an inappropriately named (in the View menu) 'ASIC' miner which is actually configured for any BFL device whether it be FPGA or ASIC (name change to BFL Miner to follow in 1.0.3)

No it shouldn't, thanks for letting me know, it seems I used the wrong Cert, can you please redownload the installer and let me know whether it's verified OK for you now?

Cool, thanks for the feedback it's really good to know where things are and aren't working! Did the update run fine without having to adjust the permissions too unlike the 1.0 release?

I didn't find out about a driver I'd forgotten to package with the 10.8 1.0 version until a reporter at ars technica got in touch with me yesterday to help him get a BFL Jalapeno running  It's really strange getting thousands of downloads without people mentioning when they run in to issues... or perhaps they're special cases.

Hmm that speaks of connection difficulties to the pool of course but it's unusual that SOME work goes through but perhaps other does not. Have you left it running since then and if so what's the reject rate and how often are shares being accepted approximately? It can take the pool a while to show your full speed.

It might also be worth getting a ping and bandwidth measurement from speedtest.net or similar to check whether there are any connectivity problems on your line at the moment?

Woops, typo, meant to say it ran fine without any tweaking, out of the box.

Just tried a different network available here (routed differently) and its the same! Old GuiMiner still seems to work out, though its not using stratum I guess, Ill have to check at home to be sure.

Well the bad news for me is that it seems to work fine at home, so my company must block the stratum ports/interface or something!

After Ars Technica got in touch with regards to running a BFL ASIC on Mac OS I'm happy to report their report:
http://arstechnica.com/gadgets/2013/05/weve-got-a-butterfly-labs-bitcoin-miner-and-its-pretty-darn-fast/

and the setup we used:

After installing the Mac OS 64bit drivers here:
http://www.ftdichip.com/Drivers/VCP.htm

we ran:
./bfgminer -o pool.name.com:port -u username -p password -S bfl:/dev/cu.usbserial-FTWILFLM

I'll be making a specific external device view for MacMiner very soon!

>ssh -D <port> user@host
>./cgminer --socks-proxy 127.0.0.1:<port>

 ... also works well.

Thank you! My first donation I really appreciate it! Let me know if there's anything you'd like worked in to the app.

BTW... it works BEAUTIFULLY with my BTC pool (slush)
