I have been using Adobe Photoshop as my primary image manipulation
program since 1992 on Mac computers. Even since then , I split the main
hard disk in two partitions and I have an operating system on each part.
This method always saves the day when something goes wrong. (Rare)
Lately I keep Mac OS 10.5(Leopard) on one partition and Mac OS 10.7
(Lion) on the other.(For compatibility reasons at least for now).
On 10.5 I work with PS CS3. Can I buy Adobe PS CS5 or PS CS6 as an
update and instal it on 10.7 (Lion) and use either of them when booting
from the Leopard partition or the Lion partition ? Thanks !
And multiple versions of most Adobe programs can coexist just fine, should you decide to run both from the same partition. Most programs do NOT overwrite other versions, but install separately. This can be very useful, where one has a version that they know, while they learn a newer one.
I'm just curious. If you are going to the expense of upgrading to CS6 (a much better product than CS3) why not install it on BOTH partions? As far as I know, the only restriction is using them simultaneously, which presumably you wouldn't be doing. See here... http://forums.adobe.com/message/4142809
