Frequently Asked Questions

Why does the VBA Editor cursor jump backward only on my M1 Mac?

This erratic cursor behavior is caused by a known compatibility bug between the Microsoft Excel VBA Editor and the ARM-based architecture of Apple Silicon (M1) chips. Intel-based Macs are not affected.

Will Microsoft fix the VBA editor bug on Apple Silicon?

Yes, but Microsoft relies heavily on user feedback to prioritize developer resources. Submitting a detailed report through the Help > Feedback menu in Excel increases visibility for a future software patch.

Can I disable auto-formatting in Excel Mac VBA to stop the jumping?

While you can adjust Editor Options in your VBA preferences to turn off Auto Syntax Check, the M1-specific spacing bug often overrides these settings. Waiting for an official software update remains the most reliable solution.
