Sep 27, 2017 Extra trick: How to free up RAM on Mac with CleanMyMac X. If you have downloaded CleanMyMac, you may also take advantage of its amazing feature — the ability to free up RAM in a few seconds. Try this next time you see “Your system has run out of application memory” message. Go to the Maintenance tab on the left. Click Free Up RAM. The disk cache in OS X can sometimes use a fair amount of the system's RAM, and clearing it can help you figure out how much RAM your applications and system processes are using. Topher Kessler.
Hey there, s.torrance84,Thanks for visiting the Apple Support Communities. If I understand your question, you'd like to know whether the Adobe Creative Suite 6 Master Collection will work in macOS 10.13 High Sierra. I'm happy to help you get some information on that!
Adobe indicates in their support article Installing Creative Suite on macOS 10.12 (Sierra) that: Creative Suite applications are not supported on macOS 10.12 (Sierra) and therefore, many of the Creative Suite installers may not function normally on macOS 10.12.
Since macOS 10.13 High Sierra was released after macOS 10.12 Sierra, it seems as though the same information would apply to High Sierra. However, to be certain I would recommend getting in touch with Adobe. You can check out the system requirements for their Master Collection here:
