Slow boot

Themis said:
The quicker boot time remains as in Sierra. Maybe there was some glitch and after some boots the system automatically ignores it to achieve normal boot times.

My slow boot issue continues. The culprit seems to be trim. When i enable trim boot is slow (hangs for a bit at around 75% progress - then continues).
Disabling trim gets me back to quick boot times. See the discussion here:

My boot times remain fast as with Sierra. My problem is wake up from sleep. Most of the times it take ages to wake and there are times that it wakes instantly even faster than Sierra.??????

I have a stock apple ssd, so disabling trim for me is a no go

Agreed. I'm by no means suggesting disabling trim, even if it's an option. But I submitted a bug report to apple suggesting they look at high sierra and how it behaves with and without trim enabled, since that seems to be a key factor in the slow boot times.

I think we're seeing what is essentially still a beta OS. Hopefully by 10.13.2 or so all these issues will be ironed out.
 
So, how many are getting the slow boot with clean installs?

I now have clean installs on all 5 of my machines.

2017 Core i5 7600 iMac (APFS SSD) - 17 seconds
2017 Core m3 MacBook (APFS SSD) - About the same as above. Can't remember exactly but definitely less than 20 s.
2010 Core i7 870 iMac (APFS HD) - 50 seconds. First reboot didn't complete even after 20 mins. Must have been doing something.
2009 Core 2 Duo 2.26 MacBook Pro (HFS+ SSD) - About 23-25 seconds or so
2008 Core 2 Duo 2.0 MacBook (HFS+ slow SSD) - About the same as above

Note that the 2010 iMac with HD was uber slow at the beginning but after repeated reboots it was fine.

Also, make sure all peripherals (esp. drives) are unplugged when testing, and make sure your boot drive is selected in the System Preferences as the Startup Disk.

I had this problem with my High Sierra 2017 iMac upgraded from Sierra. A clean install fixed this. Note though I had the same issue in Sierra, so it wasn't an issue specific to High Sierra in my case.

Just a thought, but you might try the command to turn off "hibernate mode" if it's enabled:

sudo pmset -a hibernatemode 0

The last number determines how the computer sleeps:
0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).
7 - This is the same as mode 3, but it’s for those using secure virtual memory.

To see which mode you're currently in:
pmset -g

NOTE: these are from my archives. I'm not sure if they're still relevant in LoSierra or in HiSierra...

I did a wipe, a clean install, then used migration assistant to bring all my stuff back in. The os ain't worth much if it only boots fast with nothing installed on it. Again, in Sierra with the exact same hardware and software the boot time for me was about 25 seconds. With High Sierra, it's double that (52 secs).

And again, the excessive boot time is the result of the progress bar pausing at about 75 percent for more than 20 seconds before proceeding. This symptom completely goes away if I disable trim.

This Apple developer thread discusses the issue exactly:

I had the same experience with my MacBook Pro mid 2012 and my Samsung 840 evo 1tb.

After two days of trying, I found out that disabling the trim command by "sudo trimforce disable" fixes my bug permanently and reproducibly.

in Sierra the default is 3
 
I can also confirm that even with Beta 10.13.1 (17B25c) the problem persists. I disabled TRIM and it booted twice as fast, just like it did in Sierra. And system information does say TRIM Support: NO.

I'm really disappointed in how bad state this system was released. Boot problems, artifacts in desktop picture, blurry PDFs, etc. I miss the old days when it took 3-4 years to have a new system but it always came very polished. Updating the OS every year is too much of a hassle.

EDIT: Just filled in another bug report.

10000% agree. There is no point to "upgrade" the OS every single year, and end up only able to give out a buggy OS every single year.

I don't know how many users care about the new emoji more than a stable OS. For me, the functions of the current OS is fine. I don't need any new fancy stuff from day to day, but I really want a stable and operationally bug free OS.

I still miss 10.6.8. However, I must upgrade to latest OS, otherwise, my GPU won't work, and the notes etc can't sync with my iPhone. I appreciate the iCloud convenience, and I value that a lot. However, in terms of function, it's quite enough now. No point to keep pushing more iCloud functions (which has diminish return in value), but sacrifice stability.

there is a software update ant it's related to apfs.
has someone installed it? did it fix something?
Click to expand...

I installed that almost right after it was released.

So far, the feeling is good. Don’t know if it does anything to APFS. But clearly the whole system is smoother. Even my CPU (all cores all threads) under 100% load, the system UI and Safari still as smooth as during idle.

Also, the strange occasional Finder freeze (only happen under prolong high CPU loading) seems gone.

And no KP so far.

They specifically advertised one of the advantages of high sierra and apfs was faster boot times, so thats what makes all this doubly disappointing.

exactly, i'm not going back because of file cloning and snapshots, but those "faster boot times" doesn't seems so fast right now. I've installed the update, and it still slow, idk what to do or believe at this point
 
I wonder since most are complaining after an install, does indexing have anything to do with it? Has anyone’s times improved over time? Or are your machines consistently slow days later?
 
same here slow boot times and slow copying of large files even after update samsung evo 850 ssd

No nothing to do with indexing. Boot is still much slower (even after the last HS "supplemental update"), and some apps take more time to launch (QT or Pro Tools in my case), and intermittent verifying of video files. That aside, HS seems solid so far, so I hope Apple will fix these issues soon.

I'm facing the same issue on my MBP 13" 2013 + 3rd part SSD so I tried disabling trimforce and was quite better, then I tried re-enabling it and the issue got back. On 5th Oct (aka day before yesterday) I updated the OS but still with no bug fix, my current fix is still disabling trimforce
