“Apple’s Mac operating system market share is up 35 percent year-over-year from October 2005 to October 2006. Data rounded to the nearest whole percent, actual rise is 34.6 percent,” Switch To A Mac reports.

Key Percent Increases

• Up 48.0 percent since April 2005 (Mac OS X Tiger launched April 29, 2005)
• Up 23.8 percent January to October 2006 – despite Intel transition
• Up 10.4 percent since September 2006

The October 2006 Key Percentages outpaced the growth reported for September 2006 which was as follows:

Included in the full article is an updated view of Apple’s Mac OS market share month by month for calender year 2006 up to and including October 2006. Switch To A Mac writes, “Pay careful attention to the numbers because Market Share splits Mac operating system data into two groups, Mac OS and MacIntel. MacIntel represents Intel builds of Mac OS X Tiger. Have a look at the October 2006 data. Mac OS is reported to have 4.09 percent of the operating system share while MacIntel is reported to have 1.12 percent operating system market share. When the numbers are combined, we get 5.21 percent.”

  1. An unusual way of expressing the statistic, albeit technically correct. However, a more neutral way of expressing the same statistics would have been to state that MacOS’s market share had increased by 1% over the time period, from 4.21% to 5.21%. Good news nonetheless, but not such a headline grabber.

    In other shocking news, recent reports suggest that 50% of the population have below average reading skills, a figure unchanged since records began.

  2. Hey Reality Check,

    I don’t see a problem with the headline. In fact, it’s an accurate way to describe growth. Besides, the investment community and Wall Street always talk about percent increase whenever the analyze year over year and quarter to quarter results.

    Anyway, this is great news for Apple.

  3. Well, if one’s overall marketshare increases from 4.21% to 5.21%, it’s not simply a 1% increase. It’s a “one percentage point” share increase, and there is a big difference between the two.

    It has nothing to do with being neutral or not, it has to do with being mathematically correct.

  4. SJR is correct. The way reported the data is also correct. It’s sad that people really don’t understand the difference between “percent” and “percent increase”

    If I had 10 jelly beans and I add 2 more, I’d have a total of 12 jelly beans. This represents a 20% increase.

    12 – 10 = 2
    2 / 10 = .2
    .2 * 100 = 20%

  5. You think you are so smart and then you make such a mistake:

    “In other shocking news, recent reports suggest that 50% of the population have below average reading skills, a figure unchanged since records began.” (Reality Check)

    While with some irony you want to show of your knowledge in statistics, you are actually wrong. Your joke does not work like this:

    Consider a sample of reading skills (1=worst, 5=best) like this:
    Average skill level: 28/7 = 4
    Percentage of population with below-average reading skills: 2/7, i.e. far less than 50%. In other words: Your joke does not work, because this percentage *does* fluctuate.

    The correct way to put such a joke is:
    “All car drivers in the US believe they drive better than average.”

    So, next time when you are trying to be a smart-ass, do it right.

  6. Dream on.

    The price we are paying to celebrate Apple’s market share in the single digits is too high.

    Apple’s products – software and hardware – are moving quickly and steadily toward average – latest examples: Mac’s worst ever upgrade: iTunes 7.0; new portables out of date upon release; MacPros disappointingly little performance improvement over PowerMacs; and, most prfoundly: customer care, customer service down the toilet; Apple arrogance at all time high.

    Pretty soon we will be fooling ourselves when we say Apple’s stuff is better than Microsoft’s stuff.

  7. Peterson – you may be correct that Apple’s quality control is going down because their volume is increasing. We will all have to keep an eye on that and make enough noise when QC is becoming a significant issue. It could be that Apple need some time to adjust to the increased demand for their products.

    Here’s a good example of Apple being overwhelmed to some extent. I took my 3 yr old PB in for a repair. The Genius at the Bar told me it could take up to a week to repair because they are really busy. They do the repairs at the store because Apple are swamped at their repair centers.

    Despite this, the mac was repaired within 3 working days, but unlike previous times they did not clean the screen or housing.

    The reality is that as Apple increase their market share, they will have to adjust how they check on their QC and how they provide customer support.

    Getting to 10 % US and 5 % market share will be a big deal for Apple. The former could happen within 12 months.
