Hi arnoldfromriva,

I believe we need to proceed with an EtreCheck report. EtreCheck is a useful app to diagnose and identify issues, both hardware and software. It is trusted by many users. Please follow the steps outlined below:

Navigate to: https://etrecheck.com and get the free version of EtreCheckPro.
Download it. It is a free and trusted app. It is often recommended here on Apple Support Communities.
Open EtreCheck, and before running the report, be sure to check “Allow full Drive Access” at the bottom of the EtreCheckPro window.
Run the report, and put it in a post, as seen here - https://discussions.apple.com/docs/DOC-250000211. We will then examine the report for issues in your Mac.

Cheers,

Jack

Apple finished their review about 10 days ago. They checked hardware components- everything OK and then erased and re-installed the operating system and ran software for 24 hours- no problems found. They advised re-installing my software, e.g. MS office suite step wise to see what if any of it may be causing the problem. So, I first let computer sit for a while without re-installing anything to see if problem occurred - it didn't. Then I installed MS Office suite and that was OK.

But quite by accident I did discover that my external hard drive was apparently causing the problem which I was able to verify by disconnecting the hard drive when computer froze which immediately returned computer to normal operation.

Who woulda thought!!

Thanks for the advice. I am not quite ready for that as this is a new computer and I am waiting for apple to finish diagnosing the problem. Once done I will test and if problem persists i will do as you suggested

EtreCheck is 100% harmless and useful - just search for "EtreCheck" in the Apple Support Community and there are thousands upon thousands of positive posts about it.

What is Apple thinking the issue is?

SEAGATE Free Agent "GoFlex" drive. Interestingly it worked quite well with my older iMac and works OK intermittently on my current machine.

But since you mention the cable possibly being defective it brings to mind trouble I was having getting a secure connection recently on my older iMAC. It seemed the cable connection was erratic and I had to switch around to different ports until it stabilized. Maybe I should try a new cable?
