We have just issued a critical fix to Maple, MapleSim, and Maple Flow running on macOS.
We have heard from some users who were experiencing serious problems with doubled characters while using Maplesoft products on macOS, including these reports on MaplePrimes. Further investigation determined that these problems appear specifically on macOS 11 and macOS 12. I am happy to report that we have now corrected the problem, and a patch is available.
Anyone who uses macOS 11 or macOS 12 should install this update immediately. We also strongly recommend that all macOS users install this update, to avoid problems that may be triggered by future updates to your operating system.
To obtain this update:
For those who have experienced problems, we apologize for the inconvenience and thank you for your patience while we worked to find a solution.
