On December 17, Mack was named a starter for the 2020 Pro Bowl. Mack finished the season with 47 combined tackles (40 solo), 8.5 sacks, five forced fumbles, one fumble recovery, and four pass deflections in 16 games started.

Mack is an active Christian and spent much of his youth attending a church where his father and mother both served as deacons. Mack also enjoys spending time with his nieces, Malaysia, Maayana and Ma’kiyah, and counts his favorite film as Mary Poppins.

On September 1, 2018, following Mack's holdout through the entire preseason, the Raiders traded him, a 2020 second-round pick (Cole Kmet), and a conditional fifth-round draft pick in 2020 (condition failed, turned into a 2020 seventh-round pick) to the Chicago Bears for 2019 (24th overall, Josh Jacobs) and a 2020 first-round pick (19th overall, Damon Arnette), as well as 2019 sixth round pick (which was cycled through multiple trades, resulting in the Raiders selecting Trayvon Mullen, Isaiah Johnson, John Cominsky, Foster Moreau, and Quinton Bell and adding A.J. McCarron) and 2020 third round selections (Bryan Edwards). Shortly after the trade, Mack signed a six-year deal worth $141 million featuring $90 million guaranteed, becoming the highest-paid defender in NFL history.

On September 9, 2018, Mack made his Bears debut on Sunday Night Football against the Green Bay Packers. In the second quarter of the game, he sacked backup quarterback DeShone Kizer and stripped and recovered the ball. Later in the same quarter, he intercepted a pass from Kizer and returned it 27 yards for a touchdown. He became the first player since 1982 to record a sack, forced fumble, a fumble recovery, interception, and touchdown in one half. It was also his second time recording a sack, forced fumble, fumble recovery, interception and touchdown in a single game that dated back to week 12 of the 2016 season. In his second game with the Bears, Mack had four tackles and a strip-sack of Russell Wilson during Chicago's 24–17 Monday Night Football win over the Seattle Seahawks. Mack continued his excellent play in Week 3, recording a strip-sack of Josh Rosen in the 16–14 win over the Arizona Cardinals, the first player to record strip-sacks in three straight games since Mack himself did it in 2016. He had a strip-sack again the following week in a 48–10 win over the Tampa Bay Buccaneers. Mack became the first player to record sacks and forced fumbles in four straight games since the Indianapolis Colts' Robert Mathis in 2005. He is also the first player to record forced fumbles in the first four games of a season since the Jacksonville Jaguars' Tony Brackens in 1999. On October 4, Mack was named NFC Defensive Player of the Month for September. Mack is the first Bears player to win this award since cornerback Charles Tillman in October 2012.

On April 20, 2017, the Raiders picked up the fifth-year option on Mack's contract. Heading into his fourth season, Mack had his eyes set on the single season sack record. In week 2 against the New York Jets, Mack recorded his first sack of the season on Josh McCown during the 45–20 win. In week 3 against the Washington Redskins, Mack recorded a team high 9 tackles and sacked Kirk Cousins once during the 27–10 loss. In week 4 against the Denver Broncos, Mack sacked quarterback Trevor Siemian twice in during the 16–10 loss.

After the Raiders' Week 10 bye, he registered at least one sack in five consecutive games from Week 11 to 15. In week 13 against the New York Giants, Mack recorded a strip sack on Geno Smith and recovered the football during the 24–17 win. This was Mack's first forced fumble and fumble recovery of the season. In week 15 against the Dallas Cowboys, Mack sacked Dak Prescott twice during the 20–17 loss. On December 19, 2017, Mack was named to his third straight Pro Bowl.

Mack fininished the 2017 season with 78 combined tackles (61 solo), 10.5 sacks, one forced fumble, one fumble recovery, and three pass deflections in 16 games started. He was ranked 16th by his fellow players on the NFL Top 100 Players of 2018.

In 2017, Mack's younger brother, LeDarius, joined his alma mater, the University at Buffalo, after two years at ASA College in Miami. LeDarius joined his brother on the Bears as an undrafted free agent in 2020.

