Replace last two occurences of commas with dots
In each line in I want to replace last two commas with dots
I found such two sed piped method but it does not work with sed on MacOS
$ echo 'abc,def,12379,foo' | sed 's/(.*),/1./'|sed 's/(.*),/1./'
abc,def.12379.foo
Would there be a way which will work with any sed version? Not necessarily with sed only.

Can you add-eto the sed command? So like this:echo 'abc,def,12379,foo' | sed -e 's/(.*),/1./'|sed -e 's/(.*),/1./'.

Try this:
$ echo 'abc,def,12379,foo' | sed 's/,([^,]*),([^,]*)$/.1.2/'
abc,def.12379.foo
This will leave lines with a single comma alone (eg foo,bar). That may or may not be what you want.
(...) capture groups and 1, 2 backrerefences in the replacement string should be supported in all versions of sed; I've tested the above on Unix v7.
PS. Even the double sed from your question should work on MacOS; maybe your problem is that the lines are terminated by CarriageReturns instead of LineFeeds?

Using awk, treating the input as a set of comma-delimited fields, and joining the three last fields with dots,
echo 'abc,def,12379,foo' |
awk 'BEGIN { OFS=FS="," } { print $1, $2 "." $3 "." $4 }'
