I use Opencore Legacy Patcher to run unsupported macOS on my older Macs. They used to have an excellent Reddit group that was easily searchable and rammed full of really good advice on how to fix common issues.
A couple of years ago they shuttered the group and moved everything over to Discord, and it’s been hell ever since trying to figure out how to fix something if it goes wrong.
You search for your issue, find someone talking about it, then have to pick through the dozens of replies either side to try and figure out if there’s anything useful. There are dedicated support threads now, but hardly anyone uses them, so they’re not helpful.
I really, really hate Discord as a support medium, and can’t for the life of me work out why the OCLP mods chose it over Reddit.
