Description Jo 2019-06-09 17:10:31 UTC

SUMMARY
I know gamut masks were introduced before version 4.2, but these gamut masks show up only in version 4.2
Now my problem is that my computer works very well but I can't upgrade it higher than 10.11 due to hardware requirements I assume

EXPECTED RESULT
Krita Version 4.2 requires Mac 10.12, and honestly I don't accept Apples quick and arbitrary update strategy. So much that I installed Linux weeks ago but there I can't work as usual. Krita 4.2 works flawlessly on my Linux installation so why it shouldn't on my Mac 10.11?
New Mac Os versions introduced nothing useful just eye candy. So why bother and follow such useless update policies? 

SOFTWARE/OS VERSIONS
macOS: 10.11
Krita: 4.1.7

I'm sorry, but we're not going to backport this feature to a branch we're not going to make releases from, and we're not going to support versions of macOS that Qt doesn't support either. Apple has decided to introduce new API's and retire old API's, and Apple is always right. If you decide to use macOS, you should be prepared to let Apple decide what's best for you, and always, without a moment's hesistation, follow their lead and do what they tell you. That's what being an Apple user is all about, after all.

So I assume that getting gamut masks isn't possible just by moving some plugins from newer krita into my older krita application package
..and if possible, then krita 4.1.7 wouldn't be able to access said plugins as there's no code in older krita to invoke the plugin for gamut masks 

Very sad about as I was waiting joyfully for this feature which I myself had requested time ago. Apple isn't the same anymore. 
There's a menu for scripts in krita but I don't know if this menu entry is already usable in 2.1.7. A python script could generate a simple palette but I've no idea his to do this.

Newer macOS versions did change more stuff than just eye candy. They deprecated libraries and changed their API.

Making the Gamut Mask work on an older krita version would require a little more effort than just copying some lines of code. You could try either porting the gamut mask to the version of krita you are using. try to compile newest krita on old qt-5.9, or as Apple would suggest, get a newer mac :p (In my opinion is best  to switch to linux as you stated it works flawlessly :)
