If you are experiencing difficulties with Lightroom 5 not opening and Aperture not exporting images on OSX 10.9 here’s the fix if you have your Catalogs and Projects on external drives. Because of the new security measures / protocols you need to ensure that your external drives have read and write permissions for all users. After a lengthy discussion with a tech genius friend of mine this was the solution he offered and everything is fine now. Go to it.
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.
