CS5 is too old to run El Capitan reliably. Lots of problems with installation or problems like you've encountered. Of course, it will never be updated.
Yeah, figured as such. I did manage to get the old Library back after creating a new library, then quitting app and reopening, which brought the old and new back.
Good to know this.
The only real issue, and it's more of an annoyance, is text disappearing from text boxes, but reappearing after changing objects. Usually only part of a text block, and not often enough to be a real problem.
Could have been a lot worse. ;-) Otherwise, it's working okay.
And just a follow up, I think rather than a blanket, "It won't run reliably", it would be more helpful to users like myself, who need to keep it running for as long as we can, to know exactly what problems one might encounter and possible workarounds.
I just found that one workaround for the previous Library issue. By posting them, we can better help others with the same issues. Since these forum posts are easily found with Google searches, I'll continue to post my experiences as I continue to use CS5 with El Capitan.
That’s impossible to know.
It wasn’t tested so all bets are completely off. Some may have no issues; some may find it impossible to launch.
This is nothing new for Apple. They have zero regard for backward compatibility.
Actually, I've had quite good luck over the years with Apple OS's, but El Capitan was a bit of a departure. Still keep a legacy disk with 10.6.8 on it and you have to do a workaround to start back up in EC after using it.
Indesign has never been backwards compatible, but IDML has made it easier. I've been trying to use CS5 to work with 3 clients on CS4. Don't want to chance a CC doc back and forth, even keeping to the basics.
