Hi Marcus
I like the way you're doing your troubleshooting. Very systematic. I don't use Mail myself, but it could be that the Mail database is corrupt. Google this, and see what you need to do to repair the database.

Cheers

Hi Rob and Ronni,
I ran Disk Doctor on my WD Time Machine backup disc.
Although it’s overloaded it seems OK.
Here is the resulting test message.
DiskDoctor
Repairing file system.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Checking multi-linked files.
Checking catalog hierarchy.
Checking extended attributes file.
Checking multi-linked directories.
Checking volume bitmap.
Checking volume information.
The volume My TIME MACHINE appears to be OK.
File system check exit code is 0.
Updating boot support partitions for the volume as required.
Operation successful.

Anyway I ejected the backup disc and disconnected it from the iMac. [I have ordered a 4TB Mac formatted WD backup disc. Meanwhile I will save important docs to thumbdrives.]

Activity Monitor read NC as using 0.1%CPU and it opened and closed correctly until I commenced using MAIL. So, ten minutes later it’s doing it again. 90% CPU, 600MB Memory, but refusing to respond.
Ten minutes later, the MAIL alerts appear again.
I have turned off Safari and with no web browser running NC is non responsive.
It’s Gotta be MAIL thay’s causing this.
I have to delete most of my INBOX and maybe the ARCHIVE.
OR Should I uninstall MAIL and reinstall it?
How to do this efficiently is my new question?
Cheers
Marcus

HI Marcus
Just a quick reply which may save guru Ronni some time. :-)

 1. You don't need a Time Capsule to run Time Machine (if I
    understood you correctly)
 2. Backing up lots of files to Dropbox may be OK in Singapore, but
    it isn't really an option in poor old Australia...
 3. I suspect that your backup disk (time machine or time capsule)
    may be having some problems. Look in Applications/ Utilities to
    find Disk Utility. Do a 'Repair Disk' on your backup drive and
    see what it says...
 4. If you buy a new external backup disk, you can certainly reformat
    it. Disk Utility is once again your friend.

Cheers
Rob

Hi Ronni, An update.

I deleted the issues you quoted from EtreCheck System report.

Then I ran it again and it redlines the backup WD Time Machine as not large enough.
This may well be an issue.

I went to buy another Time Machine, but the locals only had outdated models formated for PC in stock. Another issue maybe transfering files to DROPBOX. I mean the web product Dropbox, Inc.
This is a continuous process as is Backup.

Anyway, it takes some time…minutes before NC appears and then it refuses to respond.

I checked Activity Monitor and it stated NC was using 90% of CPU until all the Alerts appear and then +/- % CPU until I try to delete the Alerts then it’s Back to 90%.
I saved the Activity Monitor Stats if that’s any use.

I’m still thinking it could be a MAIL conflict.

When I log out and log in to my other Account, I have no trouble with Sierra or NC. There’s only 10 emails and no Backup or Dropbox on that account

Oh well, I will get another Time Machine HDrive and see if that sorts it out.

Do you think WD or Seagate are ok reformatted?

Cheers for now

Dear Ronni,
You have certainly given me a lot of great advice.
I'm going to follow it carefully, but it will take me a few days.
I will report back when done.
Thanks so much
Marcus

Ok Marcus,
I’ve had a look at your EtreCheck system report. The items that stand out I’ve indicated below. I also feel you need to check all your applications especially third party apps & plugins for updates.

CS2 applications were written for the PowerPC processors that ran older Macs. The last version of Mac OS X to run PowerPC software was OS X 10.6.8 Snow Leopard.

There is no way to run Adobe CS2 software on macOS 10.12 Sierra. The only option is to use a newer version of the software. *Startup Items:* <etrecheck://help/startupitems>ⓘ <etrecheck://help/startupitems>
AdobeVersionCueCS2: Path: /Library/StartupItems/AdobeVersionCueCS2
TuxeraNTFSUnmountHelper: Path: /Library/StartupItems/TuxeraNTFSUnmountHelper
Startup items no longer function in OS X Yosemite or later

Uninstall these startup items - Startup items are obsolete since OS X Yosemite

*Launch Agents:* <etrecheck://help/launchagents>ⓘ <etrecheck://help/launchagents> * [not loaded] *net.culater.SIMBL.Agent.plist (2016-03-25) *[Support]* <https://www.google.com/search?q=net.culater.SIMBL.Agent.plist+support+site:culater.net>

SIMBL needs to be uninstalled - EasySIMBL does not work anymore because of the System Integrity Protection introduced in El Capitan

Time Machine:
  Size of backup disk: Too small
  Backup size 1.00 TB < (Disk used 350.63 GB X 3)

Your iMac’s Macintosh HD is *2TB size* and you are backing up to a *1TB size drive*. Your Time Machine backup Drive should be at least 2 times the size of all the data you are backing up.

Time Machine requires that your destination volume have, as a bare minimum, 2 times the space occupied by the data you’re backing up. (That gives some extra space to store multiple versions of at least some files.) So, as a first pass, multiply the “Used” value you see in the Get Info window by 2 to find out the smallest partition size Time Machine can use.

You’ll be far better off setting aside *3 times the amount of space used on your disk for backups*.

The reason is simple: the more space Time Machine has to work with on the destination drive, the more backups it can store—and the farther back in time you can reach when you restore data.

My Time Machine backup of my MacBook Pro 1TB HD is to a 3TB Time Capsule drive and the backups go back to January 2012
