If you find any others that would prove useful or have information to share in this regard, please let me know.
I should point out that I have yet to install the new operating system. After my previous experience with the upgraded OS, I’m waiting a bit. But that doesn’t mean I may not upgrade tomorrow or when I have some time to spare. They say it can take an hour. But that depends on your machine and download speed, and the time it takes for you to back up your system.
