小白的2014新款13寸macbook air开箱晒单迫于若干细心又较真的值友苦苦相逼，小白不得不修改下，把满篇因为懒惰而没有加上的m ac的os系统修改为苹果系统，英文不能瞎秀呀，央视都把NBA称为美职篮了，那我也就直白的苹果系统吧！我叫小白，也是新手小白，一直是什么值得买的忠实粉丝，看着大家精美的晒物图片一直是羡慕嫉妒的口水直流。
可是因为本人非常懒惰，又没有什么摄影技巧，所以也没好意思出来献丑，主要是觉得没什么可晒的商品，刚好今天mac到手随手拍了几张，这里献丑了。
其实我也不是什么果粉，只是怕麻烦的屌丝一枚，刚开始入手爱疯3gs的时候还觉得仿佛有那么点优越感，因为登陆qq的时候旁边有一个来自iphone客户端的标志略显逼格，也愿意刷机越狱的鼓捣，而现在公交车上拿最新款的iphone6也是越来越多啦，所以根本懒得鼓捣，但是电话还是选择爱疯只是因为它够简单又轻便。
入手过iphone系列3gs，4，5 s，ipad系列2和air，今天又迎来了macbook air，奥，对，还有两个ipod，早已不知道在哪里落灰呢！终于知道为什么上班这么多年没攒下钱的原因了，都买苹果了，略桑心言归正传，开始晒物。
13寸128g国行版本，信用卡分期十二期无手续费，还行吧，本来想买港行，可是还是有些不放心，毕竟某宝水太深，笔记本算大件电子设备了，还是谨慎些吧！Apple MacBook AirMD760CH/B 13.3英寸宽屏笔记本电脑¥6588京东下面开始上图啦!心太急，拆外包装纸箱的时候就没有拍照。
直接从包装盒开始吧。
一如所有苹果设备外包装一样，简洁、干净。
从图片也能看的出它惊人的纤薄程度。
侧面唯一的标识，显示身份。
背面各种设备信息，13寸屏幕，i5处理器，4GB内存，128G固态硬盘，国行，话说就这个价格来说配置真心一般，但是苹果就是苹果，工业设计无可比拟，卖的就是设计吧！打开包装盒盖，当当当当，主角登场，铝制外壳在灯光下泛出金属的光泽，被咬了一口的苹果在正中央吸引眼球。

Macos现在疯狂肆虐的电脑病毒几乎都是针对Windows的，由于MAC的架构与Windows不同，所以很少受到病毒的袭击。
MAC OSX操作系统界面非常独特，突出了形象的图标和人机对话(图形化的人机对话界面最初来自施乐公司的Palo Alto研究中心，苹果借鉴了其成果开发了自己的图形化界面，后来又被微软的Windows所借鉴并在Windows中广泛应用)。
苹果公司能够根据自己的技术标准生产电脑、自主开发相对应的操作系统，可见它的技术和实力非同一般。
打个比方，苹果公司就像是Dell和微软的联合体，在软硬件方面“才貌双全”。

THE FUTURE IS WHAT WE MAKE ITC7364B Duct TVOC SensorINSTALLATION INSTRUCTIONSThe TVOC sensor emulates the human perception of air quality much more than a CO 2 sensor and even detects odorless, potentially hazardous substances such as carbon monoxide.The CO 2-equivalent sensor output value was developed to allow the IAQ sensor to be used in select Demand Controlled Ventilation applications.Before InstallationRead these instructions carefully before installing and commissioning the transmitter. Failure to follow these instructions may result in product damage. Do not use in an explosive or hazardous environment, with combustible or flammable gases, as a safety or emergency stop device or in any other application where failure of the product could result in personal injury. Take electrostatic discharge precautions during installation and do not exceed the device ratings.NOTE 1: The air quality sensor requires a continuous calibration time of at least 3 weeks before the sensor algorithms provide accurate measurements. During this period the product-to-product readings may show large variations. The sensor may also indicate very high ppm readings during the initial calibration phase.NOTE 2: The air quality sensor is meant to provide an accurate measurement of INDOOR air quality. Diesel exhaust is not a component of indoor air quality and the sensor should not be used in such an application.MountingThe duct type sensor installs on the outside of a return air duct with the sampling tube inserted into the duct. Mount the sensor in an easily accessible location in a straight section of duct at least five feet from corners and other items that may cause disturbances in the air flow. Avoid areas with vibrations or rapid temperature changes.For proper function probe must be mounted with holes in probe aligned with air stream (sensor mounting holes oriented at 90 degrees relative to air stream)Drill a 7/8” or 1” hole in the duct at the preferredlocation