Disc Permission MAC

Hi I have 3 HDDs one old-style HDD, one SSD drive, and one SSD Blade drive and I want to compare the speed between them but what are you trying to change the target drive it says I have no permission to do so even though I'm logged in as admin?

Any ideas?

Give that app full disk permissions under your security settings.

Already tried that, no change same message

See "wheel" and "everyone" have read-only? Change both, or at least "wheel" assuming that is you.

Does not work, I still get the message

I wound up having to call Apple Support directly and had them jump through a bunch of hoops in order to force the drive to change permissions to ALL. My opinion: this is a huge problem with Sonoma OSX, and a bigger problem with Sequoia OSX. Apple tries too hard to protect all our drives from being altered by anybody, including the people who own them. Lots and lots of Securities & Permissions problems.

So there is no fix for this?

Switch off security temporarily on boot and use the chmod command in the terminal.

Ok, how do I do that?

Go to this site:
https://macpaw.com/how-to/disable-enabl ... protection

and scroll down to "How to disable System Integrity Protection and enable it"
Follow the advice to disable.

After reboot, go to the terminal again and type:
cd /Volumes (Enter)

Now type: ls -l (Enter)
You should the a list of your storage devices and their permissions.

chmod 777 name_of_your_drive
If you now list the Volumes again, you should see full permissions on that device.

Don't forget to activate security again (see above).
(Normally, all of this should not be needed, you can give a program full access to drives in the Preferences. But something seems to be screwed up on Peder's system, so I explain the brute force method. It's still UNIX at the core.)

And for those in the know, I'm aware that you can combine commands in the shell

Yea, I just wanted to check the speed not messing with security stuff

Thxs anyway
