    If you used DiskmakerX to install Mojave previosly after some restart Macs with T2 chip will go in bootloop.
    Install Moave again, I hope you got TimeMachine backup, with Internet option.

    I'm having the same issue on the Mac Mini 2018 after installing 10.14.4
    Reinstalling did nothing, and the only work around is to enter recovery mode each time it happens, visiting the 'startup utility', and then rebooting.

    Is there any way to downgrade to 10.14.3 ? or better still to solve the issue?

    Do you got any devices attached to your Mac?
    You can restore previous version with a TimeMachine backup.

    I've got no devices connected except for the keyboard mouse and screen via the DP to TypeC cable.
    Sadly, i got no TimeMachine backup, i just would like to install a fresh image...

    From the kernel panic message, the cause seems to be related to my 10G ethernet card somehow.

    Did you tried an Internet install? (cmd, option, R) key at reboot.

    Yes, i've disabled all security options in the recovery mode.
    I don't see a spinning globe, but the network utility shows two active network connections (wifi and wired)

    OK, now i've done the "Internet recovery" option properly with the globe, and i'm sad to report that the problem is still here.

    But i've noticed that it is limited to a 'cold' boot, if i do the 'reboot' option from the recovery option, macos loads just fine.

    It is clearly a bug with the 10.14.4 release. Now the question remains, can i somehow revert to 10.14.3 ?

    Or, my mac is destined to be remained like this until somewhere in the future Apple will fix this bug? (probably only on the 10G NIC option on the mac mini 2018)

    I've never used DiskmakerX and I am having this problem as well on my iMac Pro.

    Same here. Can't re-install from recovery or Internet recovery. It complains about a damaged install or missing installer resources.

    I'm going to look for a non-reinstall option for now.

    Do you got some devices in USB or Thunderbolt ports?
    I got a mechanical hard disk and a monitor connected with a cable thunderbolt/displayport.

    I have the internal SSD, a USB 3.1 Samsung T5 SSD, and a USB 3.0 SATA drive (timemachine). I have tried booting with all of the externals disconnected.

    I reinstalled Mojave from the App Store (didn't wipe my install, just installed over the existing) and the install goes into a loop in the same way.

    Verbose mode shows that there's a panic and it reboots, but it's unclear what it is (really unclear because even though I video it, the video is hard to read due to ghosting of the text as it scrolls by quickly).

    Same for me. I've tried re-installing twice with recovery mode and twice with Internet recovery mode.

    Despite my lack of desire to do so, I updated to the 10.14.15 Beta 1 and that seems to fix it. Hope it doesn't break much else!

    I'm on the beta train (10.14.5 18F108f at this point) since this first occurred. I've forgotten that I'm on the beta, it's been so problem-free.

    If you don't want to go to the beta, which is totally understandable, then expect the fix when 10.14.5 GA is released.

    Oh, Update 3 is available. I'll try that and if I'm not back in an hour or less, that means something went wrong (LOL).

    Still good at public beta 3 a.k.a. macOS 10.14.5 (18F118d)

    i'm still with the issue on 10.14.4, with my workaround (recovery first, then warm reboot). I figured downgrading without timemachine is too much of a hassle, and since @bplein reported it should be fixed on 10.14.5, i'll try to wait it out.

    Since my Mac mini isn't my primary machine, i guess this is an acceptable for now :(

    Quick update, I've submitted a bug report to Apple, and the just closed my bug report as a Duplicate (original bug id: 46342150).

    I guess they are well aware of the problem, and the fix is indeed most likely coming in 10.14.5....

    10.14.5 seems to include the fix that the beta had. All good here.
