Some of you may have noticed that I did not post anything yesterday. That was because on Monday evening, I decided to upgrade the operating system of my MAC computer to the latest version called Catalina that was released in October 2019 and had got some pretty good reviews. Since the OS I had been using (El Capitan) was pretty old, I felt that I should upgrade since older software is more vulnerable to hacks.
It is a rule of thumb that any upgrade of an operating system will cause some disruptions and I was ready for that. What I did not expect was that the next 24 hours would be a nightmare. Lots of applications no longer worked, the email folders all disappeared, the calendar was wiped out, it would not sync with the phone or the iPad, and so on and so on. For someone like me who uses the computer during most of my waking hours, this was a real mess and I spent much of my time trying to fix things and recover some semblance of normalcy.
What was most troubling was that I had full backups on an external hard disk but when I tried to restore the old system using Apple’s proprietary backup system called Time Machine (something that I have done before and is usually simple and easy to do), Catalina would not let me even do that.
I finally had to take the computer to the Genius Bar in the Apple store to get out of Catalina, install an OS (Sierra) that was not as old as my former one and get all my stuff back. The Genius Bar woman said that they have had to deal with tons of issues like this because of Catalina.
I finally got all my stuff back late last evening.
So this is a warning in case any of you were thinking of upgrading to Catalina. Be very careful.
