macbook pro
It's hard to describe the noise, so here's a recording. https://www.youtube.com/watch?v=WDh-2qxeUGw&feature=youtu.be
My half-year-old retina MBP 13" started to make this clicking noise about once a second. The sound is very consistent, and just never stops. What is this, have you had it and how did you fix it?
The Apple repair folks won't actually replace the trackpad itself, but they will adjust the tensioner underneath the trackpad. I had the same issue in my brand new Macbook Pro, and they were able to solve the issue.
I've had this problem as well an posted this question which is very similar yours.
Here's my solution:
On the whole logic board you'll find tiny elastic sticks. They can be pushed a little. These sticks hold the aluminum bottom off the logic board and cause the disturbing mechanic noises that your are talking about.
Do not take any chances and apply insulating tape on every place of the aluminum bottom that the sticks can contact. Apply the tape again as it easily wears out.
Now, the Macbook Pro does not make any of the previous noises anymore.?
It feels like a solid aluminum brick on my lap.
And a close up...
This is what the back cover looked like when I was done. Uh, it's ugly! I'm glad it's on the inside.

The only moveable part in a retina macbook pro 13" is the fan as seen on the following picture: (courtesy of ifixit)
Therefore it must be an issue with the fan, particularly because the noise originates from the right side (imagine the macbook pro flipped and the fan will be on the right side). Either the fan failed or something got stuck in the fan and is preventing it from spinning. I suggest you take it into an Apple Store so they can have a look at it in detail.
