Description of issue

Version 1.4.7 of btop (latest at time of writing) crashes immediately on start after a single "flash" of screen, on MacOS Sequoia 15.7.4 with an M2 processor.

[1] 18753 abort btop

See aristocratos/btop#1716 for another with the same issue.

Running lldb, the abort is raised in Cpu::Draw

I tried to see if this exists in btop 1.4.6, but I couldn't figure out how to install an earlier version.

Can't reproduce on macOS 26 (M1) with btop 1.4.7. (The title says "1.4.7" but the body says "1.4.6" so it's not clear which version you're referring to exactly.)

[cHemingway]

Sorry, it was 1.4.7, I've edited the body now to correct it.

[p-linnane]

I can't reproduce this on macOS 27 (M3) with top 1.4.7 either.
