Spotlight hung on OS X Yosemite with 100% CPU usage. I recently upgraded from OS X Mavericks to Yosemite, and all went well except for one thing: The mds processes were constantly taking 100% CPU, resulting in decreased system performance and decreased battery life.

Spotlight hung on OS X Yosemite with 100% CPU usage

Now I’ve been through this dance before, knowing full well that every OS X upgrade results in a Spotlight re-index to upgrade the Spotlight DB and pick up any new files. But in the past this re-index had taken at most an hour or two on my roughly 80% full 750GB SSD drive. But this time was different — Spotlight was running not for hours, but for days.

Fixing Skype’s High CPU Usage. I brought home a new MacBookPro the other day (well yesterday) It had nothing but a clean install of 10.7.2, I installed Skype, and did a bit of video calling, to my surprise it was using over 300% of the CPU. Unless if it is solving the cure to cancer, that should not happen. I tried multiple versions of the software, and they were all taking up the same amount of CPU cycles. f##king frustrating!

This was the before picture This is the after picture: The fix hack: I realized that Skype uses peer to peer with supernode peers for call routing. I enabled the Mac OSX Firewall, and disallowed incoming connections to Skype, so now I can video chat, and as well have the CPU stable at around 60% instead of 300+% Apple Power Supplies — Macbook Battery Chargers, Apple iPad Adapters.

Mac notebooks: About the Sudden Motion Sensor

These include: MacBook MacBook Pro MacBook Air PowerPC computers starting with PowerBook G4 (12-inch, 1.5GHz), PowerBook G4 (15-inch, 1.67/1.5GHz), PowerBook G4 (17-inch, 1.67GHz), and iBook G4 computers starting with iBook G4 (Mid 2005). Note: Computers with Solid State Drives (SSD) or Flash Storage do not use SMS as the drives have no moving parts. The Sudden Motion Sensor is designed to detect unusually strong vibrations, sudden changes in position, and accelerated movement. If the sensor detects any of these, it instantly parks the hard drive heads to help reduce the risk of damage to the hard drive in case of impact. When the SMS senses that the computer's position is once again stable, it unlocks the hard drive heads and returns to normal operation.

What if I need to disable the Sudden Motion Sensor? First determine the status of the Sudden Motion Sensor From the Finder's Go menu, choose Utilities.
