Having searched online for answers the only real option open to me was to downgrade from OS Mojave to OS High Sierra which I did. I then discovered that the CS6 applications were not useable with Mojave due to 32 bit / 64 bit compatibility issues. They had been working perfectly until I made the mistake a couple of months ago of upgrading my iMac to OS Mojave. These are my Adobe CS6 box pictures I uploaded earlier, I paid a fortune for these Dreamweaver and Photoshop at the time, circa 2014. I'm now running OS High Sierra 10.13.6 - it appears not to matter what OS or browser is in operation. Whilst I'm aware that CS6 itself is considered to be on life support - I'm just a pensioner - although thankfully not yet on life support myself - with just a hobby website so it's not really a viable option to go down the subscription route. I'm trying to get my Adobe Dreamweaver and Photoshop to reinstall and get back to being operational.
