So I was reading through Scott Kelby's book and it suggested that I turn on the 64-bit mode. Well I did, and ever since LR seems to be slowering (not 100% of the time, but more often), as well as crashes upon import. There has been two different imports so far that have crashed while importing. One was about 50 raw files, and the other 4 jpegs. LR crashed about three times while trying to import the raw file import before it finally got them all in. i'm going to try the jpeg import again right now, but it crashed during that as well.

Howdy.

I'm no Geek (I use this term in its best possible sense), but my Windows Vista Home Premium is a 32 bit system. I can imagine it might cause all kinds of trouble if I set Lr to 64 bit.

But maybe not. You could put everything I know about operating systems in a thimble, and still have enough room left over for everything I know about CSS & HTML.

Windows or Mac?

In OS 10.5.6 I run LR2 in 64 bit mode - faster, better, more stable :dunno

MacBook OS X. I turned it back to 32 bit and it's been working great ever since. I know you mentions you have a bit more memory than I do, so maybe that's an issue?

I run my MBP in 64 bit also - it only has 4 Gb RAM

My desktop MacPro does have more than that.

I think I only have 2GB of ram. I do need to upgrade to 4GB as you suggested, just don't have the time nor money right now. Think that will make a huge difference?

Yes, additional RAM will make a big difference. If you don't buy the memory from Apple, it doesn't cost very much these days. In the meantime, with only 2GB of RAM, 64 bit mode won't buy you anything, so just stick with 32 bits. :deal

The bits are used by the operating system to address memory. The biggest number you can express with 32 bits is about 4 GB. With 64 bits the number is ridiculously large. In general, no real point in using 64 bits unless you have more than 4 GB.

Thank you. I knew I needed to upgrade my memory for some other things, but glad I know that it should help with this as well. Now I just need money.

How hard is it to install on the MacBooks? I've installed memory on my old iBook (the first generation ones, with color and the little handle), but other than that I have no experience.

One of the easiest RAM installs of any Mac. If you are familiar with the process it could take as little as 60 seconds. If not familiar, a few minutes. The directions are in the MacBook manual which is also on Apple's site, and there are many YouTube videos of it.
