(High Sierra) Dock Icons get missing at all the time

Start in safe mode. As discussed above. Then after they back. Restart in normal mode.

Run NVRAM / PRAM see this article How to reset NVRAM on your Mac - Apple Support

I had the same issue. I resolved it.

Steps:

1. Quit application
2. Right-click in dock > hover over options > select remove from dock
3. Open launchpad and drag icon to the spot you'd like
4. Fixed!

Cheers!

I would perform what many here don't like but always gives me a stable and reliable machine every time I apply an update, minor or major: deep and complete cache cleaning with (in this case) Sierra Cache Cleaner.

HTH.

Great tip. I used this tip to simply Remove the icons from the dock, then drag the icon back from the Application folder.

Worked for me.

YES!

The LOL Game app - not the Launcher, but the actual game - is always the first app to show this erratic behaviour!

This might be a good hint for the bug-hunt. I will check this with the Riot player support.

Anyway - can you give any further details?

It's not in System Preferences.

Go to Finder and hold down the option/alt key while selecting the Go menu item. Select "Library".

I don't know about you, but my contact with the Apple support told me the problem was the game League of Legends. Anyone can confirm this?

This is a silly workaround, but here's what I did:

Go into the applications folder, and pick the app whose icon is not displaying properly:

Drag it to the desktop to create an alias:

Drag the Alias that has the correctly displaying icon to the dock:

Then remove the old icon that is not displaying properly.

I only had 5 icons that were not displaying when upgrading to high sierra, so it was not too cumbersome.

Don't be so sure about that atlonxp,

Today is January 5th. I have just installed High Sierra because there was a very persistent message (even inconvenient) on the top right of my screen. After a daily fight to get rid of it in a gracious way and overcome by fatigue, in order to pay attention to my own work, I just gave up after a few months and upgraded today. Now I have the same problem: lack of several icons on the dock! No Apple didn't address this bug yet!

The thing is that Apple gets more and more expensive, and more and more problematic. I'm really almost done with them, after purchase 1 iPod, 2 iPhones, 3 iPads, 2 iMac, a Macbook Pro and lots of other things including software that now doesn't work because they "upgraded". Apple is not answering. Apple is leaving their men behind. I'm very sorry.

There's no such thing als "Apple's support for this". At least not in these threads here. It's a user-based discussion&help group.
If you still have Apple Care, they will try to take care (just call them, they are nice guys). But in this case, it's a software bug - and unless they work on it on the developer level, they won't be able to help you either.

Quality of Apple products and software should be addressed as a No.1 issue by the company. Everyone knows this isn't the case right now. This is a showstopping error if it continues. But if they have ears to hear, they know this already.

I am having this same issue of icons dissapering ever since I updated, this is a very annoying issue that needs to be resolved ASAP. Does anyone know how i can fix this for the time being? Ive tried kiling dock command nothing seems to work.

Hi Rashdude,

I hope it's not too late:

The "Menu" mentioned is the menu you'll see when your currently active app window is Finder.

From there, click on "Go", then press "Option" on your keyboard to make the "Library" item appear.

I hope that'll help you.

Sorry TA_Allan (spelled you wrong in my previous rave of your post, my bad)

Yours is both the simplest and only solution that worked for me. I do have a weird arrow pointing to the new (proper) icon (telling me it's a copy?), but I'm much happier to immediately recognize my most-used applications. Gracias! (btw: my mac genius husband, who is totally blind and whose mantra is "for crying out loud, stupid sighted people, open your eyes" obviously couldn't care less about the generic icons. He's my go-to for most techie quirks, but for this one I had to crowd source.

Thanks to all of you for taking the time to share your fixes.

While this is entirely a possibility that the LOL game app triggers this, there should be no way any single app can completely wreck the operating system's icon cache/subsystem. I'm still hoping for Apple to provide any sort of acknowledgement of this issue.
