End of report

Many thanks to all for your comments and suggestions. Decided to format and reinstall everything. All working well and I should be finished in about 3 days :-) Maybe not touched since Dec 2009 it was due?

Thanks again,

Bryan

Hi Sparkleberry,

Yes I downloaded and ran EtreCheck and followed instructions given by Dominic23 but nothing else was heard as you can see from the lack of follow-up.

Programmes running or could be running on the iMac are: (all latest updates)

OS High Sierra

Parallels Desktop 13 (I need it for Windows 10 Pro)

McAfee Pro

Adobe Elements 18

DxO Photo Lab, and other DxO programmes

Microsoft 365

Kindle and other minor apps

A few other dormant programmes until woken (rarely)

Many thanks for this advice but it is not just a WD Hard Drive. It is the WDMyDrive backup system which is a 100% backup, also an extra Time Machine backup and the system allows me to access files from my phone, iPad etc when out and about.

Thanks

Bryan

This went to me instead of you. Probably the full restore pain :-)

All now sorted and thanks for your help.

Kind regards

Bryan

Many thanks for your excellent advice, which I will follow.

The reason for using McAfee is simply because I am running Windows 10 Pro through Parallels Desktop on the same drive. I need Windows for my amateur radio interests, and ACCESS to run a QSL Bureau database for our Society. If it were not for these I would be 100% Mac. I can leave McAfee on the Windows 10 partition.

Having this extra OS and a number of programmes maybe the cause of the mess, or the fact that this has been running since December 2009.

I will remove the rubbish as you and others have recommended and if still there every hour or so, sometime a few times in 10 minutes, I will reformat and start over. Trouble is the re-installation of Windows 10 Pro and radio bits :-(

Many thanks to you, and everyone for advice and assistance given.

Kind regards

Bryan
