Sir_Cutze When Excalibur after an update (1.2.7 -> 1.2.9) does not respond/open/shortcuts not working - try starting premiere and holding COMM+SHIFT and delete plug-in cache. Worked for me - Excalibur (1.2.9), PP25, OSX 14.7.4, intel mac pro 2019.
Sir_Ivan Sir_Cutze could you send me screenshot of Excalibur settings (commands tab). Are you not able to change shortcuts in Excalibur settings as well?
