Is it possible and profitable to mine LTC on an iMac 2017? (Radeon 580, 8 gb ram, i5 Processor)?

Is it profitable to mine LTC on Mac?
Any mining software you recommend?

Yes…it’s possible…No… not profitable…you’d be better mining monero (cpu) and Bitcoin gold (gpu) and file coin(hard drive or SSD) and trading for litecoin…
Assuming you keep those parts cool while running the software
