Problems upgrading to macOS Mojave on MacBook Pro 2018

Hey guys, just wanted to provide some feedback on my experience. While I didn't have any issues, maybe providing my model information would help if anything just to provide information.

I have a late 2013, 13" MBP which I did the beta testing process on, and that hasn't had any issues. That computer still has the last beta on it, so it hasn't been moved to final release yet.

My main computer is a 27" late 2015 iMac specs are as follows:

3.3ghz core i5, SkyLake CPU quad core.

AMD Radeon R9-M395 (2 GB VRAM) GPU

2TB Fusion drive

32 GB RAM (Crucial upgrade kits x2 16 kits from amazon)

With this said, I did also want to mention that my fusion drive converted to APFS upon upgrade from HFS+ with zero issues.

The MBP specs are:

2.4ghz core i5 Haswell CPU

Intel Iris GPU

8 GB RAM

256 GB SSD.

In my case I started the iMac on release day left it, came back about 20 to 30 minutes later, and it was ready to go.

I'll also add that almost ALL my apps were upgraded prior to Mojave release, or right after installed.

I only had about 1 issue, and that was with HomeBrew, and that was more likely my fault for not upgrading Xcode and command line tools before using homebrew after the upgrade. That is fixed now. Since then I've been running Mojave since release date, without issues. In fact, some things feel better then high sierra did.

With no disrespect to the other readers on this thread, I was personally surprised to see all the Mojave upgrade issues popup. I thought it was a pretty good beta time, and not having the issues I usually got on past upgrades from Apple, I was finally thinking Apple did something right, and people would actually enjoy upgrading this time without issues.

Anyway, hope this information proves useful to someone here, and those still having issues, hope they get resolved soon.

Well I’ve tried again, this time using a fresh download and install from USB stick. No other devices plugged in apart from an Ethernet cable. Same result, seems to be something relating to Bluetooth? It’s looking for my mouse (by name) but not finding it. Spinning pizza. Keystrokes taking about 5 seconds to appear.. now restoring back from TM ... again!

ATTN: APPLE DEVELOPERS

Pattern - Download of Mohave OS results in:

No connectivity including wi-fi, bluetooth

Loss of or sporadic connection to wireless mouse and keyboard

Keystrokes delayed by several seconds

Random pop-up messages from installed apps

Loss of Mohave OS screen and return to previous installed OS screen

Sporadic and flickering display

Significant and random delays in loading apps

Restoration to previous OS from back-ups - computers return to normal operation

Hey!

Just out of curiosity -- what OS are you on right now?

1. are you on any OS lower than macOS High Sierra? If so, upgrade to High Sierra First.

2. Are you on any Beta macOS?

3. How much hard disk space is left?

T2 chip is the problem, I have just spoken to an engineer from Apple who confirmed my suspicions. They are now aware of the issue, I am just going to wait until a fix is issued. They have asked me to run some tests which I will do tomorrow. Like most I have tried everything on this forum, however I should have realised earlier that if you cannot install a fresh copy of High Sierra from recovery mode then you are not going to have much luck with Mojave. It had to be something to do with an MBP 2018. Wasted a couple of days..oh well.

Seriously Apple! Less than a month of buying my MacBook Pro 13 2018 and number of crashes is making me pull my hair out. I was hoping that the crashes will be fixed in Mojave, but I cannot even install it now. I spend half my life's saving on this because I needed it for my career and now it only seems like I made a bad investment. No help from Apple Care or even the Authorised Service Center. Well done, Apple, not only did you disappoint me extremely, I even lost a lot of money.

The mere fact that one of Apple’s so-called “senior advisors” provided me with his email address and invited me to contact him using my trouble ticket # - which I have tried, and I have heard nothing back - strongly suggests that they have no clue as to the cause of these problems. Hopefully, the “engineers/developers” are working on this.

I wanted to post an update, I found a problem with the new App Store yesterday, and while it's not guaranteed to affect everyone, here is what happened, and what I did to fix it.

I'm posting this here because the problem seems to have come from upgrading, so if people here do manage to upgrade, watch out for this issue.

The Problem

App Store doesn't see any updates, even though they are available.

Solution:

Use an uninstall app such as AppCleaner, App Delete, or iTrash

Drag the App Store icon to the uninstaller app Icon, or select App Store with the uninstall app's search function.

Let the uninstaller app find and display the list of all associated files.

From that list, uncheck App Store

uncheck /Library/Application Support/AppStore

everything else is either user specific settings, or caches, so they can be deleted.

After deleting, empty trash, and reboot the Mac.

On restart, open the App Store, and log back in, and you should be good to go.

Hope this helps someone, and it's the only major issue I have encountered since the upgrade. Though in the past, it seems like damaged App Store cache and settings can happen from time to time.

Hopefully this will save someone time from a clean install just by resetting the problem apps.

Let me remind you that this issue is not a T2 issue alone. I am having the same issues on MBP model prior T2 a late 2016. 4 installs tried and all sorts of configurations as described in earlier posts.

I agree. The T2 issue is but one of what appears to be multiple issues on MPB’s, iMac’s, (with and without the T2 chip) etc. If Apple’s eventual fix (es) results in purging all 32-bit apps, then they shall have played a fast one on all of us.

Hi, is there an official response anywhere? how would I know if apple is aware of this. Just want to understand how someone can follow this and compare if your brand-new 7 grand laptop is part of this issue 🙂

Thanks for the quick reply folks

...or a 3 month old 27” iMac (not as expensive richsark as yours) but the same problems. I have seen no ”official” or for that matter “unofficial” response from Apple - thus we may assume, it IS what it IS - a major FLOP! The BEST advice from the various posters hereon is WAIT, WAIT, WAIT - and DO NOT ATTEMPT THE MOHAVE UPGRADE until these problems have been resolved. Day ago, I suggested that Apple pull the Mohave app so as to not inconvenience so many loyal Apple users! They obviously have chosen not to do so.

ok, I get it... Ill standby. I hope its soon. also... I wasn't trying to put on a price tag on our stuff... just that its odd we are having this issue plus with that throttle cpu issue out of the gate.

I hope we get an update soon.

Thanks team !

No, no I wasn’t at all suggesting the price tag came into play and didn’t infer as such - just that the problem(s) seemed to span a wide range of computers irrespective of model. It’s disappointing across the spectrum. I agree - hopefully an acknowlegement and an update soon.

Trust me Robin...my new 2017 iMac (latest model available in June 2018) purchased just this past June - the Mohave upgrade was a total disaster. Respectfully, I don’t think it’s helpful to delineate which models yet are effected since many across the board have been mentioned in this post.
