I have an older Mac (10.6.8) not suitable for upgrade. Lightroom 4 is the latest compatible version. Does it make sense to get LR 4 now? WIll I be able to upgrade (to LR 5 or 6) when I get a new computer?
Where do you plan to get Lightroom 4 from?
Adobe no longer sells it.
If you can find a copy of LR 4 somewhere and Adobe accepts the serial number for licensing it, then you can use that serial number to get the upgrade price for a future version of LR. You can for LR 5, anyway, and I’d expect LR 6 to be the same.
You will be able to upgrade to 5 or 6 when you get your new computer if you buy the FULL Lr4 now. (I see it is still available in several places on Amazon) It all depends if you need Lr now and how long it will be before you upgrade to a new computer.
