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!

dmauch, that was part of my point yesterday, and I apologize if you confused my comment along with Robin's.


I was mainly trying to say two things as nicely as possible without stepping on toes.


1. Was, ever since Steve passed away, I find Apple hard to take serious sometimes, with some of what they say and come up with now.

2. With all the bad information online, and the internet trolls, it's also hard to know who to take seriously there as well.

Wasn't intentionally trying to minimize anyone's problems at all. Just speaking from the experiences I've had personally and have talked to people I've known for a while, and of course my mother's experience.


When it comes to customer service, whenever I've had to communicate with Apple, I've had good experiences.

FYI, I do have my A+ certification, and have had some experience in computer repair. I just never got Apple certified because I don't know enough Mac users to make the cost worth it. The main reason I still use Apple products though is:

A: they still offer the best accessibility for special needs (though other platforms are much better now)

B: I'm so used to the software, and investing in a new platform beyond hardware, is not something I'm looking forward to (just yet.)

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.

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.

According to the feeds I follow, today Apple Released the second beta of 10.14.1. I've been keeping an eye on this thread, and watching the articles from MacRumors, and nothing has come up yet regarding all the issues people are having on varying degrees with the upgrade.


Either no one from MacRumors has had issues, or Apple hasn't said anything yet.

I once and a while get stuff from iMoore, and I watch MacBreak once and a while, but haven't heard anything more then what people are saying here. So, so far, no new sources have crossed my path yet. I am keeping my eyes open though.
