Question: Radio/option button glitch in MacOS 10.13
I noticed this issue after updating my 2011 MacBook Pro to 10.13. The best way to illustrate the glitch was sharing a screenshot below. Basically the "unselected" state for radio buttons display as black squares. The "selected" state appears as intended. This issue is only apparent on my MacBook Pro, as my iMac doesn't have this issue.
On the latest OS version: 10.13.1
MacBook Pro (13-inch Early 2011), macOS High Sierra (10.13.1)
