Five years ago today, after listening to some negative discussion on @atpfm@mastodon.social, someone on Twitter angrily predicted that “in 5 years, Tesla will have a marketcap at least 5 times larger than Apple.” I made a calendar event for this prediction, because I am petty. But now the account that posted it has deleted all its tweets, ruining the fun.

When the headphones and the laptop cost about the same amount…

The A18 Pro in the MacBook Neo is 19% faster than the M2 Ultra in the Mac Pro in single-core performance (Geekbench 6).

The MacBook Neo starts at $599.

The Mac Pro, which is still for sale, starts at $6,999.

Dianna Cowern (aka Physics Girl on YouTube, and possibly @dianna@mastodon.social) has been fighting COVID-induced ME/CFS since 2022. She just posted her first video in three years:

Does Apple still not have any official accounts on Mastodon (or Bluesky)? Are they really still using X as their primary (only?) text-based social media platform? https://www.macrumors.com/2026/02/26/apple-teases-a-big-week-ahead/

Apple folks, please take a look at FB21375029, which is a regression in macOS 26.2 and later (including the 26.3 beta) that causes .glassEffect() to stop working in floating NSWindows. It works correctly in 26.0 and 26.1. I had to make a demo video because it doesn't show up in screenshots! (Please forgive the bad audio.) Sample project: https://github.com/siracusa/GlassEffectTest
