Specifics: Mac OSX El Capitan Time Machine is from an older mac that this new mac replaced. Both running El Capitan.
The specific issue I am trying to solve is that some folders show the red circle on them indicating that I do not have access to them. I have been able to gain access to them by right clicking, choosing get info, adding the current admin user to the list of users in permissions (because they are not there) and then instructing the system to either apply the changes or make the user I just added the owner.
Now, I was able to figure out that the command line to do this enmasse is as follows: sudo chown -R user rootfolderoftimemachinebackup
I then enter the users password. I get a large number of Operation Not Permitted results but largely I this command does what I want. I am curious if someone out there can explain to me the method I would go about in gaining access to the files where it says the operation is not permitted. I have attempted the manual process explained at the beginning of this post on those specific directories. However, when I attempt to add my user to the list of users it tells me I don't have permission to do that. Well, I am the admin on this machine and the file I want to do this on resides in a time machine volume that is no longer mounted as a time machine volume. The file I am attempting to take ownership of is a windows file from a backup of a windows folder from a long time ago. It probably can be deleted, but for my own knowledge I would like to resolve this so that I know how to eliminate the problem.
One post that I saw indicated that I needed to boot with COMMAND-R and in this mode to run Terminal and disable csr. I have not yet tried this yet, but if someone can confirm the reason for the errors is because System Integrity Protection is turned on, I will turn it off.
The post I refer to is here
Thanks for any help you can provide, I will check back on this post tomorrow and answer any additional questions you might need answered to assist me in getting to the bottom of this.
I have checked out the following questions to see if the answer was there.. and so far nothing.
