Logi Options+ doesn't work at my side with the macOS 27 beta. While detecting hardware the app restarts constantly, and takes away the focus of whatever has the focus. Have uninstalled it, waiting for a fixed version.
I have installed macOS 27 beta on an external drive, perhaps that makes it difficult for Options+... although it works without problems on external drives with older macOS versions.
Update: the problem seems to be connecting Logitech keyboards to a Mac mini M4, connecting Logitech mouses seems to work fine. I tried these four keyboards, and all of them resulted a constant restarting of Options+: MX Keys Mini, MX Keys for Mac, MX Mechanical Mini, and Logitech Craft.
