Hello, guys!
Does anyone know how to make a disk that's being shared via Share Disk mode read only? As you can see below, these are the privileges that I see when I click "Get Info" on my drive. However, when I share this disk with another M1 MacBook, I am able to delete files from it. How do I disable that?
Thanks in advance!
MacBook Pro
Hi! It’s the new version of Target Disk mode. When you use a wire to connect two macs, then turn on on Mac in special mode.
Transfer files between a Mac with Apple silicon and another Mac – Apple Support (UK)
How are you logging into the Mac that is the host? If you are remotely logging in using an account on the host Mac, you have exactly the same permissions as if you logged in directly.
If you want to control access to the drive, create a Sharing Only User in Users & Groups and Share the drive out to that user as read only. Log into the Mac using that user.
If there are multiple users, create multiple Sharing Only users and create a Group for them all. Add the drive to Sharing using that Group as read only.
Thank you a lot for your time! I’ve done a bit of research and have jumped to the following conclusions.
It looks like an external drive in GUI, when in fact it’s operating over SMB protocol. That’s why diskutil doesn’t see it and diskarbitrationd can’t prevent it from writing (tried both adding settings to /etc/fstab and turning off disk arbitration at all).
I was looking for a forensically sound method but seems to me as if it’s dead when Target mode was deprecated :( Thank you all guys for your help, I really appreciate it. But looks like you are right, no way to do so without any physical write blocker.
That doesn't work the way you want. It just mounts the drive as if it is an external. There are no restrictions on access.
Hi! I am actually using Share Disk (through recover options). Transfer files between a Mac with Apple silicon and another Mac – Apple Support (UK). I connect them through a USB Type-C wire.
Is this Disk and External Disk or an Internal Disk
In illustration below - have an External Drive Attached and do not see a " Share Disk " in " Sharing " Applet of Preferences
It’s the main disk of my second MacBook. It’s supposed to be treated like an external one to my first MacBook when this mode is on.
Share Disk Read Only
