MacOS Big Sur - how do I disable/ skip verify on opening dmg I have 2015 MBA running Catalina that at some stage in the past I managed to configure that when opening my own created dmg files (used for business data storage with encryption security) it no longer goes thru the verify process when opening - just straight to asking for the password.
So I have bought a new MBA and installed Big Sur with clean install. Now I get the verify process each time I try to open my dmg files. Tried sudo defaults write com.apple.frameworks.diskimages skip-verify TRUE but it does not work. (In fact on my 2015 MBA, this flag is not set anyway).
It is extremely time consuming to have to go thru the verify process every time I want to open (several) of my data dmg files.
In response to a comment, I have set up a service as a work around that executes an automator service using shell script:
hdiutil attach -noverify &quot;$@&quot;
However, I find that I need to run the service twice in order to have the dmg file appear in finder - am I doing something wrong?
Finally - are there any other alternate solutions - given diskimagemounter does NOT verify dmgs when opening in my MBA running Catalina.
sudo spctl --master-disable
Above is the line that disables gatekeeper in Terminal.
This is not a practice recommended by security experts or Apple, yet it totally disables any dmg verification.
I use third party firewalls and security tools while keeping gatekeeper off.
