Q: Read-Only File System after updating OSX

I just updated my iMac's OSX to 10.11.4, and now my FCPX project on an external drive keeps getting a "Read-Only File System" message!  Anybody else have this issue?  Wondering if I should roll-back my OS to the previous version, where I had no problems accessing my Library...

 

Advice?

iMac, OS X El Capitan (10.11.4)

    Get info (command+i) on your external Volume and check to see if the checkbox at the bottom of the window ("Ignore ownership on this Volume") is UN-checked.

    I looked in the Info window, but nothing appeared below "Sharing & Permissions: You can only read".  Is this a feature of the new update?

     

    I restored to my previous version of El Capitan and everything works again.

     

    Thanks for the info.

    Yeah, I was just using the Tuxera NTFS format that it came with. 

     

    I restored to previous version of El Capitan, and everything's working.  I'll look for another drive large enough to hold it all, format it with Mac OS, and transfer everything over before I update the OS again.

    OS X is able to read NTFS but needs third party software in order to be able to write to it. The El Capitan upgrade to OS X broke many of the third party NTFS software and need. so the third party NTFS software needed to be upgraded to work with El Capitan.

     

    For that reason plus the fact that many applications do work properly with NTFS even with up today third party NTFS software, I have always refused to have anything to do with disk drives that were format with NTFS.
