MAC OS X Leopard was released on October 26, 2007.
LANDesk Support for MAC OS X Leopard
LANDesk Management Suite 8.8
LANDesk Management Suite 8.8 will ship with partial Leopard support.
SLM and Remote Control will not work with the 8.8 release due to these pieces of LANDesk using now deprecated functions inside the Apple OS.
Leopard, like all new Operating Systems, will be fully-supported around 90 days from its initial release.
Currently, LANDesk is scheduled to support Leopard in 8.8 in a post release patch.
8.7 SP6 and prior
There is no support for Mac OS X 10.5.x in prior versions.
