We got problem with MacBook Pro. Our problem is that in 50% of the cases our Mac's is not 
roaming. We have to disable the wireless net and on again, then it is ok. It is a problem when student is walking around from classroom to classroom.
We are using AP370 with newest firmware. and we have used the guide from aerohive "high density Wi-fi- design".

Same here, Yosemite didn't help the issue either.

How have you configured the data rates?

Have you disabled the 802.11b data rates?

While being sticky is clearly Apple's issue more than any AP vendor's, you can often compel the client to associate elsewhere by adjusting the data rates so that lower ones are not available and lowering the TX power (just not too far as it will do more harm than good!).

data rates starts with 18mbs
802.11b is disable
tx power is down to 14 db on 5ghz and between 7db and 14 db on 2.4 ghz

remember that we have used the "high density Wi-fi- design". for the design.

Because although an AP can influence the client's decision, the Apple client being unduly sticky here is not the APs decision as OS X does not support 802.11k and 802.11r.

... Oops, and does not support 802.11v!

(802.11k/r/v are the Voice-Enterprise features.)

Looking around, this may have been improved in OS X 10.9.4:  http://www.experts-exchange.com/Networking/Wireless/Q_28389889.html

What version of OS X are you testing with? There, the poster had success contacting Apple.

You really ought to report the issue to Apple then. Presumably, they will only now do any work with Yosemite.

Just want to say we have the same issue with Macbook Pro's running Yosemite only with a different AP manufacturer.  Did anyone ever report to Apple or find a fix?

Wait for 10.10.2, perhaps Apple will be able to fix the wifi and Bluetooth problems!?

Are you using 802.1X? If so, it's worth reading the following article that Apple published as this has implications for both the initial association and when roaming occurs:

OS X: Intermittent delay while authenticating to TLS, PEAP, or TTLS protected Wi-Fi network
http://support.apple.com/en-us/HT203841

I am definitely hoping that 10.10.2 improves the reliability of everything Wi-Fi.

We are starting to see issues on our wireless with PPSK and Guest access on Apple devices.  For guest, the captive portal page doesn't pop.  Sometimes disabling the wireless NIC and re-enabling works.  Sometimes deleting cache and cookies works.  If we reboot the access points, that always fixes it.  As for PPSK, that one we are trying to capture this problem.  Good times...

this has recently come to my attention and is likely a source of Apply connectivity issues
