I have just upgraded to Mojave through the app store from Seirra. It took for ever at the log in screen and then finally the WIFI is greyed out with a X and when you open a browser there is not connectivity. Late 2017 iMac
I am not running little snitch, it takes for ever to restart too.
Any help would be very much appreciated.
iMac, iOS 12
I solved the problem by doing a clean install of Mojave, and once the installation was finished I used Migration Assistant to migrate my applications, my settings, and my user folder—but NOT the “other files and folders”. Once I restarted, the problem was fixed. This solved both the internet problem and the slow login.
Based on our experience and since you have an efficient Time Machine back-up, I'd suggest erasing the main drive, install Mojave 10.14.1 and migrate your files back across. It's worked for us twice now.
I'm no expert but I noticed that the tech booted it in recovery mode (I think you hold down Command-R) and there was an option to install the operating system. He mentioned that I could have done it myself. You may want to call the helpline and ask em.
After several issues that came up on this 15" MBP, 2.8 GHz Intel Core i7, 16 GB LPDDR3, I found after the installation of 10.14.1 (18B75) that most of the failure points left over from the High Sierra upgrade were resolved. Clearly, the Apple software testing did not take into account the significant changes brought by the new system upgrade and how old configs would conflict. Not all problems are resolved, for example the machine still freezes from sleep (I often do not shut down for weeks at a time), etc.
So far as the problem in this thread, I have found that the IP management and in particular gateway addressing on Mojave is very fragile. High Sierra and Sierra were fragile too but this is more so. If, for example, one has a wifi extender, this must be carefully configured so that it is not running a proxy DHCP server that masks network names by creating a separate subnet to the household router, or that the proxy is correctly configured in Mojave. This is possibly beyond many home users. What I found is that our range extender created a subnet such as 192.168.0.x with an allowable range of 192.168.0.1-199, where the router was 192.168.1.x. Further, the IP gateway on the extender would be addressed as 192.168.0.254 (outside the allowed range of addresses but presumably the onboard OS would resolve that issue). Now most OS's will simply allow the proxy to mask the network name and allow the extender to have its way (for example, Android, iOS, Windows,...), but not Mojave. I should mention that High Sierra did not complain either and another MBP in the house is on High Sierra and works with this.
So, the issue here is that Mojave connects to the network (192.168.0.x), but fails to connect to the Internet because it refuses to accept the bridge to the 192.168.1.1 gateway on the router.
To work around this, I have made the extender have separate extender network names and turned off the onboard DHCP server, and created a fixed IP address on the router that matches the one fixed on the extender. In addition, the time zone on the extender defaulted to a different time zone and for some reason, the router was incorrectly configured too. These can present as issues but when resetting them, the existing problems were not resolved. So, all good there now. But, while the 2.4GHz channel is OK, Mojave frequently fails on the 5GHz channel to either connect or randomly drops the connection. Still working on that problem.
Fixed! I had the same issue. All I did was go to the Date & Time in the System Preferences (which was set to Jan 1, 2018) and set it to the correct date. That's it. Strange, Apple, strange.
Had the exact same issue. Uninstalled little Snitch and rebooted. Internet worked fine. Reinstalled the updated little Snitch. Everything now good.
Yes, even on iPhone the wrong date and time can cause problems connecting to Apple services.
Another possible solution is that some may have a firewall blocking connections. For others having issues you should check your firewall settings and disable any sort of app like Little Snitch if you have such software on your machine. If it works, then that was the problem.
Same issue here: no network, wifi or ethernet. Also slow as molasses in winter.
Tried recovery mode new install which did not fix this. NVRAM reset did not fix it either. Seems the only way to fix it is a clean install and a migration of apps and user data from a Time Machine backup. I will try this next...
I have a mac mini, late 2012 -- 16 Gb memory, SSD startup disk. Wanted to share my experience.
Hands down -- the WORST release of a GA (generally available) OS Apple has ever released and using the in-place upgrade method.
My symptoms are similar on this thread, but mostly include:
The same thing happened to me with a new iMac that I restored from an old one running Sierra. I thought it was an issue with the computer so I exchanged it for a new one. Same thing happened. I was advised to take the computer to an Apple Store, have them wipe it and install Mojave and then re-install apps and data manually, not from Time Machine. As I have docs, pictures, music etc. in iCloud and a small number of apps, I will do that.
Open System Preferences > Network then make sure Wi-Fi is selected on the left.
I just installed Mojave on both my 2013 MacBook Pro & 2014 Mac mini (which I'm writing this reply from now.) Both were upgrades from macOS High Sierra and went smoothly. Each took about an hour (I have only 10 Mbps download speeds here) and they both are running without any issues. 32-bit apps that I knew were problematic were, but I only have a few of them and will either wait for upgrades from the developers or abandon them. I kept a cloned backup of my previous OS and can always run them from there if I need to.
Typically, when I find that an upgrade does not go as planned. I try two things:
If you want to try again (or not) that's up to you. If you do and want assistance along the way we're here to help. However, if you do, I suggest that you start a new post to get the attention that it deserves and not piggyback on the OP's issue as they may be similar but may require a completely different solution to resolve them.
Same issue with 2017 iMac with 1 TB Apple SSD and two WD My Book 4 TB external USB drives. I had to revert to High Sierra, as unuseable. In addition to killing all conenctivity, it also wont mount the external drives. Lots of spinning wheels that take forever. Thx for any help.
I’ve now spent several hours with Apple‘s Support team and have an engineer assigned to the case. Seems to be a decently frequent issue at this point.
In my case:
- WiFi : No hardware detected
- USB Ethernet dongle and Bluetooth tethering not working either
- OS is EXTREMELY slow (my analogy is 486 DX2 80mhz with Turbo off)
Tried multiple reinstalls (not a clean reinstall, but one from the recovery console), NVRAM and SMC reset.
I have a case number, being sent to a store to collect logs and regular calls with the tech team. Hopefully everyone else is opening a ticket to get this escalated...
I had the same issue. No hardware detected for WiFi and Bluetooth, ethernet cable would not work, and OS extremely slow.
I did boot from a bootable Mojave 14.10 flash drive and everything worked fine, so it's not my laptop that is the problem.
I also got a case number, and the engineer suggested I wait until the next version (.1). So, when 14.10.1 came around, I was excited and installed it, but the same issues showed up.
In both cases, I had to revert back using Time Machine. This is really unfortunate that they ahve not fixed this yet.

I had no trouble with Mojave on my 2013 15 inch macbook pro and 2015 12 inch macbook. But my wife’s newer 12 macbook is one that had problem. She has too many password and other setups and uses this with her employment at local schools as sub—they have gone to this complex system of accounts for her to take certification tests annunaly, and schedule work and so on. There is no way on gods green earth I am gong to go back and do a clean install and try to migrate from time machine and then enter passwords and all her setups for this in safari and such.
So unless they can prove to me that Mojave will finally work her machine will sit with High Sierra. It works for her and she does not have financial data and such so missing security updates are not issues like my machines might be. This machine is gona be frozen at this level. Maybe one day I will get her a new one and migrate from time machine for her not today.
She works more on her iPad and iPhone anyway but has to use the mac because the school is using some kind of google/microsoft setups and they won’t work on iOS only MacOS —not sure what it is but anyway but thats about all she does on mac plus put her photos there. So it can sit frozen and work for her she is not a tech person or nerd like me so it could be that way for 10 years (she hates it when I update anway and something breaks LOL)
No internet connectivity after installing Mojave
