The asterisk is “only upgrade if it won’t adversely impact mission-critical apps such as those for safety of life, health, etc.”. However, there comes an a very prominent asterisk with that I don’t bother to tell most about because most people will take that asterisk and misinterpret it. Note that I encourage most people that if your device supports the latest and greatest to upgrade for security, stability, and usability reasons. I don’t know how Apple thought that forcing 64-bit on Mac and dropping all traces of 32 bit support would be even a viable option because some people (myself included) are “edge cases” and still rely on 32-bit software where the manufacturer either has gone out of business or is refusing to recode their app. I unfortunately cannot move to the latest 10.15 Catalina because of the fact that my medical support software requires me to run 32 bit only and the company that makes the software is no longer in existence. I have found installer images for Yosemite moving forward and intend to download them all and keep them on standby just in case. The reason I am asking this is for my own sake does anyone know where to obtain an installer image for OS X 10.9 Mavericks? The reason I ask this is because I had to sit through about a six hour download process over 4G using Internet recovery to get the Mac back to factory and wiped from the previous owner.

Thankfully I know both people that previously owned it. This is a third hand Mac as I bought it off somebody who bought it off somebody else. I recently acquired a late 2013 MacBook Pro with the retina display.
