I used my old Mac which showed me English when I browsed through Mac App Store. However, after I purchased my new Mac and ported all the data using Time Machine, the Mac App Store suddenly shows me Japanese for some reasons.
I use English in OS Settings and everything works fine except the Mac App Store. I live in Japan, which is likely the possible reason it shows me Japanese.
Why do Apple use the different language only on the Mac App Store? And how can I resolve the issue?
