I'm on a 2011 MacBook Air running Yosemite (10.10.2).
Whenever I use Numbers (09), the machine grinds to a halt, and Activity Monitor shows that Numbers is using anywhere between 94-99% CPU.
This is even when I'm doing nothing at all in Numbers. Just trying to select a cell, for example I may wait 30 seconds or so. And this is on a simple spreadsheet with no real complexity.
What can I possibly check to troubleshoot this? Quitting, powering on and off, etc. have no effect. I also tried disconnecting from the internet, in case it was some issue about trying to connect. Again, no improvement.
Is there a log file which might show something?
The problem (I think) began with Mavericks. I hoped the recent Yosemite upgrade would resolve it, but if anything it's worse.
Any suggestions would be much appreciated. Thanks in advance.
