External drive, bootable to Mavericks, 32 bit
In addition to my main drive, I have an external drive that is bootable to Mavericks. I have this set up so that I can run my still-functional Adobe CS 5.5.
Current OS on my main drive is 10.14.6 Mojave. If I upgrade to Catalina, will that have any effect on my external drive running 32-bit Adobe software. Wouldn't think so, but I thought I'd ask.
