Today i've installed macOS Big Sur on my mac mini and everything seems to work fine (for now) but it also re-installed the standard apps like Chess and Stocks again after i removed those when i was still in Catalina.
Now i tried the same method in Big Sur like on Catalina but i was unable to delete the pre-installed apps and got this message in Terminal :

mount_apfs: volume could not be mounted: Permission denied

mount: / failed with 66

Has anyone tried this yet in Big Sur and have a solution for me ? :)
 
My guess is that this has something to do with the way the boot volume is crytographically signed. Check this out, specifically the part about the security features on the boot volume:

 
Interesting read Bluedog314, thanks for that.....I have commented on an article provided by a link in the review so hopefully I get some more insight if it is possible or not to remove the preinstalled apps.
Keep you posted....
 
Thanks for the links....

I got some response on my question in another article and basically you can't remove the pre-installed apps.
You may be able to but then FileVault and other encryptions will never be able to be turned on again which in turn makes booting impossible.
Apple has really gone all the way with Big Sur security wise pfffff
This is the reply i got :

Trust me: you really don’t want to do this in Big Sur. As explained above, in order to do this you have to break the seal on the System volume. You can’t then reseal it. Ever.
Furthermore, users are reporting that before you can do that, you have to disable FileVault, and it doesn’t appear that you can re-enable that either.
If you really want to do that, then the basic requirements are outlined above, but you’re out almost on your own in doing it, and will have lost two of your two major security protections. I wish you the very best of luck – you’ll need it!
 
It's actually easy to delete the pre-installed apps in Big Sur. Right click on your hard drive and select Manage Storage.... Select Applications from the sidebar, highlight the undesired app, and click the Delete button.

yes, however... apple's default apps do not show in that window...
 
Thanks to all for this discussion. I guess I can stop hunting for safe ways to do this. I hate proposed "updates" on apps I don't use cluttering up my App Store list, and the only way to get them off the updates list is to keep accepting and installing updates to apps I don't want.
