Filed under: Odds and ends, Snow Leopard
If you experienced some odd performance problems on your Snow Leopard-running Mac early this morning -- say, right around the time of the Daylight Saving 'fall back' -- you're apparently not alone. The Apple support boards are hopping with reports of 100% CPU spikes coinciding with the switchover to DST between 1 am and 2 am, mostly associated with having the menu bar clock enabled and/or having the clock automatic set feature turned on.
The workaround is apparently simple (if it hasn't already resolved itself after the cutover to DST); just turn off the menu bar clock in System Preferences for a moment, and the problem should go away. On the other hand, the philosophical question of whether a system version that was billed as having no major new user-facing features outside of improved performance and stability should have arrived with so many fascinating quirks... well, good thing we got an extra hour of sleep last night.
Thanks to Gordian and everyone who sent this in.
