I have run in to several issues with scanning computers. Particularly Mac's. Here is a few:
1. SD+ can't get the Serial Number
2. yet alone identify a host by that S/N (So, If the host info in SD+ and reality are not 100/100, you can't really scan the network without creating duplicates).
3. Domain part is dropped from Resource Name (hostname.domainx.com is OK but hostname.domainy.com is cut to hostname. This creates several issues).
4. Model is shown as --Choose Model-- in edit mode after the scan.
5. Memory details don't add up.
- SD+: 1024KB+1024KB+1024KB+024KB= 2.0 GB,
  Reality: 1GB+1GB+1GB+1GB= 4 GB
- SD+: 512MB+512MB+1024KB+1024KB+1024KB+1024KB = 2.0 GB
  Reality: 512MB+512MB+1Gb+1GB+1GB+1GB = 5 GB
6. Others

Any change that there is a resolution for any of these out there?
