Am doing a further training in Indesign, Photoshop and Illustrator. Because I need these programs on my mac at home I tried to download the trail version for 30 days of Adobe. Now I was told my operation system OSX 10.6.8 is not supported any more that meant I could not download any of these programs. My mac is approximately 4 years old and I can not afford a new one but I need these programs to practise and do my homework. What can I do?
Upgrade to OS X 10.9 for the latest version of Creative Cloud apps (CC 2015). 10.7 brings you to CC 2014. Apple upgrades are free upgrades the past few versions.
A four-year-old Mac should be able to run those OS X versions. I installed Yosemite (10.10) on a 2008 MacBook Pro and it runs fine.
These are the system requirements for InDesign: https://helpx.adobe.com/indesign/system-requirements.html
But for the latest versions your computer has not the resources. Eligible students can get a substantial discount from Adobe.
For image editing you could use Photoshop Elements.
