All University Mac users are strongly advised to upgrade from OS X Yosemite operating system to macOS Sierra (v10.12.6), as soon as possible, as Yosemite is no longer supported by Apple. The upgrade will help to ensure that Macs have the latest security, features, and remain compatible with other University systems. I am a long time user of Quicken Mac 2007 and earlier back to 1999. Since I don’t like the later version for Mac and my current version can’t run under Mac OS Catalina, I’m looking for alternatives. Today I started testing a trial version of See Finance 2 Version 2.1.6 (1029), running on my MacBook Pro 2019 with Mac OS.

The OS X Yosemite was released to the public on October 16, 2014, after been announcing it on June 02, 2014 at WWDC 2014. The Apple Inc. Has added a number of improvements and new features to the Download Yosemite Installer so that many Mac users have already upgraded to it by now. It’s true that the Yosemite update is a bit older by now but, it is still the most famous and the often used.
Good question and might be answered depending on whether your 2015 is an early Macbook or later. If it's an early model and BEFORE OS X 10.11 was released, you should be able to install OS X Yosemite. For example, I purchased a refurbished early 2015 Macbook Pro Retina 13' that came with OS X El Capitan pre-installed. I booted it with a USB thumb drive with an OS X Yosemite installer, erased the drive and installed Yosemite.
So, one way to find out is to use a USB thumb drive with the OS X Yosemite installer and see if it will boot to the OS X Utilities menu and allow your to install Yosemite.

The link from D.Cohen specifically states, 'Your Mac is designed to work with compatible versions and builds of OS X. If you try to use a version or build of OS X that's not compatible with your Mac, your computer might behave unexpectedly.'. There is no reason why a user can not install an older version of OS X that is compatible with the Mac.
