Now that OS X 10.10 Yosemite is available as a free upgrade from the Mac App Store, you’re probably wondering how well your Adobe software and other Mac apps will run on it. Below is a summary of various reports I’ve read on Adobe.com and around the web. I’ll continue to update this article as I find out more. The good news is that upgrading to Yosemite seems to cause fewer compatibility challenges than some earlier OS X upgrades did.
Yosemite and current versions of Adobe software
Adobe FAQs: Adobe has published a tech note, Mac OS X Yosemite (10.10) compatibility FAQs. It contains links to additional information, so be sure to expand each of the FAQ questions on that page. On that page Adobe says “The latest versions of all Adobe CC products are compatible” and that no updates are required to run Adobe CC products on OS X 10.10 Yosemite.
The Adobe FAQ says “In our testing we have found no other significant issues with running Creative Cloud products with OS X Yosemite,” but with every OS X release something usually turns up. If I hear of any, I’ll add them to this article.
Upgrading to Yosemite with older Adobe software or from earlier versions of OS X
If you’re upgrading from OS X 10.9 Mavericks or OS X 10.8 Mountain Lion you probably won’t run into problems. But if you’re making a bigger jump from an earlier version of OS X, or from Adobe software earlier than CS6, you may find issues that affect your migration.
Note that CS2 applications, including Photoshop, were written for Macs with PowerPC CPUs. OS X 10.10 Yosemite only runs Intel CPU-compatible software, so Yosemite will not allow CS2 to run or install. Adobe CS3–CS5 applications might run, but those versions were not tested on Yosemite by Adobe.
Photoshop: The Photoshop team has published their own blog post about the OS X upgrade, Photoshop & Mac OSX 10.10 (Yosemite). In it they say that they tested Photoshop CS6 through Photoshop CC and found no issues. However, it has been discovered that the Yosemite installer might corrupt an existing Photoshop CS5 installation; if this happens reinstall Photoshop CS5 and then it should work.
In Photoshop CS6 in OS X 10.8 through 10.10, if you are having problems with keyboard shortcuts or brushes, especially with a Wacom tablet connected, you may need to install the “white window workaround” plug-in. Another suggestion from Adobe is to downgrade the Wacom tablet driver to version 6.38-2.
After Effects: The After Effects team has also published a blog post about Yosemite compatibility, After Effects good to go with Mac OSX v10.10 (Yosemite). In it they say that they tested After Effects CS6 through After Effects CC and found no issues.
An application won’t start: Two possible reasons for pre-CC versions to not launch in Yosemite are Java not being available, and having non-Adobe plug-ins that aren’t compatible with Yosemite. See the topics Java requirement below and Plug-ins above.
Java requirement: When launching some older Adobe software for the first time in OS X, OS X may say that a Java runtime needs to be installed. If a button is provided, click it; if not, download the Java installer provided by Apple and install that. Some users have reported that the Adobe launch issue is not fixed until you reboot a second time after the Java installation. Also, some report that earlier versions such as CS3 are not working with the latest version of Java (currently Java 8), but it does work if they install Java 6, which is provided by Apple in the link above.
Some are wary of Java security issues, but OS X won’t let some Adobe applications launch without it. In the case of Photoshop, Adobe says Photoshop doesn’t need Java at all, but OS X puts up the message anyway.
OS X Gatekeeper may prevent older Adobe software from starting: Gatekeeper is an Apple security feature (added in Mountain Lion) that helps protect you from running malicious applications. If you run Adobe software released before Gatekeeper, you should know what to do if Gatekeeper prevents Adobe software from starting. Adobe covers that in this tech note: Error “has not been signed by a recognized distributor” | Launch Adobe applications | Mac OS. The short answer is to bypass the error by right-clicking the application icon, then choose Open from the context menu.
Adobe software released after Gatekeeper was introduced properly conforms to Gatekeeper requirements, so no adjustments are needed for them.
Intel compatibility required: If your Adobe software is earlier than CS5, to run under Yosemite at all it must support Intel processors. After Apple switched to Intel-based Macs, Apple started phasing out support for running software based on the older PowerPC processors. Starting with Mac OS X 10.6 Snow Leopard, Mac OS X no longer runs PowerPC-based software. You’ll have to check compatibility for each of the Adobe applications you want to run; for example, Photoshop CS3 was the first version of Photoshop that ran on Intel-based Macs. But even if your software older than CS5 runs on Yosemite, it may still have other issues because OS X has changed a lot since then.
Upgrading from Mac OS X 10.6 or earlier: You may also want to read my blog post “Mac OS X 10.7 Lion: Will Adobe apps and other software work?”, so that you can also be up to date on the more dramatic changes that were introduced in Lion, such as the end of OS X support for PowerPC-based software.
General compatibility and info
To learn about OS X software compatibility of Mac software in general, a great resource is the Roaring Apps database. It lists OS X software and its reported compatibility with the last few versions of OS X. For mission-critical software, you should also check each company’s support website to verify that it works.
Wondering what Yosemite is all about? For the most in-depth Yosemite review you’ll probably find anywhere, read John Siracusa’s review at Ars Technica. As with every major release of OS X, Siracusa not only reviews the visible features that Apple promotes, but goes under the surface to explain changes to some of the underlying technologies in OS X and how they affect your Mac experience.
10-bit video displays: For many years, Photoshop users and other graphics professionals have wanted proper support for 10-bits-per-channel video displays on Macs. (This isn’t about the file format, but the data path to the video monitor.) While 10-bit-capable displays, graphics cards, cables, and software (such as Photoshop) have been ready for some time, Apple has not provided the necessary APIs to complete the chain. As far as I know, there is nothing in Yosemite or even the new Retina iMac to indicate that this has changed.
