Apple looks only at its own navel.
Does not respect those who develop applications without paying for Apple.
Many software that working fine, just crashed with the **** El Captain.
I'm already using, for example, thunderbird instead of the Mail and I am very satisfied.
Paragon and Tuxera are traditional software to read and write NTFS format and have always worked very well. With El Captain crashed.
And we are still forced to listen to stupid answer from Apple that you must use Apple's format.
My patience limit with Apple arrived at the end and I'm definitely migrating to Linux.
And I'm Apple user since 1986 !!! I've never seen such serious software problems. Just look at the Apple Store evaluation of users with all Apple applications.
