Safari Users:

Please note that MySpeed will not work with Safari on OS X 10.11 or 10.12 (Sierra) due to the new System Integrity Protection.  Unfortunately, Apple has made it impossible for any application like MySpeed to integrate with Safari without disabling this new System Integrity Protection.  Although we do not recommend disabling System Integrity Protection, you may do so at your own risk.  After disabling System Integrity Protection, you will need to re-install MySpeed v6.2 from the link above for MySpeed to be enabled for Safari.


Google Chrome v48+ Users:

Starting with v48 and later, Google Chrome is now ‘opting-in’ to Apple’s new System Integrity Protection on OS X 10.11 or 10.12 (Sierra), much like Safari does.  OS X 10.11 and 10.12 (Sierra) will prevent MySpeed from being able to interact with any application that is under the control of System Integrity Protection. There is nothing we can do about these changes from Apple and Google, and discussions with the Google Chrome team have not yielded any compromises.


Disable System Integrity Protection


The supported way to disable System Integrity Protection in those cases where it's truly necessary is to boot into the Recovery partition and turn System Integrity Protection off from there with the csrutil tool (ref: Apple Developer Forums).   See the "Disable System Integrity Protection" page on our site for full details.

Applies to: MySpeed for Mac Version Version 6
