I was running CS5 with 10.10.4 on a 2011 17" MacBook Pro on which the logic board finally failed, an d Apple no longer sells replacement parts for older MacBook Pro. I bought a new one with Mojave, transferred all apps and data from back-up external hard drive, and now when I try to launch Photoshop, InDesign, or any apps in the CS, an error message appears saying I need to remove and re-install. But how can I re-install? I no longer have the original DMG files from the initial download. In any case, given the comments of others on this blog, the apps won't work on Mojave anyway. So, like many others, I've installed Affinity Photo and Publisher, which appear so far to be very well-thought-out apps. EXCEPT that it seems that the plans are for Publisher to eventually accept IDML files, but perhaps not INDD files, which all of mine are. Seems like Affinity may be shooting itself in the foot on this one, given the huge potential market base composed of those who have happily continued to work with CS4,5, and 6, and therefore have INDD files. Any news/comments?
