Extra Internal Drives - Read Only/Read/Write

[Siegfried Meier]

Hey guys,

I'm having something odd happen to an internal SSD audio drive that lives in our Macbook Pro. This system actually has 2 x 1TB SSD's in it that are partitioned twice - so there's actually 3 operating systems running on it, and the 4th partition is the audio drive itself.

So I bounce between Mountain Lion/Pro Tools 10HD and Sierra as well as High Sierra on Pro Tools Ultimate 2018.4 for various tasks. I've noticed when I do so, all the sessions and folders on the audio drive become read only, and I have to manually click "get into" and check off the privileges to read/write for all users...every time.

Is there an easy way to manage this better? A global way to do it? I've tried setting it to the entire drive, but it doesn't work for all folders enclosed...any insight would be much appreciated here!

Thanks,
Sig

What about checking "Ignore ownership on this volume"? Does that not stick?

Sadly, does not...

Mmm I am not sure what exactly could cause this.

What type of filesystem is it?

One way to have similar problems to this is to be booting between different OS installs and have folders used by what you think are the same user, or users with the same user name on those different OSes, but they are really not the same user as they have different user IDs (uid) on the different boot OS images. You want to ensure the uid for the “same user” on all systems is the same. From the terminal type “id -u” and see if the numeric uids match.

That does not exactly sound like the issue you are facing, but I would still check it out. You still might have something bizzare going on with user or group ids not matching across systems and maybe software resetting permissions where it does not recognize a uid or gid. You can check and do individual brain surgery to fix things here but an easier way may be to put everything you need in an user account on one of the images and then use Migration Assistant to copy that account to the other images, just the user account, not all the other stuff Migration Assassin can uh assasinate.
