I updated my mid-2014 MBP to Sonoma using OCLP last month from stock Big Sur. And then last week or the week before, Apple pushed Sonoma 14.4. OCLP also had updates related to 14.4, so I did both.
I had no issues, on either upgrade. No more issues than what the OCLP devs already know about, which to me are minor.
This MBP is certainly a little sluggish with Sonoma. But the 14.4 update didn’t make it any worse (or better). Honestly though, it was already sluggish for me on stock Big Sur (the last official version for this machine). Stock Catalina was the last version that ran very well for me. At this point, I’m only using this MBP mainly for web browsing and some basic productivity. I have my M3 Pro MBP and Windows gaming machine for more serious/taxing stuff.
Anyway, I had no issues with the latest update. tunetardis’ suggestion, if you’re worried, makes sense, too.
Fireflies/Lightning bugs. I remember there were so many in backyards in the summer, even in the suburbs.
Then they just kinda went away. Feel like I’m lucky if I even see a few a year.
