Semenya wrapped up her participation at the Gold Coast games with two gold medals having already won the women's 1,500m three days earlier.
South Africa's Caster Semenya competes in the woman's 800m final at Carrara Stadium during the 2018 Commonwealth Games on the Gold Coast, Australia, Friday, April 13.
The 27-year-old moved into the lead from the first bend and took the field through 400m in 58 seconds.
With the middle-distance double now complete at the Commonwealth Games, speculation will now turn to whether Semenya takes on a similar challenge at next year's World Championships, and then again at the Olympics two years later in Tokyo.
"Yeah I think for this four years that has been a target to double up each and every championship", Semenya said of the middle distance double. They both finished with silver.
Canada's Alysha Newman set a games record 4.75m to win the pole vault, with a mark 5cm higher than McCartney.

World championships silver medallist Joshua Cheptegei won Uganda's third 10,000m title in succession also in a Games record of 27:19.62, while England's Katatrina Johnson-Thompson won the heptathlon.
Elsewhere on the track, Olympic and world champion Conselsus Kipruto won the 3000m steeplechase so comfortably he had time to slow down, look back and urge his teammates on to secure a Kenyan cleansweep of the medals and still break the Games record.
"I've never done that before in my entire life - it was instinct", Hughes said of his dive. "I'm sick and exhausted of coming here.my mentality was rewrite the script - the Kenyans just come in here and do whatever they want and nobody tries to mess up their plans".
