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:
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
