Slow boot

I didn’t understand it neither.

It’s a good sign! It means they’ve got other reports for the same problem and are closing duplicate reports such as yours (and ours, probably soon getting closed as well). Only one is needed. So they are aware and will work on it.

I’ve got my bug report on blurry PDFs also marked as duplicate.

I like your optimism. Hope you're right.
 
Thanks for the info guys! Disabling Trim did the trick. It was a little scary when it said "might corrupt data on this drive". But I got to ask, what the heck is Trim?

Just google it. But it makes your ssd more efficient, and potentially makes it last longer and stay fast, rather than have speed degradation over time.

Personally I would NOT recommend disabling trim. Instead I am just waiting for a fix from Apple with 10.13.1 or 10.13.2 and tolerating the slower boot times until they do fix it.

I have experienced slow boot times only after the latest update. Also shut down speed decreased from intstant- 1-2 seconds to 25 seconds.
Decided to revert to cloned previous version of high sierra and all its back to normal :)
Btw: used CCC to clone.
Quick update...
Erased my drive, re-installed high Sierra and my boot and shutdown times are better than ever.
Currently in the (long) process to reinstall all my apps and find the culprit apps responsible for slowdowns. Will keep you all posted.

Thank, I also want to reinstall everything. If you have any news about they apps please send a update.

Yes the exact same thing is happening here. However I am using an unmodified 2013 Macbook Pro with iternal flash storage. Boot screen hangs at 70% for a few seconds, screen goes black, couple second later comes back on and boot finishes.

Has any solution been found yet? It's still doing this exact same thing :confused:

in my case, the problem is TRIM. When I disable it boot is normal, fast.

I have been experiencing this same issue since the original release of High Sierra. It's rather quite annoying, but I figure a future update in the betas will solve this eventually. Running on a early 2013 MacBook Pro Retina with maxed out specs.

Another thing I find annoying is how slow the new 2018 versions of Adobe CC lag like hell on it since I installed them. They are usable, but even though my computer is a few years old now it should be blazing through these applications.

I realize this is probably Adobe's fault for not optimizing their software for High Sierra though.

I too have reverted to plain vanilla Sierra because of slow boot/shutdown with High Sierra. Considering a fresh install but it's so tedious re-installing everything.

Yes, clean installs can be tedious but you only need to do it once every few years. This is one of these years, and you’ll be much happier once you’ve done it.

Clean install did not fix the slow boot problem for me, and a few others who have posted here.
 
Anyone with macbook pro retina 2015 running high sierra please share if booting slow too before I update mnie thanks

After updating high sierra my mac's boot time is very very slow. before instal it was about 10-15 sec. now maybe 1 minute. what should i do? (i tried reset nvram)
Click to expand...

The first reboot after a OS install will be slow.

First boot or always? After the install, the first boot of High Sierra is very slow. After that it should be quite fast though (on an SSD).

My boot times are decent on all four of my High Sierra machines, including two very old ones. I haven't timed it, but it's nothing like the 1 minute you describe.

I will also add that booting from a HD is much faster under High Sierra.

15 secs here.

Dammit. I wish I knew what the secret sauce was. My boot time on a crucial ssd in my iMac is close to a minute (even with a clean install) while my 2012 mbp with a samsung ssd takes about 35 seconds. So boot times seem to be all over the map for people.
Note: With Sierra, both systems booted in about 22 seconds.

Apple SSD has amazing read and write speeds. My MBP has a 256GB, and I believe 1gig of read and write speeds. After I updated to HS, my boot times were pretty slow (around a minute or more) so I tried everything (Reset SMC, NVRAM, safe boot... ) and suddenly after a few reboots and all of that , my boot speed was back to normal.

Yesterday, backup the drive with Carbon Copy Cloner and reinstall everything. I drop all the apfs containers and first reformat with HFS+. After install High Sierra Release 10.13 the system still starts slow. But then I reset the NVRAM https://support.apple.com/en-us/HT204063 after the step everything run perfect fast.

Now all App running again in fast boot up. Boottime 20 sec

Again, I've heard that from some. But I've rebooted probably 50 times over the past month with High Sierra, the boot times have remained consistent, and always slow.
 
Resetting the NVRAM seems to cause trouble in a Mac Pro 5,1 (boot loop) if you have a nVidia card and the webdriver installed. For these users this is not the solution. I stay away from HS at this moment.

I too have now wiped my Mac SSD and performed a clean install of High Sierra. Boot time is now a little over 20 sec, which would OK if it wasn’t half that with Sierra. Probably I’ll stick with HS anyhow, even though I can’t see that it does anything for me. Also worth noting that my Windows 10 machine, despite having a relatively slow SATA interface, now boots quicker than my Mac.
