Hello Yamei,

(Thank you Pavel)

Depends what you mean by "resolve."

In the plane sense of the word, probably the best thing you could do is keep throwing money at the XQuartz developers until they fix the issue. Until then Coot 0.9.x is dead on macOS Tahoe.

If, by "resolve" you mean "work-around" or "alternative" then Coot 1 is the answer.

There is a good chance that by the end of the month, Coot 1 and the Phenix gui will work nicely together (if they don't already).

Paul.

Hi Yamei,

This isn’t the most appropriate mailing list for your question. This topic has been discussed extensively on ccp4bb. What you explain rings the bell. Search ccp4bb archives -- the conversation was somewhere around past month.

Dear colleges,

I recently upgraded my system to macOS Tahoe Version 26.2 before noticing the warning: "Important: Do not upgrade to macOS Tahoe if you are using COOT 0.9. XQuartz fix is not yet available." Now COOT is no longer functional on my machine. Could anyone advise on how to resolve this issue?

Thank you so much!

All the best!

Yamei!
