There is nothing coming close to /r/steroids on Lemmy. The reason that subreddit is so great is that the moderators there are very quick at deleting noob questions that are answered in the wiki, and will quickly call out anyone giving dangerous advice.
Even on reddit the competing subreddits like /r/PEDs and /r/testosterone are absolute garbage that probably got dozens of people killed from a heart attack or stroke at this point
Yes. I run PopOS and Hackintosh on my Thinkpad, use the new M4 Mac Mini as my main desktop (with hopes of Asahi Linux support in the future), and run unRAID on my completely overpowered Ryzen 5900x NAS, where I have a Win10 LTSC VM for the rare occasion I need to run software that only runs on x86 Windows.
I would prefer to only use Linux if I could, but MacOS is very competent and far superior to Windows in my opinion. I have never had any issues accessing my unRAID shares on it
