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!

I was thinking back to earlier in the thread where references to Microsoft were made referring to the documents problem with the October update. Seems like they pulled the update preventing anymore problems and fixed it, plus other problems. It's still not re-released yet, as they are still fixing things they keep finding before re-releasing it. Sometimes it feels like Apple and Microsoft are switching places. In Apple's situation with Mojave, I'm sure if it was bad enough to recall, they would have. As it stands it looks like people with issues are just going to have to wait for the upgrade.

What a mistake to try Mojave! I so regret downloading it onto my MBP. Fortunately I had the forethought to do a Time Machine backup just before kicking off the install process. Whew! However I had all sorts of issues trying to get it into recovery mode. It just kept on rebooting no matter what keys I pressed. After an hour of trying it suddenly allowed me do do an internet recovery into safe mode. I then gratefully plugged in my Time Machine and it is happily chugging away - only 3hrs 20mins to go, it says. Fingers crossed it will boot back again into High Sierra.

You do wonder if anyone does any serious testing at Apple before releasing and hyping up OS upgrades.

I've been a lifelong Apple fan. Bought my first Apple II at Christmas 1978. I even worked for Apple for 10 years both as a reseller and an employee. My feeling is that they have lost sight of their values of quality and innovation. I'm seriously looking at a Microsoft Surface Pro for my next laptop. Gosh, wash my mouth out with soap and water! Has it really come to this?

The infamous file was not on my new 2018 MBP until I had used it for a week and installed a few new apps and done a very abbreviated Migration Assistant run from my 2015 MBP (I stopped Migration Assistant when I realized I couldn't pick and choose from my documents and apps--it just wanted to bring the whole kit and caboodle, which I did not want to do). By that time, the infamous file had shown up.

Wow Ann/iFrog - it sure sounds as though the problem has been pinpointed and if the the Apple engineers haven’t taken note of this thread and our various posts from which to develop a patch, then I would wholeheartedly agree with Ann’s earlier statement as to the likelihood of their “official denial.” Really rather sad when you think about it.

Done, not sure this will have any impact though.

It's kind of sad that there are zero updates from Apple that would provide official acknowledgement, guidlines, timelines etc.

At this point I don't even entertain to try it again, given the issues some faced/are facing and the potential hassle trying to revert back to HS in case things do go south.

For me, Mojave has been a brick since the Beta process, and through the first release. "Brick meaning, very solid with minimal issues." I did not have sysctl.conf, and the ones who did have it, it was migrated through very old time machine backups. This means, once it's gone, it's gone unless a pice of software designed to create custom network settings ,s run, or someone creates it manually. For this thread, that simply means it won't come back, or won't be present unless like those who had it, came through an old back up, and system that hasn't been cleaned for several years.


10.14.1 doesn't show much difference over 10.14, but still feels rock solid. While it doesn't matter to me personally, has anyone here checked the release notes to see if Apple mentions issues people have been having?

Thanks again.


Sorry, I misinterpreted your statement "Both my machines upgraded without a problem.". I assumed you were in the same boat as I, i.e. you couldn't upgrade from HS to Mojave with the initial 10.14 release but succeeded with 10.14.1.


I will hold off until several folks that had issues with 10.14 were successful with 10.14.1 or once Apple officially confirms root cause and resolution.


Since this is my work computer, I am not in a position to take any risks.


Cheers!

That's OK, I completely understand. I brought up the update so people who had issues with the initial release could start looking into the notes about 10.14.1 to see if Apple had provided a statement, or notes regarding fixes that pertain to the particular issues being experienced.


Hopefully Apple will be able to determine what the universal issues are vs the isolated ones specific to the person's setup soon.

I was one f the early posters on this thread. I had been able initially to upgrade my 2.6GZ 15 inch 2018 MacBook Pro and my 2016 MacBook M5 but unable to upgrade my 2.6GZ 2012 15 inch MacBook Pro. I checked for an update. I was able to finally upgrade my 2012 MacBook Pro to 14.1 but I ran into the same old issues trying to upgrade it to 14.1. I tried three times and gave it. Apple needs to get this straight. This is ridiculous.

Well....


MBP 2018, Touch bar, Filevault on


Tried with the latest update (14.1) with the same outcome. Installation proceeds as advertised until I reach the point where it gets stuck. Boot into safe mode, enter my login and password (Mojave background) and I'm in - everything looks peachy except that I'm in Safe mode. Reboot into normal mode, login successful, screen then changes back to Apple logo on black, sits at 80 percent and.....nothing. Just sits there - exactly what happened with 14.0


Sigh, Time Machine restore now in progress - I don't have the luxury of spending hours and hours trying to resolve the issue.


No Mojave for me it seems
