'''MacWrite''' was the word processor on early Macintosh computers. It originally was released by Apple as one of the programs that came with a Macintosh, but was later spun off to Claris as a separate software product; this did not succeed in competition with other word processors, so it was eventually discontinued by the mid-1990s.<br />

== File identification ==<br />
<br />
The first two bytes of a MacWrite file are a [[Endianness|big-endian]] integer distinguishing MacWrite versions. MacWrite 2.2 used version 00 03 in this field.<br />
<br />
== Format details ==<br />
<br />
MacWrite 2.2 stored text in a compression scheme where the (language-specific) most common characters (for English, " etnroaisdlhcfp" in that order, with the space character first) were stored as one nybble each (half a byte), where the values 0 through E corresponded to the characters in the most-common list. The nybble value F signaled that a different character followed, meaning that characters not on the list took three nybbles (a byte and a half) to store. This usually averaged out to a savings, since the most common characters typically make up a high portion of the text.<br />
<br />
MacWrite 3.x and up used a different compression system, and were designed so files could be edited directly on disk without loading the entire file into memory.<br />
