refmac and related programs version 5.3 is available.
It is an intermediate version between 5 and 6. 
Details of new features will be available soon

Very big version for MacOS is also available. 

1) Program dimensioned with the following parameters.
MAXATOM = 80 000
MAXLINK =  1 000
MAXRESID= 5 000

It should be sufficient for most of the problems.
If your protein (including hydrogens) is bigger then you can resize the program:
change parameters in the include file atom_com.fh and recompile.

2) You must have ccp4 to compile/use refmac and related programs

Note: If you are downloading this version then you need to take the
dictionaries also. If you do so then you should do

setenv CLIBD_MON dictionary_directory/dic/

after ccp4.setup . Then you can run refmac and libcheck as usual.
