"stays in one spot" sometimes means the iMac is a target!
I have an iMac, set up for video/audio recording (now includes live-streaming), and have a small storage area for mics and cables, underneath the countertop where the iMac sits. I accidentally swung a mic cable XLR connector that "tapped" the iMac screen, leaving just that kind of chip on the edge of the screen (and unfortunately also cracked across the screen, as well). Stationary does not mean less vulnerable, if you have a brainless dolt carelessly swinging stuff around (that would be me!

)
