MirrorOp version 220.127.116.11 on the ThinkPad Fall 2018 NMU software images will fail when it is put in extended model. The failure will potentially render the hard drive unbootable and unreadable.
For this reason we HIGHLY RECOMMEND you update your MirrorOp application immediately following the steps for manually uninstalling the old version and installing the new version at Connecting a Projector Wirelessly Using MirrorOP.
PLEASE NOTE: If you run the MirrorOp version 18.104.22.168 application it will prompt you to update and it will try to update to version 22.214.171.124 but the prompts are hard to navigate using the window presented to you that can't be resized. This is why we recommend using the link above and follow the steps for manually uninstalling the old version before installing the new version of MirrorOp.
