Yes, it seems ok as my FET works normally now. 
it may be just an accident.

Sorry for making inconvenience

(p.s. also sorry for accidentally delete the message which I said that the programs runs normally again after my macbook restarts)

FET 5.48.1 accidentally quit in MacOS (Big Sur 11.1)

After I load FET (5.48.1) application, it will quit itself when I press ↑ (uparrow)  or ↓  (downarrow) button.
However , it does not have any problem when I use the mouse to click the constraints / information.

Big thanks!

The version now is 5.30.2 . 

It worked smoothly.

This is the Mac OS excuteable version I have waited for almost a year   

Thanks Darren McDonald

I have tried to download the zip file from his site.
But it seems that the Mac OS X executable FET file is still version 5.27.8 (the same version released last year by yush)

Thanks a lot
I have tried the setting you suggested and the outcomes are what I want.
This software is really great!
It helped my timetable scheduling work a lot

Is it that I have to add the constraints  A1 & A2 (min. 2 days), A2 & A3 (min. 2 days), A1 & A2 (max. 3 days) and A2 & A3 (max. 3 days) at the same time?

If yes and all weights are set as 100%, then I may have possible combinations:
Day 1 + Day 3 + Day 5
Day 1 + Day 3 + Day 6
Day 1 + Day 4 + Day 6
Day 2 + Day 4 + Day 6

The outcomes I alslo accept are  (Day 1 + Day 2 + Day 4 / Day 1 + Day 2 + Day 5 / Day 1 + Day 3 + Day 4 / ... )

My school is running 6 day cycle (Day 1 - Day 6) with each day 9 periods.

There are some subjects (2 lessons per cycle) which cannot be conducted in 2 consecutive days (including Day 6 + Day 1).
I can set the constraints (min. day between = 2 and max. day between = 4) to get what I want.

However, there are some other subjects (3 lessons per cycle) which cannot be conducted in 3 consecutive days (including Day 5 + Day 6 + Day 1 / Day 6 + Day 1 + Day 2).
I would like to know if there are any good ways to set the constraints for this situation.

Thanks a lot~~
