Well, short question, (fairly) short answer: 64bit does only make sense if your machine has got more than, say, 4GB of RAM. Otherwise Reaper can't use more than 3GB (and that's the main benefit of 64bit-operation). And because I think 32bit-Reaper runs more stable on the Mac, I'd recommend this one.

Just curious: Is the Ram usage the only difference between the 32bit and 64bit version? I guess there must be other advantages (CPU usage, etc.)?

Resurrecting this thread because I'm getting interested in this since I've seen what a difference 64bit makes to other apps that I'm running on my macbook pro.

There is a speed increase running in 64bit, something to do with having more registers - but that's the limit of my knowledge.

Kind regards

Program is very fast for me.

I tried the 64-bit version on my MacBook Pro 2010 when I got this last fall, but I got a lot more plugin based crashes. 32-bit Reaper seemed to be a lot more stable, so I've been using it ever since. Don't know if the current version would behave better though.

I think the rule of thumb is that x64 should provide about 10% increase in CPU efficiency (like, a project that used to use 50% will now use 45%). But the increase RAM utilization is obviously the major benefit.