Mack finished the season with 77 combined tackles (57 solo), 15 sacks, two forced fumbles, and two pass deflections in 16 games started. After the conclusion of the season, Mack became the first player in NFL history to make the AP All-Pro First Team at two positions in the same year; right defensive end and outside linebacker. Mack was ranked 13th by his fellow players on the NFL Top 100 Players of 2016.

Mack was named the NFL Defensive Player of the Year for the 2016 season. In the 2016 season, Mack recorded 73 combined tackles (54 solo), 11 sacks, 5 forced fumbles, 3 fumble recoveries, 3 passes defended, and an interception returned for a touchdown. He was ranked 5th by his peers on the NFL Top 100 Players of 2017 as the highest-ranked defensive lineman. He was also named the professional winner of the Butkus Award.

Mack holds the all-time NCAA record for forced fumbles and is also tied for career tackles for loss in the NCAA. In 2015, he became the first player in NFL history to be selected first-team All-Pro at two different positions, defensive end and linebacker, in the same season. In 2018, Mack was traded to the Bears for two first-round draft picks and signed a six-year, US$ 141 million extension, becoming the highest-paid defensive player in NFL history at the time. He is widely recognized as one of the most dominant defensive players currently playing in the NFL.

In March 2015, the NFL amended the league's uniform numbering rules to allow linebackers to wear the numbers 40–49. As a result, Mack considered reverting from the number 52 to 46, the number he wore during his college career, but ultimately decided not to do so. In August 2015, Mack was named as the NFL's number one "making the leap" player. Before the start of the season, Mack shifted from linebacker to right defensive end, and played at both positions. In Week 3 against the Cleveland Browns, Mack recorded his first two sacks of the season on Josh McCown during the 27–20 win. In Week 13 against the Detroit Lions, Mack sacked Matthew Stafford twice during the 18–13 loss. In Week 14 against the Tennessee Titans, Mack recorded another two sacks on rookie quarterback Marcus Mariota during the 24–21 win.

Leading up to the 2014 NFL Draft, Mack was projected as a high first round pick in many mock drafts. He was selected with the fifth overall pick by the Oakland Raiders, making him the highest selected Buffalo player ever, and the first (and only) selected in the first round. Previously, the highest selected player from Buffalo was defensive tackle Gerry Philbin, who was selected with the 33rd overall by the New York Jets in 1964. Mack chose to switch from his college uniform number, 46, to 52 in order to comply with the NFL's numbering rules.

Starting all 13 games, Mack recorded 100 tackles including 19 tackles for loss, 10.5 sacks, three interceptions, one which he returned for a touchdown, and forced five fumbles. He won the CFPA Linebacker Trophy for the 2013 season, and he was named the 2013 MAC Defensive Player of the Year, becoming the first Bull to win the award in Buffalo's history within the MAC (1999–present). He was also named a second-team All-American by the Associated Press. Mack finished tied for first for the NCAA in career tackles for loss with 75 and set a new record for forced fumbles with 16. Buffalo's independent student newspaper, The Spectrum, also ranked Mack as the best Buffalo football player in the Division I history of the program.

After signing a four-year contract worth $18.67 million guaranteed, Mack made his NFL debut in Week 1 against the New York Jets, In the game, Mack recorded 6 tackles during the 19–14 loss. In Week 7 against the Arizona Cardinals, Mack recorded a season high 11 tackles during the 24–13 loss. In Week 11 against the San Diego Chargers, Mack recorded 5 tackles and his first career sack on Philip Rivers during the 13–6 loss. In Week 14 against the San Francisco 49ers, Mack sacked Colin Kaepernick twice during the 24–13 win. This was Mack's first game with multiple sacks in his career.

In week 8 against the Tampa Bay Buccaneers, Mack recorded a team high 7 tackles and sacked Jameis Winston twice during the 30–24 overtime win. In the following week's game against the Denver Broncos, Mack sacked Trevor Siemian twice with one of them being a strip sack which he also recovered.

