Can I use Adobe Subscription on both my iMac and PC Laptop?

I moved your post over from the poorly named Community Help forum, which is for getting help using this forum system, to a better forum.

To answer your question Yes you can install the programs you subscribe to on both Windows and Mac OS X and activate both, Limit of 2 active activations.

Yes you can, so basically you can install on as many computers as you want, activate it on two and use it on one at a time

See the following for official word
