After installing security update 2021-007 on Catalina, MAMP stopped working and flags a bug with the graphics kernel
MacBook Pro 13″, macOS 10.15
This means that you can reinstall macOS Catalina WITHOUT DESTROYING YOUR DATA and then install the previously downloaded Security Update 2021-006 Catalina which still not contains the HD4000 bug. To do so
That's it. (Done so at Nov.27, 2021 on my Mac Mini Late 2012, Core i7 2.6 GHz QuadCore)
Now the most recent security problems (which are addressed by update 007) remain, but your Mac works as expected / as before.
That's a special compromise for a special situation. No more but no less. Hope that helps.

Yeah, I’ve tried with another created profile, but it doesn’t work. So they have offered to go for a time machine and reinstall OS.
The "previous working version" has security flaws. Thats the main reason for this sh*t... ;-)
You are absolutely right !
there is a simple way to go back.
You have to reinstall OS10.15.7 using the R command at startup.
This OS version does not contain the security update 2021-007 for Catalina.
It takes two hours for me.
Be confident : the reinstall doesn't affect all your data and apps. Only the system software.
That's what I meant with 'sustainable'.
BTW: I guess the HD4000 Driver is located in /System/Library/Extensions/AppleIntelHD4000Graphics*

Comparing the two systems (clean install and install with security update) the extensions for intel GPU HD4000 are absolutly identical. Same size, same date.
Hey, do you have any further tips on how to do that?
I am kind of lost here.

Verify your MAMP software is up to date — v6.6 is now available
Let's hope Apple fix the problem in an upcoming Security Update.
It's a good practice to backup before any system update.
You never know, right?
show me where i repeated myself in that context more than once to the same person. go ahead.

You're welcome :-)
It's not the 90s. A computer without updated security software is not a fully functional computer.
Okay, never mind, we’re done here.
