Illustrator CS5 was the real problem for me and others have said InDesign CS5 is also a problem.

It doesnt save preferences like units (mm or pixels etc), the eyedropper tool will crash the program when sampling colour is gradients or raster images and on quitting the programs shuts down and crashes at the same time which might be why preferences arent saved.

Work, mail, photos etc need to be saved out so I can get everything up to date once back on Yo.

Thanks to apple adobe Ive lost nearly two days trying to make CS5 work on ELC and all the palaver of upgrading and then reverting back.

Os X Adobe Cc 2015 Ation Failed Upgrade To ELC

If you use CS5 dont upgrade to ELC until there is a clear announcement that the incompatibility is fixed.

I refuse to pay the extortionate fees charges by adobe for the subscriptions system.

If you start you are locked in and the minute you stop paying all your work is lost due to backward incompatibility and ELC didnt make it worth it either.

In any case, Id suggest making a bootable backup clone of your HD before upgrading.

Look through the various posts on this forum to see the problems others are having.

Illustrator CS5 is the big problem and Ive heard Indesign is also a problem but I dont use it so much.

As I said, I have CS5 installed on my computer and will never, repeat never, sign up for any monthly Adobe accounts in the Cloud, wherever their clouds happen to be.

Os X Adobe Cc 2015 Ation Failed Update Of Firefox

Another thing Ive just become aware of is the create PDF plugin that comes with Acrobat Pro (which appears in the browser menu and allows users to save a web page as a pdf document) has just been disabled by Firefox, my preferred browser, because it is no longer compatible with the newest update of Firefox.

I guess Ill just phase Adobe out of my applications as OSX and other updates render Adobes offerings obsolete.

My computer is crashing daily, sometimes twice daily and from what I read, its been recommended to upgrade the OS.

The only thing you can do is either, live with the problem, upgrade to their cloud service, or revert your OS back to a time when it was fully supported by Adobe.
