Hey Mr. No Sox,

I have to say I envy your hash rate there. Hackintosh or what?

The reason it's not working with LTC is that poclbm doesn't support it, if you go to the view menu you can choose cpuminer (which only supports LTC) and/or bfgminer which supports LTC with the --scrypt option

NB cpuminer requires http:// before the pool

Yeah, It's a hackintosh with two 5870s. Tried BFG Miner and it seemed to hang so I ran it through Terminal and sure enough I still get that "Trace/BPT trap: 5" error. I really wish I knew what was causing that. A Hackintosh running 10.8.3 *shouldn't* be any different than any other Mac running it yet I seem to get this error with any scrypt miner I try to run.

That hash rate is kinda meh for BTC... If I could get that working with scrypt I might be able to do pretty doggone well with LTC.

[Anonymailer]

It's some kind of missing library problem, though if it's not telling you which it's probably something out of the libraries included with the system.

Only thing I can think to recommend is opening the bfgminer binary in Textedit and making sure all the files listed at the top exist, but like I say it's probably a different library that's missing or not loading properly.

[MrNoSox]

Excellent. I shall try that! Another question... Can you tell me about the two hash rates that it shows? Why is one approximate and in parentheses? Which one is my actual hash rate?

This is all I could see at the top that is legible.

They all seem to be in place. That last little part though "libblkmaker/.libs" it shows up on it's own line and I don't know what that is or if it's just part of the line above it.

Anyway, I guess it would be like shooting in the dark to find the library that's missing. Maybe one day I'll come across that little bugger.

[Anonymailer]

The first rate is your 'actual' has rate, whereas the one in parentheses is calculated by number of shares solved over time which varies due to luck so it's not unusual for that one to be far higher or lower than your actual hash rate.

If all those libraries are there I'm afraid I can't help, maybe you could try to get the libraries from another install and copy them across but hackintosh systems can have some hard to diagnose peculiarities so maybe just mine BTC on the GPUs and LTC on the cpu… in my experience it's hard to get a good hash rate GPU mining LTC on a 5770 with Mac OS anyway - doesn't seem to want to go much faster than the Xeons in my Mac Pro!

[Anonymailer]

Hey everyone,

Just working out the wrinkles on the BFL miner interface, and not really sure how to make various output aesthetically pleasing. So I figured I'd ask everyone what they want. What are the most important data points to be highlighted for you and given the choice how would you prettify the output? Here's where the beta is at the moment:

[Anonymailer]

version 1.0.2 released

Changes:
reduced memory usage, limited the size of the log
interface improvements for bfgminer including a fix for multiple flags (e.g. -w 64 -I 5)
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)

[LaserHorse]

Excellent work - thanks so much for this!  The new update is fantastic.

Happy to help if you need feedback for future updates and/or UI changes.

[Anonymailer]

Thanks, glad to hear it's working well for you!

Right now I'm testing an install of a p2pool node with a 1% pool fee to see whether it can take the load if you'd like to help test it out! If it all goes well it'll be an auto-configure option in 1.0.3 - unfortunately it's only working for CG/BFGMiner windows at the moment not the main MacMiner (poclbm) window.

The address is 176.58.119.218:9332
username is your BTC address for rewards
password can be anything

it's connected to the wider p2pool network and payouts are generated every time the network finds a block, which is a few times a day.

[emunebtk]

Just tested pool and got same error as before running Lion 10.7:

Error opening terminal: unknown.

[Anonymailer]

Can you make sure -T is set in cgminer window please? Do you know whether the pool is a p2pool node? It's the same port and that's the same error I got trying to connect to one with MacMiner (poclbm) window but it worked with cgminer window in 10.7 - the only thing is needing the -T option for it to load in app, I should have and will hard code that in but it's there so you can run cgminer from the terminal with the text user interface if you prefer to!

[emunebtk]

!!! -T made a huge difference. Not sure where I missed reading to add that command. Thank you. For the pool i am using the 9332 longpool port started up then a few seconds later just stopped? I then put in their Stratum 3333 port and we are going now with :

Waiting to see what happens on the accepting side but thinking because I do not have a stratum proxy this wont do anything?

[emunebtk]

no shares accepted via 3333 so going back to 9332 port and this is how it starts using -T option:

 [2013-05-21 16:04:26] Started cgminer 2.11.4
 [2013-05-21 16:04:26] Probing for an alive pool
 [2013-05-21 16:04:27] Long-polling activated for http://mining.usa.la.hypernova.pw:9332/lp

then just stops? Now i see it says starting cgminer 2.11.4? I have had no luck compiling a 3.1.1 for Lion at this time.. maybe thats the issue?

