Upgraded Mac Mini (Late 2012) to Catalina and now it acts like it is Buffering

[Anonymous]

Upgraded Mac Mini (Late 2012) to Catalina and now it acts like it is Buffering. I have Sketchbook Pro Version 8.7.1. When I was using Mojave I did not have an issue. I upgraded to Sketchbook Pro Version 8.7.1, before I upgraded to Catalina, and now it buffers while I am drawing. Any help would be appreciated!

I looked at the specs noted here:

https://everymac.com/systems/apple/mac_mini/specs/mac-mini-core-i5-2.5-late-2012-specs.html

It appears that the base model of the Mac Mini starts out at 4 GB of RAM and that is not a lot.  I suspect that the OS (Catalina) is using most of it and buffering the apps to HD memory.    NOTE:  The best option is to get at least  16 GB of RAM.

You have 2 options:

a. Revert back to Mojave (ideal) because it still supports 32 bit apps.

b. Get more RAM.

I have downloaded Mojave here:

Then used "Install Disk Creator" to make a bootable USB.

Once you install Mojave, you can use Time Machine to get your files back.  NOTE:  Again, I would "Manually" backup your files JUST IN CASE!!
