A quick trip to Canon’s website was not encouraging.
Having learned from last year’s snafu, I updated only the MacPro in the post production suite. The notice came this morning in the form of a banner on my MacPro. It took Canon a month to officially release the fix. Last year at this time the move to Yosemite from Mavericks caused consternation among Canon photographers who relied on the EOS Utility as I reported last November first here on Photofocus. Yosemite bows out as El Capitan takes the stage.
