My Gear: iMac (Retina 5K, 27-inch, Late 2015) Processor: 3.2 GHz Intel Core i5 Memory: 16 GB 1867 MHz DDR3 Graphics Card: AMD Radeon R9 M380 2048 MB

iOS: High Sierra 10.13.6

Preferences: The programs that are problematic are enabled. Only Photoshop works.

Problem: I have been running CS5 for quite a few years now, relatively trouble free other than some minor quirks.

Primarily, I use Photoshop, Illustrator, Acrobat Pro, InDesign.

Yesterday, everything but Photoshop all suddenly came to a crashing halt. Cannot start up the programs again. A long time ago, I turned off all auto updates.

What changed? Why, out of the blue, would all these Adobe programs just stop working?

Any help is greatly appreciated.

    CS5 really isn't supported beyond El Capitan. People have managed to keep it limping along until Sierra, but High Sierra's APFS & lack of support for legacy Java is really going to make life difficult. Maybe see blog.conradchavez.com/2017/09/25/… for some hints, but be prepared to either roll back your OS, or invest in current versions.

  • Thank you for that link. Greatly appreciated. I am currently waiting a Cable from Amazon so I can try a recovery from my MacBook Pro. I used to be an Authorized Apple Dealer and Adobe reseller. I cannot stand, with every breath in my body, Adobe. Garbage company based on that experience. Classic, greedy sleazy big company. They will never get another dime from me. If I have to, will regress OS. It worked fine for years, just stopped out of the blue. Hoping to reinstall older backup, may set it right again.

  • Here is the kicker .... APPLE, in their infinite wisdom.... has made it virtually impossible to roll back! I will be honest, I am totally disgusted by APPLE! Why? I purchased their computer and I fully EXPECT THE RIGHT To CHOOSE WHICH OS I USE ESPECIALLY THE ONE I PURCHASED WITH THE SYSTEM!!! Why do I have to struggle to make a boot disc of the system I was using?!?!?!!!! I don’t need their support! I don’t want their support! I want to load MY OS OF CHOICE I PAID FOR WHEN I PURCHASED THE SYSTEM!!! End of story!

    Golden rules before any major update: 1) make sure all your mission critical software will run on it & 2) Make sure you can get back to the old OS if you find a blocker [this will involve a clone as well as Time Machine, in case of emergency]. You cannot blame Apple for your lack of foresight. Sorry, but life just doesn't work that way.

    1) Major OS upgrades do not happen on their own. Never have, never will. 2) Rather than ranting in here, which is doing little except keeping me amused, why not post a question on Ask Different, 'How do I get back to El Capitan?'

1 Answer 1


After paying $1800 at the time for Adobe Creative Suite CS5, I too have no desire to go to a cloud based "pay for play" software, especially during these uncertain financial times.

Have you tried having two hard drives which contain two different operating systems on them?

I have Mac OS 10.8.5 on one hard drive so that I can used Steinberg's Cubase version 6, and I have MAC OS 10.13.6 Hign Sierra on a my main hard drive - I just switch to my "downgrade" hard drive and keep working...and you can access both drives from the menu like normal.

That was my saving grace! I can still use Photoshop on 10.13.6, but it won't let me run Adobe Premiere CS5.

Sadly, in all my Mac years no one ever told me I could do that. It would've saved me a lot of upgrade money when a new OS didn't work with my audio software (especially WAVES plugins which I paid lots of money for and it became obsolete, since WAVES too is on a cloud-based-pay-to-play model)

Hope this helps.

  • You could also use a Virtual Machine: an OS running as an app inside your current OS.
