And I don't know if you can convert from Enterprise data files to QBO yet, so you'd have to check that. Your one other option would be QuickBooks Online, but that is only if you can get by without the Enterprise features that QBO doesn't have. Know Company File Compatibility between QuickBooks Versions Intuit has. The end result is that the Mac version is behind the Windows version in terms of features, and there is no Enterprise client for Mac. QuickBooks Mac is a different software package than all of the others and is not. It got cancelled a couple of times and then resurrected. The Mac version split off from the Windows version a long time ago. Using TS means you only have to upgrade the one installation, and you don't have to deal with the mess of the database hosting. Costs a bit for the licensing, but worth it in saving you the hassle. Terminal Services is your best bet, and it is easy to setup. If I set up a Terminal server with Server 2008 R2 SP1 would I be able to access the hosted application from a mac, I don't have any experience with Terminal Services and haven't read the documentation yet. I would prefer to just do VM's or Terminal Server but most of the Macs are PowerPC and I'm pretty sure that you can't use VMware on that architecture.