and insert the probe into the hole to mark the enclosure mounting holes. Remove the unit and drill the two mounting holes. Clean all drilled holes of debris before mounting the device. Mount the enclosure to theduct with two #10 sheet metal screws (not included)such that the duct air flow is parallel with the vent holes in the probe (i.e.: air flows directly into the probe holes). To prevent air leaks, ensure the gasket is compressed around the probe between the device enclosure and the air duct. As shown in Figure 1.The enclosure has a hinged cover with a latch. Open the cover by pulling slightly on the latch on the bottom side of the enclosure and at the same time pulling on the cover, as illustrated in Figure 2.A 1/2” NPT threaded connection hole is provided in the left side of the enclosure. Screw the EMT connector or cable gland connector in until tight. See Figure 3. It is recommended that weatherproof conduit or cable gland fittings be used.Fig. 3. EMT ConnectionThis device has a half-wave type power supply so the power supply common is the same as the output signal common. Therefore, several devices may be connected to one power supply and the output signals all share the same signal common. Use caution when grounding the secondary of an AC transformer or when wiring multiple devices to ensure that the circuit ground point is the same on all devices and the controller.Ensure the controller Analog Input (AI) matches the TVOC voltage output signal type before power is applied. The voltage signals have a minimum loadrating. Follow the ratings in the Specification section or inaccurate readings may result.Connect the LINEAR output signal to a 0-5 or 0-10 Vdc analog input port on the controller as shown in Figure 6. The device is factory configured for 0-5 Vdc output signal but may be changed to 0-10 Vdc via the menu. Changing output signal may be done during set up of the device. This linear output signal represents to 0-2000 ppm CO 2-equivalent value.The ASO (Analog Stepped Output) output signal is a second voltage signal that represents the three air quality levels of GOOD, FAIR, and POOR. Each level may be set independently via the menu to any value between 0 and 10 Vdc. The factory default is GOOD = 2.5 V, FAIR = 5.0 V, and POOR = 7.5 V. This signal canDUCT TVOC SENSORWiring•Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment damage. Follow proper electrostatic discharge (ESD) handlingprocedures when installing the device or equipment damage may occur•Use 18-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used to supply inductive loads such as motors. Make all connections in accordance with national and local codes.• Connector layout is shown in Figure 5. Diagram shown includes all options. If option is not ordered, connector will not be present.•Connect the positive DC voltage or the hot side of the AC voltage to the terminal marked POWER. The power supply common is connected to the terminal marked COMMON as shown in Figure 6.•The device is reverse voltage protected and will not operate if connected backwards.Fig. 4.