On November 27, in a 35–32 victory over the Carolina Panthers in Week 12, Mack recorded his first career interception off of Panthers quarterback Cam Newton and returned it six yards for his first career touchdown. Mack also forced a fumble from Newton in the final minute of the game to seal the win for the Raiders. Mack finished the game with an interception, a sack, a forced fumble, a fumble recovery, and a defensive touchdown, making him the first player since former Raiders' cornerback Charles Woodson, who was with the Green Bay Packers at the time, in 2009 to do so. His performance earned him AFC Defensive Player of the Week for Week 12. Mack also earned AFC Defensive Player of the Month for November, registering four sacks, two forced fumbles, and an interception. In week 13 against the Buffalo Bills, Mack recorded a strip sack on Tyrod Taylor and recovered the football late in the fourth quarter to seal a 38–24 win. Mack helped lead the Raiders to their first playoff appearance since the 2002 season and was named to his second consecutive Pro Bowl and First Team All-Pro. In the Wild Card Round of the playoffs against the Houston Texans, Mack recorded a team high 11 tackles during the 27–14 loss.

During the Week 6 loss to the Miami Dolphins, Mack suffered a right ankle injury that resulted in him missing the first game of his career two weeks later against the New York Jets. Despite his absence, the Bears limited the Jets to 207 total yards, including just 57 rushing, as Chicago won 24–10. Mack also missed the following week's 41–9 victory over the Buffalo Bills before returning in Week 10 against the Detroit Lions; in the latter's 34–22 Bears win, he sacked Matthew Stafford twice.

During Week 11 against the Minnesota Vikings, Mack sacked quarterback Kirk Cousins once and forced a fumble from running back Dalvin Cook in the 25–20 win. Three games later, against the 11–1 Los Angeles Rams, he forced Jared Goff to fumble in a defensive effort that saw the Bears record four turnovers and win 15–6. During Week 15 against the Green Bay Packers, Mack sacked Aaron Rodgers 2.5 times and had two tackles for losses. On his half-sack, Mack was turned around backward by offensive lineman Jason Spriggs; unable to see Rodgers, Mack helped Bilal Nichols bring Rodgers down for a sack by using his back. The Bears won the game 24–17 and finished atop the NFC North while eliminating the Packers from postseason contention.

During Week 2 against the Denver Broncos, Mack recorded his first sack of the season on Joe Flacco as the Bears won 16–14. In the next game against the Washington Redskins, he sacked quarterback Case Keenum twice and forced two fumbles in a 31–15 road victory.

Mack continued where he left off in 2010, with a dominant sophomore season. Mack led the team in sacks, tackles for loss, and forced fumbles, on the way to being named first-team All-MAC. He recorded 64 total tackles, including 20 and a half for loss (third best in the nation), five and half sacks, one interception, two pass breakups, thirteen quarterback hurries, and five forced fumbles. Despite being suspended for the first game of the season following an altercation with teammate wide receiver Fred Lee, Mack set career highs in tackles (94), tackles for loss (21 - fourth in the nation), and sacks (8). He also recorded two pass breakups, four quarterback hurries, and four forced fumbles. He earned first team all-conference honors for the second consecutive season.

After redshirting as a freshman in 2009, Mack broke into the starting lineup and was one of the most productive defenders in the MAC. He totaled 68 tackles, including 14 and a half for loss, four and a half sacks, ten pass breakups, eight quarterback hurries, and two forced fumbles. He earned third team all-conference honors. He chose to wear the uniform number 46 as a motivational reminder that his true potential was not being recognized – 46 was the overall rating assigned to him (out of a maximum of 99) in EA Sports' college football video game, NCAA Football 11.

Mack finished the regular season with 47 combined tackles (37 solo), 12.5 sacks, six forced fumbles, two fumble recoveries, four pass deflections, and an interception returned for a touchdown in 14 games played with 13 starts; the 12.5 sacks were the most by a Bears player since Richard Dent in 1993. He was later selected to his fourth Pro Bowl and his third first-team All-Pro, though he did not participate in the former due to injury. He received an overall grade of 90.7 from Pro Football Focus in 2018, which ranked as the 2nd highest grade among all qualifying edge defenders. In June 2019, he received his second career pro Butkus Award.
