Resize Mac Partition is Disabled - how to partition properly I have two partitions on my mac book pro. One partition is running os Yosemite and other one is running bootcamp windows 8.1. Yosemite is 75GB and Bootcamp has 673GB. I shrinked the windows partition by and made 142 GB available, but that space is not available to the mac side and neither can I see it from Disk Utility. What is the proper way to increase my macintosh HD without loosing any data? I am not able to resize any partitions from the mac side.



diskutil list output:
Apple's tools won't shrink the Bootcamp partition, so you have several options:


get a third party tool to back up Bootcamp and/or shrink it outright 
install OS X on an external drive and run it there (basically punt)


There's a slight chance you have a siruation that could be remedied from he command line. Post the diskutil list details that Disk Utility doesn't show by default. Also, can you lose no data on Windows side? If you could delete that partition the side Mac could resize without any data loss.
