You have to patch the firmware on the OWC SSDs for Mojave to work. Apple recognizes that they’re not official hardware and it seems they’re creating problems for those without stock drives. If you still have the original SSD, install Mojave on that and then swap. Here are instructions if the firmware patch does not work!:

This is the firmware patch from OWCs site. Make sure this is for your drive.

Good luck man. I had no idea this was an issue with 3rd party drives. It is a pretty big hassle.

Note that this issue on these particular OWC SSDs is because the controller in question erroneously identifies the SSD to the operating system as a rotational (conventional) hard drive rather than as an SSD.

This is not due to a bug in macOS, macOS is treating the device as the type it is being told by the controller it is.

I tried reinstalling Mojave in disk recovery mode but the problem persisted. I tried resetting the PRAM and SMC. No change.

I called apple support and we tried to go back to High Sierra (or Sierra which came on the iMac) but the computer could not identify the hard drive and disk repair would not work on the drive.

I went to the apple store. Their initial diagnostics could not find the problem. When trying to install High Sierra, it indicated the hard drive was locked. They tried unmounting and mounting the drive to no avail. They next tried wiping the drive but it did not respond.

So they took the computer overnight to do repairs. They said that there was a problem in the disk formatting. They wiped the disk and installed High Sierra. Fortunately I had a Time Machine backup.

I suspect that we may al have this disk "formatting" problem. Idk how it came to be. They said that I should have no problem going to Mojave now that the disk was wiped and reformatted. But I'm going to wait.

Maybe Apple will release info on this "formatting issue" so that people can fix it before they upgrade.

I had to delete and recreate the partition. After I used internet recovery to reinstall Mojave. It helped. WiFi and all external hard drives were recognized, no more latency.

I ran across the same problem and I had to reinstall High Sierra from a backup through Time Machine. If you have backed it up to an external disk, you should be able to do so after you have started with command-r, but go to the install from backup-option then.
I think I will wait until Apple releases an update or if someone smart enough can tell us what the problem is and how to avoid it.
I am on a 2017 iMac, 27 " so the hardware should be good enough, at least.

Just to quickly add to my previous response ... it occurs to me from other peoples posts and the forums over at Objective Development that the internet connection failures may be down to code signature issues with Little Snitch (well at least in my case, as I always have that installed) - there were similar code signature issues with many apps on my previous move to High Sierra.

If you are interested in trying to persist with Mojave in it's current version, then head over to System Preferences>Security & Privacy to see if it lists any software as being blocked or having issues. However, if you really want to flush out all the problems you need to restart in Safe Mode and then look again in Security & Privacy, and (if memory serves me correctly) you need to Cmd+click (if not try Ctrl or Alt/Option click) on the Allow button - this brings up another dialogue box which then lists all the apps with code signature problems (not just one) and you can force them to be accepted from there. Once done, re-boot as normal and see if that helps.

As for me however, I have already reinstalled High Sierra and don't have any more time to waste on a badly finished version of Mojave that Apple should have dealt with before public release - the other issues (dreadful boot times, weird screen resolutions etc) are not down to code signature approval and are other bugs that need fixing. If I had the time to spend doing this, I would have signed up to the Beta Programme like I did in previous versions so that the public release was properly ready - I waited this time for the public release as I need my machine running properly (how ironic). BTW None of the previous Beta versions I ever tested were as bad as this public release of Mojave; not by a long way!

I have the exact same problem with my laptop! same model as yours. I tried 3 re-installs, called apple support 5 times. The issue is not the wifi hardware, because it works perfectly on diagnostics and re installation. It is the software not recognizing the hardware. Kext files are needed to address this issue. Meanwhile I am waiting on a genius bar appointment. If you backed up your files (unfortunately my time machine died on me 😟) you can go back to High Sierra and have it working fine.

I had this exact problem last night when installing Mojave. Found the answer that straightened it right out: just remove /etc/sysctl.conf

Instructions here:

Re: Mojave login UI sluggish & laggy

For those who are getting one or more of the following:
* excruciatingly slow boot, or unable to log in

* sluggish

* Hardware not found errors for wifi

* Touch bar not working

* Bluetooth devices such as keyboard/mouse not working or disconnecting all the time

and have a mac they've had for a while, or transferred from machine to machine using Time machine or migration assistant, then the issue is most likely due to a very old configuration file being migrated across that is no longer used and contains invalid entries for Mojave. (/etc/sysctl.conf)

I've posted a solution here that should hopefully resolve the issue for most of you:

Re: Mojave login UI sluggish & laggy

Call Apple Support, ask to connect with a Senior Advisor. *Might* be related to Kernel Extensions (AirParrot / Little Snitch / etc).

Did see somewhere that apple was changing its file format -- it may be that after the install the files have to be formated to their new way.

I believe apple was doing some testing on iphones for conversion - and then taking it back.

Apple is really bad at letting people know what is going on during an upgrade - very sad.

If you can open Activity - look at disk activity - if it is high - that may mean its doing a conversion.

That is sad. Sure there might be bugs but I would expect a supported computer to be... well, supported. All hardware drivers should have been included in the OS. Perhaps you can create a small partition (if you have free space on the internal SSD) and try to do a clean install. If it still does not work you can boot back into your current OS and just delete the new partition.

BTW, did you check in Activity Monitor for any errors? It may give you hint what may be causing the issues...

Good Luck...

Re: Mojave login UI sluggish & laggy

Seems like user Quirkz might be onto somethin. As I’m travelling at the moment, I haven’t had a chance to check it out yet, but as soon as I’m back home, I’ll give it a try.

I have a late 2015 Macbook pro with 1 Tb SSD drive. Tried early on to update to Mojave and it was a mess. Same characteristics as mentioned. Waited and tried again this past weekend and same issue. Went back to high Sierra that runs flawlessly and very fast.

Do you have enough free space on your drive ? Clean up your hard disk also connect your battery charger before updating.
