It appears the latest Checkpoint VPN SecureClient for Mac OS X 10.4.7+ may cause problems by using a large amount of CPU time and a large chunk of memory.
After installing the latest Checkpoint VPN SecureClient for Mac, a process labeled “airport” may take up 90%+ of the CPU and a large amount of memory. When the Checkpoint client is uninstalled, the “airport” process returns to “normal”. This issue may only occur on Intel based Macs and can be monitored by watching the airport process (a sub process of the launchd process) using the Activity Monitor located in the utilities folder.
A possible fix is to uninstall and then reinstall the Checkpoint VPN SecureClient for Mac. To uninstall the SecureClient, open the “Applications” folder and then open the “Check Point SecureClient” folder, then click “Uninstall SecureClient”.
The problem has been reported on a few Mac help threads:
