“IDC estimates that Apple sold 5.3 million Macs during the September quarter, which would be a 4% decline year over year from last year’s 5.51 million,” Chuck Jones writes for Forbes. “It would be the first quarter with a negative year over year growth rate since Apple’s September 2013 quarter. The 528,000 unit quarter to quarter increase would be the smallest since the September 2010 quarter.”

“Over the past four years the Mac unit increase from the June to September quarter has been 947,000; 903,000; 802,000 and 1.1 million,” Jones writes. “The percentage increases have been 24%, 22%, 22% and 25%. If IDC’s 5.3 million unit estimate is correct the percentage increase would only be 11%, at best half of what Apple has experienced since 2010.”

“I’m estimating that Apple sold 5.9 million units, up 23% year over year,” Jones writes. “At $1,200 per Mac Apple would generate $7 billion in revenue and about 14% of total revenue.”
