Obs slows down my mac

[CarlosCruzMusiq]

Hi guys, I'm trying to stream on Twitch with OBS/ Streamlabs OBS but it's near impossible.
I´ve got a:

Mac Mini (Late 2014)
3 GHz Dual-Core Intel Core i7
1TB SSD
16GB RAM
Intel Iris 1536 MB video card

You would say that's powerful enough to run OBS smoothly but its not and I have no idea how to solve it.
Is it possible the video card is too weak??
Please please can someone help me out here, very desperately need this fixed asap.

Thanks in advance,
Sincerely Carlos Cruz

you have a system optimized for space and low power usage, not the computationally demanding task of real-time video encoding.
I recommend monitoring hardware resource (CPU, GPU, RAM, etc) utilization to see if your system is being maxed out with your settings

Be aware that your PC is old, and under-powered in general and especially for for the streaming settings you are trying to use. IF it will work (and I don't know that it will), you are likely going to need a simplistic OBS setup, and optimize OS and OBS for an under-powered PC. With that video card, I think you will be looking to optimize the Quicksync encoding setup (assuming that card support such, I'll let you do the research)

For reference, I tried to stream with an Intel i5-6300HQ (2.3GHz 4c/4t circa Fall 2015), 8GB RAM, SATA SSD, Nvidia GeForce GTX 960M [so NVENC GPU encoding offload] and failed as the PC wasn't up to the task (no gaming, just alternating between USB webcam and simple pre-recorded videos, alongside a PPTx slide show window capture, streaming at 720p 30fps with no OBS effects/filters). I’ve learned a lot more about OBS since then, and I might be able to just squeak it out, but wasn’t worth it (to me)

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

I forgot to mention I don't game I only DJ.

Ok, so you don't have game workload in addition to OBS, that's good.
but still - real-time video encoding .... on an old computer. it is doable, if you optimize your setup (OS and OBS) and accept the associated compromises required. You should look for recommendations on OBS setup for under-powered systems

Hi thank you again for the reply. Where should I look for the recommendations on OBS setup for under-powered systems?? Im clueless haha.
