-Part２- No solution for macOS Catalina 10.15 Time Machine

| Alaudae.JP

In the end, there still seems to be no way to resolve the crucial Time Machine problem with macOS Catalina 10.15 (as of 3:00 PM on October 14, 2019).

Apparently there are many people with symptoms similar to mine.
In Japanese sources, many of the keywords are related to affiliates, and it's a pain to keep searching, so I decided to back up my search using another method to ease my anxiety.

Well, I'm optimistic that it will be resolved in the next update.
However, although I am happy that the number of Mac users is increasing and the amount of information is increasing, it is also troubling that there are also more and more confusing sources.

For example, when I was searching for a solution to a problem with Time Machine, it seemed to be correct, but I felt that something was wrong.

"macOS Catalina is divided into a system volume and a user volume, so when performing a clean installation, delete the user volume and erase (initialize) the system volume."

Information...

It may be correct if you install on a partitioned HDD or SSD from the beginning, but if you don't use partitions, it's a waste of work, so if you want to clean install macOS Catalina, it's better to initialize the entire HDD or SSD to avoid confusion. I think.

To do this, go to the Disk Utility menu bar > View and use the
Show volumes only
Show all devices
method.

When selecting to display only volume

Show all devices

Rather than being taught, I feel like I've learned it out of necessity from experiencing many problems each time. Anyway, there are various ways to initialize it depending on how you use it.

There are also problems with the macOS Catalina mail app and messages disappearing.
Regarding this, I always read it directly from the backup and use it, so I guess I have a strong feeling about it now.

I'd probably be asked to explain in detail, but basically each person has a different way of using it, and even if I created one, it would just be used for other purposes, so I wouldn't do it.

While it's certainly easier than Mac OS X, upgrading or migrating to macOS is never safe or perfect. After all, a minimum amount of knowledge and information gathering is essential.
(If I had checked the source, I wouldn't have lost my macOS Mojave backup data)

However, backing up your data is not absolutely safe, so you need to take some measures to prevent data loss. After all, what does it mean to be easy and comfortable?
