Spotlight correctly interprets numerical expressions, but it also treats them as search queries for the entire filesystem, resulting in an expensive retrieval process after every keystroke. It's the most convenient, so I use it anyways, but the end result is that cpu starts to overheat for a query as simple as 1 + 2.

I turn everything except calculator (and settings menu) off, so this problem goes away.

I never really want to use spotlight to browse to some random directory or file on my filesystem, for me it's strictly for calculator and opening the Bluetooth settings...

Think Alfred may be more efficient here, since I've never noticed that issue at all.

Using Alfred (with powerpack) is like having gills while living underwater. It's hard to get the scuba divers of the world to switch since they are so invested in their myriad gear and it's so difficult to convey the value prop when you haven't experienced it.
