What version of InDesign? How was this upgrade done?
In place upgrade or clean install?
This was IN PLACE upgrade and current version number is Middle East Version 8.1 cs6
CS6 is not supported under El Capitan - best to either upgrade to CC 02014/2015 or revert to your previous OS.
Then you have two things going against you. The best advice I can give you is to roll back to your earlier operating system.
Yes i did that, Everything looks cool now..no complaint so far.
