With an external ssd on apfs my boot time is 5 minutes (4 minutes of that is a black screen before the apple logo), on sierra hfs its 15 seconds.is slow boot problem when trim is enabled still persist on Mojave?
Have you gone to System Preferences and set your startup disk again? Sounds like the EFI loader is trying to find a different disk other than your external SSD.With an external ssd on apfs my boot time is 5 minutes (4 minutes of that is a black screen before the apple logo), on sierra hfs its 15 seconds.
Yeah tried that.Have you gone to System Preferences and set your startup disk again? Sounds like the EFI loader is trying to find a different disk other than your external SSD.
Yeah tried that.
Makes no difference im afraid![]()
Have you tried booting in verbose mode so you can see where its getting stuck?
Seems not. At least no problem on my Mac Pro
Could I ask what SSD you are using? I take it that you were getting a 15-20 second delay in High Sierra, but this went away with Mojave? I upgraded to Mojave recently and found the delay is still there. MP 5,1 with 1TB 850 EVO.
Some people have reported that restoring from a TM backup solved the problem. Do you (or anyone else) know if this is a permanent fix, or it just regresses after a few weeks? I'm happy to try this - I have an internal TM drive, so it wouldn't take that long - but won't bother if it's just a temporary fix.
I've reinstalled the OS - not a clean install but just a reinstall; no help. I have nothing running at Startup and have disabled all my background applications like Creative Cloud but I'm at a loss. I think I have tried every troubleshooting trick in the book. Any help would be appreciated.
I have this issue and it continues on to my use of my Mac. It actually operates very slowly. I have SSD drives from OWC and 32Gb of RAM. One question, how do you handle updates from Apple? Will these, especially the Security Updates, either change for file system or be unable to install because they are looking for APFS?Great post. Thanks Rheid, this worked for me. back on 17 sec's bootup time from pressing the button (from 45-50 sec's). One question though: Convert to APFS is greyed out in disktool. I didn't activate the file vault, is this the reason??
