download of indesign and co. is not possible with my iOS Sierra 10.12.6

[#1]

Hi community

On my mac (Late 2015) with macOS Sierra Version 10.12.6 I cannot download all the apps (indesign, photoshop, co.) I already informed myself on the adobe help pages, but in my creative cloud i don't have the possibility to download older versions (like it says on helpx.adobe.com). I already deleted and installed the creative cloud again but this hasn't helped.
It says just that I have to update my computer to a new version, what is impossible with the late 2015 mac.

Can u help me with my problem?
It's super annoying, that I can't download the apps, cause I pay for the monthly abo.

Thank you!

i don't think there's any 2015 mac cannot be upgrade it's os.  it would have to be older than 2006 to have serious upgrade constraints.

upgrade your os.

Direct Download Links https://prodesigntools.com/tag/ddl MAY help
-you MUST do what it says in Note: Very Important Instructions
-https://prodesigntools.com/adobe-cc-2015-direct-download-links.html#download-instructions
-this will only work until Adobe completely removes the old version(s) from the server
.
When you do have a download, be sure to copy it to at least one external device
-a usb flash drive or hard drive, or write to a DVD

According to this Apple web page you are wrong to say you cannot update your computer. https://support.apple.com/en-gb/HT210222

Of course you will need ALL NEW APPS, Catalina and Big Sur will not run apps older than 2020.

Two more things

1. Sierra is the system that came with a late 2015 iMac. There have been many upgrades.

2. Don't look for iOS upgrades. iOS never ran on any Macs, it is for iPhone and iPad only. You run macOS.

I'm afraid there is no workaround.  You MUST have macOS Mojave or later to use Creative Cloud.

See minimum system requirements below. Check each one because they vary by product title.

Adobe expects customers to have the latest operating systems  -- no more than 2 versions back  -- for security reasons.
