Season 3 ended in May, but as the sun now stands fans will have to wait until some point in early 2020 for MacGyver Season 4.
The first three seasons of MacGyver all premiered in late September — 2016, 2017, and then 2018 — so you can’t blame fans for getting confused when September 2019 rolled around and there was no MacGyver Season 4.
Same deal for Criminal Minds’ final season, if you were searching the CBS schedule for it.
