Adobe Reader El Capitan Upgrade Your Applications

If you cant or dont want to upgrade your applications to current versions, you should delay upgrading to Catalina.

More information emerges over time, as Apple, Adobe, and other software developers test with the final public release and produce updates with fixes.

To make the best use of your time and mine, I dont repeat rumors and random anecdotes.

The longer youve been using a Mac, the trickier the macOS 10.15 Catalina upgrade may be, because major changes will block a lot of older software from working.

The Verge has good coverage of this in their article Why macOS Catalina is breaking so many apps, and what to do about it.

Those principles remain true for the macOS 10.15 Catalina upgrade.

For example, have a complete system backup that you know how to restore.

Before you upgrade, remember to check compatibility for everything installed on or connected to your computer.

That could include printers, graphics tablets, scanners, cameras, networking equipment, calibration equipment, backup software, diagnostic software, adapters, hubs, docks, and so on.

Published compatibility reports may be on test systems that dont have the same hardware and software you use.

If you must ensure complete compatibility with everything you use, run your own tests with macOS 10.15 Catalina on a separate system, such as an external drive with a Catalina test system installed.

You can expect that current versions of Mac software will be updated for full compatibility with macOS 10.15 Catalina, but previous versions probably wont.

For Adobe applications, that means you can expect the most recent Creative Cloud (CC) versions to be either already compatible or will be updated eventually.

But if you use an older version such as CS6 or earlier that Adobe no longer updates, any issues with Catalina will not be fixed.

This is no surprise, because Apple has been warning about the 32-bit cutoff for several years now.

To be compatible, an application and all of the components installed with it must be 64-bit compliant.

The Adobe article Why dont my Adobe apps work in macOS Catalina discusses 64-bit compatibility for Adobe applications on macOS.

It also includes a table of some Adobe applications that are still 32-bit, whether they are going to be updated, and suggested alternatives if they not going to be updated.

Among other things, its about the amount of memory an application can address at once.

Adobe posted similar letters to the Adobe Communuities for Photoshop, Lightroom Classic, Lightroom, Bridge, and Photoshop Elements.

Instead, it appears to be a response to the special challenges that users are experiencing when upgrading to macOS 10.15 Catalina without first checking their applications against the much stricter requirements that Apple has built into Catalina.

It sounds like many users are contacting Adobe about Catalina blocking their older Adobe applications from opening, particularly Photoshop CS6, the final non-subscription version.

Note that although Photoshop CS6 is 64-bit, 64-bit compatibility is not the only tightened requirement in Catalina.).
