Why Am I Asked to Install Legacy Java SE 6 Runtime?

Photoshop provides its users with a host of new tools considerably improving their ability to create and edit both 2D and 3D files. The enhancements added to the performance, speed, and efficiency of the software package; therefore, it was universally acclaimed by technology critics. Most importantly, the software release was specifically designed to run on Intel processors of Macs without having to translate G-5 specific instructions with the help of the Rosetta layer.

These major functional improvements and simplified tab-based interface are appreciated by many users who don’t want to upgrade the graphics editor to the latest version. Unfortunately, the owners of Photoshop have noticed that the older versions of the software are not compatible with macOS High Sierra. Specifically, after updating their MacBooks and Mac desktops to High Sierra, they have been prompted to install the legacy Java 6 runtime. The question then arises, “How can it be done?” This article has been written to introduce owners of Photoshop to a simple method of installing the Java package, which will make possible the use of the graphics editor.

What Needs to Be Done?

Similarly to other apps such as PDF Studio or Visual Studio Code, Photoshop (for example, CS3) needs Java 6 in order to operate. The problem with compatibility is grounded in the fact that during the upgrade process to macOS High Sierra, Java can be uninstalled from a user’s computer. Another reason for the reemerging prompt to download legacy Java SE 6 runtime is that a system might already have one out of three Java 9 updates or even Java SE 10, which are incompatible with the old version of the famous Adobe product.

To run Photoshop CS3 on a Mac under macOS High Sierra, the legacy version of Java has to be installed. Once this is done, the graphics editor can be operated as usual. It has to be noted that the functionality of the required runtime software is no different from that of the following releases: 2013-005, 2014-001, 2015-001. In addition, it is also compatible with both macOS 10.13 High Sierra and macOS 10.12 Sierra.
