It's macOS Sonoma version 14.4.1.

I changed how my files were stored post this lagging issue to see if it would help - it was previously stored on my iCloud but I changed it to my computer to see if it was a network issue but nothing helped.

Hi, yes I have just the basics active:

Endpoint

Midpoint 

Centre

Extension

Perpendicular

I think these constraints may be the reason for the lags.

Try to remove them all and don't use at all.

Do you see lags in this case?

EDIT:

Just thought: Do you really mean Geometric Constraints?
Maybe you're talking about object snaps?

Can you share one of your drawings in which you observe the lags?

I was talking about object snaps, my bad! Just deleted geometric constraints and nothing changed, still lagging as usual. I also tried using an external mouse to see if it was a trackpad issue but still lagging just as much. However, I used AUTOCAD on a separate computer and the drawings were fine? So it confirms that the issue is with my computer specifically and not the drawing. I'll attach a drawing anyways to see if I'm missing something. 

Hi @mmi11s ,

There is nothing special in your drawing. I used AUDIT command and it found 15 errors in the drawing database, but I'm not sure that these errors could affect AutoCAD performance.

Do you use external references? I see one Xref, but it is unreferenced (= erased).

>>>Everything was working smoothly up until last week.

Can you remember what happened during this time on your Mac?
