Just updated my Mac to Mojave today.

Liquify is creating black pixels when used.

I have tried to optimize performance but I still get the same error.

I have a super fast machine, so is not a RAM error. Liquify was working normally before Mojave OS.

In the image below, I have slightly adjusted the smile of the subject.

This doesnt work for me.

Apple has just released the 10.14.1 Mojave update so install that and see if the Liquify issue is solved.

I get the same issue. It's very frustrating because i used the OPT+click workaround to create a gif and it worked. No pixels were created. I just reopened that file again to edit it, add more frames to my gif, and it added liquification to all the previous frames in my gif!!!

It is depressing. What to do, besides to change something in the system?

Because Adobe can't do anything already 4 months from Mojave release or how to resolve problem yoursef.

Painless rollback from not working 10.14.3 to working 10.14.1 Mojave, if you haven't 10.14.1 time machine backup. How I did it today.

About an hour of work.

I found on the internet 10.14.1 Mojave file. Not simple update file. Normal full macos distributive. (it was a bit difficult because you cannot download this version direct from apple link. From apple you can find 10.14.1 update file or 10.14.3 distributive) You can pick my distributive or find it yourself - ( macOS 10.14.1 Mojave.dmg — Yandex.Disk )
You need to download it.

I think that you need to create full time machine backup just in case.

Turn off your automatic system update in system preferences.

Then you need to create bootable USB with this distributive.
Open the downloaded macos file(double click) then drag "Mojave installation" program to your applications (like another program). After that you can create bootable USB like in this tutorial: https://www.macworld.co.uk/how-to/mac-software/bootable-mac-install-drive-3575875/ with small changing. Read below

Plug in an external drive with at least 8GB space (preferably 12GB) as that’s how much the installer will require.
Launch Disk Utility (press Cmd + spacebar and start to type Disk Utility).
Before this next step - if you are running High Sierra you will need to click on the View drop down below the close minimize buttons. Choose Show All Devices from the options. Now you will see the external root drive in addition to the volume below it.
Select the root drive in the sidebar (the next step won't with if you only select the volume).
Click on Erase.
Choose Mac OS Extended (Journaled) as the Format.
Choose GUID Partition Map as the Scheme.
Your drive will be called Untitled by default, you could give your drive a name such as "USB". (Note you just need to replace the term USB in the Terminal command with the name of your drive).
Click on Erase.
Wait while Disk Utility creates the partition and sets up the drive (this can take a few minutes).
Then click Done.
Open Terminal (the easiest way is to press cmd+space bar and then start typing Terminal). Copy the following text into Terminal for :
sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --nointeraction (i already changed command for Mojave)
Click Enter.
Terminal will ask for a password. This is your user password. Note you won’t see characters appear as you type it in, that’s fine. After typing in your password, press Enter.
Terminal will warn that it is about to erase the drive (so make sure there wasn’t anything important on it!). Ifyouwanttocontinue press Y and then Return. The process can take a while, you'll see “Erasing Disk: 0%… 10%… 20%… 30%…100%…
Now Terminal will spend a few minutes copying the installer file to your drive. "Copying installer files to disk… Copy complete" and so on will appear in the Terminal window.
When Terminal has finished copying the installer you will see the words Copy complete and Done appear.
Now you have the installer on the external drive you can use that to install multiple copies of macOS. Plug the external drive into the Mac that you want to install the macOS on.
Start up the Mac, holding down the Option/Alt key while it is booting up.
Your Mac will display the Startup Manager, click on your external drive and select Install macOS.

Then you can simply install this version from your USB over the top of 10.14.3 on your system hard drive without format your data. (i don't know why, but it worked in that case) All your data and settings will survive like after simple system update.

Now you have working 10.14.1 Mojave, (i hopefull that) have a nice day!

Hi, i have updated Mojave to 10.14.3 and photoshop to the last update, but the problem with the pixel in liquify is still there.

I have see that if i switch off the graphic acceleration the problem there is't.

What we can do?

Thanks.

Working real fix!

If you copy all kexts "starting with AMD" from System/Library/Extensions from a Mac with 10.14.1.

You can then use a free program for kext installing found online to put the working 10.14.1 AMD drivers into your not working 10.14.2 or 10.14.3!

Adobe moderator decided to remove my previous post from the forum probably because I mentioned another program?

So cant tell you what program to use for the install of the AMD kext from 10.14.1 or have a tutorial with images which is incredibly frustrating...

But this really works!

You just use the program to put 10.14.1 AMD drivers that worked back into your 10.14.2 or 10.14.3 system.

The reason you need a program is because you cant just drag and drop the old drivers in the newer system...

But if you do this you don't need to roll back the entire system but just the drivers.

Should work for all builds that had a working liquify tool on 10.14.1 that had the artifacts return in 10.14.2.

And I tested it on My 2013 MacPro.

Thanks for that solution.

However changing the kext files/graphics drivers is not something i want to do. There are other programs besides adobe's and those rely on current drivers and i don't want to compromise those.

Given that this solution works, it's even more clear where the problem lies.

Apple has updated their drivers and OpenGL to newer standard, but photoshop is still using outdated libraries and routines for the gpu.

The fact that these artefacts show up, is possibly caused by adobe using OpenGL drawing routines that were not intended for compute work, but only for graphics display. (display routines don't need to be error proof, nobody will notice a small artefact in one frame when there are 30/sec.) OpenCL should be used for using the gpu for compute routines.

The 10.14.1 AMD drivers work perfectly fine within a 10.14.2 or 10.14.3 system.

It is a solution to a mayor workflow problem and still have some of the benefits of the newer system.

If you should encounter a problem with any other software you can just as simple reinstall the 10.14.2 or higher drivers within the time it takes to do 1 reboot.

honestly scared to do the update in case it screws up something else. enough compromises for now!

i still have to toggle graphics processor off and on for liquify, and i have to only have rulers on when I need them, otherwise I cant use spot heal or clone. *rolls eyes*

In order to make the things easy for now:

1.- make two little actions to enable and disable de graphics processor and assign them to shortcuts

2.- with graphic processor ENABLED (of course) make your liquify work normally and click OK

3.- make undo (Command + z)

4.- run your action to DISABLE graphic processor

5.- make Control + Command + f

6.- run your action to ENABLE graphic processor

NOTE: This don't work with the Face-Aware Liqufy tool due this USES graphic processor, but works ok for the other Liquify features. Good luck!

I'm using it like this but I hate Mojave, it's slow and I get the spinning wheel all the time. My mouse is slow to respond and even though I downloaded new drivers to my graphics tablet so it works it is super slow and sometimes nonresponsive. Also, my photo files on my external hard drives are hard to access slow response time has forced me to sort and upload photos with my old mac book pro that I AM NOT putting Mojave on. This system sucks! It has made my MAC feel like I am working on a crappy PC. thanks for the help --- I'm supper disappointed with Apple right now.