See Figure 4.Fig. 6. WiringDUCT TVOC SENSORalso be connected to a controller analog input, or it can be connected directly to a 0-5 or 0-10 Vdc input of a damper actuator for direct ventilation control as shown in Figure 7. In this way, the Indoor Air Quality Sensor can be used as a stand-alone device. Since all steps are completely adjustable, the device can also drive a reverse acting actuator.The relay output available on the RELAY terminals. The relay output terminals are completely isolated from other connections and are NOT connected to the signal COMMON terminal as shown in Figure 8. This signal can be used to directly control an alarm, a ventilation fan or may be connected to a digital input of a Building Automation System for status monitoring. Respect the relay contact specification as listed in this document.Set-UpVerify that the TVOC sensor is properly wired and all connections are tight. Apply power to the device and note that the LCD will display the software versionnumber for a few seconds and then the device will enter Warm Up mode. The Warm Up mode will last for five minutes and the LCD will count down the time. This time is required to allow the device and sensor to reach normal operating temperature. After the five minutes has expired the device will enter normal operation and the LCD will indicate the TVOC status and ppm value.OperationIn normal operation, the TVOC sensor will detect a broad range of reducing gases such as CO and VOCs and translate the measurement into a parts per million (ppm) CO 2 equivalent value. This value is displayed on the LCD in either ppm or % as set in the menu. The air quality value is also displayed as either GOOD, FAIR or POOR and these values can also be set via the menu.The GOOD, FAIR and POOR air quality levels control the Analog Stepped Output (ASO) signal. The ASO output signal comprises of three independently set voltage levels that can be used to directly control a damper actuator for three positions. The levels are set via the menu and each level can be set anywhere from 0-10 Vdc. The GOOD, FAIR and POOR air quality levels will also be displayed on the tri-color front panel LED. The LED colors are displayed as GOOD = green, FAIR = blue and POOR = red. If required, the LED operation can be disabled via the menu.The air quality value is also sent to the LINEAR output as a 0-5 or 0-10 Vdc signal to represent the 0-2000 ppm CO 2 equivalent. This signal can interface to any voltage analog input for logging or control purposes.The linear output scaling and ASO operation is shown below. Note that the ASO GOOD/FAIR trip level = 1000 ppm and the FAIR/POOR trip level = 1500 ppm. The ASO output levels are GOOD = 2.5 V, FAIR = 5.0 V and POOR = 7.5 V.The normally open relay will close when the airquality exceeds a pre-set trip point. The trip point and hysteresis value can be programmed via the menu such that the relay closes when IAQ > Relay Setpoint and opens when IAQ < Relay Setpoint - Hysteresis. By default, the relay has a one minute minimum onand off time to prevent short cycling. This feature may be disabled via the menu. The menu may alsobe used to test the relay function. The relay can be used to control an alarm, fan directly or to signal a digital input.Fig. 7. ASO WiringFig. 8. Relay WiringASODUCT TVOC SENSOROther features and configuration are described in the Setup Menu section.NOTE: The air quality sensor requires a continuous burn-time of at least 3 weeks before the sensoralgorithms provide accurate measurements. During this period the product-to-product readings may show large variations. The sensor may also indicate very high PPM readings during the initial burn-in phase.The TVOC sensor is meant to provide an accurate measurements of INDOOR air quality. Diesel exhaust is not a component of indoor air quality and the sensor should not be used in such an application.MenuThe menu may be accessed any time after the initial warm-up period. The menu is controlled by using the three buttons on the PCB labeled UP, DOWN, and MENU. All values entered are saved in non-volatilememory and will be restored correctly in case of a power failure.The menu has several items as shown below. To enter the menu, press and release the <MENU> key while in normal operation. This will enter the User menu step 1, pressing the <MENU> key a second time advances to step 2. Each press of the <MENU> key advances the menu item. The <UP> and <DOWN> keys are used to make changes to program variables by scrollingthrough the available options. When a value is changed, use the <MENU> key to save it to memory and advance to the next menu item. Actual menu displays with the factory default value are shown.NOTE: If no keys are pressed for 2 minutes, the menu will automatically exit.IAQ Unit ppmThe LCD displays the IAQ sensor reading from 450-2000 ppm. Use<UP> or <DOWN> to change from ppm (default) to % for 0-100 % display. 0-100% = 450-2000 ppm.

