Problems upgrading to macOS Mojave on MacBook Pro 2018

As macOS Mojave was released today, I thought I would try to upgrade my 15" MacBook Pro 2018 to the latest software. However, when I'm running the installer, after around 2-3 minutes I get an error message that a problem has occurred, with no solution in sight. I have tried to reboot, turn it on and off, updated without internet etc etc, nothing works. This is the error message I'm getting (in Swedish):

It seems that many people have gotten confirmation from Apple that this is an issue with the T2 chip.


I would STRONGLY advice you to stay on whatever OS you are running now, do NOT try to install Mojave or reinstall the OS you are running. Even the people who have gotten it to work are experiencing several bugs with Mojave. If I were you, I would wait until Apple releases a patch for the OS so that it works with the new MBP:s. Thanks for all the insight everyone!

What I’m curious about is whether the people who can’t install Mojave in their 2018 MacBook Pros are the same ones who have been facing the continuous kernel panics which cause the system to crash. Because a friend of mine with the same model as mine has neither faced kernel panic crashes nor experienced any trouble installing Mojave, while mine still crashes after Supplemental Update 2 and no Mojave upgrade.

To solve the Kernel panics, they first have to admit that the crashes exist. Every time I called AppleCare, even on taking my device to Authorised Service, they couldn’t find anything and just reset the MacBook and say that it’s gonna be fine now. Yet facing crashes every couple of days without any apparent pattern. Such a waste of money.

Since neither one of my Macs has a T1, or T2 chip, it's not something currently I have to be concerned about. I would like to see this resolved for those with the issue.


I happened to have very little trouble with my upgrade, and the glitches I had, I was able to repair myself.


There are some here where the upgrade could be failing when they restore their time machine backups. Then there are others that don't seem to have any kind of rational reason people have found currently.

Well, if you've followed Apple for any length of time (meaning from their beginning)The first time they kicked Jobs out, and just about went bankrupt, and fell apart. This time, he's not coming back, and I feel like history might repeat itself.


I still genuinely like their products and use them. But Now, at least to me, hopefully to those who have followed them for a long time. Apple just feels like another name now, not the company they used to be.

The Mojave problem is not limited to 2018 MacBook Pros. I had no problem upgrading my 2.6 GZ model. I had no problem upgrading my 2016 MacBook. However, my 2.6 GZ mid-2012 MacBook Pro has failed to update five times. The most recent failed update attempt was guided a second level Apple tech. As I posted yesterday the first level tech I spoke to yesterday stated that they were having problems with their in-house non-pro iMacs. Apple is aware of the issue but as with recent issues they have failed to make a public statement.
