extremely slow after update 10.13.4

Hey,

I have exactly the same symptoms, I thought CaptureOne had trouble with the update but it's actually my macbook that became slow beyond reason. 10.13.4 really made a big performance drop, I can't use my computer for my daily workload without frustrating lags on every action.

Please, Apple, fix this.

So I understand what the problem is:

10.13.4 brings external GPU support for many notebooks and desktop macs. Apple must have change something in the GPU usage in macOS to enable such a support, but ended up breaking integrated GPUs in some machines, maybe older machines (mine is a 2011 17" macbook pro with discrete GPU).

I noticed the difference right away in CaptureOne but FinalCut seems fine, which may lead to think that apps should be upgraded the Apple way to work fine in 10.13.4 ? This would be totally unacceptable but hey, Apple is king here.

Anyway, I ended up disabling hardware acceleration to rely solely on the CPU graphic chipset in CaptureOne and of course, it "solved" the problem since the GPU isn't used anymore.

I hope a fix will come soon.

You are right that 10.13.4 brings some slowness to intensive graphics operations on certain older Macs.

Whether or not the issue applies here, the problems shown are so large, there is no way to measure graphics slowness -- mad50 Mac is so overwhelmingly slow it is unusable, and that major slowness is NOT caused by graphics slowness.

Same problem 😟. I have a MacBook Pro Retina Late 2013 - before the update it was working great, NO problems, very fast. After 10.13.4 it became PAINFULLY slow with everything, almost unusable for a regular work and anything else. I tried to play HearthStone - it is a REAL pain watching it, all graphics became ultimately slow.

I have just found at least a small solution (it got somewhat better afterwards) - try to disable "Dock animations" and "Font smoothness" in System Preferences. As my MacOS is non-English, I have no idea how they are properly named, but you can find both in 1) Main Settings (the top left icon) and 2) Dock Settings (third icon from left in the first row).

Hey, I was talking specifically in CaptureOne, and it works in the Adobe suite as well, it's not a fix for macOS.

So in these softwares, you can go in the preference pane and look for Hardware acceleration. Then disable everything.

There is also https://gfx.io/ that let you force internal Chipset over GPU, but you won't be able to connect an external monitor anymore (at least in my own experience).

I didn't try Xelago solution yet, it might work for you!

Have a good day!

I did as suggested and it worked, but only for a while before everything went slow again. However, I noticed that each time I reboot with font smoothing off, the issue starts again once I launch Safari and goes back to almost the normal speed when I quit Safari.

It appears there may be something related to Safari rendering engine that's causing it. I've in the mean time switched to another browser for now.

I found out what was my problem - I had a defect accumulator which caused this massive misbehaviour and slowed down my Macbook Pro like ****. After a replacement (non-original Apple accumulator by the way) everything works as it was before, great speed etc.

Why do they always come in with an update thats helpful only to products newer than 2/3 years?!

And further why it 'breaks' something in devices older than this!!

We know it increases Apple's profits/ growth but how about a survey on how long our Apple products from Steve Jobs' days used to last...and how long we keep them (without issues) today?

I am not computer literate however I got to thinking about the slowness of my 15 inch MacBook Pro Mid 2015 machine after upgrading to High Sierra 10.13.4. Most of my issues were very slow downloads using Wi-Fi. If I wired directly to my router my downloads were much better. In one of the recommendations that I thought interesting, was to switch the browser from Safari to Google Chrome. I installed Google Chrome and gave it a try, download speeds increased from 39.5 mbps to 45.2 with Google Chrome, what happened with Safari was the speed increased to 51.6 mbps. Hard wired I get downloads of 90.0 mbps. I really do not understand why installation of Google Chrome helped with Safari but it seems to help enough that I can live with it. Is there is something going on with the interface between the MacBook Pro and the browsers that may have been overlooked?

I disabled "Dock animations" and "Font smoothness" in System Preference. I also tried resetting PRAM and SMC. None of these changes helped.

I had installed an SSD into my MacBook Pro to speed things up. It was great until a Mac OSX update corrupted my main user account. I was forced reinstall and take the latest Mac OSX update.

I was worried about 10.13.4 as I heard it was slow. It is now slower than when I had an HD

The CPU usage and memory usage is low.

I am an instructor. It is painful to do presentations with my MacBook Pro now.

The problem is the apps are slow in starting up. Once it is up, it seems to be okay. So is switching users.

The quality of Mac OSX and IOS updates have gone down.

I meant that switching to another user accounts is painfully slow.

I have a Mid-2010 Apple MacBook Pro "Core i7" 2.66 15". I have more memory in the MacBook Pro.

Let me know if the installation helps the speed.

Unfortunately 10.13.6 ended up only fixing the problem for a few days. Now on 10.14 Beta 4 (Developer) and everything is finally running smoothly (fortunately there are no significant app incompaibilites that have affected me)
