Hi @Esteban Aleja22775736s6to,
We are sorry for the trouble. This is a known issue with Magic Mouse on Mac devices while working on Ai v26.4.1.
This issue appeared earlier in v26.1 and later got fixed in v26.2.1, but it has resurfaced again.
The product team is aware of the issue & they have identified the issue and currently working on a fix. I would request you to upvote this UserVoice for updates and stay tuned for the updates.
In the meantime, you may install the older version of Ai v26.3.1.
Thanks & Regards,
Anshul Saini
