Hey Guys,
I am sorry if I ask a question asked a million times already, but I have read the thread now for over 2 hours.
I was thinking about starting mining. I have mined years ago when it was just a laptop but obviously this is over  

I have no computer background, I don't know how to repair anything or set up without a video lol I just like the idea and hope its kinda plug and play. 
My plan was to buy 1-3 Antminer L3+.  Now I have tried to find how to set it op on solo mining without a pool, could not find any info and landed here.
After reading this thread, I lost all trust in Bitmain. Sounds like the service is shit and the product breaks down non stop....
So here are my questions and I hope someone will find some time to answer.
1)
How do I set up the Antminer (worker) if I want to solo mine LTC?  (I have only found videos where they input the Pool worker under "General Settings")
2)
How do I set up the Antminer (worker) if I want  to mine NVC or Bela or another Scrypt based coin?  (I have not found any infos regarding that. For most of the other coins, there are not even big pools. So I have to go solo/or want to go solo.   And i read that the Antminer are not good in mining Scrypt except LTC)
3)
I use Mac OS X for a couple of years now (again not the tech guy). Is it required to have a computer run and monitor the mining process 24/7?  Or is it enough if I set the miners up, and check them online once a while, using my Laptop for work normally. Or is it required to have a dedicated computer online with the miners if i solo mine.
4)
Do I have to take care of anything, if i got more than one miner? Like linking them together as "one machine" to ramp up the Hashing Power or is it enough if they all mine separately (Of course i know that if they "count as one" its better)
Again, I would really appreciate getting some answers. I will not make this into real profit hunting (breaking even would be enough already), I have to check if my power outlets are able to handle it, I need to check how it is with taxes in my country and my electricity costs way over 29cents/kwh.... But all online calculators are telling me I could make a profit (even tho i don't trust it, otherwise everyone would mine right)
Probably I will buy the next batch anyway since I need to check a lot of infrastructure and laws lol
