A warning about Catalina and the 2019 Mac Pro

[Jim Curtis]

[Eric Santiago] “Hi Jim, the SuperDuper does a clean clone at all times? Do you overwrite the existing clone or go into iterations?”

Eric, full disclaimer: I know just enough of the technical side of computers to get my work done. I’m not a computer or IT expert, by any means. But, I’m a long-time Mac user.

Most of the time, I invoke the “Smart Update” in SuperDuper that only re-writes what hasn’t been changed since the last cloning. Every now and then, I will do an erase of the clone, and clone the entire boot disk. Why? Gambler’s Fallacy.

Should I have to do a complete restore of my internal drive contents, what I’d probably do is a clean install of OSX (It’s faster than it used to be under previous builds of OSX.), then migrate my apps and documents from the clone with Apple Migration Assistant.

However, in the past under prior OSX versions, I have wiped my internal boot disk and restored from SuperDuper, and the only issue was having to reauthorize some plug-ins. I always clone before doing an OS update.

“ALL Hardware from Apple shipping with Catalina Pre-installed will NOT be able to boot or run on macOS Systems prior to Catalina !!!!”

Exactly… Apple basic truths, goes back to my days as a Mac technician when the Intel cheesegrater came out: Macs cannot be used with an OS older than the one they have shipped with.
