x86_64 version of libncurses

[Sriranga Veeraraghavan]

Hi Murray,

Are you sure you downloaded the M1/ARM version of Sage?  

Based on the error message below, I’m guessing you may have accidentally downloaded the x86_64 DMG instead of the ARM64 DMG (they are both available on GitHub, with the ARM64 version being about 90MB smaller than the x86_64 version)

I just downloaded the ARM specific DMG for Sage 9.7 from GitHub and did not see this issue on my M1 MacBook Air:

Best,

-ranga
