CS6 vs Mac OS 10.13 High Sierra

By all means buy a new Mac but keep the old one to run your old apps reliably.

CS6 and earlier programs have not been tested and will not be updated for Mac El Capitan or later operating systems

-which means that you try to use CS6 and earlier at YOUR risk of having problems due to Apple updates

-Apple did not maintain backward compatibility with old programs in El Capitan or Sierra

--Adobe has a workaround to Apple's problem of not maintaining backward compatibility

--READ HERE https://forums.adobe.com/thread/2301916 for an Adobe solution to installing old programs, including a link to installing the old Java runtime that is required

Owners of old programs simply have problems with Mac El Capitan/Sierra... none of which is Adobe's fault... Adobe did not change your old program to make it stop working... Apple changed their operating system and THAT is why your old programs won't work, not because of anything Adobe did... Also... every time Apple issues an update, there is the risk that an old program that HAS been working will STOP working... bottom line, old programs require a matching old operating system

hi,

sierra (os 10.12) and high sierra (os 10.13) are not compatible with older software, but adobe's posted a work-around:  https://helpx.adobe.com/creative-cloud/kb/install-creative-suite-mac-os-sierra.html
