1 Installed Catalina on a MacBook Pro 13.3" - Mid 2012
So i know that this Macbook does not support Catalina but I went ahead and install it. The installation had several glitches with the circle and cross but it did made it to the desktop. Got online without any issues.
I did not used the computer all weekend but when i turned on the computer, it did turned on but it stop charging then it completely shuts off then i will not turn back on nor charge at all. Can this be related to Catalina, what could have happened? Is there a way to turn back on and install back High Sierra? Please assist, thanks!

@uitadmin - I thought you had it working, if the system is not responding at all then that is more likely a hardware issue.
What is the color of the MagSafe chargers LED Green or Amber?

Neither green nor amber are showing up. I've tested with different chargers.
