How do I get old apps like Photoshop CS5 to work on macOS Mojave

On the weekend I upgraded my MacBook Pro to macOS Mojave. Things are mostly ok but I have some apps that no longer work. The one I’m most stressed about is Adobe Photoshop CS5. When I try to run it it refuses to open.

I've tried resetting NVRAM and running Disk Utility, but this didn’t resolve the issue.

Before I take the plunge to revert back to macOS High Sierra I thought I’d try my luck here.

Do any of you folks have any other suggestions for me to try first?

Welcome to Ask Different :) Can you check if Adobe Photoshop CS5 is listed under System Preferences app → Security & Privacy → Privacy?

The first thing I would try is changing the security and privacy settings in System Preferences. You can do this as follows:

Go to Apple > System Preferences…

Click on Security & Privacy

Select the Privacy tab at top right

In the lefthand pane select the Accessibility option

At bottom left of the window make sure the padlock is unlocked (if not, select it and enter your password)

In the list of apps on the right-hand side, make sure Photoshop and any of the other apps you’re having problems with are ticked

OPTIONAL: If any apps you’re having problems with are not listed, click on the + button under the list and navigate to the apps to select and add them to your list. Once done, then repeat Step 6

Make sure you lock the padlock again that you unlocked at Step 5

Quit and restart any apps you’ve just allowed to control your Mac (i.e. if they were already open)

Now try running Photoshop etc again to see if they work.

Can you add an explanation for why changing the Accessibility settings for this app works? I'm baffled as to why going to the settings for helping users with disabilities would help a photo-editing app work.

@user312788 Be advised, Mojave is the last version these apps will work in. 10.15 will completely remove 32 bit app support. When next year's major upgrade comes around, think carefully beforehand, and make a backup of the old OS.

Dec 8 '18 at 4:38

@Wowfunhappy Thanks for the reminder. :) This is good advice, although Adobe Photoshop CS5 can actually be installed as a 64-bit version. Regardless, I'm with you on this. Users going forward who don't want to opt-in to Adobe's subscription model will need to either not upgrade macOS, purchase Photoshop Elements (which for most users would probably suffice) or move to a non-Adobe product.

@Monomeeth Have you tested disabling 32bit execution by booting with the -no32exec boot flag? I don't have CS5, but I do have CS6, which is fully 64-bit except for some 32-bit helper applications. Presumably of these helpers, it won't work at all in -no32exec mode. It crashes instantly. :(

Our go-to for preserving valuable but obsolete software is to put it inside a virtual machine using Oracle Virtualbox or VMWare, that way you can use it on any system forever without worrying about it being broken by OS upgrades / hardware failure etc.

I find this even more impractical than reverting back to High Sierra. Running two versions of macOS at the same time is wildly wasteful of system resources and will slow down performance noticeably. It is also rather inconvenient when switching between apps when some are running in a virtual machine and some are running on the host.

Modern VM's on modern hardware are pretty high performance, I a often working inside 2 or 3 VM's on my machine for things like CAD and IDE's and there's no noticeable loss in performance - and shared folders, network drives, git repos etc. work across the VM's. Having enough RAM definitely helps but if you're using something like Photoshop professionally you should already have jammed all the RAM in.

@JohnU Performance has improved, but you are absolutely still losing performance. If you have a powerful machine to begin with, you might not notice. However, if you have a slower machine, or if you're on a laptop and want your battery to last, you'll notice a hit.
– Wowfunhappy
Dec 8 '18 at 4:40

Undoubtedly there will always be some overhead, but it's surprisingly low these days, and given the benefits of being able to preserve expensive / incompatible packages. It can be worth buying a complete high-spec machine to run the VM on if the alternative is "buy the new version for 10k+" or "lose business".
