My air conditioner died a few days ago and while it is a bit uncomfortable (I’m in Thailand and it is the hot season, so it gets up to around 34c in the office), it is insufferable to work when a 90 thread kernel process has 90% of the processor. It is really hard to troubleshoot a 90 thread kernel process when it is reporting as a single thread (and can't be killed, or the system dies).
For when your wifi breaks down and all you have is an ethernet port on your DSL, and a Mac Mini. Not so bad, but it does keep the fan running and eat up the processor. Good for short term (ship out the broken wifi router, get replacement).
I wanted to add an audio track to a video using the YouTube Video Editor. Apparently that is no longer a feature, or perhaps never was. (I seem to remember doing this in the past, but maybe not.) In any case, on OSX it is ridiculously annoying to do this simple task (merge an audio file with a video file).
NOTICE: the below was updated on 09-NOV-2014, though still a bit incomplete. Also what is needed is the list of plugins/extensions for the various browsers. Below is meant to help with new OSX installations. However, the list of what is included is out of date. For more recent lists, see: OSX Install - March 2016.
Back in the early 1990s I realized that most computers were misconfigured. Even today, nearly 20 years later, the otherwise well-engineered Apple products have not solved this problem. SSD drive-based Macs can particularly benefit from a half-dozen or so tweaks.
