Sleepy iMac G5 logs

Preamble

Following on from Sleepy iMac, where the A1058 iMac G5 was constantly sleeping due to overheating, I thought it would be a good idea to publish the logs (Applications>Utilities>Console>System logs).

Log files

These are some examples of the logs:

Log 1

Note the issues that VLC is having (mmco: unref short failure)

This log is a bit of a larger example and shows some different VLC issues.