正如预期，苹果公司在今年对旗下的产品进行了小幅更新。
除了iPhone，Mac产品也获得了最新的英特尔Haswell处理器。
与MacBook Air不同的是，iMac产品在一年前获得了全新的设计，所以2013版看起来依然诱人。
2013版iMac依然拥有21.5英寸和27英寸两种款式，延续了前作的超薄设计，升级了Haswell处理器以及NVIDIA显卡，并内置了更快的802.11 ac WIFI和PCIe SSD固态硬盘。
售价方面，依旧为1299美元(7949元人民币)和1799美元(11009元人民币)起，目前国内行货暂未上架，但是参考中国区苹果在线商店2012款iMac已经全部显示缺货的信息，相信2013版会很快上架。
那么下面，我们还是一起来看看2013版iMac的使用感受如何吧。
外观和感觉苹果iMac的整体设计，可以说是目前一体机产品中最为精湛的。
在去年，iMac得到了一个全新的设计，将之前厚重的屏幕机身缩减到5毫米，框架更加轻薄。
与MacBook Air 不同的是，iMac并非使用了一整块铝合金作为外壳，而是两块，但是你在产品上几乎看不到焊接的痕迹，所以不得不佩服苹果的工业设计能力。
总而言之，这是一款漂亮、精致的一体机，充满了苹果的风格。
接口方面，你可以在机身后面找到耳机、SDXC读卡器、四个USB 3.0、两个Thunderbolt 接口和一个以太网接口，十分全面。
另外，销售包装内依旧包含了无线键盘，你还可以选择Magic Mouse或是Magic Trackpad，如果两个都需要，则需要支付额外的费用。
在这里建议大家选择后者，能够实现更好的手势操作感受，而设计过于怪异的Magic Mouse，基本上无法长时间使用。
一些用户经常会向我们询问到底购买哪款尺寸的iMac更好，其实这完全取决于你的使用场合。
如果是在狭窄的办公环境，不妨选择21.5英寸;如果是在家中拥有充足空间，自然是27英寸。
显示和声音iMac屏幕分辨率分为两种，21.5英寸为1080P全高清，而27英寸版本则拥有更高的2560*1440分辨率。

Macbook air 2013安装windows7，解决鼠标键盘失灵问题的解决方法（集成USB3.0驱动的方法）2014-09-13 14:07 8817人阅读评论(0) 收藏举报Macbook air 2013安装windows7时，会出现在语言选择界面，键盘鼠标均失灵，或者在用户名界面，鼠标键盘失灵。
本文采用的是将USb3.0集成到Windows7的安装盘的方法。
本文为参考/read-htm-tid-6613405-page-1.html，并添加了自己的心得。
步骤；1、在Mac下，运行Bootcamp，执行第二和第三项，第一项不需要选。
原因见说明3。
说明：（1）如果选中第一和第二项，则将使用Win7安装盘的ISO，创建USB盘的Windows7安装盘，并将Bootcamp下载的驱动集成到该usb中。
（2）如果是将整个MAc只安装windows7，完全抹掉MAc，则只需第二项即可。
如果是同时保留Mac和Windows7，则需要使用第三项，进行硬盘分区。
（3）因本文采用的是将USB3的驱动集成到ISO中的方法，因此，如果你有USB的光驱，则第一项可以不需要做。
如果没有，需要使用USB的windows7安装盘，则可使用第一项制作USB格式的Win7安装盘，或者使用其他软件制作USB的安装盘。
但这个ISO必须为按下文所述的方法制作的集成USB3的驱动的ISO。
（4）Bootcamp 5只支持Windows 64，不支持32位的系统。
如需安装32位的Windows7，需要Bootcamp4。
2、完成后的U盘中，其中的bootcamp文件夹为驱动，$WinPEDriver$据说为windows启动时使用的驱动，所以在第一步时，如果选择Bootcamp中的第一步和第二步，则会该文件夹，网上有说使用第一步和第二步解决驱动问题的，但我试用了，没有成功。
最好将整个U盘备份，否则如果需要重装WIndows7 ，需要重新下载该驱动。
