This news won’t be new. But Mavericks has shot holes in Adobe Lightroom 5 and Apple Aperture. Both were initially working for me after the update but recently things have gone astray. Lightroom 5 is dead. Booting up the application just launches the splash screen and then its just dead calm. Aperture boots, reads the libraries and allows external editing, but cannot export images; just the eternal wheel of death and today folders began graying out. Likewise Snapseed can’t export to the iPhoto library and can’t ‘save as’. The forums are alive with the sounds of disgruntled users. Today I had to resort to importing images from phone and card into iPhoto, exporting to the desktop and editing in Photoshop. I hope Santa has a fix by Xmas.
