Miller signed with the independent label Rostrum Records in July 2010, in the lead-up to his mixtape K.I.D.S. Rostrum president Benjy Grinberg met Miller while recording with Wiz Khalifa at ID Labs.
Although Grinberg started giving Miller advice, he did not show interest in getting involved with his career until Miller began work on K.I.D.S., when he "noticed a maturation in his sound and approach to his music."
By that point, Miller had started attracting interest from other record companies, but chose Rostrum due to its location in his hometown and association with Wiz Khalifa.
K.I.D.S. was released by Rostrum in August 2010.
During this time, Miller broke through with a focus on social media engagement, digital sales, and persistent touring, due to a lack of radio airplay or mainstream features.

XXL featured Miller in its annual "Freshman Class" list of 2011, alongside ten other rappers including Kendrick Lamar and Meek Mill.
Miller released his fifth mixtape, Best Day Ever, in March 2011.
Its single "Donald Trump" became his first song to chart on the US Billboard Hot 100, peaking at number 75, and received a platinum certification from the Recording Industry Association of America (RIAA).
Also in March 2011, he released a six-track EP, On and On and Beyond.
Intended to target a new audience, four of its tracks were previously included on his mixtapes.
The EP was his first entry into the US Billboard 200 albums chart at number 55.

Miller's debut studio album, Blue Slide Park, released on November 8, 2011.
With 144,000 first week sales, it debuted atop the Billboard 200, the first independently distributed debut album to do so since Tha Dogg Pound's Dogg Food in 1995.
Three songs from the album, "Smile Back", "Frick Park Market", and "Party on Fifth Ave."
charted on the Billboard Hot 100, peaking at number 55, 60, and 64, respectively.
Blue Slide Park was certified gold in the United States and Canada.
Despite its impressive commercial performance, Blue Slide Park received a generally mixed critical response.

On March 23, 2012, Miller released his seventh mixtape, Macadelic.
The single "Loud" peaked at number 53 on the Billboard Hot 100.
In mid-2012, Miller premiered two songs produced by Pharrell Williams, from a planned collaboration EP, Pink Slime.
At least ten tracks were completed by August 2012 according to Miller, but the project was not released despite a multi-year effort.
Miller released an EP, You, under the alias Larry Lovestein & The Velvet Revival on November 21, 2012.
Rather than rap, the EP features Miller crooning over lounging jazz instrumentals.

In early 2013, Miller founded the record label imprint REMember Music, named after a deceased friend.
The label primarily focused on Pittsburgh artists, as well as releases for Miller's alter-egos.
Miller starred in a six-episode reality series, Mac Miller and the Most Dope Family, on MTV2.
It followed the production of his upcoming second studio album, and premiered on February 26, 2013.
On March 4, 2013, Miller released a mixtape, Run-On Sentences Vol.
1, solely featuring instrumentals made by himself, under his production alias Larry Fisherman.
Later that month, Miller featured on singer Ariana Grande's lead single "The Way" for her debut album, Yours Truly; the song is Miller's highest peak on the Billboard Hot 100 at number nine, and was certified triple platinum by the RIAA.

His second studio album, Watching Movies with the Sound Off, was released on June 18, 2013.
It received generally positive reviews, with most critics praising his new psychedelic sound.
The album debuted at number three on the Billboard 200, selling 102,000 copies in its first week.
The album spawned three singles; "S.D.S.", "Watching Movies" and "Goosebumpz".
The album featured guest appearances from Schoolboy Q, Ab-Soul, Earl Sweatshirt, Tyler, the Creator, Action Bronson and Jay Electronica.
According to Miller, the album is "very introspective and very personal so it's kind of throwing it all out there and seeing what happens."
