Note: I put xmr-stak-amd into Applications folder, change that accordingly if yours is not.
Note2: I ignore the idle status when Firefox, VLC or 5KPlayer are opened, so it won't do GPU-mining and lag my mac while I'm watching YouTube or videos.

i checked the oppenssl folder and as expected the dylib is there.
i also tried to move the xmrstak folder to applications without change.

Please help me

I understand this has been encountered before and the solution was to compile a version without libmicrohttpd as pre Sierra Macs do not have this part (_clock_gettime) of the posix capability.

Could you please provide us with a version of xmr-stak-cpu (2.4.x) compiled without libmicrohttpd dependancy?

Thank you!

Thanks

I was able to compile my own using your instructions on the GitHub thread though:
https://github.com/fireice-uk/xmr-stak-amd/issues/121

Thanks again for your help.

Possible that you maybe make a Nvidia 2.4 version too? thanks a lot

I was wondering is there any easy way to turn up the intensity. I have tried the CPU and the CPU/GPU mining on my iMac. However the hash rate is not very high. It looks like on the CPU miner I am hashing three threads (if my lingo is correct) all at about 50-60 hash per second. (the CPU/GPU didn't significantly increase the hash rate so I have been using the CPU only).

I have also been using a mobile mining software and on my iPad Pro I can do 8 threads at about 60. So I can mine twice as much on my iPad Pro as compared to my iMac. However I would think that the Mac should be able to hash more. I suspect it is because the XMR-stak for Mac is set to a lower power.

The iMac is a late 2015 processor is 3.3 Ghz intel core i5. Memory 8GB 1867 MHz DDR3. Graphics AMD Radeon R9 M395 2048 MB.

Thanks for the help! Again sorry if some of my terminology is not correct, I am new to the mining.

Also...minexmr.com cant find my account, or says I'm timed out. What's going on?

Is anybody else having this issue? How do we address it? Thanks!

Everything is stable, though, I would like to bump up the hashrate to what I see on Windows ~1900... will keep experimenting.

I wanted to ask as I've searched the forums but can't seem to dial into where to adjust my cpu settings. As in affinities and so forth. Might you guys know where I can find that settings file? Or what it's called?

Hope all is well, i took your advice and never mined on my old HD graphics and only CPU mined.

OSX 10.13 brings allot more support and apparently AMD RX range will plug n play.

I have a old style mac pro, i know you recomend not to mine with AMD on macs due to the heat but the old cheese greaters have much more airflow and cooling over say a imac so was considering upgrading to a AMD RX580 and giving it a go.

I see here you have compiled for AMD and CPU http://macminer.fabulouspanda.com/commandline/xmrstakamd/

I have been compiling my own using the instruction given from xmr stak but they only give instructions for Nvidia or CPU only.

Would you mind explain the steps needed to compile with AMD support?

For Example CPU + Nvidia:

brew tap caskroom/drivers
brew cask install nvidia-cuda
brew install hwloc libmicrohttpd gcc openssl cmake
cmake . -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOpenCL_ENABLE=OFF
make install

CPU only:

brew install hwloc libmicrohttpd gcc openssl cmake
cmake . -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DCUDA_ENABLE=OFF -DOpenCL_ENABLE=OFF
make install

Something else i was going to run by you, have you ever considered switching from xmr to another crypto? XMR-STAK supports several others. Or perhaps different miner altogether, but i believe the hash rates are much lower or efficient to mine much else on a mac, i may be wrong.

I was going to play with ubuntu on a mac but never got round to it.

Thanks again.

It's a 2x 2.4 Xeon.

Does 330 h/s sound about right? is there anything i can do to boost it a little more.

Just saw a previous post from someone with a 2016 iMac getting around 700 h/s

The cpu is more modern but the mac pro surely wouldn't be that far behind with 8 cores?

I'm using the new xmr-stak 2.2.0

Normal HD 8gb memory, amd 5770 but it's disabled in the config because there is no guid yet to enable it, although i can't see it producing much more than 130 h/s after looking at other stats.

I'm on a mac 5,1 with a fresh Radeon RX580, on 10.12.x
I got some questions:

• I've tried the original settings. Around 300 H/S and Mac unusable as you said in other topics. With 1048 as difficulty, I can have 550 H/S. Mac unusable of course. With that in mind, do you think there would be a setting that allows me to use my mac (net, office and nothing fancy) while mining with my GPU ? For instance, If I mine Peercoins using GPU Miner, it does mine, around 1 GH/s and I can used my mac for simple operations.. (net, office, excel, etc...)

-75% of the time, after it said that I'm connected to the pool, I got the error "SOCKET ERROR - CALL error: Timeout while wang fr rpy. - Pool connection lost. waiting 10 s before retry (attempt 1). and of corse, no mining... I got understand why... (I'm mining on minergate right now... mainly because I'm used to mine there). The settings in config has no effect no this... (and of course it worked with the pool settings several times before that happens)

thanks for your time and knowledge !
