The only version currently available (other than on the auction market and much of that is counterfeit) that will run on your OS is CS6, and you will have to either buy direct from Adobe for a lot of money (after they explain to you why you shouldn't) or subscribe to Creative Cloud and get the installer from ProDesign Tools because the current version of CC will not install on your system. Frankly, you'd be better off upgrading the hardware and subscribing to CC.
Thank you , Peter! So I´d rather do this...
Not sure which you'd rather do. A perpetual license to InDesign CS6 is around $700, I think, and that Mac of yours isn't going to last forever. While the subscription locks you into a monthly fee, you get a lot of months for $700, and when you replace the Mac you can use the newest versions of ID and stay up-to-date with upgrades.
If you decide to go that way, post back and I'll try to find links for you to get what you need for installers.
In this case I will first look for a new mac and then decide for a subscription. Thanks a lot.
Makes the most sense to me.
I ran the CS6 Creative Suite (ID, PS, AI, FW) on Snow Leopard for a long time. It was rock-solid stable, both the OS and the software. I don't know what kind of Mac you have, but I had a 2011 iMac 27" and it ran like a dream.
A few months ago I had to upgrade my iMac at work, and I was given a brand new Mac Pro tower running El Capitan and the current CC apps. it was a DISASTER. Crashes galore. Rearranged UI elements, both in El Capitan and Adobe products.
If there's a way you can get your hands on a decent full-install package of CS6, and your machine is not more than 5 years old, I would seriously consider it. Yes, it will be a larger up-front expense, but you avoid ALL the various problems inherent with subscription-based pricing models and you also don't have to deal with the many, many new bugs, crashes and silliness that users of CC are constantly having to deal with. You also don't have your documents held hostage by Adobe later if you decide to stop paying them monthly in the future.
I had to wipe the drive, install Yosemite and roll back to CS6 to get system stability and reliability again. Just something to consider.
EDIT: I did a search for CS6 on Amazon.com and found it there. There are also numerous auctions on eBay for the software under $1000.
be VERY careful about purchasing Adobe software from non-approved resellers. Besides counterfeit software, education licenses cannot be transferred, and any version that is part of an upgrade chain must be transferred with all other versions in the chain, and you must obtain a transfer of license from the seller (on a form available from Adobe) for any product that has previously been registered. Make sure you get a money-back guarantee that will be honored.
