That’s surprising given how close you are to recreational use legalization. Here in Poland MM is legal but we don’t have any producers and get fair chunk from Germany (Aurora Deutschland, 420 Pharma).
At the same time medical marijuana business got so silly that you basically go to a website, fill out a form, pay ~€20 fee and get an e-prescription in a couple of hours. There’s been some ineffective attempts at cracking down on it in the past weeks that resulted in slight fee increase.
Look into OpenCore Legacy Patcher. I updated my GFs 2012 Air to Ventura and it’s running okay. A bit clunky around MacOS updates since you have to specifically run patcher again to get graphics acceleration again but otherwise fine. It’s definitely worth it for security updates.
