A bug in the update checker in iStat Menus 2 is causing an issue where the update dialogue appears, even after Skip this version has been clicked.
We apologise for the issue. This was not the intended behaviour. If you’d like to stop the update checker from appearing now, we have a workaround.
Please delete /Library/Application Support/iStat local/iStat Menus Updater.app if you’d like to permanently disable the update checker.
