Skype 5.8.0.1027 & Excessive CPU usage on Mountain Lion 10.8

[shamwich_]

Hi All,

Many have also seemingly reported this, however I'm attaching debug logs and detailed system info.

Skype is using 100-170% of my CPU (i7 2010) on my 17" MacBook Pro.

• Using the Retail Version of Mountain Lion 10.8
• Have tried several uninstall/re-installs of the latest Skype available (v5.8.0.1027)

The fans usually kick in after about 30-60 seconds without even initiating an IM or Call in Skype. This causes the mac to heat up rather rapidy.

Attached:

1. 'About My Mac' Info
2. Application Info (interesting says 32-bit?)
3. Screenshot of my Activity Monitor, showing the CPU usage
4. skydebug-20120814-1835.log
5. skydebug-20120814-1835.ui.log
6. skydebug-20120814-1835.log

Please let me know if I can provide any further info or if there are beta versions that I can try to test the problem further.

Thanks in advance.

Looks like they know about it, and are working on it....

Workaroud:
Quit Skype, then in your home directory, look for a folder called Library/Caches/com.skype.skype (Finder > Go > Go to folder > ~/Library/Caches/) and delete that folder then start Skype... cpu usage should be back to normal.

This has been a problem with Skype since about v2.4? in my experience.  The response I got was the Skype goes for the maximum quality sent video, and is continually checking.  Hence the drop outs & changes in video quality.  In my case that means starting a call on about 50% cpu, then usage creeps up to around 100%, drops back to 70%, back up to 100%.  But then I am on v2.8....

Hi - I have the same problem, to the point where I really don't want to use Skype any more. I tried your solution, but there was no com.skype item in Caches and I still have the excessive CPU usage. Any further suggestions?

Perfect—thanks asmokanu. That sorted things out for me!

You have to look in the library folder under your user profile.
In finder menu choose "Go" and press the option key to show the Library for you user profile.

1. close skype
2. open a terminal
3. type

cd ~/Library/caches/

sudo rm -d -v -r com.skype.skype

4. Enter your user password
5. run skype

repeat it again when skype to consume 100% CPU
