The last Apple we had was a purchased mac mini for Buildbot and later opened up for Jenkins,
for Jenkins though it was not that reliable and how constant connectivity issues.

Not true. More on this below.

Thanks, if not already, I’ll let our host donators of those boxes Yahoo! know about that.
We started sending notifications of disconnected boxes to mailing lists, but got complaints,
so that has stopped.

As above, not true, this page explains more:-

https://cwiki.apache.org/confluence/display/INFRA/Jenkins+node+labels <https://cwiki.apache.org/confluence/display/INFRA/Jenkins+node+labels>


I have been very careful with the wording on that page in each labelled section.

tl;dr here are 4 sections on that page:-

1. The Hadoop Nodes H0-H9 - Hadoop and related projects have priority 
2. H* Nodes that are generic and available to all (Not specifically Hadoop and related) 
3. The generic ‘ubuntu’ nodes - everybody is welcome
4. Miscellaneous nodes - Everybody is welcome!

That is a minimum of 27 nodes at your disposal and this number is set to increase even further
soon.
H0-H9 are priority for Hadoop and related projects, but it does not mean you can not use other
nodes, you can, 
‘everybody is welcome’ includes Hadoop!

In other words, feel free to change your job labels from ‘Hadoop’ to ‘Hadoop &&
ubuntu’ etc...

;)

With the exception of the Nodes hosted by Yahoo! and other donators where we don't have console
access, pretty much.
