High Sierra Unbearably Slow

I have updated my MacBook Pro to the new developer beta and it has become extremely slow. Something as simple as opening Safari makes the fan turn on full speed. Any suggestions?

I'm curious what MacBook Pro you are using specifically. While High Sierra has not made my Mac slow, it has made it unbearably HOT and the fans run all the time. I have a late 2011 15" MBP and on my machine automatic graphics switching constantly uses the descreet card and never falls back to integrated graphics, making the battery life last about 45 minutes, fans run constantly, and it is HOT. I had a similar issue with the early Sierra betas so i'm not concerned - it will get fixed. It's just annoying for now.

i have an early 2011 macbook pro

When i restart my MacBook, i get the message “You have restarted your computer because of a problem.” So even the computer can detect something is wrong. Could it be an application that isn’t compatible?

For the crash saying "You have restarted your computer because of a problem." I've to disconnect everything possible from my MBP. After reconnected all devices step by step I could identify an USB device that has a "not so Mac-like software". For now I keep the device disconnected.


My MacBook Pro is also really slow. It's because of the trustd process that keeps running on high CPU usage. After a lot of patience and some hours of waiting the CPU usage becomes lower and the mdworker process comes up. I guess it's because of the APFS migration and I hope it'll finish one day.

Hi! I have the same macbook model!


I am curios about your configuration.


As I know your Macbook Pro late 2011 ( 15'' ) is not compatible with Metal technology.
And here we go:


macOS 10.13 High Sierra uses Window Server on top of Metal 2.

Do you see a contradiction?


macOS uses Metal 2 under the hood of Window Server.
So, old macs COULD have big troubles with it.


I will be glad if somebody show information which falsify my contradiction.

trustd has been using the majority of my CPU also. haven’t had any luck with it

Try signing out of iCloud, restart and then sign in again.

After about 30 minutes of slowness, i did as you said and nothing seemed to change. trustd and spindump are still using a huge amount of CPU

I have an iMac 2011 with an SSD inside on which I ran the High Sierra update: here everything works out pretty fine. But my MacBookPro, which is Mid 2012 15" got a fresh new installation and just does not work. It is not slow, it just does nothing really. After a minimum of 30min. waiting to reach the "Shutdown" option in the menu bar, the MBP was not able to shutdown and it showed me a really strange screen. Nontheless I suppose that I has not only but also to do with the hard drive which is an old HDD. I am currently loading the actual Sierra OS with which I was quite satisfied.


Hope this will be fixed otherwise I might either stay with the old Sierra or got to get myself a new MBP

Spotlight will often cause a high CPU rate after an upgrade.

well it’s been over a day so i think there’s a bigger issue

I have a late 2011 MBP running High Sierra. Under Sierra on idle, I had 1.3GB ram free on a 4GB ram system. Under High Sierra, I only have 400MB ram free on idle.
Also, Safari hogs ram and CPU like no tomorrow. So much for it being the most efficient browser :/


I definately think that High Sierra is a performance downgrade, at least on this older hardware.

I'm seeing the same issue, but the strange thing is that my CPU is not running high. High Sierra is still very slow. Especially with web browsers it seems. I'm working on a MacBook Pro (Retina, 15-inch, Mid 2015) with an i7 and 16GB RAM, so... I think it has to be a flaw in Sierra. I guess that is why it's a BETA. 😟 It's just very annoying in the mean time.

I've been wondering about this myself. I have a late 2011 15" MBP. It indeed runs High Sierra (quite well actually, except the no sleep/wake and constant dedicated graphics card issue). I know my machine did not support Metal 1 graphics, and I assume it does not support Metal 2 graphics, yet, there it is, running High Sierra, which allegedly uses Metal 2 for the WindowServer. Only explaination I see is that the WindowServer is still able to fall back to the previous (OpenGL?) rendering on unspported machines? If my suspician is true, I'd also suspect that this will be the last release to do so and 10.14 will drop support for all non-Metal supported machines.

Same issue here with constantly running dedicated graphics on a 2011 15" MBP. In the ealier Sierra betas there was a similar issue, but it was more that certain apps caused the dedicated card to kick in when they shouldn't have (false dependencies). I was able to identify these and resolve them one way or another. The system itself still would fall back if NO other apps were running. Under High Sierra, I can't get the machine to fall back to the integrated card no matter what. No dependecies listed in Activity Monitor. The dedicated card is still used in Safe Boot and in Recovery mode. I even, just for kicks, removed all of the AMD graphics kexts. Even then, the system will boot using the dedicated card, essentially in VGA mode. IMO this appears to be firmware, not software causing it to not work. I have not tried booting into Sierra to see if Sierra still functions properly. High Sierra did in fact install and EFI update on my machine (though I assumed it simply added APFS booting capability).
