Offer some real management tools, don't require an Apple account to do everything on your computers, etc, etc, etc.
Or honestly, you know, just... fix the broken crap. Take all the stuff that Apple does offer for business, and fix the bugs.
Like take care of the bugs in Mail that cause it to not sync properly when mailboxes hit a certain size. Fix the bugs with Open Directory, Profile Manager, and mobile user account syncing. Speed up access to file servers, and fix the SMB problems that cause files to become locked and Finder to crash. Some of these problems have existed for years, and they're just not getting fixed.
If they can lock that down, here are some more things they can do: Start supporting server hardware again. If they don't want to make their own server hardware, just provide some licensing route to allow you to run OSX server on ESXi or HyperV on non-Apple servers. Throw some money into OSX server development. Either forget about providing email/calendar/contact/chat, or invest enough in it to make it competitive with Exchange and Google Apps. Integrate something like Munki or Casper to provide configuration management and updates for 3rd party applications.
They're want to partner with Cisco...? Fine. Partner with the Meraki division, and make co-branded Cisco/Meraki/Apple networking equipment. Create an integrated cloud management platform that manages routers, wireless access points, switches, servers, NAS devices, virtual machines, MDM, and really the whole network to be controlled from an single-pane-of-glass. Have Apple assist in the hardware and UI design, and integrate it with the now-fixed Profile Manager, Open Directory, and Munki functionality that's been added to OSX server. Then have it support Windows, too.
But of course, they're not going to do any of that. They won't do anything as mundane as fixing the bugs in the SMB support, and they won't do anything as ambitious as trying to make Mac OSX Server competitive with Windows or pushing cloud management forward. Instead, they're going to continue making incremental upgrades to their consumer-centric features while striking buzzword-friendly deals with Cisco and IBM to provide the illusion that they care about the Enterprise.
