Disk not ejected properly

I have had this issue for so long I cannot remember when or which OS it started in, however I have been running the Release version of macOS Sierra courtesy of Apple for four weeks now, and it has not occurred once, I am hesitant but it seems to be fixed.

I hope you are correct. Have not been able to corroborate yet online and haven't been offered Sierra. Figure I will wait until Apple tells me its available.

For the past two days, one of my disks has been going crazy with this message. I am used to coming back to the computer in the morning and seeing one message, but not I come back and wake up the computer, and I am seeing like 8-10 of these messages at one time, for the same drive! Is anyone else seeing this behavior recently?

Yes. But on and off. May happen when Mac "awakes" at night for updates or things that happen through Safari which is a backbone of the cloud environment for Apple. Would be nice if Apple told us what they have been doing about dnpe s all these years.

"1) I think those instructions incomplete: what happens to the file moved to the desktop? how does one avoid side effects like loss of connectivity on WiFi and to other cable-connected devices? 2) I am chary of changing the computer name (when I had problems with a new iMac, changing the computer name seemed to complicate the problem). 3) If this is a valid fix to many of the many thousands of problems out there: why hasn't Apple (a) sent out a general advisory or (b) incorporated the process into a major upgrade, as to El Capitan (or even done much the same thing invisibly)."

Agree with these points - and if it was a valid fix, I think that Apple (or someone) would put out instructions via the command line to perform whatever tasks the system performs when the system configuration folder is absent / rebuilt (I'm assuming the "answer" post by Robster meant that it had to be moved, not copied, otherwise you would just be changing the share name of the computer - though I agree with the poster above that it can't be moved or deleted, so I'm guessing that may have changed between Jan 2014 and 2016).

@Robster50 - if you are still active, can you elaborate on "5. Pull this folder onto the desktop." - as mentioned below, this folder cannot be moved or deleted, only copied. Was that different in 2014 when you did it?

Robin,

Many thanks for providing this solution! Two questions:

1. Just to confirm... you drag the SystemConfiguration folder out onto the Desktop, not copy and paste, correct?
2. Will that folder be re-created?

Thank you.

Yes to both questions.

This seems to have done the trick for me on my 2012 iMac which I purchased in early 2013.

Followed the instructions.

rebooted.

renamed my computer back to what it was.

re-enabled my networking.

Problem apparently solved.

Oddly this fixed 2 issues for me.

For more than a year, my Rocket Stor USB drive has been repeatedly saying the Disk was not ejected properly.

And seemingly a separate issue, all email from my dad has been coming up as "Junk" but still in my inbox.

I have tried all kinds of things for making his email not come up as "Junk"

This process that you put forth of moving the "SystemConfiguration" Folder has unexpectedly fixed certain mail always being marked as "Junk" no matter if the sender was in my contacts or no matter how many times I marked the mail as "not Junk"

Thanks for the fix. And thanks for the bonus Fix.

Hi,

This is not quite right as you cannot just pull that folder to the desktop, for one it copies it by default, and 2 it contains boot.plist which cannot be deleted. So this needs editing.

I have had this issue for a very long time, it was fixed on my 27 iMac retina simply by installing Sierra as if my magic, but then this week I bought a brand new MacBook Pro 15 (with the silly touchbar) and did NOT restore it but set it up from brand new, and this issue has returned. I noticed it did it on screen saving or screen dimming, so disabling that so the screen never dims or saves seems to have stopped the issue.

I will try a corrected version of your list and report back if it fixes it or not.

Interesting.

I followed the steps and pulled it to my desktop.

I renamed the machine.

What is interesting was when I pulled up finder, all of my customization was gone so I had to start putting things back to the way things were.

Something definitely changed.

Perhaps one can pull the SystemConfiguration folder, but what it does is replace it with a default of some sort? Maybe this clears out some of the configuration files that are corrupted or at least are the ones which are causing folks problems with the Disk Ejection messages and in my case legit Mail showing up always as "Junk".

Anyhow. I am not sure it works for everyone or exactly how it works, but for me it was successful and maybe it will be for some others who are having perpetual problems as well.

Upgrading to Sierra would likely have fixed my issue as well especially with a clean install, but perhaps if I migrated the problem could have persisted as it did in Yosemite.

Anyhow... it would be great to hear how things go with your issues and how you fix them. Be sure an post your corrections and solutions.

Thanks

Sorry - did not solve the issue for me (did try twice!)
