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I went to buy another Time Machine, but the locals only had outdated models formated for PC in stock.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 The only option is to use a newer version of the software.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

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
