NSAlert replacement on Big Sur
If you dislike the redesigned NSAlert on Big Sur as much as I do (as well as countless other users and developers), then I recently found a github project for a much better replacement.
Here's a brief example:
As you can see, it restores the human-oriented design and layout of pre-Big Sur systems.
The original project is here:
It does require some changes to work properly:
Mainly, to make the window moveable, do the following in the -init method in NSCustomAlert.mm:
• Remove the NSWindowStyleMaskDocModalWindow mask
• add _panel.movableByWindowBackground = YES
Also, you'll need to change the font from Helvetica to systemFont... and adjust font sizes as needed. Once it's done it works perfectly.
Another small change:
In [self expandButtonSize:btn expandHorz:10.0f minWidth:75.0f] change 75 to 96 to make sure OK button is the same size as Cancel
I'm not sure that the developer still maintains the project. I left a feedback but he never responded.
I'm gradually replacing all alerts in my apps with this custom alert. I already had my own category of NSAlert so it was easy to add this class in a single place.
These two files from the entire project are sufficient to display the alert: NSCustomAlert.h and NSCustomAlert.mm. I'm not using any other files.
The project doesn't support the "don't show again button" - but I never used it anyway.
Hope it's useful - if you have any questions let me know.
