For Operating Systems, Entrvst maintains a 3-Version Life-Cycle Support Policy.
We adhere to this life-cycle policy in order to keep our customers protected with the latest security updates.
We have discontinued support for OS X Yosemite.
You may use it at your own risk with a disadvantage of having a poor user experience and no support from Entrvst technicians.
We recommend upgrading to Mac OS High Sierra.