[Anonymailer]

I think I put -T in the ? Window, possibly at the beginning of this thread… I will fix that for 1.0.3!

That hash rate doesn't look healthy though, it should only be measuring in Kh if you're using --scrypt for litecoin mining or the connection to the server is going wrong somewhere. I don't want to push the big pools, but maybe you could try one of those? I use mining.bitcoin.cz and the p2pool i'm putting together so those are the only BTC pools I can say with certainty couldn't be the problem, and I suspect it's a pool connection issue going on here..

it's still 2.11.4 just as I've been spreading my focus rather broadly at the moment, I will probably replace it in 1.0.3 with BFGMiner though as CGMiner won't compile with USB device function on a Mac

[emunebtk]

I should of mentioned I am LTC mining here. Do I need to add any more options besides -T to make litemining work in Cgminer? A little over a week into mining and learning command line so not total newbie but pretty much still one. If I use GuiMiner OpenCL miner I get about 150 mhash/s when connecting to this LTC pool on a Radeon 5770..does that sound right?

[Anonymailer]

ah yes you'll need a space and then the --scrypt option, and you might want to play with -I 4 (intensity (number) goes from -10 to 14 and the higher the harder it works. I think around 8/9 is about as high as I'd ever push the same card. also the -w 64 option try 64/128 see what works best for you.

150Khash sounds about right for LTC mining… 150Mhash sounds about right for BTC mining… although it can get a bit faster

[emunebtk]

where or how do I go about adding the scrypt option? In the CgMiner options field or in a file somewhere else?

Mining BTC now on your Cgminer is working perfectly thru your pool as well as others like BitMinter,etc with your help Thank you! If only it would recognize the XT1900 now but we are at least off to a working start!  win

just use -T --scrypt in options instead of just -T if you're connecting to a LTC pool. I don't really like to mine LTC as it seems to have a lower reward and higher strain on the computer I'm using especially on a Mac, but it should work! As long as you don't mind putting a strain on that 5770.

An XT1900 is too old for mining but if you've got them both you can do what I do and run the monitor through the old card to get more mining power on the 5770!

On another note…

My p2pool seems to be running right below the server's memory limit most of the time and bitcoind crashed while I was asleep probably because of that, I've lowered the max connections for bitcoind and if it's still not stable I'll upgrade it. Thanks for testing it!

[emunebtk]

When I add the --scrypt to the options i end up getting this error ?:

[2013-05-22 12:47:28] /Applications/MacMiner.app/Contents/Resources/cgminer/cgminer: --scrypt: unrecognized option
[2013-05-22 12:47:28] /Applications/MacMiner.app/Contents/Resources/cgminer/cgminer: --scrypt: unrecognized option

and yes.. very good point! I have read though somewhere that an xt1900 will work to mine on a PC its just not the best kind like the nvidia cards being much slower? or is it they just wont work at all and should stop trying? I have an open slot in a slower pc mining setup that was hoping to ramp up with this by somehow flashing to a BIOS but since I have never done that procedure and can't find instructions from going from mac to PC then I may just stick with your plan of using it as the monitor card. The reason I switched to a 5770 recently was the fact that FinalCutProX updates stopped working on the x1900 which forced me to get the 5770. Because this mac is also a edit machine I am really only mining on it half of the day when it is not being used so switching monitors to the old card wouldn't mess being able to still use FCPX right? I guess only one way to find out. One last GPU ?..When i installed the 1900XT back into the mac pro it popped up with some PCI Lane Width options for the 4 slots..you wouldnt happen to know which options I select? The Image looked like this: http://km.support.apple.com/library/APPLE/APPLECARE_ALLGEOS/HT2838/HT2838_1.jpg

If you need the actual screenshot of my options let me know. Does it matter that i put them i slot 1 and 3? or does the 2nd need to go in 2? does it matter? right now the 5770 is on #1 with a 16x lane width and 1900XT on port 3 with a 4x Lane Width I believe..so many variables! thanks for helping me out Not much info about osx gpu's out there...

Just started your pool up and it seems to be running great at the moment..will keep it going on here for a bit for the BTC

Figure my machines arent the most powerful so really no point in trying to get into the BTC mining at this late in the game with ASICs popping out any day. Which was my motivation to switch to LTC before everyone else did and get a little head start. So mainly trying to mine Litecoin but still trying to get that 1 BTC before all hell breaks loose with the ASICS. Only .07 to go
