The last time I had install issues with Adobe, they provided install support for free! It’s not cheap software and the support for installing was included.
Go to the Adobe website on safari browser click onto the Mac version of photoshop it should download & in downloads after the download has completed you should find a .dmg double click the dmg file you may have to go to file vault & unlock with your computers password you should be guided through the process & drag the photoshop file into your application folder. When you open photoshop for the first time on your machine you will be given a 30 day free trial. After that you will need to purchase a licence to continue to use the program. I wish you all the success in the future.
