Hi
I have a problem with apfs on my ssd external that I use for boot.
With High Sierra and both Mojave, booting from external ssd apfs is long (2 or 3 minutes)
Using HFS Journaled in High Sierra the boot is about 20"... But with Mojave it isn't possible using HFS.
So, the problem is APFS with external SSD
Any solutions?
Thanks

The only fix I found is a thunderbolt enclosure for the SSD. Got mine today and boot time is normal, now.
The problem occurs before the Apple logo shows up. It took up to 4 minutes before the logo shows. After that boot time was about 30-40 seconds. With the thunderbolt enclosure it is between 10 to 30 seconds until Apple logo and another 10 to 20 seconds boot time. There have to be some changes with the USB boot loader, because it takes the same amount of time, if I press the ALT key while powering up --- up to 4 minutes with the USB SSD enclosure and a few seconds with the thunderbolt enclosure. Apple, it's time for a fix! I had to spend 106 Euros for a simple enclosure for my System SSD which worked just fine before Mojave!
Delock 2.5" Enclosure SATA HDD>Thunderbolt external enclosure
they're crazy expensive for an enclosure
Is it thunderbolt 2 or 3?
I have the same issue. At first I thought I did something wrong but now I see I'm not alone.
Internal drive is APFS, too --> Mojave
It shows "yes". Otherwise I could not have used the TRIM command in Terminal, too.
it shows NO
so, now you have internal Hd APFS and external SSD (boot) APFS, and you don't have any problems boosting Mojave?
Interesting!
Can you write the model of the ssd thunderbolt drive? Thanks!
You're right, issue not specific to T5 same issue with a SSD Crucial CT500MX in USB enclosure
Any chance to get a fix from Apple ?
In my case the problem disappears in the last Mojave update (10.14.3).
Regards.
Can anyone else confirm this? I don't have access to the external SSD anymore but I'm curious if the issue has been resolved.
Not fixed for me. But I don’t boot off my external apfs volume. So I wonder if the delay is the firmware trying to decide if the volume is bootable or not.
Will just a USB3 to Thunderbolt adapter solve the issue I wonder.
Installed an external ssd yesterday. Worked like a charm. Looks like the issue has been fixed in 10.14.3
