Starting over a month ago, my iMac Pro started locking up at various times and the cursor would disappear. I would have to use the power button to reboot the computer. That was the only way to recover from the problem.
I received an email from an unknown person saying that I needed to give him access to my iCloud account! I ignored it at first figuring it was a phishing scam, but he persisted and stated that he had purchased an Apple Watch from me on eBay and it was locked.
After a few days of review, I decided on the “Ambient Weather” WS-2000 weather station. This station came with a console that displayed the data and the console interfaces wirelessly with our wireless network to upload the data.
