Apple (AAPL) is first and foremost known for its iPhone, but its Mac business now accounts for roughly 11% of its yearly revenue. According to TrendForce, a global provider of market intelligence, MacBook shipments increased 17.1% during the second quarter.

9to5Mac, a news outlet covering all things Apple, reported TrendForce's findings.

The increase is largely being driven by sales of the updated 12-inch MacBook and has grown Apple's market share to 10% from 9.3%, gaining traction on ASUS for fourth place behind HP (HPQ) , Lenovo (LNVGY) , and Dell Technologies (DVMT) .

For the second quarter of 2017, HP came in first regarding market share related to Notebook brands with 23.4%. Lenovo's 20.1% market share earned it the second spot. Dell's 16.4% market share was good for third best. Apple along with ASUS each boast 10% market share, coming in fourth, according to MacRumors. 

That said, Apple's market share grew the second most from the first to the second quarter, trailing only Dell whose share increased 21.3% quarter-over-quarter. 

"The updated 12-inch MacBook helped expanded MacBook shipments by 17.1% from the first quarter to 3.98 million units. TrendForce also anticipates a double-digit sequential growth for third-quarter MacBook shipments as Apple will focus on the MacBook Pro series during the year's second half," according to TrendForce.
