    I may do this if I find the time, just to see if I can confirm it before wiping and starting over.

    APFS has lots of benefits when compared to HFS+. Here is a quick rundown of what APFS does: https://developer.apple.com/library...eFormatComparison/VolumeFormatComparison.html.

    The problem is that it’s really made with SSDs in mind and the better the SSD the better your performance will be. Those who have SATA SSDs or PCIe 2.0 will have worse performance compared to those with 3.0.

    I haven’t tried APFS on HDDs since I don’t have a machine with one anymore.

    If any of you use little snitch and/or have littlesnitch.kext in library/extensions, it is known to delay a cold boot to over a minute, 2 minutes in some cases. I had this problem on 2 of my computers and deleting littlesnitch.kext fixed it. Obviously it's a workaround, if you want to keep using little snitch you have to either live with a slower boot or wait for the fix.

    That may be part of my problem then. I hope they update Little Snitch to fix this soon.

    Yes, it's really slow at first boot in the morning.. like minutes. Strangely if I reboot after first boot in the morning it will be fast (like 20 seconds). Disk is internal 840 evo ssd.

    Edit. I have little snitch

    Reboot doesn't seem to have the slow as molasses wait before the Apple Logo shows up. I had to rearrange plugs today. So I turned off the iMac. Turning it back on, it took more than a minute before the Apple Logo showed up and the boot process started. SSD took 20 seconds, but to get to that point you have to wait over a minute. Laughable Apple.

    So last night I reinstalled OS (non formatting) and it didn’t make a difference. The whole process took about 2 hours or more. I await 10.14.1

    8399$ for 2 minutes of boot time on my iMac Pro.
    Well done Apple :(

    My 2017 iMac has actually started to boot faster again. Twice as fast as before but still not as fast as before Mojave. I haven’t changed anything

    I’d also update my grievance; where I’d said at least rebooting isn’t an everyday occurrence, it turns out with Mojave it is. From finder completely locking up, to the trackpad becoming frequently unresponsive, to constant wifi dropouts, this computer has needed daily troubleshooting, and the clunky restart just adds insult to injury.

    Not much you can do but wait to see "IF" Apple fixes it with an update. Makes you think if Apple actually does any real testing with this stuff. I mean seriously, how can this pass quality control? LOL

    Maybe they started macs 1x time and reboot them million times after.
    No cold boot.
    In my company, I am responsible for quality control and assurance.
    Something like that will never happen as long as I work here.

    I've also noticed this - but my delay seems to be in the EFI bootloader.

    I know Apple had EFI issues during the beta period - as at one stage my iMac was unable to boot anything other than Apple's boot loader, but it takes a good minute or so to actually get to the boot loader now.

    I've been having no end of trouble with this bootup stuff, last night did a wipe and reinstall from TM and it was still slow. I was about the throw the towel in, been on so many sites and discussions but thankfully, came here and discovered the Little Snitch thing, yep there was a .kext there and a few other things that didn't need to be since they hadn't been used in donkey's years. Removed those and now my bootup is down to just 16 seconds. Relief!! Thank you @mattydaboy!

    What kexts? The Little Snitch latest nightly doesn’t solve this so you will get the slow boot again at cold start.

    The .kext was in system/library/extensions, I deleted that and now my bootup is fast! Good idea to clear out any LaunchAgents that you have that may no longer be used or where their sibling files are absent. Presumably, that's what the LittleSnitch kext was doing, spending bootup resources searching for the other files to run it and when they aren't there it just stalls everything.

    You still didn’t tell what specific kext you removed. I don’t have any unused launch agents.

    It's LittleSnitch.kext, you replied to matty so I thought you'd read his post mentioning it. If you look in Extensions it should be glaringly obvious which one it is which leads me to think maybe it's not present for you and the nightly builds don't use it. I had been using a very old version of LS from years ago so they must have moved on from kexts now

    Older versions of LS don’t work with Mojave so what version are you using ? I’ll check if I have this kext but I don’t think so.

    I would expect so! I hadn't used it in a very, very long time. It would have been back in Yosemite/El Capitan years that I used it last, just hadn't caused a problem oddly enough until Mojave!

    Ok but that kext or launch agents are not the problem. You will notice very slow boot in a cold start (i.e. in the morning)

    —- I can confirm there is no trace of the kext and no unused launchagents . The only launcher is for Dropbox and it’s working.

    On my MacBook Pro (15-inch, Late 2016), I uninstalled Little Snitch plus nearly every launch agent/daemon and extensions excepting Apple 1st party agents. Made no perceptible difference in the boot-up time; Mojave is still slow to boot and even slow to shut down.

    I have decided to wait for 10.14.2 before reinstalling. I hope it will be out soon
