I have problem to access my Macintosh HD even I'm admin, I can't change sharing & permissions when I go to Macintosh HD info, I get only message: "The operation can’t be completed because you don’t have the necessary permission." This start happening when I start using High Sierra. If someone have answer to this question please help. Thanks.
In High Sierra, you cannot change the permissions on the root level of the hard drive.
If it is an external drive, you can set it to "Ignore ownership" in Get Info.
Or, you can just create folders at the root level to use instead. Once created, you can modify the contents without authenticating.
Could not agree more!
Err......Idiots like QuarkXpress you mean? I guess you drive a car with the hood welded shut!
Apple seem to have forgotten who actually owns the computer!
I'm actually erasing my hard drive in about 3 minutes and taking it back. I'm so disappointed in apple. It's too bad.
Thanks for responding! Both Norton and Parallels were unable to complete installations because of this issue. I honestly didn't look up to see if there were fixes for either of these apps on their sites. I ended up trying what another person posted and disabled the SIP. Everything installed fine after that. Although the work around was simple, this seems like such an unnecessary and annoying update for OS. Is this just to help security? Anyway, thanks for the response. Everything seems alright now.
From Terminal, when you enter this string, do you actually see a root ?
dscl . list /Users | grep -v "_\|nobody\|daemon"
So you're saying ADMINISTRATOR ACCOUNT ROOT level you can not change anything ?
as in you can navigate here Nor Able to change things? - Are you changing System files ?
Have you tried to create another account and give it admin privileges ?
You could probably also escalate the authority of the 'root' account to what it should be if it's not set low enough - it should be set to ZERO (0), is it in-fact that when you run from terminal:
dscl . list /Users UniqueID
I had this permission problem using AVID Media Composer. I found two work around solutions to be able to transcode or consolidate the editing:
1) Create a new partition. The new one shows up in the transcode/consolidate menu. But I still had an error message when launching the application Media Composer (without any consequence probably).
2) Disabling momentarily the SIP, changing the permission of the hard drive folder (Get Info-->Sharing and permissions-->everyone Read&write) and locking back the SIP. It works fine now.
To disable the SIP:
Boot the computer in Recovery Mode: cmd (⌘)+ R
Open the Terminal application (in Utilities folder of the Applications folder)
Write: csrutil disable; reboot and Return key
You should see somewhere: "Successfully disabled System Integrity Protection. Please restart the machine for changes to take effect."
Restart the computer.
To check if the SIP has been disabled, you can reopen the Terminal application. Write csrutil status and Return key.
You should see: « System Integrity Protection status : disabled »
In this case you can change the protection as said before.
To reactivate the SIP:
Again boot the computer in in Recovery Mode: cmd (⌘)+ R
Write csrutil enable; reboot and Return key
You should see now: « Successfully enabled System Integrity Protection. Please restart the machine for changes to take effect. » Restart the computer.
Voilà !
Your solution worked like a charm. Thank you very much!
