It seems that this problem has been remedied during a recent OS update.

There seems to have been a problem with Mac key layouts for the following syllabics:

ᓂᐧ ᓄᐧ

ᖧᐧ ᖨᐧ ᖪᐧ ᖬᐧ

The issue is that after the sequence for any of these characters is typed, e.g. “n-w-i”, the next keystroke will produce a character before instead of after the syllabic.

Thus: “n-w-i-a” shows up as ᐊᓂᐧ instead of the correct result ᓂᐧᐊ, and “d-w-o-k-a” produces ᐠᖪᐧᐊ instead of the correct ᖪᐧᑲ.

To get around this, whenever typing any of the problem syllabics, use the “u” key to produce the w-dot: “n-i-u” for ᓂᐧ, “n-o-u” for ᓄᐧ, etc.

The source of this problem may be twofold
1) Each of the problem characters should have its own Unicode index, but does not.
2) The Mac keyboard compiler does not seem to allow two Unicode characters in a terminator.
