 So it looks like I'll
have to buy a memory card from another manufacturer, but which one?

I regret I've no idea about new stuff. My P&S toy is 6yo with the original 10Meg card.

It looks like you will have to approach this by eliminating one component at a time. For my own example with the CF card (SanDisk), while I couldn't mount the card using a SanDisk reader, I had no problem mounting it using an el-cheapo pocket reader. But then I didn't have any possible USB1/USB2 complications, because I plug the reader directly into the Mac's USB2 port. Perhaps your retailer is prepared to let you take a reader and a card on spec for trying out combinations? I used to be able to find pc retailers who'd let me try memory sticks and all kinds of pc cards before I made final decisions.

If your problem remains, this is a UK photography forum with Mac users that my nephew recommends.

It's pretty busy, so your question might get looked at soon.

I hope your Westnet experience will be as good as mine continues to be. And I don't even get paid to do this ad.

amicalement,
