Test your Mac again to see if the behaviour has changed.use your Mac for a day and see if your internet speeds drop over time) Let go of the Shift key when you see the login window (NOTE: If you have FileVault enabled you may need to log in twice).Immediately press the Shift key and keep it down.Not only can you test to see if the problem is replicated in Safe Mode, but the very act of booting into Safe Mode will run some checks, delete system cache files, verify your startup disk, and attempt to repair directory issues (if any are identified).įollow these steps to boot your Mac into Safe Mode: You've already done an excellent job of trying to get to the bottom of this, but there's a few things you haven't mentioned trying as part of your troubleshooting process.
#Faster internet speed for mac code
Unloading the kext removes the buggy code from the kernel, so that it doesn't affect performance.Īs you've found, troubleshooting is a process of elimination and often requires patience.
The provided extension is buggy and performance drops over time (maybe it keeps a list of something, and as that list grows, the length of time taken to scan the list increases, so the time to process a packet increases, leading to a drop in throughput?) In this case, the pulse client included a kernel extension which provides firewall functionality by inspecting packets as they pass through the kernel. Running within the kernel can give performance improvements for certain applications, and also access to APIs that aren't available to normal (user space) programs.
#Faster internet speed for mac upgrade
If your VPN security policy requires "Lock Down Mode" or "Traffic Enforcement", you may need to downgrade instead of upgrade the client.įor future reference, you can view loaded non-apple kexts with: kextstat |grep -vi com.appleĪ kernel extension is a program that runs within the macOS kernel. I can connect to the vpn without the kext loaded, and speed is no longer tailing off. I upgraded to 9.0.3(1667) and the kext is no longer loaded by default. I was experiencing this problem with pulse secure 9.0.3(1599). Long term solution is to upgrade pulse secure client. Short term fix is to unload the extension, command copied from linked kb article: sudo kextunload /Library/Extensions/PulseSecureFirewall.kext
Unloading the kernel extension restored speed without a reboot. In my case this was caused by the Juniper/ Pulse Secure VPN client's kernel extension, which was active even when not connected to the VPN.
