Found a solution folks:
I figured some things out after diving into the installer script, the way it works, and what it’s attempting to do. Once I realized some things I figured out a way to bypass the script. Here are written instructions below. It may seem like a lot, but if you focus on what’s in bold, it’s not so bad.
Everything worked out well, but when I launch the app it loads the splash screen but then turns into a java exec terminal screen with computer code. Also I am running the latest version of Big Sur
Thank you for reaching out to PowerSchool Community!
We would need to take a look at your settings to troubleshoot the issue further. We recommend connecting with the Designated Support Contact within your school district who should be able to work with the PowerSchool SIS Support team to see what is causing this issue.
I am not aware of who my "Designated Support Contact" is in the Simcoe County Secondary School Board. If you could let me know, that would be appreciated. Secondly, my board's IT support does not support Apple devices, so there cannot help me.
Designated Support Contacts are employees within each district who have the ability to work directly with the PowerSchool support team. There can be multiple Designated Support Contacts within each district. We recommend working with a school or district administrators to connect with the Designated Support Contacts within your district.
