth, internet, My Passport/Time Machine - multiple other issues essentially rendering the computer inoperable. Managed to retry installation of OS through Command R/Disk Utility - Second try resulted in same issues. Senior tech advisor from Apple said he would call back in 20 minutes following installation - didn’t hear back for several hours later - after I had already decided to Command R a second time and erasing my HD and reinstalling High Sierra from Time Machine backup. If you haven’t upgraded...DON’T until Apple works out all of these issues. It’s truly disappointing that they would decide to release this —- and shame on me for being so quick to do so!

This is really a poor performance from Apple. I’m still unable to upgrade despite trying everything (SMC reset, auto-proxy deactivation, downloaded and deleted the installer so many times, etc). Still nothing works ... this is a real disappointed .... I’ve booked an appointment with a genius ... I doubt it will result in anything apart from wasting more time and effort ... I thought Apple was about the harmony between software and hardware?! Ah well ... Very poor ....

I would suggest anyone who is doing the install of new os.

a) do a time machine back BEFORE doing so.

b) run onyX maintenance script, Its free to download and use.

That will ensure you have a backup if it goes pear shape & that the os is functioning correctly first.

I found it even more troubling that the two Apple techs I spoke with plus the Senior Advisor (twice), none of them had a clue as to what was taking place but all expressed their belief that it was unique to my iMac and a few others! “Best defense is a good offense.” This is beyond “poor performance.” It borders on complete incompetence.

Finding it strange that this issue has not created more of a interest. Doing a Google search does not produce any results related to Mojave Install issues other than for the beta version.

I feel I am being left in the dark here.

Thanks Apple
