'''eMac'''（為「education Mac」教育用電腦的簡稱）是由[[蘋果公司]]推出的[[麥金塔]]桌上型電腦。與蘋果第二代的[[iMac]]相比，本產品的售價較低，是為了[[教育]]市場的需求而設計。eMac的設計與第一代的iMac電腦類似，將螢幕、主機、光碟機、揚聲器等裝置組合在一起，成為稱作「[[一體機|all-in-one]]」的整體設計。eMac使用了[[PowerPC G4]]處理器，和舊款iMac所使用的[[PowerPC G3]]處理器相比要快上許多，[[显示器|螢幕]]的尺寸也加大為17吋。<br />
<br />
蘋果公司於2006年7月5日宣佈eMac正式停止生產，並由僅針對教育機構販售的低階版iMac取代，隨後在2006年9月這款低階iMac也對一般消費者公開販售。<br />
<br />
eMac也是最後一款搭載[[阴极射线管|CRT]]螢幕的[[麥金塔]]桌上型電腦產品。<br />
<br />
== 概要 ==<br />
[[蘋果公司]]在2002年4月首次推出eMac，定位為有別於新款[[液晶螢幕]][[iMac]]的低價麥金塔電腦產品。原本預計僅針對教育採購者販售，但蘋果公司在一個月後認為產品的品質已經達到一定水準，決定也開放一般消費者購買。<br />
<br />
eMac配有17吋的平面[[阴极射线管]]（CRT）1280*960 解析度 75 Hz 的顯示器、[[飛思卡爾]]（Freescale）生產的[[PowerPC G4]]處理器，以700或800MHz運行、[[NVIDIA]] [[GeForce 2]] MX顯示卡，以及內建18[[瓦特]]的立體聲喇叭。開放一般大眾購買的版本售價為1,099和1,499[[美元]]，這個售價剛好填補了舊款[[iMac]] G3的799美元與新款iMac G4的1,499美元之間的價格空隙。蘋果公司在2003年5月宣佈停止生產舊款的iMac產品，但一直未推出低價的麥金塔電腦產品，直到eMac推出為止。之後eMac推出升級版本，將[[中央處理器|處理器]]提升至800和1000兆赫兹，並將顯示卡更換為[[ATI技術公司|ATI]] [[Radeon]] 7500。<!--<br />
<br />
The eMac was further improved in [[October 2003]], when the 800 [[Megahertz|MHz]] model was eliminated and the 1 [[Gigahertz|GHz]] model brought down to its price. A more expensive 1 [[Gigahertz|GHz]] model that included the [[Apple Computer|Apple]] [[SuperDrive]] was also made cheaper. This model was notable for being one of the least expensive brand-name [[computer]]s at the time that could burn [[DVD]]s. The next revision to the eMac line came in [[April 2004]], with [[DDR SDRAM]], a faster [[Central processing unit|CPU]] running at 1.25 [[Gigahertz|GHz]], and a better ATI [[Radeon R200|Radeon 9200]] video card. The most recent revision came in [[May 2005]], with an even faster CPU running at 1.42 [[Gigahertz|GHz]], improved graphics and larger standard [[hard disk]]s. To Apple's detriment, a number of eMac machines have suffered from what was known as "Raster Shift", a strange phenomenon where the bottom third or half of the screen goes black, with the rest of image shifting upward and out of the top boundary of the display. Serious static also accompanies the problem, rendering the viewable part of the screen virtually useless. In response to the problem, Apple offered a solution which involved the replacement of a video cable inside the eMac's case. <br />
<br />
On [[October 12]], [[2005]], Apple once again restricted sales of the eMac to educational institutions and returned to its "E is for Education" marketing scheme that had been attached to the product from the original restriction to education buyers. The company re-implemented this restrictive measure for unspecified reasons. Some analysts believe Apple wanted to force the general public to purchase the more costly [[Mac mini]] or [[iMac]]. However, the eMac was still available for sale to the general public through some third-party retailer websites.<br />
<br />
In early 2006, some users started to experience system freezes in their Second Revision eMacs - by now around 18 months old. The fault was found to lay with a [[Capacitor plague|bad batch of capacitors]] which had also caused faults with the iMac G5, manufactured in a similar time frame. In June 2006 Apple introduced the eMac [http://www.apple.com/support/emac/repairextensionprogram/ Repair Program]. However, despite relating directly to the capacitor problem, the symptoms listed under the Repair Program do not include "freezing". Apple have agreed to extend the warranty -- for this failure only -- on any affected eMacs to 3 years.<br />
<br />
On [[July 5]], [[2006]], an "educational configuration" of the [[iMac]] Core Duo was introduced, discontinuing and replacing the entire eMac line. The new [[iMac]] has a Combo drive rather than a SuperDrive and a smaller hard disk of 80 GB.<br />
