Help with re-installing CS6 on Mac

@Amira25693949qscn,

Ideally, you should use the installation disks (or downloads) you received at purchase along with your valid serial number.  If your machine lacks an optical reader, an external CD/DVD drive can be purchased on Amazon for about USD $20-$30.

I make no guarantees this will work with your license.  CS6 is 10 years out of date, discontinued & unsupported.  You're using outdated software at your own risk.   Follow the VERY IMPORTANT INSTRUCTIONS below.

Failing that, get modern software.

Photoshop Elements or Premier Elements (approx $100, no subscription needed).

Look for CS6 Mac posts by @Nancy OShea. She's posted links many times to the information needed to reinstall CS6 on a Mac running Mojave. 

Something you can check immediately is if TLS 1.2 is enabled on the Mac.

Be aware that CS6 will NOT run on any Mac OS from Catalina onwards. Apple stopped supporting 32-bit programs when Catalina was released.
