Maximum number of entries

@Franko: It's a fair question. Not really. I mean, it depends on the age/power of the Mac you're using, and certainly 500 items will take more to decrypt and process than, say, 100; but most of us here have thousands of items in 1Password in 2019, and that's not uncommon among users either, so I think you'll be okay. I just can't say if it will be different, comparatively speaking, to what you were using before, given that I don't know anything about their encryption methods. If nothing else, it should be relatively easy to give it a try and see. :)

@Franko - on behalf of brenty, you're quite welcome -- feel free to ping us again if anything seems amiss or takes what you would consider an unusually long time. :)
