Mojave install a disaster

My upgrade to Mojave has been an mitigated disaster. First I could not even get past the 90% or so marker (on the little bar) after the first installation. After waiting for what I thought as an inordinate amount of time I did a hard restart. After restart the screen immediately jumped to where it left off. So I did a hard rest and went into recovery mode. selected reinstall Mojave. Did the same thing; stopped at the 90% mark. I finally let it run over night. This was yesterday. This morning I when I looked at the screen it was at the Login screen. I tried logging in but it was so slow and painful. After every letter I typed the beachball would spin. Another weird thing was the account picture was still in its original place (it happened to be on the far left) but would “inch” closer to being over the text box with every letter I typed.


I was finally able to log in. The desktop loaded by slowly. I tried selecting an applicat to get a window. Nothing. Finally I was able to get the computer to shutdown.


After looking for some help I found a message with a link to a YouTube video. There were four recommendations: 1) Hard restart, 2) boot into safe mode, 3) zap the PRAM, 4) Recovery mode. I tried all three nothing really worked. Maybe a slight, and I mean slight, increase in speed. Now I am upgrading a MacPro with 2 quad-core processors. And I am upgrading fron 10.13.X. Finally tried Recoveray mode again.


When I finally get to the desktop the strangest thing is I have no communications. Under the grayed out Wi-Fi icon in the menu bar it says “No WiFi hardware installed.” The Network pane in Systems Preferences shows nothing connected to the two Ethernet ports. I am writing this on my IPad, so I know the house network works.


I am am at my wits end. I made a backup of the drive BEFORE I started the upgrade but I have no way of “slicking” the SSD drive so I can do a clean install.


i really could use some help!

SUCCESS! In fact the following did work and enabled me to sucessfully upgrade from High Sierra to Mojave resolving all issues. IMPORTANT: Make sure your spacing is correct when typing ls -l /etc/sysctl.conf into the Terminal.


A. If you can log in (even if slow), or you're still on High Sierra, and have not yet upgraded, follow these instructions:


1. Start the terminal app from Applications/Utilities


2. Check if the file exists, by typing

ls -l /etc/sysctl.conf


If this returns a result like the following, then the file exists. If it does not, then your issues are caused by something else

-rw-r--r-- 1 root wheel 136 24 Nov 2013 /etc/sysctl.conf


3. Simply rename the file by typing in: sudo mv /etc/sysctl.conf /etc/sysctl.conf.bak

(You’ll be prompted for your password)


4. Restart your computer, and you should be all set, or if you've rolled back to High Sierra, you should be good to attempt the upgrade again.

I believe Mojave still supports 32 bit apps. The next release won’t. So there should be no issues.


Furthermore in previous releases older apps didn’t make the system crash. You just couldn’t run them and were given an error.


A few people on other thread had the same issues doing a clean install. Personally I have so many files I’d rather not go through that.


I may just wait for the inevitable update to Mojave and hope it’s worked out these initial bugs.

I am shocked it's nowhere either. I googled the first day and found nothing. I ended up finding out here I wasn't alone with this.


A little surprised this happened too. I've never had a problem upgrading before that I can recall.


I am at this point just checking constantly for updates to everything daily, with the hopes that and maybe the next Mojave release will install . . .


I have too much in the way of software and plugins to go through the headache of a clean install and reinstalling everything right now. By time I can find the time to do that, I'm sure the next release will be out anyways!

Thank you for having these discussions with Apple. I never did get in to see the Genius Bar; I restored back to High Sierra from Time Machine instead and the computer is now working flawlessly. I'm leery of trying any Mojave installations until I see an update to the "point one" version. I am really astounded at how badly this has gone.

With respect to supported graphics, my mid-2012 Macbook Pro has the Intel HD Graphics 4000. In the system info it says "Metal: Supported, feature set macOS GPUFamily1 v4" - and this machine took the upgrade to Mojave just fine. Mind you, I have also upgraded to a 500GB SSD and jumped from 4 to 16GB of RAM. Hope that's helpful.

My friend spent three days with Apple Support on the phone, a very helpful man in Portugal sorted out the problem, and his Mac works fine now. I will not upgrade myself yet -

Number of Processors: 1


Total Number of Cores: 2

I bought it in 2013


Although it will take Mojave I think I'll wait

“been on Safari and used Mail...and done a very brief Migration Assistant...Indeed Ann, what and from where did the sysctrl file get imported. I sure hope the Apple engineers are reading these threads/posts. It’s beginning to sound that a Mojave patch shouldn’t be ”rocket science.” Many thanks for the valuable input!

I have had all the above mentioned disastrous problems "upgrading to mojave" and have spent countless hours on the phone with apple support - escalated up to 2 senior advisors, 1 of whom will be calling me back today in a couple hours only to be disappointed that my 3rd install of this awful mojave has not worked yet again. So, when I read this thread and try to look at my 32 vs 64 bit apps (I'm not that computer savvy but am really trying to understand as much as I can), I followed your instructions above - when i went to About This Mac / System Report / Applications....when I hit Applications, i got an error that stated "The plug-in did not respond quickly enough while gathering this information. I can't even decipher which applications may be giving me an issue. Do you have any suggestions on where to go from here? I want to go back to High Sierra and I do have an external hard drive back up that I can restore from. I would just need detailed instructions on how to go about doing that. Is someone willing to provide those for me? Please can somebody help me as I am growing tired of rebooting and waiting tirelessly for the same result....apple is not helping me! Shame on them for releasing this before it's time!!!!! Thank you in advance for anyone willing to lend a hand....
