Running Snow Leopard on a Macbook, as of late it's been heating highly. Activity Monitor shows a process called "MDS" and it's taking up 161% of the CPU.

What can be done to stop this, I want to go with the safest way possible by the way.

Thanks in advance.

Re: MDS process causing Mac to overheat

The MDS process is the system process that handles Spotlight. It could be that Spotlight was indexing at the time. You should be able to safely quit the "MDS" process from Activity Monitor - all you're doing is "rebooting" Spotlight. Next time you click on Spotlight or do a "find" on your Mac, the process will again show up in Activity Monitor. If the problem keeps occurring, then something's wrong with Spotlight.
