Mojave install a disaster

I too am having the same problems with a 2013 MBP 500GB SSD. Telling me there is No wifi hardware installed. Slow as molasses on boot and everything else. I have tried everything.

I do get a connection to the apple internet update when I do a restore boot so there is wifi hardware there, just Mojave won't see it. ***..........

If this wasn't ready for prime-time why release it? ***** that this problem exists, but at least I'm not crazy as there is verification here that there is a major problem.

exact the same here: MacBook Pro 15‘ Late 2013 all Apple: no network at all, wifi not installed (works in recovery mode), login almost impossible, the same with the desktop picture, all possible resets and tests done, installed mojave again, trashed network preferences: nothing helped!

Same here, but with iMac (Retina 4K, 21.5-inch Late 2015, 3.1 GHz intel Core i5, 16GB 1867 MHz DDR3. Graphics- Intel Iris Pro Graphics 6200 1536MB. Install froze about ⅔ through, couldn't restart, when it finally did install no internet connection even when Airport Utility showed I was connected, to many other issues to get into, spinning BB when attempting to do anything. I keep a clean system without many non Apple apps. I spent the entire day re-installing HS from Time Machine backup using the Command-Option-R method. One interesting fact was when choosing which backup to use there were 8 Mojave backups already on it, even though Mojave had only been on the iMac for about an hour.

Yup! Same disaster on my iMac 27" 2017. after initial app store download and a reinstall from disk utility - no connectivity at all, slow to no performance at all, random messages that didn't make sense, - A COMPLETE BUST! SHAME ON APPLE. After spending the better part of my day trying with two apple techs and a senior advisor - every one gave up and I ended up erasing HD and reinstalling from Time Machine via My Passport, High Sierra. A disaster is an understatement. Sent an email with trouble ticket # to the senior advisor this morning asking him to call - nothing yet 6 hours later. I suspect that they are inundated with support calls after this catastrophe.

As described before I have EXACTLY the same problem with my late 2015 iMac, am taking then reinstall option first hoping that me interrupting the first install was part of the problem. I have successfuly upgraded to Mojave on my 2016 MacBook.

I have restored to 10.13 with the last backup before I upgraded using Time Machine, and it worked fine. I've been using Time Machine faithfully for 10+ years but this is the first time I have had to use it for a complete restore.

One likely culprit could be a non 64-Bit app, on checking my System Report on System Information I have quite a few, for me none of these were needed.

Now with the confidence that Time Machine actually worked my next step will be to do a clean install and individually reinstall (64-Bit) apps when needed.

exact the same here: MacBook Pro 15‘ Late 2013 all Apple: no network at all, wifi not installed (works in recovery mode), login almost impossible, the same with the desktop picture, all possible resets and tests done, installed mojave again, trashed network preferences: nothing helped!

Bought a new MacBook Pro: Installed Mojave. Transferred the user from last timemachine backup: Can’t login to any user after that. New MacBook Pro dosen’t work: erase and new installation...

Clean install finished and now working as good as expected, having Time Machine in place made it happen extremely well.

I suspect the problem is not with Apple but with a non compliant app or files that we have. To test I will only install my non Apple apps as needed, but I'm guessing the problem won't come back.

Of course I have no backup........... When I try to boot restore to a previous version via the internet (the only way I can connect) there is an error message. The the only option to reinstall is mojave, so I have no options other than to use my macbook as a plant pot base............

Maybe Apple in its infinite (loop) wisdom could put High Sierra back on the restore boot internet to downgrade from this problematic mojave??????

HELP.

Yes that is what I have done and everything is running fine. The report to view is top left About This Mac / System Report / Applications - on the right side it shows if apps are 64-Bit compliant. I now have no 32-Bit apps whereas before I had around 25 some going back many years. These apps will still work for now with Mojave but maybe just one of them has the legacy that impacted our initial installs.

I did some screenshots of my applications folder beforehand plus for the list of my non 64-Bit apps and am only reinstalling what and when I need them.

You know, if the developers and Apple BEFORE releasing this for prime time, simply admitted to the fact that ALL 32-bit apps needed to be purged BEFORE upgrading....that would have been fine. They DIDN’T. I dunno, should they have???

Apple announced on June 5 'macOS Mojave will officially be the last release to support 32-bit apps'. Comments from Apple Support also include 'Yes, you may continue to use 32-bit apps with your Mac today. Using 32-bit software has no adverse effects on your data or your computer.'

My thinking is that I had this issue due to legacy files and settings from older 32-Bit apps that I should have purged beforehand, however which ones and how to find them. Instead I did my first ever clean install, which has worked fine as my Time Machine backups were in place.
