I did not (yet) upgrade my system to the latest macOS update (Tahoe 26.1) because after taking a look at the change log and security notes (see https://support.apple.com/en-us/125634) I am suspecting that installations from the sister site could become heavily affected. Almost the entire article lists measures to tighten apple's security architecture, which could make it very difficult or impossible to install certain software.

Could one of you wonderful people who knows the subject (keywords like codesigning, gatekeeper, symlinks, etc.) take a look at the measures to be implemented?
I would like a recommendation on whether I should steer clear of this update or not.
It would also be good to know whether releases and the steps during installation can be adapted to the stricter conditions if necessary.

P.S. Please no blanket advice like “always avoid updates” – I already know that.
Thanks in advance.

 

They are bugs and vulnerabilities they are fixing with their regular updates. Each one gets its own CVE number as they get reported, tested and fixes added to the OS. Unless you see a specific CVE to look at, it appears entirely normal from them. If you look at the names of those who have submitted like "RedTeam", etc.; you can see they are mostly or completely security researchers.

 

Thanks for the fast reply. I read stuff like "Description: A downgrade issue affecting Intel-based Mac computers was addressed with additional code-signing restrictions. CVE-2025-43390..." and I know that this must directly affect some of the common k'ing methods.
You surely remember the whole story about Pulsar Modular and removing the intel slice etc.
Of course, Apple doesn't mention exactly which restrictions will be taken.
And I start feeling insecure because I know it is good to keep the system up to date, but I hate those nasty surprises when the stuff that just worked suddely refuses to even launch.
I would be very thankful if you (or one of the other knowing ladies & gentlemen) would take a closer look.

 

And how might you possibly know that? All you are looking at are patches for MacOS. They are usually all little stuff that has never even been found in the wild used for a zero day exploit. It's a brand new version of MacOS, and they probably still have less bugs to fix than the monthly Waves updates.

 

Trying not to use generalities here, but with that document (just as microsoft is on the win side) they are purposely being vague AF about every "bug" on that list. Microsoft takes it one step further wherein every patch is described with one or two simplistic catch-all blurbs about "this is a security flaw" or this is a "code fix for x,y,z". A lot of times they will reference a microsoft KB (microsoft knowledge base article) number that in many cases is either moved, or been assigned a different number, etc. If one is actually lucky enough to get to the correct KB article the verbiage used to describe the patch, or whatever it is they are wanting to install on your system, will again be purposely vague and cryptic.

Take for example that first one on your list;
"Admin Framework. The issue was addressed with improved checks." Doesn't tell you squat.

Then there are "reference links" pointed BACK at the same page you initially got the CVE from...THEN it points to an "apple advisory" that lists another "reference article" pointing back to the page you started from...

As the final coup de gras, they expect you to paw thru this list of "Child vulnerabilities".

By this time, if your head isn't spinning around like the exorcist girls', you're sorry you even tried to figure out what the initial patch was for...

This is the way it is on both platforms. Trying to determine exactly what is being installed with these "updates" is almost impossible - the sheer length of the lists, the misdirection and purposefully cryptic language describing them being major factors in the design. They want the process of figuring out what it is they are installing made as difficult as possible. So when the application of all those updates in one session totally racks out your machine to the point where it's unusable, they can just say "well we told you all what it was we were installing", see?

Your initial assessment that a significant quantity of stuff on that list has the potential to make it harder to run warez, or make personal privacy changes to the appleOS, is most likely correct. After all you are the end user, why should you have any say in what you want to run on your own machine? (purposely sarcastic)

The crux of the biscuit is this; Asking someone else to figure this out is a full time job for that person(s). Most likely if you want real info on that list you can start by googleing the CVE numbers and see where it leads.
